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.
OpenAI API
API access to GPT-4o, o1, and other OpenAI models including embeddings and image generation. The most widely used LLM API in production.
