UberLLM is an OpenAI-compatible API that works with every major model. You keep the OpenAI SDK (or Anthropic SDK for /v1/messages) and change only the base URL and key — then call GPT, Claude, Gemini, DeepSeek, GLM, Qwen, Llama or Kimi with the same code. UberLLM routes each request to the cheapest healthy provider.
