OpenAI's technical report reveals that GPT-5.6 is now applied in production to optimize its own runtime environment, including analyzing traffic, adjusting request routing, rewriting low-level kernels, and optimizing speculative decoding. These improvements reduced end-to-end service cost by 20% and increased token generation efficiency by over 15%.
