What's the minimum viable quant for agentic tasks? Qwen 3.8 27B says Q4 is the floor
overdoingism · reddit · 2026-10-19
A Reddit user asks what quantization level people consider the floor for agentic work. With Qwen 3.8 27B on cross-domain ERP retrieval tasks with tool calling, they found official or well-known community Q4 quants are the minimum usable; dropping to FP4 formats like MXFP4 noticeably increases error rates on their evals. They acknowledge the small sample size and invite others to share their quants, tasks, and cutoffs—useful data for local agent deployments.
