The new GPT-5.5 Instant is very smart, very intuitive, and very fun to chat with.
Rolling out now to everyone, starting with Pro and then Plus users. Free users should have the new GPT-5.5 Instant model by tomorrow.
We have a new version of GPT-5.5 Instant for you, and it's much more fun to talk to.
Our most-used model is now better at understanding the intent behind a question and adapting its response accordingly.
It also handles complex constraints more reliably and makes shopping and local recommendations more useful and cohesive.
Rolling out today to paid users, tomorrow to free users.
When Claude is working in a channel with four people, whose credentials does it use?
The answer: its own. When tagging Claude, Claude gets provisioned like any other teammate, with its own credentials.
We call this access model "agent identity". Here's how it works: 🧵
🚨 Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude.
Taught by the people who built it.
Free. No registration. No paywall.
I've seen $300 courses that don't cover what they teach in the first 8 minutes.
Watch it and bookmark it now.
Claude Tag is live. Tag @ClaudeAI in any channel. It reads the thread, does the work, and posts back where everyone can see it.

That’s the idea behind our new research on training models to be broadly and persistently beneficial. https://t.co/6Yw45s1RRq
