DeepSeek AI API

High-performance LLM access featuring OpenAI-compatible endpoints and industry-leading price-to-performance ratios.

DeepSeek delivers API access to its flagship models, DeepSeek-V3 and DeepSeek-R1, via a streamlined REST interface. The platform maintains full compatibility with the OpenAI SDK: developers simply swap the base URL to integrate. Performance is aggressive: input costs start at $0.14 per million tokens while output remains $0.28 per million tokens. Features include context caching (reducing costs by up to 90% for repeated prompts), function calling, and JSON mode. It is a drop-in replacement for teams scaling production AI without the premium overhead of legacy providers.
