X-Coder-RL-Qwen3-8B: Code Reasoning Foundation Model
IIGroup's X-Coder-RL-Qwen3-8B is an 8 billion parameter language model specifically engineered for advanced code reasoning. It is built on the IIGroup/X-Coder-SFT-Qwen3-8B base model and uniquely trained using the GRPO (Generalized Reinforcement Learning with Policy Optimization) method on a fully synthetic dataset, IIGroup/X-Coder-RL-40k. This specialized training approach, part of the X-Coder RLVR recipe, enables the model to excel in complex competitive programming scenarios.
