The cheapest way to use the GPT API

UberLLM lets you call GPT models at pass-through provider pricing (no inference markup), or drop to much cheaper open-weight models by changing the model id — all with the OpenAI SDK and one key. UberLLM gives you one OpenAI-compatible API key and base URL for 380+ models, routing each request to the cheapest healthy provider with no inference markup and free starter credits.

FAQ

Is there a cheaper GPT API?

UberLLM charges GPT at pass-through pricing and makes it trivial to switch to cheaper models (DeepSeek, GLM, Qwen) for cost-sensitive workloads — same SDK, one key.
