DeepSeek just dropped V4.1-Flash-1017 with open weights (MIT). It has the same architecture as V4.1 Flash, roughly 550B backbone with 8B/16B active, but posts big agentic gains: Terminal-Bench 31 to 42 and DeepSWE 77, ahead of Opus 5. The 1017 checkpoint is about 510GB, while the existing V4.1 Flash Spark EXL3 recipe already runs on 2 DGX Sparks, so a local version should follow fast. Re-quant time. #AI https://huggingface.co/deepseek-ai/DeepSeek-V4.1-Flash-1017
