Unsloth Runs DeepSeek V4.1 Flash Locally

• Unsloth AI says DeepSeek V4.1-Flash-1017 can now run locally, with 1-bit quantization retaining about 88.2% accuracy while shrinking size from 508GB to 250GB, a 52% reduction.
• It says the model runs on a 128GB+ RAM device and calls V4.1 Flash 1017 the strongest open model to date.
• Daniel Han says the team worked on a llama.cpp implementation for DS4.1-Flash and made Unsloth dynamic GGUFs, finding Q6_K approximately equals MXFP8 while IQ4_NL loses a tiny bit of accuracy, and that the engram can stream fully from disk.
• DeepSeek says DeepSeek-V4.1-Flash-1017 is live on its website, app and API, with stronger benchmark performance, faster task completion and shorter outputs than the previous version, and is optimized for DeepSeek Harness, Tencent CodeBuddy and WorkBuddy.
