It's been a while since the last Gemma3NPC model release, in the mean while we were working on some other models like GemmaThink.
Now we are back with the newest Gemma3NPC-1b, trained using our RolePlay-NPCv2 dataset.
Training Parameters
We trained this model as a rank-32 LoRA adapter with two epoches over RolePlay-NPCv2 using a 80GB A100 in Google Colab. For this run, we employed a learning rate of 2e-5 and a total batch size of 8 and gradient accumulation steps of 4. A cosine learning rate scheduler was used with an 150-step warmup. With a gradient clipping of 1.0.
With this new 1b model, we used much more aggresive training parameters and added some NSFW dataset to experiment with the results. We noticed a few really interesting responses:
There seems to be some sign of "reasoning"

The model is less likely to break out of character
Something up to the users to explore for themselves, remember to provide a roleplaying prompt first!
Future Work
Now, we will be focusing on further improving Gemma3NPC, not only just through training parameters.
Better data (most of our data are old and need an update), either collected or synthetically generated.
Better & new models, expand beyond Gemma3 model family, our next goal is a Qwen3 based model.
Adding GRPO into the training loop.
These improvements serve our ultimate goal of creating an small agentic NPC model, with good RP quality and tool-calling for dynamic in-game interactions.
We also plan to create some sort of a Unity game demo,it's on its way.
