After the introduction of the GPT-5.6 Sol model, developers carried out further optimizations, resulting in a 20% reduction in service costs due to production GPU kernel improvements and more than a 15% improvement in token-generation efficiency thanks to enhanced speculative decoding. These changes enable lower operational costs and higher throughput.
