Gemma-3-1B-IT — Knights-and-Knaves SFT

Paper Link: https://arxiv.org/abs/2605.28814

Cold-start supervised-fine-tuned (SFT) model of google/gemma-3-1b-it on the Knights-and-Knaves (K&K) logic-puzzle dataset.

For the post-trained model on top of this SFT model, see Xkev/gemma-3-1b-it-kk-bes.

Training

• Base model: google/gemma-3-1b-it
• Dataset: K&K puzzles (1k subset), formatted as chat with reasoning + JSON answer
• Framework: verl sft_trainer
• Hyperparameters: lr=1e-5, weight_decay=0.01, lr_warmup_ratio=0.1, cosine schedule, epochs=3, dtype=bf16

Intended use

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