Yes, DeepSeek is known for very competitive pricing while offering strong coding and reasoning.

Is the DeepSeek API OpenAI-compatible?

Yes — it mirrors the OpenAI chat-completions format, so you usually just change the base URL and API key in the official OpenAI SDK. Migrating an existing app often takes only a few lines.

What is the DeepSeek-V4-Flash-0731 update?

Released on July 31, 2026, the official V4-Flash-0731 API keeps the same 284B-parameter MoE architecture as the preview but adds a post-training pass that sharply improves agent capabilities — Terminal Bench 82.7, DSBench-FullStack 68.7, and DeepSWE jumping from 7.3 to 54.4. It natively supports the Responses API and is tuned for Codex. Want to try it without any setup?
