Learn to evaluate reasoning in post-trained language models and understand their awareness of learned latent policies

advanced Published 29 Apr 2026
Action Steps
  1. Define the core competencies of language models, including awareness of learned latent policies and generalization of these policies
  2. Evaluate the reasoning capabilities of post-trained language models using metrics such as accuracy and robustness
  3. Apply techniques such as supplementary planning tokens to enhance the reasoning capabilities of language models
  4. Test the generalization of learned policies in language models using out-of-distribution data
  5. Compare the performance of different language models in terms of their reasoning capabilities
Who Needs to Know This

NLP engineers and researchers can benefit from this knowledge to improve the reasoning capabilities of language models, while product managers can use it to design more effective language model-based products

Title: Thinking About Thinking: Evaluating Reasoning in Post-Trained Language Models

Abstract:
arXiv:2510.16340v2 Announce Type: replace-cross Abstract: Recent advances in post-training techniques have endowed Large Language Models (LLMs) with enhanced capabilities for tackling complex, logic-intensive tasks through the generation of supplementary planning tokens. This development raises a fundamental question: Are these models aware of what they "learn" and "think"? To address this, we define three core competencies: (1) awareness of learned latent policies, (2) generalization of these p
