Feedback Mechanism
A form of test-time scaling in which a model generates a preliminary answer, then obtains feedback signals through an external verifier or self-evaluation and revises its reasoning. Its effectiveness depends heavily on the quality of the verification signal.
Timeline (last 90 days)
The three dimensions of depth, width, and feedback share the same reasoning budget pool; increasing depth means reducing opportunities for width exploration, and investing in feedback iterations may sacrifice the depth of a single reasoning pass.
For mathematical proof tasks, depth scaling is usually more effective because the logical chain needs to remain coherent; for open-domain question answering, width scaling has more advantages; for code generation and debugging, feedback mechanisms are most valuable because compilers and test cases provide reliable external verification signals.
