AI Launch Profile
DeepSeek-V4.1-Flash-1017
DeepSeek released the October 17 update to DeepSeek-V4.1-Flash, with official weights under the MIT license. The exact repository is DeepSeek-V4.1-Flash-1017; the rolling API alias deepseek-flash does not pin that artifact. DeepSeek reports improvements in reasoning, coding, agent tasks and visual benchmarks. Those performance claims have not been independently retested by Kingy in this recovery pass. Use the versioned model files and prompt-encoding instructions when reproducing the release.
