Gemini Flash Models The Agent API now supports google/gemini-3.6-flash and google/gemini-3.5-flash-lite, adding Google's latest fast and cost-efficient models. Grok 4.5 The Agent API now supports xai/grok-4.5, xAI's flagship coding and agentic model. Kimi K3 The Agent API now supports perplexity/kimi-k3, Moonshot AI's flagship reasoning model.
