## Summary

OpenAI announced that the first update of its 28‑Day continuous improvement project has increased the default speed of GPT‑6 Astra and GPT‑6.1 Sol by about 50%. The company said users should feel the effect within 2 hours, though the author has not yet verified the claim.

The update also marks a shift for Claude Cowork, which will begin running in a cloud environment from October 6th (US time). Each session will be sandboxed in a virtual workspace, reducing local resource usage and file‑deletion risk.

Other items include Google Drive and Docs adding native Markdown support, Cognition’s Devin gaining a “Dreaming” memory‑graph feature, and a rumored quiet release of Nano Banana 2.1 to Google Flow. The article also notes a 33% drop in Japanese voice‑input errors for Aqua Voice and a new Audible feature that lets users talk to book characters.

## Key points

- OpenAI’s 28‑Day update raises GPT‑6 Astra and GPT‑6.1 Sol speed by about 50%
- Claude Cowork will run in a cloud sandbox from Oct 6th US time
- Google Drive and Docs now support previewing and editing .md files directly

## Why it matters

Speed improvements and cloud migration make GPT‑6 more usable for developers and non‑engineers, while Markdown support in Google tools eases AI‑generated content collaboration.
