What's genuinely new
Astra's launch expands what agent-like tasks you can hand over, Grok 4.6 tweaks its performance on long jobs, and Grok Bot lets tasks persist and overlap in one pooled environment.
What the makers claim
OpenAI's naming Astra universal and critical on cyber capability, xAI declaring Grok 4.6 their fastest and most intelligent, and both firms' benchmark talk.
Where it helps
When you set workflows to run overnight and come back in to pick them up, or when you delegate a document redraft and need to know what files are being touched.
Where it doesn't
One-off tasks you supervise live, where the work happens in front of you and nothing sensitive stays running in the background.
ConfirmedOpenAI started rolling out GPT-6 Astra on 3 September 2026, initially to a limited set of organisations and, over the following days, to ChatGPT Plus, Pro, Business and Enterprise users, the OpenAI API and AWS. It is aimed at research, coding, computer use, document, spreadsheet and presentation work and long-running agentic tasks. The API model id is gpt-6-astra, with a 1,050,000-token context window, up to 128,000 output tokens, a knowledge cutoff of 30 April 2026, text and image input with text output, and adjustable reasoning effort. Its headline API pricing, $10 per million input tokens and $50 per million output tokens, matches Claude Fable 5.1, while the two differ on cache economics, where Fable 5.1 reads cache at $0.25 per million tokens against Astra's $1. OpenAI says Astra is the first model it has rated at the Critical cybersecurity capability level under its Preparedness Framework, its stated reason for the phased rollout.
What we'd doCheck for any still-open credentials or personal files the Bot or agent left behind.
Still unknown- How any of these shifts actually handle the real leftovers, old logins, saved downloads, unsent drafts, on your own account.
- Whether persistent Bot sessions create any overlap or confusion with your daily files when you run several tasks side by side.
