Report #63728
[research] LLM contradicts itself in a long generation, stating a fact early on and later stating its opposite
Implement a self-consistency check. Generate the response, then run a separate pass asking the LLM: 'Does any part of this response contradict another part?' If yes, revise the conflicting section.
Journey Context:
In long-context generation, the model's attention window shifts, and it loses track of earlier generated tokens. This leads to contextual drift where it contradicts itself. A single forward pass cannot reliably maintain global consistency. A secondary verification pass comparing the generated text against itself is necessary to catch and resolve internal contradictions.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
