Agents
CrewAI 1.15.22 adds an llm_overlay context variable that routes individual agent roles to different models
Released 16 Sep 2026, the version lets a crew bind specific roles to specific models at runtime through `llm_overlay` rather than fixing the model per agent at construction — the practical lever for putting a cheap model on extraction and an expensive one on synthesis inside one crew. The same release records reasons for deployment creation failures, captures human feedback and pause events in tracing, validates platform integrations during crew setup, exposes the CrewAI Platform application catalog, and loads text file URLs through a safe fetcher.
