Reply — gabor (@gradientpull) · 5h: "why would higher weight similarity imply 'blindness'? obviously at Q1 weights are either fully or zero correlated, and quant necessarily shifts toward higher correlation. Doesn't mean multiple non-linear stacked layers with high correlation don't retain useful patterns." [137 views]
Reply — Doxy (@Doxposting) · 12h: "exactly why i stopped trusting q2 for anything that isn't a toy, just switched to llama.cpp with -q4_0 and the retrieval latency dropped while accuracy stayed solid
honestly if your vectors look like soup you're either quanting too hard or using a model that was never meant to" [3 likes, 665 views]

Continuation of the quantization/embeddings technical thread from the previous screenshot — replies debating why low-bit quantization degrades embedding discriminative power, with practical advice on quant levels for local LLM/embedding use.
