Hey everyone! We’re releasing new DeepSeek-V4.1-1017 Dynamic V3.1 (preview) GGUFs which showcases how Unsloth’s GGUFs retain the most accuracy for its size across 7 different benchmarks. We benchmarked ISTA's GSQ-RCO GGUFs but could not reproduce their reported results, even when using the highest scores. The biggest discrepancy was on AIME25 where they claimed 100% accuracy recovery to baseline, but was only ~91.88% in benchmark tests. Across AIME25, LiveCodeBench, GPQA Diamond, Aider Polyglot, and more, Unsloth Dynamic V3.1 outperforms GSQ-RCO GGUFs on nearly all metrics. Even our old v3 does better on nearly all metrics than ISTA. We ran each benchmark at least 3 times (AIME25 was 16 times) and averaged the results to ensure a fair, reliable comparison. More results coming next week! All benchmark data, methodologies and results are in our blog. Separately, for KLD, there were queries whether it’s a reliable measure of accuracy. The primary goal of quantization is to minimize KLD but also minimize disk space. If you get a KLD of 0, this means your quantized model == 16bit model, as logits are perfectly modelled. Our benchmarks show on KLD and top-1% across multiple domains (coding, agentic coding, chat etc), UDv3.1 does much better than GSQ-RCO across every domain. We show that lower bit quants do think somewhat longer than the unquantized model - we plan to investigate and make quants even better. However, we're still much ahead vs GSQ-RCO on even reasoning length as well, and provide plots for truncated answers in our blog. The model will be able to run on 128GB RAM/unified memory devices or even on 64GB RAM with engram offloading.
