   ISTA disputes Unsloth's DeepSeek-V4.1-Flash-1017 benchmark comparison

   ISTA said its DeepSeek-V4.1-Flash-1017 benchmarks used a 128K context window, reasoning effort of 50 and an output budget of up to 128K tokens. It attributes the discrepancy with Unsloth's published comparisons to different constraints, saying Unsloth imposed a strict 32K reasoning budget, and denies using hidden hyperparameter adjustments to favor its models. ISTA said its code is available on GitHub, its papers are on arXiv and additional comparisons were underway. It invited independent reproduction using its stated settings.

   Unsloth releases preview GGUFs for DeepSeek-V4.1-Flash-1017

   Unsloth released preview Dynamic v3.1 GGUF quantizations for DeepSeek-V4.1-Flash-1017 and said they can run on devices with 128GB of RAM or unified memory, or with 64GB of RAM using engram offloading. The vendor reported stronger results than ISTA's GSQ-RCO GGUFs on nearly all listed metrics across seven benchmarks, but said it could not reproduce ISTA's published AIME25 result. Unsloth averaged at least three runs per benchmark, with 16 runs for AIME25.
