A developer explored how imposing token budgets on large language models affects their behavior, finding that constraints shift the AI's optimization from generating maximum output to completing specific tasks. By using a tool called Token Sensei, which tracks exact token usage and pauses execution when a budget is met, the developer observed that models like Claude Sonnet 4.5 prioritized task completion over unconstrained generation. This approach requires external enforcement, as models are inherently over-optimistic about budget and fine-tuning alone is insufficient. AI
IMPACT External budget enforcement may be necessary for LLMs to optimize for task completion rather than simply maximizing output.
