This is one of the most impactful developments for AI Search: we're finally getting 1st party data from ChatGPT!
Context: ChatGPT's Business Hub, a sort of Search Console for ChatGPT, is live and ready for signup!
I created an account. Here are my early observations:
1/ In the hub, you can see mentions, citations and website clicks on a rolling 28 day window. SUPER IMPORTANT: Business Hub (BH) only reports mentions that clearly reference a business website, whether linked or not. But the brand name alone appearing in an answer is not reported.
2/ You can also see the top 5 discovery topics (common themes in answers where the business appeared or was cited) and agent insights, if you create your own business agent.
3/ Users can select one of 3 business categories: services (not available yet), e-commerce and local. I was able to create an account for Growth Memo, even though it doesn't fit into any of the categories.
4/ The hub seems very geared toward e-commerce because businesses can upload product feeds. Makes sense imho. Companies can also create their own agents that appear organically or through ads. Before creating an agent, you need to verify yourself with a government ID.
5/ What is not yet available:
- Individual prompts
- Competitive share of voice or ranking benchmarks
- Audience-level segmentation
- A documented way to attribute conversions or revenue
- A documented public analytics API or bulk export

We've made it easier to get your repo running in Claude Code cloud sessions on Pro, Max, and Ultra.
Claude figures out what dependencies, network access, and API keys it needs, then saves the environment for next time. API keys are saved securely, so Claude never sees them.

OpenAI just updated its dataset on how people use ChatGPT.
I went through every file and found a few surprises:
1. Classic Google query types are now about half of all messages
- 48% of all messages were Google-style questions in September 2026, up from 43% in July 2024.
- The 48% breaks down into 20% simple searches (facts, products, recipes) and 28% Practical Guidance (how-to, tutoring, health, creative ideas).
- OpenAI sorts every message into work or personal. Google-style questions make up 53% of personal messages and 38% of work messages (September 2026).
- Personal messages grew from 48% to 68% of all messages since July 2024.
- Most of the rise comes from personal messages taking a bigger share, because they're search-heavy.
2. Commercial research at work grew 75%
Among US work messages (Q1 2025 vs Q3 2026):
- "Obtain information about goods or services": 1.7% → 2.9%
- "Determine values or prices of goods or services": 0.3% → 0.7%
- "Gather information from physical or electronic sources": 1.2% → 1.8%
Surprised me: researching a subject for work fell by up to two thirds (technology -66%, history and social issues -65%, health -42%). Product and price research grew.
3. Countries that use ChatGPT more use it more for search
- The quarter of countries with the highest ChatGPT use per capita put 24% of messages into simple searches in Q3 2026, vs 16% for the lowest quarter.
- Across ~150 countries, the correlation grew from 0.30 to 0.74 (Q1 2025 vs. Q3 2026).
4. Personal use grows faster than work
- OpenAI's classifier tags every sampled message as work-related or not (consumer plans only).
- Work went from 52% of messages in July 2024 to 32% in September 2026. The data only shows shares, so work messages could still be growing in absolute numbers.
In September 2026, the share of messages that were work-related was:
- Free: 25%
- Go: 42%
- Plus: 51%
- Pro: 68%

159 countries, 27 million sampled messages, July 2024 to September 2026

INTERESTING!
Bing Webmaster Tools is once again leading the charge: you can now see topics you're being cited for, how often they're cited and related grounding queries.
This is the closest we have to classic search data.
Your turn, Google!

Gemini 4 Argon is here.
It’s available globally today for developers and enterprises in the paid tier of the Gemini API and the Gemini platform, for Ultra subscribers in Google Antigravity, and Ultra and Pro subscribers in the Gemini app and Search.
Hope you all enjoy it!

RIP Git
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Developers wanted to resume Claude Code sessions so badly they built their own tooling for it. Shell hooks that save the session ID on exit. A published Ruby gem for bookmarking sessions by name. Custom zsh functions passed around like recipes.
All of that engineering existed to preserve a single string.
The sessions were never lost, which is what makes this a great product lesson. Claude Code stores every conversation as a JSONL file on disk, and the CLI could always resume them. The desktop app just couldn't see them. A GitHub issue back in April called it mostly a surfacing problem.
So for months, users filled the gap themselves. A SessionEnd hook here, a bookmarking tool there, each one a tiny patch over the same hole.
That's the strongest demand signal in software. A feature request costs the user 30 seconds. A workaround costs them hours, and they maintain it. When people start publishing packages to route around a missing feature, they've stopped asking and started paying with their own time.
The best product teams read this signal deliberately. Upvotes tell you what sounds nice. Workaround tooling tells you what people already can't live without.
And the reason this feature earned that level of desperation is worth sitting with. An AI coding session carries hours of accumulated context. Decisions made, constraints explained, dead ends ruled out. Losing it means paying that cost again. The session is quietly becoming the durable unit of work, and it just learned to travel.

We have a limited window to strengthen cyber defenses, and together with organizations including @AnthropicAI, @awscloud, @Google, @Microsoft, and @Oracle, we're calling for a global effort to give defenders the tools, resources, and support to protect the infrastructure we all depend on.
If we act decisively, we can turn today's AI advances into lasting improvements in security and make our digital world safer for everyone.

ChatGPT Work can now use its computer and browser to sign in to websites on web and mobile, without ChatGPT ever seeing your username or password.
That means you can ask it to:
• Set up utilities for a new apartment
• Book a DMV or passport appointment
• Check reimbursement costs through your insurance
• Find and book an in-network doctor around your availability
• Check when your car registration expires and prepare the renewal paperwork
• Compare your rental insurance policy with an issue you’re emailing your landlord about
• Find and save apartment listings that match your criteria
• Restock something just by uploading a photo
• Schedule a package pickup for a return
• Cancel tickets for a rescheduled trip
• Book a vet appointment
• Submit reimbursement paperwork for medical treatments
• Check resale sites for new drops and save things you might like
• Find candidates with specific experience and draft outreach
• Take invoices from your email and submit them to your accounting software
• Draft replies to rental property inquiries
• Fill out permit applications for your small business
• Add action items to a vendor portal based on a recent client call
• Analyze the latest ad campaign for your small business

More data than open-source AI is taking share from OpenAI and Anthropic. Open source has gone from 28% token share to 62% token share @vercel over the last 2 months. Chart from @rauchg
Super impressive given that the sum of OpenAI and Anthropic accelerated in July. So net token/AI infra demand accelerated even more than the acceleration we saw at the frontier. And suspect Grok growing even faster than open-source and we saw some of this in the @tryramp data.
Open-source AI taking share is positive for AI infrastructure demand as it lowers margins at the model layer and an open-source token costs just as much compute to produce as a frontier token. Nothing about open-source AI inference is “free.”
Most likely end state IMO is that closed, frontier tokens are 60-90% of economic value but only 15 to 25% of tokens.
