A team has developed OpenMythos, an open-source large language model specifically trained for cybersecurity tasks. The model was created to address the shortcomings of general-purpose LLMs in handling security-related information. The training process involved supervised fine-tuning on cybersecurity data, followed by a reinforcement learning from verification (RLVR) stage using GitHub repositories with paired vulnerable and fixed code branches to improve accuracy and calibration.
