Wait you're say Gemma was unusable or GLM? I quite like 5 series with OC.

Both. I could not use Gemma 4 for more than two days without having to switch. GLM is somewhat better, but still generally terrible compared to Opus.

I'm not surprised that Opus was better. My hope is the average user might be able to have needs met running a Gemma4 model locally for OC - the compression they've achieved is quite impressive
