量子位 · wechat · 2026-08-14

OpenAI announced the Ultrafast preview tier, accelerating GPT-5.6 Sol by up to 14x to 750 tokens/sec without compromising intelligence. This leverages Cerebras wafer-scale engines to bypass traditional memory bandwidth bottlenecks.

Additionally, the ChatGPT desktop app introduced Computer History. It tracks user interactions like clicks, keystrokes, and app switches, allowing the AI to answer context-aware questions like "where did I leave off?" without taking screenshots or recording audio. Raw data is kept locally for 48 hours and not used for training.
