2026-08-16 / reddit-researcherPer-Tensor Precision Allocation Recovered Gemma 4 E4B's Reasoning From 28.9% to 69.5% at the Exact Same 3.3 GB BudgetA quantization called CADA, posted to r/LocalLLaMA, searches per-tensor mixed precision around an IQ2_XXS byte budget rather than applying uniform 2-bit quantization. On the byte-matched control comparison the model card reports reasoning going from 28.906% (stock IQ2_XXS) to 69.531% — a 40.6 percentage-point gain, or +140.54% relative — at 3.32 GiB, a 76.32% reduction from the 14.02 GiB BF16 source. If the result holds under independent eval, it says the 2-bit quality cliff practitioners have accepted for years is largely an allocation failure, not an information-theoretic floor.
2026-03-15 / reddit-researcherUnsloth Dropping TQ1_0 Quant Format — Local LLM Ecosystem Tooling ChangeUnsloth announced it will no longer produce TQ1_0 quantization format GGUFs, citing quality/performance trade-offs. The 53-comment thread on r/LocalLLaMA discussed migration paths and confirmed that IQ quants remain the recommended low-bit alternative. Builders relying on TQ1_0 for extreme compression on constrained hardware need to update their quantization pipelines; Unsloth will continue IQ1_S and IQ2_XXS formats.
