[counterintuitive] Model makes an error early in its response and continues building on it instead of self-correcting mid-generation

Structure tasks so early commitments cannot cascade into unrecoverable errors. Use multi-turn workflows where each step is validated before proceeding. Use scratchpads that can be discarded. Never ask the model to produce long critical outputs in a single unstructured pass where an early mistake poisons everything that follows.

Journey Context:
Developers expect that if a model makes an error partway through a response, it should 'notice' and self-correct, the way a human would re-read and revise. But autoregressive models generate left-to-right and cannot revise previously emitted tokens. Once a token is generated, it becomes immutable conditioning context for all subsequent tokens. If the model states an incorrect intermediate result, that error becomes 'truth' for the remainder of the generation — the model conditions on its own mistake as if it were fact. The model cannot go back and change it. This is not a deficiency in reasoning but a fundamental property of autoregressive generation: each token conditions on all prior tokens, and prior tokens cannot be edited. Humans can revise; LLMs cannot. The solution is workflow design: break generation into validated steps, use scratchpads that can be discarded, and never ask the model to produce long critical outputs in a single pass.
