OpenAI announced that its GPT-5.6 Sol model autonomously fine-tuned a smaller model, Luna, with only a "fairly vague prompt." On OpenAI's internal recursive self-improvement benchmark, Sol scored 16.2 points higher than GPT-5.5. OpenAI believes that an "automated researcher" is within reach. This achievement indicates that large language models have a degree of autonomous research and improvement capability, potentially accelerating AI self-evolution. For teams working on AI automation and model optimization, this progress opens new possibilities but also requires attention to safety and controllability.
