DeepSeek Adds Streaming and Non-Streaming Thinking Samples

Migrated with permission from DeepSeek V4 Pro, a related editorial property operated by our team.

Checked on July 8, 2026: DeepSeek's official docs sitemap currently lists dedicated thinking-mode sample pages for both non-streaming and streaming chat completions, clarifying when reasoning_content is just captured, when it is ignored in ordinary follow-up turns, and how delta.reasoning_content should be accumulated separately from visible answer text.

What we verified on July 8, 2026

DeepSeek's official docs sitemap currently lists dedicated non-streaming and streaming thinking-mode sample pages.

The non-streaming sample shows a plain two-turn OpenAI-compatible flow: capture reasoning_content and final content, append the assistant message, then send a second user turn.

The same non-streaming page explicitly notes that earlier reasoning_content will be ignored by the API in that ordinary follow-up case, which is an important boundary for teams that over-engineer replay behavior.

The streaming sample shows delta.reasoning_content and delta.content arriving separately, and its code accumulates them into different buffers before constructing the next-turn assistant state.

This is protocol and support coverage only. It does not create any new plan card, stock promise, or pricing change in this repo.
