GPT-5.6 Sol: When the Model Tunes Its Own Inference

The most unexpected part of OpenAI's GPT-5.6 Sol release is that the model itself contributed to optimizing its own inference pipeline — not just tuning outputs, but reshaping the compute graph under the hood.

The blog describes a feedback loop where Sol analyzes its own runtime characteristics, identifies inefficiencies, and proposes alternative execution strategies. Some of those
