量子位 · wechat · 2026-09-21
Per aggregated leaks (unofficial), Anthropic will skip 5.1/5.2 and launch Claude Opus 5.5 this Tuesday, reportedly outperforming OpenAI's GPT-6 Astra and priced at 60% of Astra's rates. Context: Ramp data shows Astra at 13% of tracked enterprise AI spend vs Claude Fable's 8%, and OpenAI led Anthropic on OpenRouter spend last week for the first time in 2.5 years. One tester reportedly had Opus produce a 93-second animation written entirely as a Python+NumPy pixel engine rendered frame-by-frame and encoded with ffmpeg.
