UnverifiedVerifiable rewards refer to types of problems whose correctness can be automatically determined by a program, such as mathematical proofs, code execution results, and game outcomes77% similarUnverifiedIndependent verification means that the reviewing party and the generating party belong to different systems, models, or toolchains, and follow a set of criteria that are determined in advance and can be applied repeatably.76% similarUnverifiedA Verification Signal is the feedback source for measuring the correctness of an agent's output; in coding scenarios, compilers, unit tests, and type checkers provide machine-readable deterministic signals, whereas open-ended tasks such as document writing and requirements organization lack automated criteria, so the agent cannot close the loop and optimize without human intervention.75% similarUnverifiedOutput validation is an independent check layer between "call succeeded" and "task succeeded," and commonly used methods include JSON Schema validation, required-field checks, numeric range checks, date expiry checks, and consistency checks against user constraints.74% similarUnverifiedThe deterministic verifier is responsible for evaluating attributes that can be parsed from code and rendering, such as element alignment, size matching, and correct content presentation; such rewards are verifiable and reproducible.74% similar
