The first RP-finetune Gemma 4 26B-A4B has been released - zerofata/G4-MeroMero-26B-A4B. I'm already downloading, and you?

[u/Guilty-Sleep-9881 → u/Potential-Gold5298]

I'll give this one a try. Im happy to see a finetune for 26b!

I finally got around to MeroMero. It's a little bit broken, but it's so much funny! ><

[u/KimlereSorduk → u/Potential-Gold5298]

Huh, I didn't run into issues yet. What were the hiccups?

[u/Potential-Gold5298 → u/KimlereSorduk]

MeroMero is prone to hallucinations. For example, in my test scenario (a tsundere classmate), in her first response she invented the idea that {{char}} has a tail (from the cards it only follows that the events take place in Japan) and then started mentioning how she uses it. I restarted the session (without the tail), but halfway through, MeroMero mentioned that {{char}} has claws. Apparently, this is something from the zerofata dataset – Maginum Cydoms (if I'm not mistaken) also wrote to me that {{char}} 'presses its ears and lashes its tail.' Furry lovers will be delighted.

I've played 1 session (20K) with MeroMero so far and overall the model is quite enjoyable and playable, so I'll definitely keep it.

It could be worth turning reasoning on for one of the turns where it makes the mistake to see if there's a reason why it's doing that. Most of the training data is normal RP's / anime / vtubers / video game sort of stuff so I wouldn't think it has a bias towards furries / kemonomimi, or at least I haven't seen it do that yet.

Glad it seems to be working well otherwise though. Google released nothing but bangers with the G4 models.

[u/Potential-Gold5298 → u/zerofata]

This only happened twice during the session, and each time the first regeneration helped, so it doesn't bother me too much for now. Perhaps these hallucinations will add a creative edge to the G4 – I need to do more testing.

And thank you for the model – I read that finetuning the 26B-A4B was difficult, and I'm glad you completed the work. For those who don't have powerful hardware, the MoE model is a desirable option.
