Subbarao Kambhampati critiques LLM reasoning:

In a recent YouTube episode, Prof. Kambhampati argues that while LLMs excel at many tasks, they possess significant limitations in logical reasoning and planning. His ICML tutorial delves further into the role of LLMs in planning, supported by various papers on self-correction issues (Large Language Models Cannot Self-Correct Reasoning Yet).

Challenges in intrinsic self-correction benchmarks:

There are concerns about the feasibility of benchmarks where an LLM has to correct its own reasoning trajectory due to an initial error, possibly making it an unrealistic setup. The discussion highlights the difficulty in comparing model performances when the benchmark involves models intentionally generating faulty trajectories for self-correction.

LLMs struggle to self-correct effectively:

Research indicates that LLMs often fail to self-correct effectively without external feedback, raising questions about the viability of intrinsic self-correction. A summary of the study on self-verification limitations reveals that models experience accuracy degradation during self-verification tasks as opposed to using external verifiers.

Feedback loops in LLM reasoning:

A member noted a peculiar aspect of LLM reasoning where an initial mistake could be corrected later due to context changes in the generated output, hinting at potential stochastic influences. This implies that while LLMs might demonstrate some capacity
