Leaker @NFTChen reports (unconfirmed) that DeepSeek quietly rolled out a DeepSeek V4.1 Flash 1017 build:
- The deepseek-flash backend has switched to a new version (internal codename 1017); it briefly appeared in the model list, isn't directly callable yet, but is already serving traffic
- Users report it feels smarter with more concise answers
- It's only been about a month since the last official release, suggesting additional training
- The leak claims this is likely a staging build for V4.1 Pro, which may already be in gray-scale testing — watch for model routing changes
Staying true to form, DeepSeek shipped it on a Saturday with no announcement. This is third-party observation; the company hasn't confirmed anything.
