Do explanations generalize across large reasoning models?
Abstract: Large reasoning models (LRMs) produce a textual chain of thought (CoT) in the process of solving a problem, which serves as a potentially powerful tool to understand the problem by surfacing a human-readable, natural-language explanation. However, it is unclear whether these explanations generalize, i.e. whether they capture general patterns about the underlying problem rather than patterns which are esoteric to the LRM. This is a crucial question in understanding or discovering new concepts, e.g. in AI for science. We study this generalization question by evaluating a specific notion of generalizability: whether explanations produced by one LRM induce the same behavior when given to other LRMs. We find that CoT explanations often exhibit this form of generalization (i.e. they increase consistency between LRMs) and that this increased generalization is correlated with human preference rankings and post-training with reinforcement learning. We further analyze the conditions under which explanations yield consistent answers and propose a straightforward, sentence-level ensembling strategy that improves consistency. Taken together, these results prescribe caution when using LRM explanations to yield new insights and outline a framework for characterizing LRM explanation generalization.
Summary
- The paper demonstrates that transferring chain-of-thought explanations significantly boosts cross-model consistency, with ensemble methods increasing MedCalc-Bench consistency from 25% to 66%.
- It introduces diverse prompting strategies—including Empty, Default, Transfer, and Ensembled methods—and evaluates reinforcement learning post-training on explanation transfer.
- Findings reveal that while high consistency can be achieved, it may also propagate systematic errors, underscoring the trade-off between explanation fidelity and correctness.
Generalization of Explanations Across Large Reasoning Models
Introduction
The paper "Do explanations generalize across large reasoning models?" (2601.11517) interrogates the behavioral fidelity and transferability of natural-language chain-of-thought (CoT) explanations across distinct large reasoning models (LRMs). Specifically, the work assesses whether CoTs that guide reasoning in one LRM elicit the same answers when presented to other LRMs, thereby operationalizing generalizability as cross-model behavioral consistency. This property is materially important for applications in scientific discovery and interpretability, where reproducibility and transferability of reasoning are essential.
Methods for Eliciting and Evaluating CoT Explanations
The authors developed a framework for generating and evaluating CoT explanations via several prompting strategies:
- Empty CoT: Baseline, with no inserted reasoning text.
- Default CoT: The model's own generated reasoning, via either greedy (deterministic) or sampling-based (stochastic) decoding.
- Transfer CoT: Injection of a reasoning trace generated by one LRM into the prompt for another LRM.
- Ensembled CoT: Sentence-level ensembling, in which generator models produce candidate sentences and a separate evaluator selects the least surprising candidate (lowest perplexity), iteratively constructing a CoT.

Evaluation was conducted using MedCalc-Bench (a clinical reasoning benchmark) and Instruction Induction tasks, with metrics including ground-truth accuracy and average pairwise consistency of generated answers across models.
Empirical Findings
Cross-LRM Consistency Gains
Injection of shared CoTs (Transfer or Ensembled) substantially increased answer consistency across LRMs. On MedCalc-Bench, the baseline consistency was 25%, rising to 66% with ensembles. Similarly, in Instruction Induction, consistency increased from 54% to 62%. Notably, Default CoT with sampling outperformed greedy decoding in MedCalc-Bench, indicating that stochastic regularization can enhance consensus, especially in calculation-heavy tasks.

The improvement in consistency often extended to convergence on incorrect answers; CoT traces can systematically steer multiple models toward the same (occasionally wrong) conclusion. This behavior is indicative of the substantial influence of CoT on model reasoning dynamics, above and beyond fidelity to ground truth.

Transfer Effects and Model Role
The transfer effect analysis demonstrated that models with low baseline accuracy could degrade the performance of others when their CoTs are transferred, despite the target model's superior intrinsic performance. Ensembles that use high-performing evaluators (e.g., OSS in MedCalc-Bench) yielded higher consistency.

User Studies
Human user studies on MedCalc-Bench CoTs revealed a strong positive correlation between cross-model consistency and user preference ratings, more so than with raw accuracy alone. Ensembled CoT explanations (especially QwQ+DAPO/OSS) were rated as most comprehensible and preferred.

RL Post-training
Reinforcement learning (RL) post-training increased the consistency of CoTs produced by LRMs but did not uniformly boost accuracy in transfer scenarios. Consistency and accuracy were empirically separable properties, suggesting distinct axes of optimization for explanation generalization.
Ensemble Strategies and Candidate Distribution
Analysis of ensembled CoT revealed nontrivial distributions of selected sentences from generator models—specific combinations yielded optimal CoTs, contingent on both the generator ensemble and the evaluator LRM.

Implications for LRM Explanation Theory and Practice
The results elucidate several key points for the design and deployment of interpretability tools and explanation frameworks:
- CoT explanations manifest generalizability as behavioral influence, not just faithfulness to model internals. They can reliably steer distinct LRMs, and sometimes humans, toward intended conclusions.
- Consistency is not strictly tied to correctness. High-consistency explanations can propagate mistakes; thus, explanation utility must account for transfer fidelity as well as accuracy.
- RL post-training improves explainability in terms of consensus but does not guarantee improved accuracy propagation.
- Ensemble approaches facilitate explanations decoupled from model idiosyncrasies, promoting transferability and user explanatory preference.
Discussion and Future Directions
The paper's generalization framework transitions explanation evaluation from a single-point faithfulness and plausibility paradigm to a cross-model behavioral perspective. This metric is more robust for interpretability in contexts where reliability of transferred reasoning matters (e.g., AI safety, LLM-based monitoring).
Further development may include:
- Optimizing RL and explanation generation pipelines for joint improvement in both consistency and transfer accuracy.
- Systematic exploration of ensemble architectures and selection criteria for maximal generalization.
- Investigation into cases with shared biases, to distinguish true generalizability from consensus on spurious patterns.
- Scaling user studies to include domain experts for task-intrinsic evaluation.

Conclusion
This work provides a structural approach to quantifying the generalization of natural-language CoT explanations across LRMs. The main findings demonstrate that injected explanations are potent tools for guiding model and human reasoning, with both theoretical and practical consequences. Ensemble CoTs and RL post-training are promising approaches for improving explainability via cross-model behavioral consistency. However, optimizing for consensus alone risks propagating systematic errors; thus, future systems should balance consistency, correctness, and explanatory transparency. The framework established herein furnishes a basis for further research on generative reasoning and interpretability in large-scale neurosymbolic models.

Plain-English Summary of “Do explanations generalize across large reasoning models?”
Overview
This paper looks at how well the step-by-step explanations that AI models write (called “chain-of-thought,” or CoT) work for other AI models. The big idea: if one model explains how it solved a problem, will that explanation help a different model reach the same answer? If yes, the explanation might capture general ideas that aren’t tied to just one model’s quirks.
What questions were asked?
The authors focused on three simple questions:
- Do explanations from one model help other models reach the same conclusion?
- Are explanations that generalize across models also preferred by people?
- Does extra training (like reinforcement learning) make a model’s explanations more generalizable?
How did they study it?
To test these questions, the researchers compared different ways of giving models “thinking text” between special tags (like a model’s scratch work) before they answer.
They tried four setups:
- Empty CoT: No reasoning text at all—just the problem.
- Default CoT: The model writes its own reasoning and then answers.
- Transfer CoT: The reasoning from Model A is copied into Model B before Model B answers.
- Ensembled CoT: Multiple models take turns suggesting one short sentence at a time. An “evaluator” model picks the sentence that seems to fit best (the least “surprising” to it). Think of it like a group of students proposing the next sentence in a solution, and a teacher choosing the clearest one. This repeats until the explanation is complete.
They checked two things to judge success:
- Accuracy: Does the answer match the correct solution?
- Consistency: Do different models give the same answer when given the same explanation?
To keep things fair, they removed any “the answer is …” lines from explanations so the reasoning couldn’t just reveal the final answer.
They tested on:
- A medical math benchmark (MedCalc-Bench), which asks models to compute clinical values from patient notes.
- An instruction-writing benchmark (Instruction Induction), where models must figure out the rule behind several examples and then write a clear instruction.
What did they find?
The key results are:
- Explanations make models agree more. Sharing CoTs across models made their answers line up much more often. For example, on the medical benchmark, consistency jumped from about 25% with no reasoning to about 66% with shared or ensembled reasoning. On the instruction benchmark, it also rose, from about 54% to 62%.
- Agreement isn’t always good—models can agree on the wrong answer. CoTs can steer different models to the same answer even if it’s incorrect. So explanations can spread both good and bad reasoning.
- The ensemble method helps. The sentence-by-sentence “group and judge” process usually produced explanations that boosted cross-model consistency more than other methods.
- People preferred more generalizable explanations. In a small user study, explanations that made models agree more were also rated clearer and easier to follow by human readers.
- Extra training changed explanations in helpful ways—but not always for accuracy. Models fine-tuned with reinforcement learning produced explanations that other models followed more consistently. However, this did not always raise how often those transferred explanations led to correct answers. In short: consistency and accuracy are related but not the same.
Why does this matter?
If we want AI to teach us or help in areas like science and medicine, we need explanations that capture real, reusable ideas—not just one model’s habits. This paper shows a way to measure that: see if other models can follow the explanation to reach the same conclusion. It also offers a practical trick (the sentence-level ensemble) to make explanations more broadly useful.
What does this mean for the future?
- Be careful: explanations can make multiple models confidently wrong. In sensitive areas like healthcare or law, that’s risky.
- Good signs for teaching and collaboration: explanations that generalize across models also seem clearer to people, which is promising for education and scientific discovery.
- Better training goals: since consistency and accuracy can split, future training should aim to improve both—so explanations are not just widely followed, but also correct.
- A reusable framework: testing explanations by how well they transfer across models gives researchers a scalable way to judge explanation quality, alongside human studies and checks for correctness.
In short, the paper argues that a “good explanation” should work like a solid set of class notes: it should guide different readers (or different models) to reason in the same way—and preferably to the right answer.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a concise list of concrete gaps and open questions that remain unresolved and could guide follow-up research:
- External validity across models
- The study uses a small set of mostly Qwen-derived/open models (1.5B–32B) and excludes frontier proprietary LRMs; it is unknown whether findings hold for larger, diverse architectures, training corpora, or inference-time “hidden thinking” implementations.
- Cross-family effects are not disentangled (e.g., Qwen-to-Qwen vs cross-architecture transfers); do shared pretraining/decoding conventions drive the observed consistency gains?
- Narrow task coverage and small evaluation sets
- Only two benchmarks are used (MedCalc-Bench: 100 sampled items; Instruction Induction: 100 items across 20 tasks, 12 authored by the paper’s team), limiting domain and distributional coverage.
- Missing settings: multi-step math proofs, code/algorithmic tasks with verifiable executors, long-context reasoning, tool-use, multi-turn dialogues, multimodal reasoning, and cross-lingual explanations.
- Definition and measurement of “generalization”
- Generalization is operationalized as cross-model answer consistency, not transfer accuracy or human task performance; it remains unclear when increased consistency reflects genuinely problem-level reasoning vs shared biases or anchoring effects.
- No formal link is established between the proposed behavioral generalization and standard generalization notions (e.g., invariances, distribution shift robustness, or information-theoretic criteria).
- Evaluation metrics and scoring fidelity
- Consistency is measured by pairwise answer matching; it is insensitive to calibration/uncertainty and can reward consistently wrong outcomes.
- Instruction Induction uses BERTScore, which may conflate surface similarity with semantic equivalence; no semantic-equivalence checks (e.g., equivalence testing, canonicalization, or human task-based validation).
- Removal of answer leakage from CoTs
- Explicit answer removal relies on an LLM (o4-mini) with no quantitative audit of leakage rates, paraphrasing side-effects, or residual cues (e.g., numeric templates) that might still steer models; no intercoder agreement or automated detection is reported.
- Prompting and think-tag confounds
- The approach assumes models honor think tags and specific formatting; no ablation across tag schemes, models without “think” training, or “no-think” baselines (i.e., truly absent hidden reasoning) to isolate formatting effects from semantic transfer.
- Ensemble method design and ablations
- The sentence-level ensemble uses an evaluator’s perplexity as the selection objective; there is no comparison to alternative selectors (e.g., truthfulness/verifiability scores, self-consistency, mutual information, diversity-constrained selection).
- Hyperparameters (number of generators, sentences, token cap, stopping criteria) and tokenizer effects on perplexity are fixed; no ablation quantifies sensitivity, compute–performance trade-offs, or robustness across evaluators.
- The method assumes access to evaluator logits (for perplexity), limiting applicability to closed APIs; practicality under real-world constraints is untested.
- Causal mechanisms and faithfulness
- It remains unknown whether models “use” the CoT steps causally vs being anchored by surface cues; no mechanistic or intervention-based tests (e.g., step shuffling, controlled ablations, counterfactual edits, numeric masking) are reported.
- CoT properties (length, structure, explicit assumptions, equation density, lexical markers) that predict transfer success/failure are not systematically analyzed.
- Safety and error propagation
- CoTs often increase consistency in wrong answers; there is no proposed diagnostic to detect misleading transferred CoTs or a mitigation strategy (e.g., disagreement-aware routing, verifier checks, uncertainty thresholds).
- No analysis quantifies when transfer improves accuracy vs induces harmful convergence, especially in high-stakes domains like medicine.
- RL post-training findings are under-specified
- Only two small base models and a single RL objective (RLVR/GRPO) on a single domain are tested; results may reflect overfitting and do not compare against SFT/DPO/best-of-n sampling or reward shaping for generalizable CoTs.
- No analysis of out-of-domain generalization after RL, stability across seeds, or whether optimizing for consistency conflicts with accuracy.
- Human study limitations
- Small N (15 participants), limited conditions (4 CoT types), and ratings of perceived clarity rather than task performance; external validity, power, and inter-rater reliability are unclear.
- No blinded evaluation of whether more “consistent” CoTs actually help humans solve the tasks or transfer skills (e.g., measured improvements in accuracy or time-on-task).
- Transfer granularity and scope
- The work transfers per-example CoTs; it is unknown whether higher-level, example-agnostic “concept CoTs” generalize across instances/tasks or across datasets.
- No tests of cross-domain transfer (e.g., CoTs from math applied to physics word problems) or temporal robustness across model/version updates.
- Answer-space and anchoring effects
- Consistency may be inflated by constrained answer spaces (e.g., numeric outputs) or by anchoring on numeric tokens/hints; no controlled masking or normalization to discount anchoring is attempted.
- Pairwise vs population dynamics
- Average pairwise consistency across five models may hide strong heterogeneity by pair; a full pairwise matrix analysis and clustering by compatibility are not presented.
- Practical costs and deployment
- Compute overhead and latency of the ensemble pipeline are not reported; there is no assessment of cost-effectiveness vs simpler methods (e.g., self-consistency, few-shot rationales, verification pipelines).
- Reproducibility and data risks
- The 12 new Instruction Induction tasks are author-created and unvalidated for difficulty, leakage, or ambiguity; third-party validation and release notes for provenance are not provided.
- MedCalc re-evaluation on the Verified subset is mentioned but not quantified; impact of label corrections on headline conclusions is not rigorously summarized.
- Robustness and adversarial settings
- The system is not tested against adversarial or misleading CoTs, prompt-injection within think tags, or targeted attacks intended to force consensus on incorrect conclusions.
- Format and language variation
- No exploration of cross-lingual CoT transfer, code-based or formal proof rationales, or how paraphrasing/format transformations affect transferability and correctness.
- Theoretical grounding
- There is no formal framework connecting CoT transferability to properties like sufficiency, minimality, or invariance; a theory for when/why CoTs should generalize across models is missing.

- Dependencies include access to multiple heterogeneous LRMs, clear licensing for CoT reuse, standardization of think-tag formats, and evaluation metrics appropriate to the domain.
- Latency/cost of multi-model ensembling must be managed via caching, selective routing, or lightweight evaluators.
