Libraries

How to use Xkev/gemma-3-1b-it-kk-bes with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="Xkev/gemma-3-1b-it-kk-bes")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Xkev/gemma-3-1b-it-kk-bes")
model = AutoModelForCausalLM.from_pretrained("Xkev/gemma-3-1b-it-kk-bes", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

# Gemma-3-1B-IT — Knights-and-Knaves BES

Paper Link: [https://arxiv.org/abs/2605.28814](https://arxiv.org/abs/2605.28814)

Post-trained model on top of [`Xkev/gemma-3-1b-it-kk`](https://huggingface.co/Xkev/gemma-3-1b-it-kk) using Bidirectional Evolutionary Search (BES) on the [Knights-and-Knaves](https://huggingface.co/datasets/K-and-K/knights-and-knaves) (K&K) logic-puzzle dataset.

For the SFT cold-start this was initialized from, see [`Xkev/gemma-3-1b-it-kk`](https://huggingface.co/Xkev/gemma-3-1b-it-kk).

## Training

- **Base model**: `Xkev/gemma-3-1b-it-kk`
- **Dataset**: K&K 5k train split
- **Framework**: [verl](https://github.com/volcengine/verl) `main_ppo` with a bidirectional goal-tree search agent loop
- **Search**: budget=200 rollouts, decompose interval=10, backward model `google/gemma-3-1b-it`
- **Hyperparameters**: `lr=1e-6`, batch=32, `ppo_epochs=1`, `clip_ratio=0.2`, `grad_clip=0.3`, `kl_coef=0`, `dtype=bf16`

## Intended use

Research on logical reasoning and post-training. Not intended for general dialog or production.

## License
