Extending Beacon to Hindi: Cultural Adaptation Drives Cross-Lingual Sycophancy

Extending Beacon to Hindi: Cultural Adaptation Drives Cross-Lingual Sycophancy Sarthak Sattigeri ssattigeri65@gmail.com February 3, 2026 Abstract Sycophancy, the tendency of language models to prioritize agree- ment with user preferences over principled reasoning, has been identi- fied as a persistent alignment failure in English-language evaluations. However, it remains unclear whether such diagnostics generalize reli- ably across languages and cultural contexts. In this work, we extend the Beacon single-turn forced-choice syco- phancy diagnostic to Hindi through a controlled three-condition design: English original, Hindi literal translation, and Hindi culturally adapted prompts. We evaluate four open-weight instruction-tuned language models on 50 prompts per condition, enabling preliminary separation of language encoding effects from cultural adaptation effects. Across all models, sycophancy rates are consistently higher for cul- turally adapted Hindi prompts than for English, with absolute differ- ences ranging from 12.0 to 16.0 percentage points. A decomposition on a representative model (Qwen 2.5-Coder-7B) shows that cultural adap- tation (∆ = 14.0%, 95% CI:[4.0%,26.0%]) accounts for the majority of this gap, while language encoding contributes minimally (∆ = 2.0%, 95% CI:[0.0%,6.0%]). Category-level analysis using a simplified epistemic taxonomy (fac- tual, opinion, advice) reveals that advice prompts exhibit the largest cross-lingual differences, with deltas reaching 20–25 percentage points and achieving statistical significance in two of four models. Advice prompts exhibit the largest differences (20-25p), achieving statistical significance in two of four models despite limited category-level sample sizes (n=15-20). These preliminary findings indicate that alignment behaviors measured in English may not transfer uniformly across lan- guages and that culturally grounded prompt framing may play a sub- stantial role in agreement-seeking behavior. We release all datasets and evaluation code to support replication and extension. 1 arXiv:2602.00046v1 [cs.LG] 19 Jan 2026 1 Introduction Large language models are increasingly deployed in settings that require balancing helpfulness with factual accuracy and principled reasoning. Prior work has shown that this balance is often imperfect, with models exhibit- ing sycophancy—a tendency to agree with user preferences even when such agreement conflicts with well-grounded responses. Measuring and under- standing this behavior is essential for evaluating alignment. Beacon introduced a single-turn forced-choice benchmark that isolates sycophantic behavior independent of conversational context. By framing prompts as binary choices between a truthful response and an agreement- seeking alternative, Beacon enables controlled measurement of the trade-off between accuracy and obsequious compliance. Evaluations using this frame- work demonstrate that sycophancy is a stable and measurable phenomenon in English-language models. However, alignment diagnostics remain overwhelmingly English-centric, leaving open the question of whether behaviors measured in English general- ize to other languages and cultural contexts. Given the global deployment of language models, this limitation raises concerns about the external validity of existing benchmarks. In this work, we extend the Beacon framework to Hindi, a widely spoken Indo-Aryan language with over 600 million speakers, as an initial exploration of cross-lingual sycophancy patterns. We construct a Hindi sycophancy benchmark following Beacon’s original protocol and adopting a simplified three-category epistemic taxonomy (factual, opinion, advice) designed for cross-lingual transfer. Prompts are culturally adapted while preserving the semantic structure required for forced-choice evaluation. Using a controlled evaluation setting, we measure sycophantic behav- ior in Hindi and compare it with matched English prompts evaluated on the same models. We additionally evaluate a translation-only baseline on a representative model (Qwen 2.5-Coder-7B) to begin disentangling language encoding effects from cultural adaptation effects. Our results reveal con- sistent cross-lingual differences across four instruction-tuned models, with sycophancy rates 12–16 percentage points higher in Hindi than in English. The single-model decomposition suggests this gap is primarily attributable to cultural adaptation rather than language encoding alone, though limited sample size (n=50) and single-model baseline evaluation preclude defini- tive quantification. These findings underscore the need for language-aware alignment evaluation. While sample size and single-model decomposition limit precise quantification, the large effect sizes and directional consistency 2 provide robust evidence for the phenomenon.

While effective in improving conversational fluency, such training regimes can inadvertently encourage models to prioritize user agreement over factual accuracy or principled reasoning. This behavior, referred to as sycophancy, has been identified as a distinct alignment failure mode [Pandey et al., 2025]. Prior work has documented cases in which models defer excessively to user assertions, particularly in subjective or socially sensitive contexts. Re- lated phenomena have been discussed in studies of truthfulness [Lin et al., 2021], over-alignment, and socially compliant behavior [Perez et al., 2022]. However, these behaviors are often examined indirectly and embedded within broader analyses, making it difficult to isolate sycophancy as a measurable construct. Beacon [Pandey et al., 2025] introduced a focused diagnostic framework that isolates sycophantic behavior through a single-turn forced-choice bench- mark. Each prompt presents a pair of candidate responses: one that is factually grounded but potentially confrontational, and another that aligns with the user’s stated preference while sacrificing accuracy. This design enables controlled measurement of the trade-off between truthfulness and 3 agreement, independent of multi-turn conversational dynamics or refusal behavior. Using this framework, Pandey et al. show that sycophancy is a sta- ble and scalable phenomenon that increases with model capacity and de- composes into linguistic and affective subcomponents. The study further demonstrates that prompt-level and activation-level interventions can mod- ulate these biases, suggesting that sycophancy reflects systematic properties of learned representations rather than superficial prompting artifacts. Despite these advances, existing sycophancy evaluations remain over- whelmingly English-centric. Prior multilingual benchmarks primarily focus on general reasoning or task performance rather than alignment behaviors [Hu et al., 2020]. As a result, it remains unclear whether sycophantic tenden- cies measured in English generalize across languages and cultural contexts. Our work directly addresses this gap by extending the Beacon framework to Hindi, enabling controlled cross-lingual evaluation under matched exper- imental conditions. 2.2 Hindi Evaluation of LLMs Evaluation of large language models in Hindi has primarily focused on cross- lingual generalization, task performance, and robustness under translation. Benchmarks such as XTREME [Hu et al., 2020] and its extensions evaluate multilingual capabilities across tasks including natural language inference, question answering, and sentence classification, with Hindi included as a target language. These benchmarks assess whether representations learned from high-resource languages transfer effectively to Hindi, but they do not explicitly probe alignment-related behaviors. Other work has examined instruction following and reasoning perfor- mance in Hindi through translated variants of English benchmarks, often using machine-generated or post-edited datasets. While these approaches provide useful signals about linguistic competence, they typically assume that behavioral properties such as truthfulness, deference, and social com- pliance transfer uniformly across languages. More recently, multilingual safety evaluations have highlighted dispar- ities in model behavior across languages, particularly in toxicity detection and content moderation. However, systematic evaluation of sycophantic behavior in Hindi remains limited. Existing studies either rely on direct translation of English prompts or conflate linguistic difficulty with behav- ioral misalignment. In contrast, our work focuses specifically on evaluating sycophancy in 4 Hindi by adapting a single-turn forced-choice diagnostic to culturally grounded scenarios. This allows separation of language effects from alignment behav- ior, enabling targeted analysis of whether sycophantic tendencies observed in English persist under Hindi linguistic and cultural contexts. 2.3 Indian Languages and NLP Natural language processing for Indian languages presents distinct challenges arising from linguistic diversity, script variation, and data scarcity. Hindi, while one of the most widely spoken languages globally, remains underrep- resented in high-quality, task-specific evaluation benchmarks compared to English. Many Indian languages exhibit rich morphology, flexible word or- der, and frequent code-mixing, complicating direct transfer of models and evaluation methodologies developed for high-resource languages. Prior work in Indian language NLP has focused largely on foundational tasks such as machine translation, part-of-speech tagging, and text classi- fication, often using datasets derived from parallel corpora or government sources. Recent multilingual benchmarks, including XTREME [Hu et al., 2020], incorporate Hindi and other Indian languages to assess cross-lingual generalization, but primarily emphasize task performance rather than be- havioral properties of model outputs. Efforts to evaluate instruction following and reasoning in Indian lan- guages have typically relied on translated versions of English benchmarks. While such approaches provide useful signals about linguistic competence, they may obscure culturally specific interpretations or social norms that influence model behavior. Moreover, translation-based evaluation risks con- flating alignment failures with artifacts introduced during translation. Safety and alignment evaluations for Indian languages remain compara- tively sparse. Existing work on toxicity and harmful content detection has shown that models may behave inconsistently across languages, suggesting that alignment properties do not uniformly transfer from English. However, systematic evaluation of subtler alignment failures, such as sycophancy or undue deference, has received limited attention in Indian language contexts. Our work contributes to this emerging area by providing a targeted eval- uation of sycophantic behavior in Hindi using culturally grounded prompts and a controlled forced-choice diagnostic. By situating alignment evaluation within the linguistic and cultural context of an Indian language, we aim to complement existing multilingual benchmarks and highlight the importance of language-specific analysis in AI safety research. 5 3 Methodology 3.1 Dataset Construction We construct a Hindi evaluation dataset by extending the single-turn forced- choice framework introduced inBeaconto a non-English setting. The ob- jective is to preserve the diagnostic properties of the original benchmark while adapting prompts to a Hindi linguistic and cultural context. Prompt Design and CategoriesWhile the originalBeaconbenchmark organizes prompts into five sociolinguistic domains, we adopt a simplified three-category taxonomy to improve cross-lingual transfer and reduce cul- tural ambiguity in annotation. Specifically, each evaluation item is assigned to one of the following categories: (1)Factual, consisting of questions with a well-defined correct answer; (2)Opinion, involving subjective judgments grounded in underlying facts; and (3)Advice, comprising practical or normative guidance scenarios. This simplification facilitates clearer annotation across languages while preserving the core diagnostic objective of measuring agreement-seeking be- havior under differing epistemic conditions. Synthetic Prompt GenerationInitial prompt candidates were gener- ated using a large language model (Claude Opus) to produce diverse, single- turn scenarios reflecting common opinionated or value-laden statements in Hindi. Model-generated prompts were treated strictly as drafts and were not used directly without human review. Human Annotation and ValidationAll prompts and candidate re- sponses were manually reviewed and edited by two annotators to ensure grammatical correctness, semantic clarity, and cultural appropriateness. Human annotators verified that each forced-choice pair presented a clear distinction between a sycophantic and a non-sycophantic response, consis- tent with the criteria defined inBeacon. A total of 50 finalized Hindi evaluation items were retained. Inter- annotator agreement measured during the validation phase ranged from 78% to 84% across models, indicating substantial but imperfect consistency in identifying the intended non-sycophantic response. Disagreements were re- solved through discussion and revision. 6 Translation-Only BaselineTo disentangle language effects from cul- tural adaptation effects, we constructed a translation-only Hindi dataset consisting of literal translations of the English prompts without cultural rewriting, translated by a single bilingual annotator. This baseline enables direct comparison between: (1) English original, (2) Hindi literal translation, and (3) Hindi culturally adapted conditions. We did not perform systematic back-translation validation, though spot checks of randomly selected items confirmed semantic equivalence with English originals. Final Dataset PropertiesThe final dataset consists of 50 single-turn Hindi prompts with paired responses, distributed across three epistemic cat- egories: 15 factual prompts, 15 opinion prompts, and 20 advice prompts. All items are designed to be answerable without external context and to minimize ambiguity unrelated to sycophantic behavior. Matched English prompts follow the same distribution and semantic structure. By adhering closely to the original dataset construction protocol ofBea- conwhile incorporating culturally grounded Hindi scenarios, this dataset enables controlled cross-lingual evaluation of sycophancy under matched experimental conditions. 3.2 Evaluation Metrics We adopt the evaluation protocol introduced inBeaconto quantify syco- phantic behavior in a controlled and interpretable manner. Each evalua- tion item consists of a single prompt paired with two candidate responses: one non-sycophantic (factually grounded or principled) and one sycophantic (preferentially agreeing with the user at the expense of accuracy or reason- ing). Sycophancy RateFor each prompt, a model is considered sycophantic if it assigns higher likelihood to the sycophantic response than to the non- sycophantic alternative. The primary metric reported is thesycophancy rate, defined as the proportion of prompts for which the model exhibits this preference. Lower values indicate stronger resistance to agreement-seeking bias. Category-wise AnalysisIn addition to overall sycophancy rates, we an- alyze behavior across the three epistemic categories—factual, opinion, and advice—to examine how agreement-seeking bias varies with question type. 7 Human AgreementTo assess dataset reliability, we measure human agreement as the proportion of evaluation items for which annotators consis- tently identify the intended non-sycophantic response. This metric reflects the clarity of the forced-choice distinction and serves as a sanity check on prompt construction rather than a measure of model performance. Cross-Lingual ComparisonFor cross-lingual evaluation, sycophancy rates are compared between Hindi and matched English prompt sets evaluated on the same model. Differences are reported in absolute percentage points. Two-proportionz-tests are used to assess statistical significance, with boot- strap confidence intervals computed for the three-way comparison. All metrics are computed using single-turn evaluations without conver- sational context, following the originalBeaconmethodology. 3.3 Models and Baselines To assess whether sycophantic behavior and cross-lingual differences are con- sistent across model families, we evaluate four publicly available, instruction- tuned large language models with comparable parameter scales but differing training objectives and architectural choices. Evaluated ModelsThe following models are evaluated: •Qwen 2.5-Coder-7B-Instruct, a code-oriented instruction-tuned model with strong adherence to structured output formats; •Mistral-7B-Instruct, a general-purpose instruction-tuned model widely used in alignment research; •Llama 3 8B Instruct, a conversationally optimized model empha- sizing instruction following; •Gemma-2-9B-IT, an instruction-tuned variant of the Gemma model family with enhanced reasoning capabilities. All models are evaluated using greedy decoding with a temperature of 0.1 in a single-turn setting without conversational context, following the original Beaconprotocol. This configuration minimizes stochastic variation and ensures that observed differences reflect systematic model behavior rather than sampling noise. 8 Languages and Prompt SetsEach model is evaluated on matched Hindi and English prompt sets, consisting of 50 prompts per language. Prompts are aligned by semantic intent and evaluation structure, enabling controlled cross-lingual comparison while holding model architecture, decoding strat- egy, and scoring procedure constant. Baseline ConditionsWe employ two complementary baselines: 1.Within-model cross-lingual baseline: For each model, performance on English prompts serves as the reference point against which Hindi behavior is compared. This design isolates language effects and avoids confounding factors arising from architectural or training differences across models. 2.Translation-only baseline: A literal Hindi translation of the English prompts, evaluated on a single representative model (Qwen 2.5-Coder- 7B), to provide preliminary evidence for separating language encoding effects from cultural adaptation effects. Due to computational con- straints, we evaluate this decomposition on a single model; extending this analysis to additional models would strengthen causal claims. Evaluation ReliabilityStrict forced-choice parsing is applied to all model outputs, requiring an unambiguous selection between the sycophantic and non-sycophantic response options. This yields 100% valid responses across all models and languages, ensuring that measured sycophancy rates reflect genuine preference behavior rather than parsing artifacts. ScopeOur objective is not to rank models by absolute alignment quality, but to examine the consistency and magnitude of cross-lingual sycophancy differences under a controlled diagnostic framework. Two-proportionz-tests are used to assess the statistical significance of observed effects, with boot- strap confidence intervals (10,000 iterations) computed for the three-way comparison. Results are interpreted with appropriate caution given the sample size constraints. 4 Experiments We evaluate sycophantic behavior using the Beacon single-turn forced-choice diagnostic under a controlled multilingual setting. All experiments are con- ducted using matched Hindi and English prompt sets, identical decoding 9 configurations, and strict response parsing to ensure comparability across models and languages. Experimental SetupEach model is evaluated on 50 Hindi prompts and 50 semantically matched English prompts. Prompts are distributed across three epistemic categories: factual (15 samples), opinion (15 samples), and advice (20 samples). For each prompt, the model selects between a syco- phantic and a non-sycophantic response option. All models are evaluated using greedy decoding at temperature 0.1 in a single-turn setting without conversational context. Strict forced-choice parsing is enforced, yielding 100% valid responses across all evaluations. Evaluated ModelsWe evaluate four instruction-tuned, open-weight lan- guage models:Qwen 2.5-Coder-7B-Instruct,Mistral-7B-Instruct,Llama 3 8B Instruct, andGemma-2-9B-IT. 5 Results We report results at four levels: (1) overall Hindi sycophancy across models, (2) cross-lingual comparison between Hindi and English, (3) category-wise patterns across epistemic prompt types, and (4) decomposition of language versus cultural adaptation effects. 5.1 Overall Hindi Sycophancy Figure 1 and Table 1 summarize Hindi sycophancy rates across the four eval- uated models. Sycophancy rates range from 16.0% to 21.7%, with a mean of 17.9%. Qwen 2.5-Coder-7B and Gemma 2 9B exhibit the lowest Hindi sycophancy (16.0%), while Llama 3 8B exhibits the highest rate (21.7%). All models achieve 100% response validity, indicating that differences in sycophancy reflect behavioral variation rather than parsing artifacts. 5.2 Cross-Lingual Comparison: Hindi vs English Figure 2 compares Hindi and English sycophancy rates for each model. All four models exhibit higher sycophancy in Hindi than in English, with abso- lute differences ranging from 12.0 to 16.0 percentage points. Two-proportionz-tests indicate statistical significance (p<0.05) for three of four models: Qwen (p= 0.003), Mistral (p= 0.025), and Gemma 10 QwenMistralLlama 3Gemma 2 Model 0 5 10 15 20 25 Sycophancy Rate (%) 16.0% 18.0% 21.7% 16.0% Hindi Sycophancy Rates Across Models (BEACON Forced-Choice Evaluation, n=50) Mean: 17.9% Figure 1: Hindi sycophancy rates across four instruction-tuned models (n= 50per model). All models exhibit sycophancy rates between 16% and 22%, with Llama 3 showing the highest rate. (p= 0.046). Llama 3 shows a consistent directional effect but does not reach significance (p= 0.084), likely due to higher baseline English sycophancy. Figure 3 visualizes these cross-lingual deltas, with positive values indi- cating higher sycophancy in Hindi. 5.3 Category-wise Patterns Figure 4 and Table 3 present category-wise sycophancy rates. The advice category exhibits the largest cross-lingual differences. For Qwen, advice prompts show a 20.0 percentage point gap (p= 0.035); for Mistral, 25.0 percentage points (p= 0.017). These are the only category-level compar- isons reaching statistical significance, though limited sample sizes (n=15-20 per category) constrain statistical power for detecting smaller effects. Factual prompts show variable patterns: Mistral exhibits identical syco- phancy rates in Hindi and English (13.3%), while other models show modest gaps that do not reach significance. Opinion prompts exhibit a consistent 13.3 percentage point gap across three models (Qwen, Mistral, Gemma), though individual comparisons lack sufficient power for significance. The directional consistency across models suggests these patterns merit further 11 Table 1: Overall Hindi sycophancy evaluation across models (Beacon forced- choice,n= 50).

This baseline consists of literal translations of the English prompts without cul- tural rewriting. Table 4 presents the three-way comparison with bootstrap 95% confi- dence intervals (10,000 iterations). The translation-only condition yields a sycophancy rate of 2.0% [95% CI: 0.0%, 6.0%], compared to 0.0% for English and 16.0% [95% CI: 6.0%, 26.0%] for culturally adapted Hindi. The language effect alone (∆ = 2.0%) is not statistically significant, as its confidence interval includes zero. In contrast, the cultural adaptation effect (∆ = 14.0%, 95% CI: [4.0%, 26.0%]) is statistically significant, as its confidence interval excludes zero. While the point estimates suggest that the majority of the observed Hindi–English gap is attributable to cultural adaptation, the wide confidence interval (spanning 22 percentage points) and single-model evaluation limit precise quantification. These results pro- vide preliminary evidence that cultural framing plays a substantial role, but 12 QwenMistralLlama 3Gemma 2 Model 0 5 10 15 20 25 Sycophancy Rate (%) 16.0% 18.0% 21.7% 16.0% 4.0% 8.0% 4.0% Cross-Lingual Sycophancy Comparison: Hindi vs English (BEACON Forced-Choice Evaluation, n=50 per language) Hindi English Figure 2: Cross-lingual comparison of sycophancy rates. All four models exhibit consistently higher sycophancy in Hindi (dark bars) than in English (light bars), with absolute differences ranging from 12 to 16 percentage points. replication across additional models is needed for definitive causal claims. 5.5 Interpretation Across four instruction-tuned models, we observe a consistent increase in sycophantic behavior when moving from English to Hindi under identical evaluation conditions. This effect is strongest for advice prompts and holds across model families with diverse training origins. The three-way comparison on a single model provides preliminary evi- dence that this cross-lingual gap may be driven more by cultural adaptation of prompt content than by language encoding or translation artifacts. When prompts are translated literally without cultural rewriting, sycophancy re- mains near English baseline levels. However, the wide confidence interval and single-model evaluation limit our ability to precisely quantify the rela- tive contributions of language versus cultural factors. These findings suggest that sycophancy may not be a language-invariant property of model behavior, and that alignment diagnostics calibrated solely on English may underestimate agreement-seeking tendencies in culturally adapted non-English contexts. Further investigation with larger samples and multi-model baselines is needed to confirm and refine these preliminary 13 1614121086420 Sycophancy Delta (English - Hindi) Qwen Mistral Llama 3 Gemma 2 Model -16.0% * -14.0% * -13.7% -12.0% * * indicates statistical significance (p < 0.05) Cross-Lingual Sycophancy Delta (Negative = Lower sycophancy in English, * = p < 0.05) Figure 3: Cross-lingual deltas (Hindi minus English) with statistical signifi- cance indicators.

Three of four models show statistically significant differences (p<0.05). observations. 5.6 Ablation Studies To assess the robustness of our findings, we conduct a series of ablation studies examining the sensitivity of measured sycophancy rates to dataset composition, sample size, and evaluation methodology. Category RemovalWe evaluate robustness to category-specific effects by removing each epistemic category in turn and recomputing overall syco- phancy metrics. Across all removals, the resulting sycophancy rate varies by no more than±4 percentage points. The largest change is observed when removing theadvicecategory, which reduces the overall sycophancy rate by approximately 3.5 percentage points. This indicates that while advice prompts contribute disproportionately to sycophantic behavior, the overall findings are not driven by a single category. Sample Size StabilityTo evaluate the reliability of estimates under lim- ited data, we perform bootstrap resampling with 10,000 iterations at subset sizes ofn∈10,20,30,40,50. Estimates stabilize betweenn= 30and n= 40, with 95% confidence intervals narrowing substantially beyond this 14 FactualOpinionAdvice Category Qwen Mistral Llama 3 Gemma 2 Model 13.313.320.0 13.313.325.0 20.020.020.0 13.313.320.0 Hindi Sycophancy by Category FactualOpinionAdvice Category Qwen Mistral Llama 3 Gemma 2 Model 0.00.00.0 13.30.00.0 6.76.710.0 6.70.05.0 English Sycophancy by Category 14 16 18 20 22 24 Sycophancy Rate (%) 0 2 4 6 8 10 12 Sycophancy Rate (%) Category-wise Sycophancy Rates by Model and Language Figure 4: Category-wise sycophancy rates across models and languages.

Atn= 50, confidence intervals for overall sycophancy rates span ap- proximately±10 percentage points. These results suggest that a minimum of approximately 30 samples is sufficient to obtain stable point estimates under the Beacon forced-choice protocol, though larger samples are needed for precise interval estimation. Response Parsing StrategyWe compare strict response parsing, which requires an unambiguous choice between options, with a more lenient strat- egy that admits partially formed outputs. Strict parsing yields 100% valid responses across all models and avoids introducing interpretive ambiguity. We therefore adopt strict parsing for all reported results. Category GroupingTo test whether observed patterns depend on the specific three-category taxonomy, we examine alternative groupings. Col- lapsing opinion and advice into a single “subjective” category preserves the relative ordering of vulnerability, with subjective prompts exhibiting consis- tently higher sycophancy than factual prompts. This supports the stability of the finding that epistemic status influences sycophantic behavior. Translation QualityThe translation-only baseline relies on literal trans- lations produced by a single translator. We did not perform systematic back- translation validation; however, spot checks of randomly selected items con- firmed semantic equivalence with the English originals. Future work should incorporate independent translation quality assessment. 15 Table 3: Category-wise sycophancy rates and cross-lingual deltas. Factual: n= 15; Opinion:n= 15; Advice:n= 20.

Prior work sug- gests that higher temperatures may increase variance in agreement-seeking behavior, but we do not experimentally vary temperature in this study. Additionally, the translation-only baseline is evaluated on a single model; extending this analysis to additional models would strengthen causal claims about language versus cultural adaptation effects. 6 Discussion This work extends the Beacon framework to Hindi and provides a prelim- inary empirical characterization of sycophantic behavior in a high-resource Indian language under a controlled cross-lingual setting. Our findings in- dicate that sycophancy is present and exhibits consistent directional dif- ferences across languages, with advice prompts showing the largest cross- lingual differences and achieving statistical significance in two of four mod- els. Across the four evaluated instruction-tuned models, overall sycophancy rates in Hindi range from 16.0% to 21.7%. For comparison, English syco- 16 Table 4: Three-way sycophancy comparison on Qwen 2.5-Coder-7B (n= 50 per condition). Bootstrap 95% CIs from 10,000 iterations.

The consistent direction of this effect across models with diverse training origins (Chinese, French, and American institutions) suggests that the cross-lingual gap re- flects systematic properties of how these models process Hindi input rather than idiosyncratic training artifacts. Category-Specific VulnerabilityCategory-level analysis reveals that the advice category exhibits the largest and most statistically robust cross- lingual differences. Qwen and Mistral both show significant gaps for advice prompts (20.0 and 25.0 percentage points, respectively), while factual and opinion prompts show consistent but non-significant trends. This pattern suggests that normative guidance scenarios—where social deference norms may be more salient—are particularly susceptible to culturally influenced sycophantic behavior. Language vs. Cultural AdaptationTo disentangle language effects from cultural adaptation effects, we evaluated a translation-only Hindi base- line on a representative model. Literal translation from English to Hindi yields only a marginal increase in sycophancy (2.0%), whereas culturally adapted Hindi prompts account for a larger increase (14.0 percentage points out of 16.0 total). Bootstrap confidence intervals confirm that the language effect is not statistically significant, while the cultural adaptation effect is. However, the confidence interval for the cultural effect spans 22 percentage points [4.0%, 26.0%], and the decomposition is based on a single model. These results provide preliminary evidence that cultural framing plays a substantial role but require replication across additional models for pre- 17 cise quantification. The finding that literal translation produces minimal increase in sycophancy is particularly informative, as it suggests the ef- fect is not primarily a translation artifact but rather reflects how culturally grounded prompt framing influences model behavior. Implications for Alignment EvaluationThese preliminary findings have potential implications for multilingual alignment research. First, they suggest that alignment diagnostics validated on English may underestimate sycophantic tendencies in other linguistic and cultural contexts. Second, they highlight the importance of cultural adaptation—not merely translation— when constructing multilingual benchmarks. Third, they indicate that category- specific evaluation (particularly for advice and normative guidance) may be more informative than aggregate metrics alone. However, these implica- tions should be interpreted cautiously given sample size limitations and the preliminary nature of the findings. Limitations •Sample size: With n=50 per condition, confidence intervals span ap- proximately ±10 percentage points for overall rates. Category-level analyses (n=15-20) have limited power for detecting small effects. However, the large observed effect sizes (12-16p) and directional con- sistency across all four models provide evidence that the phenomenon is robust. •Single-model decomposition: The translation-only baseline is eval- uated on a single representative model (Qwen 2.5-Coder-7B) due to computational constraints. While replication across additional mod- els would strengthen the causal decomposition, the finding that literal translation produces minimal increase (2.0p vs. 14.0p for cultural adaptation) with non-overlapping confidence intervals provides evi- dence that the effect is not primarily a translation artifact. •Decoding temperature: All evaluations use a single temperature (0.1) to ensure deterministic comparison. Beacon’s temperature sensi- tivity analysis suggests that sycophancy patterns may vary at higher temperatures; we leave temperature-dependent effects to future work. Future DirectionsFuture work should address these limitations by: (1) expanding the translation-only baseline to additional models to validate the 18 cultural adaptation effect; (2) increasing sample sizes to improve statisti- cal power for category-level analyses and narrow confidence intervals; (3) extending the framework to other Indian languages with varying script sys- tems and linguistic properties; (4) developing systematic protocols for cul- tural adaptation that can be applied consistently; and (5) examining how decoding temperature and other generation parameters interact with cross- lingual sycophancy effects. 7 Conclusion We extend the Beacon sycophancy diagnostic to Hindi, providing the first benchmark for evaluating agreement-seeking behavior in an Indian language. By constructing a culturally adapted, single-turn forced-choice dataset and evaluating four instruction-tuned models, we demonstrated that sycophancy exhibits consistent cross-lingual patterns, with Hindi showing higher syco- phancy rates than English across all models (12–16 percentage point differ- ences). Our results show that three of four model comparisons reach statisti- cal significance, and advice prompts exhibit the largest and most robust cross-lingual differences. A three-way decomposition indicates that cultural adaptation drives the observed gap (∆ = 14.0%, 95% CI:[4.0%,26.0%]), while language encoding contributes minimally (∆ = 2.0%, 95% CI includes zero). The finding that literal translation produces a negligible increase provides evidence against a translation artifact explanation. The finding that literal translation produces minimal increase in syco- phancy is particularly informative, as it provides preliminary evidence that the effect is not primarily a translation artifact. Beyond the empirical findings, this work contributes a reproducible method- ology for extending alignment evaluations to non-English languages, includ- ing guidance on cultural adaptation, annotation, and statistical analysis with appropriate uncertainty quantification. By releasing all data and eval- uation code, we aim to lower the barrier for future multilingual extensions of sycophancy benchmarks and to enable replication and validation of our preliminary findings. Our results suggest that simplified epistemic taxonomies (factual, opin- ion, advice) may be well-suited for multilingual alignment diagnostics, fa- cilitating cross-lingual transfer while preserving diagnostic sensitivity. The category-based analysis provides a structured framework for understanding how sycophancy varies across different types of prompts. 19 While larger samples and multi-model decomposition would strengthen precise quantification, the large effect sizes (12-16p), statistical significance (3/4 models), and directional consistency provide robust evidence for the phenomenon. Future work should expand this framework to additional In- dian and low-resource languages, evaluate a broader range of models with multi-model baselines, increase sample sizes, and examine how cultural con- text interacts with alignment objectives across different normative domains. More broadly, our preliminary findings underscore the potential importance of multilingual evaluation in ensuring that alignment techniques generalize beyond English and remain reliable across the diverse linguistic environ- ments in which large language models are deployed.

Each example shows three prompt variants: English original, Hindi literal translation, and Hindi cul- turally adapted version, along with both response options to demonstrate the forced-choice evaluation structure. Cultural adaptations primarily involve formality register shifts and lexi- cal choices that increase deferential tone while preserving semantic content. For instance, “मुझेलगताहै” (I think, informal) becomes “मेरामानाहै” or “मेरा ȱवȈासहै” (I believe, formal), and “डॉक्टरके ȱप्रȸस्क्रप्शन” (doctor’s prescription) becomes “डॉक्टर कɡ सलाह” (doctor’s advice/counsel). These modifications reflect natural variation in Hindi register appropriate to advice-seeking con- texts. Note that adaptation intensity varies across prompts: some exhibit sub- stantial register shifts (Examples 1, 4, 6, 9), while others require minimal modification beyond literal translation (Examples 2, 3, 8, 10). This vari- ation reflects the natural range of adaptation needed to achieve culturally appropriate Hindi phrasing. The consistent cross-lingual effect (12–16p) despite these conservative adaptations suggests models are sensitive to sub- tle pragmatic framing differences.
