User tests reveal GPT-5.6 Sol achieved up to 750 tok/s on Cerebras, marking a massive leap in inference speed. For context, GPT-5.5 typically runs at 70-100 tok/s and Gemini 3.5 Flash at 220-280 tok/s, making Sol roughly 2-3x faster than Flash. However, the user noted that Sol's output quality remains questionable.
