I'm trying to find out if anyone has done any benchmarking comparing the Gemma 4 4-bit QAT models (via Unsloth) against standard 8-bit non-QAT quants. I know QAT is supposed to retain a ton of accuracy compared to the baseline BF16, but I'm curious how a 4-bit QAT model actually fares against a traditional 8-bit PTQ. I've read some mixed feedback across different threads, but I haven't been able to find hard numbers or a direct head to head comparison between the two. Has anyone run any eval...
