DeepSeek has officially announced the launch of the DeepSeek-V4-Pro model, focusing on significant production-level improvements for Agent capabilities.
Key updates include:
- Flexible reasoning effort: Both V4-Pro and V4-Flash allow users to adjust reasoning intensity based on task complexity (low for simple tasks, high for daily Agent workflows, max for complex scenarios).
- Native API support: Optimized compatibility with the OpenAI Responses API, featuring one-click setup specifically tailored for Codex.
V4 Pro is now accessible via the app and web through 'Expert Mode', with API model names remaining unchanged.
