Mixing Agent Models error
❓API❓AI steps
Hey 
Anyone else getting API 400 errors when mixing Anthropic and Gemini models across agents connected via exit conditions?
I have a multi-agent setup (Supervisor → 3 specialist agents). When the Supervisor (Haiku 4.5) routes to an agent running Gemini Flash 3, I get:
The request gets rejected instantly – never reaches the model. Same agents work fine when all running Anthropic models. Gemini agents also work when tested in isolation.
Seems like the conversation context format breaks when handing off between different model providers. Is this a known limitation or a bug?
Thanks!
