Tell an agent it has 1M token budget and it reasons 3-5x longer: a metacognition experiment

paraschopra · x · 2026-09-10

Paras Chopra tested agents that are told their token budget for the run inside the prompt. Two agents ran the exact same model, settings and prompt — one told it had a 10k token budget, the other 1 million.

For the same task, the agent told it had the higher budget produced 3-5x longer reasoning. A clear sign of meta-cognitive abilities beyond mere task execution. He notes this isn't a separate thinking-effort setting — only the stated budget differed, yet token expenditure changed dramatically.
