Why it matters
This is a concrete self-improvement loop with production economics attached: the model is being used to lower the marginal cost of running the model.
OpenAI says GPT-5.6 Sol analyzed production traffic, rewrote production kernels and helped tune its own draft model, contributing to a 20% reduction in end-to-end serving costs and more than 15% higher token-generation efficiency.
