Benchmark bias: why bf16 scores mislead real-world quant users
AuspiciousApple · reddit · 2026-08-18
The author criticizes model benchmarks for using bf16 weights while users mostly run 4-bit quants. There is a lack of systematic evaluation comparing bf16 vs various quantization formats (Q8/Q6/Q5), especially for complex tasks like long-context recall. A call is made for standardized harnesses to measure real performance.
