Chat digest: Astra capacity crunch, DeepSeek V4.1 Flash benchmarks, Codex quota bug, and why xHigh saves more credits than Medium

2026-09-09 群聊日报

OpenAI's Tibo publicly admitted unprecedented Astra demand and may pause new Pro subscriptions; users report lag even during off-peak hours and frequent WebSocket disconnects. DeepSeek V4.1 Flash scored 81.2 on OpenDesign's design benchmark—98% of Astra's quality at 1.4% of the cost—but the API's mandatory training clause and not-so-cheap real pricing gave users pause. A Codex quota display bug caused panic today; Tibo promised compensation but most users never got it. A counterintuitive finding: xHigh mode actually consumes fewer total credits than Medium because it plans more accurately and loops less. Also: Jacob Coxon quit with a warning about AI arms-race risks, Apple announced the foldable iPhone Duo starting around $2,800, and the Navier–Stokes proof cost roughly $15M in API fees.
