LFM2-2.6B-ttt-rl-merged
Merged standalone model after the first round of CISPO training for Tic Tac Toe.
This is the result of merging anakin87/LFM2-2.6B-ttt-rl (LoRA adapter) into anakin87/LFM2-2.6B-ttt-sft (SFT base). It serves as the base for the second round of RL training.
This is an intermediate checkpoint from 🎓 LLM RL Environments Lil Course, a hands-on course on building RL environments for Language Models, where models learn from rewards, not examples. It walks through the full process of turning a small open model into a specialist that outperforms a large proprietary one on a specific task (Tic Tac Toe). The final model is anakin87/LFM2-2.6B-mr-tictactoe.

Competent player, but still falls into fork traps against the optimal opponent.
