DeepSeek V4.1 Flash is now the default brain in XinYu chat, including on the free plan

  • DeepSeek V4.1 Flash is the new default brain: it's what XinYu chat opens with, and it's available on the free plan. It thinks before it acts.
  • About 55% cheaper for paid users.
  • Text nodes and storyboards can now use DeepSeek V4.1 Flash and it can look at images you attach. For videos, switch to Gemini 2.5 Flash; if you pick the wrong one you'll be told before anything is charged.
  • DeepSeek V4 Flash has been retired. Chats and text nodes that used it switch to V4.1 Flash automatically.

Every model's price is shown in the picker, so glance at it before you switch.
