GPT 5.6 Sol reportedly hits 1,400 tokens/s, 4-25x faster than rival fast models

Nick Dobos claims GPT 5.6 Sol runs at 1,400 tokens/s — for comparison, Claude Sonnet 5 is 50-70 tokens/s and Gemini Flash 3.7 350 tokens/s. That would make OpenAI's smartest model 4-25x faster than competitors' fast models: "blink and it's done." Unverified.
Dan Jeffries amplifies, asking when Sol, Astra, Kimi, and GLM will match this speed — and suggesting the already-fast pace of releases is about to accelerate further.
