The DeepSeek API now natively supports the OpenAI Responses API format and is specifically adapted for Codex. Users can refer to the official documentation and complete the Codex configuration with a one-click configuration script.
The thinking modes of V4-Pro and V4-Flash now support three thinking effort levels: low / high / max. In real-world usage, users can flexibly choose based on task complexity: use low for simple tasks, high for daily Agent tasks, and max for more complex scenarios. For setup instructions, please refer to the official API documentation: Thinking Mode.
With the official release of the DeepSeek V4 model family, we will update and adjust API pricing. To allocate resources more reasonably, we will adopt peak/off-peak pricing, with off-peak prices set at half of the peak-hour prices, encouraging users to schedule their tasks based on actual usage. The new prices will take effect at 16:00 (UTC Time) on August 16, 2026.
