max_paperclips · x · 2026-08-06

Developers have discovered a new built-in web search feature in DeepSeek's API. By using the Responses API with the deepseek-v4-flash model and adding websearch to the tools, DeepSeek executes the search directly on its servers.

This eliminates the need for third-party search APIs or extra keys, significantly simplifying integration and maintenance for developers.
