Today’s three

DevDay’s headline agent is dots, powered by GPT-6 Astra.

OpenAI · Read 3 min

• OpenAI’s post: dots are always-on agents “built to handle everything,” powered by GPT-6 Astra.
• They are in ChatGPT on web, mobile, and desktop for Pro, Business Premium, and Enterprise in eligible markets.
• You set what a dot may do alone, when it should ask, and what it must never do. It runs on its own cloud computer.

The keynote was 10:00 a.m. Pacific at Fort Mason. This item is only the dots thread. GPT-6.1 Sol, Ultrafast, and Codex Security Cloud are separate posts in On X, each linked to its own status.

OpenAI also posted “Our biggest DevDay ever, don’t be late” before the keynote. That call is on the strip, not a fourth story.

Washington and Beijing opened a super intelligence dialogue. The next exchange is by November.

The White House · Read 3 min

• The 25 September White House fact sheet says the two leaders agreed to call these technologies “super intelligence,” not “artificial intelligence.”
• They established the U.S.-China Super Intelligence (SI) Dialogue on risks and benefits. The next exchange is by November 2026.
• They also agreed a bilateral channel for SI incidents. The sheet does not say what counts as an incident.

The same sheet says both leaders intend to attend each other’s G20 and APEC summits. The city and month on the events list come from CNBC’s comparison of the readouts.

This is a named channel. The fact sheet does not describe a joint development program.

The same visit fixed two lines: no Iranian bomb, and no waterway tolls.

• The fact sheet says the leaders agreed Iran can never have a nuclear weapon.
• They agreed no country or institution may impose tolls on international waterways.
• The sheet does not say whether the Qatar-mediated talks expected this week have begun.

Yesterday’s edition reported that meeting window. This one does not add an outcome the fact sheet does not contain.

Glance

Codex Security Cloud will scan a whole GitHub repo and draft fixes for review.

• OpenAI says cyber-capable models through Daybreak Blue are included by default.
• It scans entire repositories and keeps reviewing new commits.
• It investigates findings, drops duplicates, and prepares fixes for review.

@OpenAI

Introducing dots, powered by GPT-6 Astra. Remarkably capable, always-on agents built to handle everything.

The agent launch from today’s Fort Mason keynote.

@OpenAI

GPT-6.1 Sol: near-Astra intelligence for a fifth of the price. It’s the most cost-efficient model for its performance available today.

@OpenAI

This is Ultrafast. Our premium speed tier, Ultrafast offers up to 8x faster token generation (300 tokens per second) in Codex and up to 6x in the API.

The speed tier. The thread says it is live for GPT-6 Astra, and that Sol on Ultrafast is still coming.

@OpenAI

Codex Security Cloud is getting a major upgrade, with access to cyber-capable models through Daybreak Blue included by default.

A security-product change from the same day, kept out of the three.

@OpenAI

Our biggest DevDay ever, don’t be late.
