If you fine-tune custom models, reserve dedicated GPU endpoints, use Llama or Mistral, or need embeddings — we do not serve those. Image generation we do: Nano Banana Pro (Gemini 3 Pro Image), Nano Banana 2.1, FLUX.2 Pro, FLUX.1 Schnell, SDXL Turbo, FLUX.2 Klein, Qwen Image 3.0, Seedream 5.0 Pro, Seedream 4, Bria FIBO 1.5, Bria FIBO 2.0, GPT Image 2, GPT Image 2.5 Flare and GPT Image 2.5 Sunburst.
Yes for chat: streaming, tools, and usage.cost all work through the official OpenAI SDK. json_schema strict mode is model-dependent — the Claude models do not support it, so use a tool with strict: true there.
