DeepSeek Homepage Still Links to the V4 Preview X Post

Checked on June 9, 2026: DeepSeek's English homepage still links directly to the April 24 @deepseek_ai V4 Preview post, while current official docs keep V4 Pro and V4 Flash as the active model names and mark legacy aliases for July 24 retirement.

What we verified on June 9, 2026

  • DeepSeek's English homepage still links directly to an X post from @deepseek_ai as its public social anchor.
  • That linked post is the April 24, 2026 DeepSeek-V4 Preview announcement, which states that V4 Preview is live and open-sourced, names DeepSeek-V4-Pro and DeepSeek-V4-Flash, and says the API was updated that day.
  • DeepSeek's current official API docs still present V4 Pro and V4 Flash as the active public model names, with OpenAI-format and Anthropic-format base URLs unchanged.
  • The same official docs still mark deepseek-chat and deepseek-reasoner for deprecation on July 24, 2026 at 15:59 UTC, which matters for older snippets that still use those aliases.
