[synthesis] Using a single frontier model for all AI product features causes high latency and cost

Implement a model cascade. Route tasks to the smallest capable model: use a tiny model \(e.g., 1-3B params\) for autocomplete/fuzzy matching, a mid-tier model \(e.g., Haiku\) for intent classification and routing, and a frontier model \(e.g., Opus/GPT-4\) only for complex planning and multi-step code generation.

Journey Context:
Many products launch using GPT-4 for everything, resulting in slow, expensive interactions \(especially for autocomplete\). Analyzing Cursor's architecture and Anyscale routing patterns reveals that successful AI products are essentially model routers. Autocomplete requires <100ms latency, which frontier models cannot meet. By classifying the user's intent first with a fast model, you can send 90% of requests to cheap, fast models, reserving the heavy compute for the 10% of tasks that actually require deep reasoning.
