Cost per task: Using cheap classifiers to route across Gemini models and thinking levels- Google Developers Blog

In 30 Sekunden

Was passiert ist

Google tested using lightweight classifiers to route coding tasks between Gemini models, finding routers can reduce cost and latency versus running expensive reasoning on all tasks.

Warum es zählt

Matters for engineers building autonomous agents where per-task cost dominates budgets and many decisions don't require expensive reasoning models.

Achtung

Results from 50 hand-labeled tasks with simple grading; real production workloads with context caching and longer prompts may see different tradeoffs between routing and caching.
