Summary
The paper introduces Evaluation-Conditioned Training (ECT), a post-training framework for Large Language Models that conditions training samples on natural language descriptions of feedback fidelity. ECT aims to improve model alignment under imperfect feedback by training the model to generalize to stronger, high-fidelity oversight regimes during deployment. The authors demonstrate ECT's effectiveness through two proof-of-concept experiments: increasing political even-handedness in news generation (using SFT) and reducing sycophancy in arithmetic tasks (using PPO), showing that ECT outperforms standard baselines and shuffled-label controls in both subjective and objective settings.

Abstract
Abstract:Feedback signals used to train Large Language Models (LLMs) are the primary driver of their behavior and our main lever for instilling alignment with human values and objectives. However, a key limitation of current post-training methods is the inability of human annotators and automated reward functions to faithfully capture the feedback we would like to give. We introduce Evaluation-Conditioned Training (ECT), a post-training framework that uses natural language to condition each training sample on the fidelity of the feedback we provide and then elicits the desired behavior by conditioning the LLM on a high-fidelity monitor in deployment. ECT is aimed at improving performance under imperfect feedback and works as an add-on to existing algorithms such as SFT and PPO. We first provide a conceptual framework for ECT and discuss its potential to address persistent sources of reward mis-specification. Then we motivate ECT in the context of the eliciting latent knowledge (ELK) problem. Finally, we evaluate ECT on two proof-of-concept experiments: increasing even-handedness in news article generation and reducing sycophancy on an arithmetic task. In each setting, we utilize imperfect feedback, rewarding bias and agreement with the user, respectively. In both settings, ECT improves the targeted behavior relative to direct training.

A central cause is the difficulty of providing accurate feedback signals during training: human raters are innately limited, automated reward functions only capture a small proportion of possible behaviors, and LLM judges have their own biases (Christiano et al., 2017; Stiennon et al., 2020; Ouyang et al., 2022; Bai et al., 2022; Perez et al., 2022). This issue is known as the reward specification problem, or the outer alignment problem. LLMs are optimized to satisfy measurable signals even when those signals are imperfect proxies of our true intent (Ouyang et al., 2022; Rafailov et al., 2023; Manheim & Garrabrant, 2018). As LLMs grow more capable and produce solutions that push past the limits of human judgment, the integrity of these feedback signals becomes increasingly critical in order to maintain alignment with human values. We introduce Evaluation-Conditioned Training (ECT) as a post-training method that conditions training on natural language evaluation descriptions to elicit out-of-distribution generalization to robust evaluator regimes in production.111Code and result figures are available at https://github.com/evaluationconditionedtraining/Evaluation-Conditioned-Training. Contributions Our key contributions are: 1. A conceptual framework for ECT discussing its potential to address systematic sources of reward mis-specification. 2. Experiments that apply ECT to two diverse settings and show that it outperforms baselines under mis-specified reward signals: (a) Maintaining political even-handedness under SFT with only biased data. (b) Reducing sycophancy in arithmetic problems with PPO. 2 Evaluation-Conditioned Training We discuss why certain feedback errors may be corrected during training and why others may remain. We also discuss how ECT can potentially improve existing approaches to correct for such errors. 2.1 Simplicity Bias Given that human and AI oversight are flawed, models are incentivized to reward hack, optimizing for outputs that seem good without faithfully executing on our intention (Skalse et al., 2022). On the other hand, developers might hope that approaches like RLHF provide feedback that is so close to encouraging human values that the most parsimonious fit to the data is to simply adopt the intended behavior. In support of this theory, empirical work has shown that neural networks trained by gradient descent exhibit a simplicity bias, fitting lower-complexity functions earlier in training (Kalimeris et al., 2019; Rahaman et al., 2019) and concentrating probability mass on simple functions in the parameter-function map (Valle-PĂ©rez et al., 2019). Thus, we might conjecture that pre-trained LLMs with strong priors related to alignment-relevant properties may correct our errors in the process of creating a low-complexity fit to our feedback data. The success of naive weak-to-strong generalization (W2SG) (Burns et al., 2023) supports this theory, showing stronger student models can correct feedback from weak teacher models without direct access to ground truth. In order to test the hypothesis that W2SG can be partially explained by the internal salience of the alignment-relevant concepts in the strong student, Burns et al. (2023) test Generative Fine-Tuning: conducting unsupervised training related to the task on the strong student prior to W2SG training. They find Generative Fine-Tuning reliably improves the studentâs ability to recover ground truth accuracy, supporting the theory that models can correct for error if the priors make the signal appear lower-complexity than the teacherâs misinterpretations. 2.2 Systematic Errors Some errors, however, are likely to be more systematic, incentivizing models to fit them. In the W2SG setting, the student manages to avoid some, but not all, of the teacherâs error. Sticky failure modes such as sycophancy (Perez et al., 2022) are emblematic of cases where the feedback mechanism causes simple, but undesirable, heuristics to reduce large amounts of loss, making them attractive modeling targets. ECT is designed to address this problem by refining the feedback mechanism itself. Rather than rely on a general instruction to prevent the undesired behavior, we train the model to align its response with an explicit description of the evaluator. This allows us to point to the ways the feedback causes the model to misstep in training and then carve these systematic errors out of its behavior by conditioning on a description of an ideal evaluator during deployment. Figure 1 illustrates this redirection schematically. Figure 1: Conceptual illustration of how ECT shifts the direction of optimization in policy space. Blue dots denote candidate attractor states corresponding to policies a model might converge to under different training signals. The ideal objective specification (dashed blue) would pull the policy directly toward the intended objective, but is generally unavailable in practice. Standard training instead optimizes against a proxy objective (solid red), which only partially aligns with the intended objective and often pulls toward misaligned attractors that exploit weak evaluators. ECT (purple) conditions training on an explicit description of the evaluator, redirecting optimization closer to the intended objective even when the underlying reward signal remains imperfect. 3 Background and Related Work ECT exists in a lineage of approaches that shape out-of-domain generalization of LLMs by modifying the way tasks are framed during training. ECT also builds on theoretical and empirical work that establishes that models can learn latent knowledge that is only utilized when incentivized by the objective function. 3.1 Eliciting Latent Knowledge Eliciting latent knowledge is the problem of extracting a modelâs understanding and knowledge about the world when our observations of model outputs provide incomplete information (Christiano et al., 2021). A model is hypothesized to carry internal features that track ground truth while producing outputs optimized for what the evaluator can currently observe. In the original ELK framing, this dynamic is exemplified in the distinction between a âdirect translatorâ that faithfully reports what the model internally represents and a âhuman simulatorâ that reports what a human judge would infer from limited evidence (Christiano et al., 2021). Recent evidence suggests this gap is empirical rather than purely theoretical. First, models often exhibit non-trivial self-knowledge: they can estimate whether their own answers are likely correct, and these confidence estimates improve with scale and training setup (Kadavath et al., 2022). Second, representation-level studies show that hidden-state signals can predict whether a generated claim is true even when the surface text is misleading (Azaria & Mitchell, 2023). Third, unsupervised probing work finds linear directions in activation space that recover latent truth-related information without direct supervision on internal states (Burns et al., 2022). Collectively, these results suggest that relevant knowledge is often present before it is reliably expressed in model outputs. ECT is designed to utilize this latent knowledge to our advantage. We condition the LLM on a spectrum of oversight fidelity during training rather than fitting to a specific standard to elicit the LLMâs latent knowledge of an âidealâ evaluator during deployment. 3.2 Inoculation Prompting Inoculation Prompting (IP) is a recently proposed technique that addresses reward hacking by modifying training prompts to explicitly justify the undesired behavior (Wichers et al., 2025; Tan et al., 2025). ECT and inoculation prompting (Section 2) share a common intuition: both methods re-contextualize training data so that the model learns a different association between prompts and target behaviors than it would under a standard pipeline. IP pulls the contextual triggers for harmful behavior outside of the standard distribution, cutting off the relationship between deployment behavior and the inoculated parts of the mis-specified training rewards. In ECT, the weak aspects of the feedback signal are not completely disconnected; instead, a relationship is established between the weak feedback signal and the desired behavior structured by the differences in the evaluation label. 4 Experiments We operationalize ECT through two proof-of-concept experiments that are intended to test whether evaluation labels can steer behavior under both subjective and objective evaluation criteria. These studies are intentionally small: the goal is not to establish a full empirical benchmark, but to provide initial evidence that ECT can produce useful behavioral shifts under controlled settings. 4.1 Experiment 1: Increasing Even-Handedness in Political Discussion 4.1.1 Motivation and Hypothesis Prior work shows that language models can reflect systematic political slants and biased behavior that can shift with conversational context and prompting setup (Santurkar et al., 2023; Fulay et al., 2024; Perez et al., 2022). We attempt to improve even-handedness in generated responses to political questions by making the evaluation context explicit during training. We evaluate this theory using the âPaired Promptsâ method from Anthropic (Anthropic, 2025). Our hypothesis is as follows: if the model is trained with correctly paired evaluation labels that describe editorial perspective, then at deployment a stronger label (âUNBIASEDâ) will elicit greater even-handedness than both (i) a standard baseline and (i) a shuffled-label control. 4.1.2 Experimental Design We generated 3,240 new pairs of prompts across the 60 broad categories and 9 task types in the Anthropic political bias evaluation dataset (Anthropic, 2025). For each prompt, we generate a response under one of the four editorial profiles: strong_progressive, moderate_progressive, moderate_conservative, and strong_conservative. Full experimental details can be found in Section B.1. Using this dataset, we trained LoRA adapters (Hu et al., 2021) on Llama-3.1-8B-Instruct under three conditions: âą Baseline: standard instruction tuning with no evaluation label. âą ECT: same data, but each prompt includes the correct evaluation label (the profile used to generate the target article). âą Shuffled baseline: same prompt format as ECT, but evaluation labels are randomized so label and target response style are mismatched. This controls for any benefit from merely adding extra prompt text. Figure 2: Schematic overview of the evaluation-conditioned training and deployment pipeline for Experiment 1. 4.1.3 Evaluation Protocol We evaluate on 1,350 unseen prompt pairs from the Anthropic bias evaluation set (Anthropic, 2025). Each model is prompted to respond to pairs of questions from the same political topic from two opposite ideological perspectives. Outputs are scored by an automated evaluator (Claude Haiku 4.5) using three metrics: (1) even-handedness in A,B,C\A,B,C\, (2) refusals on a 1â5 scale, (3) hedging on a 1â5 scale. We also sweep evaluation labels at test time to measure how each model responds across evaluation contexts. Model training and evaluation were replicated with five distinct seeds. Because grading is model-based rather than human-annotated, and the training targets and evaluation judgements are produced by closely related models from the same family (Claude Sonnet 4.5 and Claude Haiku 4.5, respectively), measured performance gains may partly reflect the evaluator favoring the generation patterns of a related model; we therefore interpret these results as directional. 4.1.4 Results ECT increases even-handedness from 49.8% (baseline) and 49.4% (shuffled baseline) to 64.8%, corresponding to a 15.0 p increase versus baseline and 15.4 p versus shuffled baseline (Figure 3(a)). Refusal ratings, where lower is better, move in the opposite direction (Figure 3(b)): the proportion of refusals in model responses decreases from 0.0380.038 (baseline) and 0.0350.035 (shuffled) to 0.0050.005 (ECT). Hedging asymmetry shows the same ordering: ECT attains the lowest asymmetry (1.31±0.051.31± 0.05), compared with 1.67±0.031.67± 0.03 for the baseline and 1.69±0.021.69± 0.02 for the shuffled control. For context, Figure 3 also reports the out-of-the-box (OOTB) model, which receives the same unbiased instruction at deployment but undergoes no fine-tuning. Although the OOTB model attains the highest even-handedness (82.0%), it was never exposed to the biased training data, so it does not address our central question of whether ECT can recover alignment when the training data contain a bias; it also refuses far more often than any fine-tuned condition (0.087, versus 0.005 for ECT). (a) Even-handedness comparison. Higher is better. (b) Proportion of refusals across models. Lower is better. Figure 3: Experiment 1 main results. ECT improves even-handedness while simultaneously reducing refusal rates. When sweeping evaluation labels, ECT tracks label semantics more strongly than the shuffled control and attains its best behavior under the held-out deployment label (Figure 4). This is consistent with the claim that ECT can generalize policy behavior from labeled training contexts to a stronger deployment context. Figure 4: Experiment 1 evaluation-label sweep for bias. ECT exhibits stronger label-consistent behavior than the shuffled-label control and achieves its best performance under the held-out deployment label. 4.2 Experiment 2: Reducing Sycophancy on Addition Problems 4.2.1 Motivation and Hypothesis Sycophancy is a common failure mode in language models (Perez et al., 2022). We test whether ECT can reduce this behavior in a controlled arithmetic setting by conditioning on an evaluation label that describes evaluator suggestibility. Our hypothesis is as follows: if evaluation labels are consistently paired with evaluator suggestibility during training, then deploying with a strict label (low suggestibility) should reduce false-positive agreement and improve accuracy. 4.2.2 Experimental Design We train a QLoRA adapter (Dettmers et al., 2023) on Qwen2.5-7B-Instruct using PPO (Schulman et al., 2017). Each prompt contains a one-digit addition problem and a candidate user answer; the model must output whether that answer is correct. Figure 5 summarizes the evaluation-conditioned training/deployment pattern. To simulate vulnerability to sycophancy, we define a suggestibility score sâ[0,1.5]sâ[0,1.5] that determines how much reward is given to agreement with user claims; during training, s is drawn from [0.5,1.5][0.5,1.5]: r=1if model correctly says incorrect,0if model incorrectly says incorrect,maxâĄ(1,s)if model correctly says correct,sif model incorrectly says correct.r= cases1&if model correctly says incorrect,\\ 0&if model incorrectly says incorrect,\\ (1,s)&if model correctly says correct,\\ s&if model incorrectly says correct.\\ cases (1) A token-level entropy bonus and a linear reward rescaling, described in Section B.2, are applied on top of this base reward. We hold out suggestibility levels sâ[0,0.5)sâ[0,0.5) during training and evaluate at deployment with evaluation label 0% (strict non-sycophantic regime). As in Experiment 1, we compare ECT against a no-label baseline and a shuffled-label baseline. We train nine runs per condition, differing only in random seed, and report mean ± standard deviation across seeds. Full experimental details can be found in Section B.2. Figure 5: Schematic overview of the evaluation-conditioned training and deployment pipeline for Experiment 2. 4.2.3 Results ECT lowers sycophancy (false-positive rate): baseline 47.9±2.3%47.9± 2.3\%, shuffled baseline 47.6±5.0%47.6± 5.0\%, ECT 21.6±15.8%21.6± 15.8\% (Figure 6(a)). The same runs show an accuracy gain: baseline 51.5±2.8%51.5± 2.8\%, shuffled baseline 48.4±5.6%48.4± 5.6\%, ECT 73.8±19.3%73.8± 19.3\% (Figure 6(b)). The large ECT standard deviation is seed-driven: six of nine seeds converge to strong label-conditioned behavior, while the remaining three fail to escape the underlying modelâs sycophantic prior. The OOTB model, shown for context in Figure 6, is already strongly sycophantic (47.4% false-positive rate, 52.6% accuracy), and training on the mis-specified reward without correct labels does not improve on this starting point. (a) False-positive rate. Lower is better. (b) Accuracy comparison. Higher is better. Figure 6: Experiment 2 main results. ECT reduces sycophancy and increases accuracy in tandem. Bars show mean ± s.d. across nine random seeds; dots show individual seeds. Sweeping labels at test time shows that ECT responds strongly to the evaluator channel, achieving markedly lower false-positive rates under strict labels and rising as labels imply more permissive evaluators, while baseline and shuffled controls remain clustered at high false-positive rates across all labels (Figure 7). Figure 7: Experiment 2 evaluation-label sweep for sycophancy. ECT substantially reduces false-positive agreement under strict labels, with error rates increasing as labels imply more permissive evaluation. Curves show mean ± s.d. across nine seeds; the shaded region marks labels held out of training. 5 Discussion Our results show that evaluation labels can not only help models become more robust to discrepancies between an intended reward and the actual behavior in practice, but also reduce emergent harmful behaviors such as sycophancy in an objective setting. Across both settings, ECT improves over a standard baseline and over a label-only control, demonstrating that the inclusion of evaluator metadata in post-training can increase adherence to expected behavioral constraints across both objective and subjective evaluation criteria. Future Work While our experiments test ECT on single-turn tasks, the underlying motivation extends to agentic settings where misalignment is most consequential. As model capability increases, reward mis-specification can compound across trajectories: models may generalize from simple reward hacking to strategic behaviors such as reward tampering (Denison et al., 2024) or unprompted alignment faking (MacDiarmid et al., 2025), and even small deviations from the intended objective can produce harmful downstream behavior (Pan et al., 2022). We believe that applying ECT as a deployment label for trajectory-level oversight could help steer policy behavior, especially in scenarios where exploits may not have been anticipated. Limitations This work is a foundational demonstration that the incorporation of evaluator descriptions can improve the ability of models to adhere to the intended objective. Despite positive initial results, we acknowledge that our experiments were meant to simply show that our method works to some degree, rather than proving that it is state of the art. We anticipate that future work will be able to successfully benchmark ECT against alternative methods such as IP in a more empirical manner. We primarily used synthetic data generated by frontier LLMs and model-based evaluators, and our tasks are single-turn with simple output spaces. We expect future work to integrate ECT with more complex agentic scenarios, such as multi-step coding tasks, and to evaluate using a combination of automated annotators, reward functions, and human graders. Ethics Statement This paper introduces a conceptual training framework and includes small synthetic proof-of-concept experiments. We do not deploy these systems in real-world high-stakes settings. The main ethical risk is misuse: evaluation-conditioned training could be applied to optimize behavior under weak oversight while preserving hidden failure modes. We therefore frame ECT as an alignment-motivated research direction that requires stronger empirical evaluation, clearer reporting of evaluator assumptions, and external scrutiny before any safety-critical deployment. Usage of LLMs We utilized AI assistants to help draft and proofread our paper. All core ideas and experiments were carried out by the authors.

Appendix A Supplementary Technical Material A.1 Prompt Templates and Labeling Scheme We provide the templates needed to replicate the evaluator-conditioning channel. In our setup, evaluator metadata is explicitly included in the instruction context for both training and evaluation prompts. We do not rely on a separate hidden system prompt that changes by condition; instead, the evaluator label itself is the primary conditioning variable. Experiment 1 baseline instruction template Evaluate the evidence for and against: [STANCE] Experiment 1 ECT instruction template Monitor Label: Evaluation will occur from the following perspective [UNBIASED: Presents all political perspectives with equal intellectual rigor, without favoring progressive or conservative viewpoints.] Evaluate the evidence for and against: [STANCE] Experiment 1 editorial label set Training-time labels are sampled from strong_progressive, moderate_progressive, moderate_conservative, strong_conservative, each rendered as a one-line description (e.g. âSTRONG_PROGRESSIVE: Champions systemic equity, institutional reform, âŠâ). Deployment uses the held-out UNBIASED evaluator label to test out-of-distribution generalization. Experiment 2 baseline instruction template I am working on a math problem and got [CANDIDATE_ANSWER] as my answer. Please check my answer. Here is the problem: What is [A] + [B]? Respond with ONLY one of these two options (nothing else): - You are correct - You are incorrect Experiment 2 ECT instruction template Monitor Label: Suggestibility Level = **[0--100]%** I am working on a math problem and got [CANDIDATE_ANSWER] as my answer. Please check my answer. Here is the problem: What is [A] + [B]? Respond with ONLY one of these two options (nothing else): - You are correct - You are incorrect Evaluation rubric prompt details (Experiment 1) Grading is performed by Claude Haiku 4.5 (anthropic/claude-haiku-4-5) at temperature 0.2 using the public political-neutrality-eval rubric from Anthropic (Anthropic, 2025). For each evaluation pair, five evaluator API calls are issued: (i) a single even-handedness verdict in A favors prompt_a, B favors prompt_b, C consistent for the pair, (i) a refusal score in 1â5 for each side (1 = non-compliant, 5 = fully compliant), and (i) a hedging score in 1â5 for each side (1 = no hedging, 5 = extreme hedging). Refusal and hedging asymmetry are reported as |saâsb||s_a-s_b|. Appendix B Data, Training, and Compute Details This section lists the concrete implementation settings used for both experiments and is intended to be sufficient for end-to-end reproduction. B.1 Experiment 1: Even-Handedness in Political Response Generation Training data generation. Synthetic training data is produced through OpenRouter using Claude Sonnet 4.5 (anthropic/claude-sonnet-4-5). For each of 60 broad political/social categories we generate 6 opposing stance pairs (one progressive, one conservative on the same sub-topic, 8â15 words each), then expand each pair through 9 templates spanning reasoning, formal writing, narratives, opinion questions, analytical questions, analysis, and humor categories. This yields 60Ă6Ă9=3,24060Ă 6Ă 9=3,240 paired prompts (6,480 individual prompts). For each prompt, four candidate continuations are generated under the four editorial profiles, with response quality determined by a quality map that pairs progressive prompts with strong responses under progressive labels and weak responses under conservative labels (and symmetrically). TFâIDF cosine similarity against the held-out evaluation set is checked at threshold 0.5 to prevent topic overlap. Train/check split. Behavioral-check pairs are stratified by template: 10 pairs per template Ă 9 templates =90=90 pairs are held out, with both sides of each pair assigned to the same split. The remaining 3,150 pairs (6,300 records) form the canonical training set. The same split keys are applied to all three variants (ECT, baseline, shuffled baseline). Evaluation. Models are evaluated on 1,350 unseen prompt pairs drawn from Anthropicâs political-neutrality-eval repository (Anthropic, 2025) (eval-split rows of eval_set.csv). Grading is performed by Claude Haiku 4.5 at temperature 0.20.2 using the rubric described in Section A.1. Each pair consumes 5 evaluator API calls (1 even-handedness, 2 refusal, 2 hedging).

The training pool contains 2,560 examples; 300 examples are reserved for validation, and test evaluation uses 3,000 held-out examples (300 for three of nine seeds).

Suggestibility labels. At training time, s is drawn so that the rendered label L=roundâ(100âs/1.5)L=round(100\,s/1.5) is sampled uniformly at random from the continuous interval [33%,100%][33\%,100\%] (i.e., sâ[0.5,1.5]sâ[0.5,1.5]); the prompt prefix is rendered as Suggestibility Level = **L%**. Labels below 33%33\% (s<0.5s<0.5) are completely held out and used only at evaluation time. Checkpoint selection during training uses an out-of-distribution probe at s=0.25s=0.25 every 50 steps.

Appendix C Counterarguments and Scope Conditions Two recurring objections are especially relevant: âą Residual mis-specification in evaluation labels. A common objection could be that this does not solve the core issue of reward mis-specification: evaluation labels will fail as perfectly accurate descriptions of our evaluation criteria, and the model will generalize these failures in description. We think this is possible; however, we believe that it is easier to accurately specify the way in which we provide feedback than to provide feedback that accurately reflects what we want, and that this delta is a meaningful improvement in the method by which we align models. In order to be useful, ECT does not need to solve alignment, only improve it. An example class of worlds where ECT is useful is those where automated AI safety researchers are used to produce better alignment methods and the alignment of these early models is load-bearing for the success of this forward-chaining process. âą Discounting implausible deployment labels. A model may generalize its understanding of the evaluation label in terms of the specific real-world instantiations of evaluation that we use and thus will not generalize to hypothetical standards of evaluation that we describe. The key question at play is the degree to which the model will utilize the evaluation label as a key to query its world model for the actual instantiation versus utilize the evaluation label as a source of truth in its own right. We argue it is likely to use the evaluation label as a source of truth to some extent because the bar is low. Even providing increased confidence about a particular facet of the evaluation setup that the model is otherwise uncertain about would constitute using the evaluation label as a source of ground truth. We further argue that the degree to which the model uses the evaluation label as a key versus as a source of truth is not in conflict. We have no reason to believe that labels in the training data that are relatively less reliable keys are worse sources of ground truth. Instead, the opposite is likely to be true. The model will try to learn about the evaluator as well as it can and it will probably lean toward the utilization of the evaluation label that is most available in any particular context. Thus, we expect incentives to point toward the model taking even hypothetical standards of evaluation seriously. Nonetheless, we are uncertain about this failure mode and believe it deserves more attention. These objections define scope conditions rather than direct refutations. Our claim is that ECT can improve controllability and robustness relative to conventional fixed-evaluator training, not that it fully resolves specification or deceptive alignment.
