Developer uses test suite to gate LLM model selection, saving costs

A developer has devised a workflow to optimize LLM usage by employing a tiered model system. Instead of randomly selecting a model, the system first attempts tasks with a free or low-cost model. If this model fails, as determined by existing tools like test runners, linters, or type checkers, the task is then escalated to a more powerful, expensive model. This approach prioritizes tasks that have verifiable outputs for the lower tier, reserving higher-cost models for subjective or high-risk tasks where errors are more costly. AI

IMPACT This workflow could significantly reduce operational costs for AI users by intelligently routing tasks to the most cost-effective model.
