Leaked GPT 5.6 Sol Hits 1400 tokens/s, Experts Warn of Tool Call Bottlenecks
AccBalanced · x · 2026-08-20
A leak suggests GPT 5.6 Sol achieves a generation speed of 1400 tokens/s, vastly outpacing Claude Sonnet 5 (50-70 t/s) and Gemini Flash 3.7 (350 t/s). However, technical commentator Josh Clemm warns that integrating this into agents will make tool calls the primary bottleneck. Without optimizing those calls, users pay extra for minimal overall speed gains.
