[synthesis] Optimizing cost and latency for AI chat products with varying query complexity
Route queries dynamically between a fast, cheap model for classification/routing/simple tasks and a powerful model for complex reasoning, using the fast model as the orchestrator.
Journey Context:
Using a single large model for all tasks is prohibitively expensive and slow. Using a small model for everything sacrifices quality. ChatGPT's observable API behavior and the architecture of tools like Cursor reveal a pattern of model cascading. A fast model \(e.g., GPT-4o-mini\) handles the initial prompt, decides if tools are needed, and formats the output, only invoking the heavy model \(e.g., GPT-4o\) for the core reasoning step. This hides latency and reduces cost by 10-100x for simple queries. The synthesis is that production AI products are rarely single-model; they are pipelines orchestrated by cheap, fast models.
