  title: SambaCloud Chat API
  description: 'SambaCloud is SambaNova''s managed inference API for open-source models

    (DeepSeek, Llama, Gemma, MiniMax, gpt-oss). The HTTP surface is

    OpenAI-compatible: chat completions, completions, embeddings, and

    model listing endpoints all match the OpenAI shape so existing OpenAI

    clients can be pointed at `https://api.sambanova.ai/v1` by changing

    base URL and API key.
