MinCoder-4B-Exp Overview
MinCoder-4B-Exp is an experimental 4 billion parameter model developed by beyoru, fine-tuned from Qwen3-4B-Instruct. Its core innovation lies in its training methodology: a custom reinforcement learning (RL) framework that rewards the model based on whether its generated solutions pass automated test cases. This approach mirrors the evaluation process found in programming challenges like LeetCode, moving beyond reliance on labeled ground truth answers.
