  They upgraded the agent under the same API name.

 DeepSeek-V4.1-Flash-1017. Open weights · MIT. Released 2026-10-17.

 On that day DeepSeek shipped Flash-1017 on its website, app, and API — better agent scores, faster runs, shorter outputs — and dropped the checkpoint on Hugging Face under MIT. A multimodal MoE with a 552B backbone: about 8B parameters active in prefill, 16B in decode, and a one-million-token window. Builders who never changed their endpoint woke up to a different mind. Search and Fetch went public the same afternoon.

 Same endpoint. Same price. Different mind.

 We file Flash-1017 as the day an open weight arrived wearing yesterday’s API badge — and the ledger recorded a silent upgrade, not a press tour.

 The cheap mind did not ask permission to improve.
