OpenAI API
API access to GPT-5, GPT-5.5, o3/o4 reasoning models, and the Responses API; plus embeddings, image, audio, and Realtime endpoints. The most widely deployed LLM API in production.
DeepSeek API
DeepSeek's API provides access to DeepSeek-R1 and DeepSeek-V3 — frontier models matching GPT-4 performance on benchmarks at dramatically lower per-token costs. Its reasoning model (R1) supports extended chain-of-thought for complex coding and math tasks.
