Arc-Intelligence/ATLAS-8B-Thinking

Arc-Intelligence/ATLAS-8B-Thinking is an 8 billion parameter teacher model developed by Arc Intelligence, based on Qwen3-8B, designed to improve the reliability and performance of student LLMs through adaptive guidance. It addresses the brittleness of standard RL fine-tuning by using a diagnostic probe to assess student reasoning and providing tailored intervention. This model is a core component of the open-source ATLAS Framework, specializing in training and enhancing other language models without performance degradation.
