Sam Altman weighed ChatGPT against an almond -- AI Brief September 4

Good day %%first_name%%. OpenAI shipped GPT-6 on Thursday, called it the start of the AGI era, and then most of you could not use it — partly by design, partly because ChatGPT, Claude and Grok had all fallen over that same morning. Anthropic, meanwhile, taught Claude to work your Mac while you are still sitting at it. A YC startup watched 17,000 coding-agent sessions to learn which vendors the agents buy when nobody is looking. And Sam Altman would like to talk to you about almonds.

OpenAI Declares the AGI Era. Access Pending.

OpenAI

What happened: On Thursday, September 3, OpenAI released GPT-6 Astra and called it “the world’s most intelligent and aligned model.” It is rolling out first to “a limited set of organizations,” with Plus, Pro, Business and Enterprise users, the API and AWS Bedrock following “over the coming days.” API pricing is $10 per million input tokens and $50 per million output, a step up from GPT-5.6 Sol, with a “fast mode” at double that.

Why it matters: The headline claim is not chat, it is work: OpenAI says Astra fills out forms, updates a CRM, lays out a circuit board and builds a slide deck in your own template, and does it in about half the time per task of its predecessor on the OSWorld computer-use test. It also crosses OpenAI’s “Critical” line for cybersecurity — it found two previously unknown zero-day bugs during testing — so the public version refuses to write exploits and ships with a misalignment monitor that can pause your task mid-run.

What everyone’s saying: OpenAI president Greg Brockman told reporters “it’s not unreasonable to feel that we are now in the AGI era,” per Axios, while 9to5Google headlined the launch as the most intelligent model “that you can’t use just yet.” The Hacker News thread spent its first hour watching the announcement page return a 404, noticed the 99.9% ARC-AGI-3 score carries a footnote about OpenAI’s own custom harness, and did the arithmetic on 2.5x Sol’s output price.

My read between the lines: Read OpenAI’s own comparison table before you read the press release. On the Artificial Analysis index — the one Fable 5.1 topped yesterday — Astra scores 61.2 to Fable 5.1’s 65.7, and it trails on Humanity’s Last Exam too. OpenAI is not claiming the smartest model. It is claiming the best one at using a mouse, and it published the numbers that say so. The AGI line is for the people who will never scroll that far.

OpenAI spent Thursday telling you what an agent could do for you in the coming days. Viktor is what one does for you today. It is an AI agent that lives in your Slack, connects to 3,000-plus tools, and hands back finished work — the report, the dashboard, the campaign, the code — rather than a chat window you have to babysit. Not a chatbot. A coworker. New readers get $50 off their first month. Hire Viktor →

ChatGPT, Claude and Grok All Went Dark at Once

9to5Google

What happened: On Thursday morning, September 3, Downdetector lit up for ChatGPT, Claude and Grok at the same time. OpenAI confirmed elevated errors on ChatGPT and Codex, Anthropic posted an incident covering Fable 5.1, Mythos 5.1 and Opus 5 across Claude, the API, Claude Code and Cowork, and Cursor confirmed its own outage downstream of the Claude and Grok failures. Gemini stayed up. ChatGPT was back within the hour; Anthropic said Opus 4.8 and Opus 5 were still erroring after the rest of Claude had recovered.

Why it matters: Three companies that compete with each other do not usually break together, which is why the eyes went to the shared layer underneath: Quartz and 9to5Google both noted Microsoft Azure was reporting disruptions at the same time, and all three chatbots lean on Azure for part of their infrastructure. Nobody has confirmed the link. If it holds, “multi-vendor” was never the redundancy people thought they were buying.

What everyone’s saying: 9to5Mac pointed out the timing — the outage landed hours before OpenAI’s GPT-6 launch — and the Hacker News thread on the launch guessed the two were connected when the announcement page briefly vanished. Earlier this summer we covered ChatGPT and Claude going down the same day; this is that story with Grok added to the pile.

My read between the lines: Every AI vendor sells you a model. Every AI vendor rents the same three clouds. The outage lasted about as long as a coffee break, and the interesting part is how many people discovered during that break that they no longer had a way to work without one of these three tabs open.
