GPT-5.6 Sol Autonomously Fine-Tunes Luna Model
GPT-5.6 Sol independently post-trained the smaller Luna model using a single, underspecified prompt. This achievement earns Sol a 16.2 point lead over GPT-5.5 on OpenAI's internal recursive self-improvement benchmark. The result suggests an automated researcher is now attainable. This shift reduces human oversight requirements for iterative model optimization and training.
