Opus 5.5 in the age of personal software 🤯
I just moved: 2 empty walls, plus the art & plants I carried over.
I gave Claude a few pics of where I sit, and it built a 2D + 3D model of the room with everything at real size.
Here's a glimpse: before I hung anything, and after.

I asked Claude to grab my actual prompts. It called the artifact Corner Hang, which is fun:
I started with:
[pic from my webcam] This is my background, it directly, and almost evenly, faces a corner. I want to create a way of editing these walls in 3d space with 2d images of items and then viewing it from this view please. Please make it so i can upload images, with rough dimensions. In the meantime I will add some here to have in there.
Then steered here:
• add 4 items from [link to where I purchased the art] [list of items] please
• 11.7 x 16.5 in roughly?
• this is totally separate from the other things in this folder btw, a totally separate project
• also 6 of these, true skateboard size please [link to where I purchased the art] [screenshot of the set]
• green white orange light blue dark blue yellowish
• no top right orange one,
• I'm going to give you the exact dimensions from the camera to different parts of the room. From the camera to the corner of the room is about 12 feet 8 inches. From the camera to the light switches It's about 10 feet and from the camera. So the wall is about nine feet. [I actually read these out loud into the mic as I was measuring]
• remove this please [screenshot of a hint bar]
• this could be much smaller and optional please [screenshot of the card next to a selected piece]
• option to hide ask claude please
• allow drag and drop directly into the scene please
• option to move something to other wall somehow when selected

Claude Tag can now use your personal connectors in Slack, and it asks you to ✅ first.
Now when you're the only one with access, just @𝚌𝚕𝚊𝚞𝚍𝚎 and keep going.
Rolling out now on Team plans, Enterprise next.

Cloud sessions in projects have convinced me we’re capable of feeling superhuman at times.
Mobile + cloud + project coordination + long running execution have let me fire off & steer from anywhere.
When I occasionally need that project to connect locally it’s a superpower.
Cloud sessions are officially available and out of research preview! They let you keep Claude Code working, even when your laptop is closed.
Existing subscribers get a one-time credit to try them: $100 on Pro, $250 on Max.

Opus 5.5 built a fun little demo that x-rays a make-believe house with pipes, wires, ducts and all.
It finds four mistakes and fixes them before anything is built.
Now picture an actual expert builder making a tool like it their own. 🔧

Launch day for Opus 5.5!
It's a lot of fun to play with, and it's faster and cheaper per task than Opus 5.
Inspired by @kevin_t_ngo's incredible art, I started seeing where my imagination would take me.
Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.
It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.

Weekend project idea: Try Claude projects... I'll see myself out.
Most people on Pro/Max who've reached out should be in now, but still working DMs through and responding!
DM me your email for early access (if you're ok with a few rough edges with existing projects)!
Today we're rolling out Projects in Claude Code on desktop and web.
A project is one conversation with Claude. It splits the work into threads itself, runs them as parallel cloud sessions, passes context between them, and keeps going when you leave.
In beta for select users.

Can't let Lydia have all the fun! Want early access to Claude Projects too?
DM me your email and we'll get you in.
Rough edges included, more on those below 😊
We're rolling out the new version of Projects in stages, but if you want early access DM me your email and we can let you in sooner!
Just a heads up there may be some rough edges if you already have existing projects, we're still working on a way to carry them over smoothly

What makes Claude Projects so interesting is that it handles teams of agents really well, you talk to a main orchestrator agent and it spins up specialists. Basically it creates an organization to solve your issue, mixing expensive and cheap agents depending on your preferences.
For example, I asked Fable in Claude Projects to select famous historical mysteries that it could try to resolve. It initiated research agents, selected the mysteries based on data it could access, and spun up eighteen separate threads, each with an agent each focused on one mystery. Then each thread launched additional agents (simulating avalanches, breaking codes) before summarizing those and passing them to still more agents for write up and another set of skeptical agents to fact check. It did this over a day of work, with the central orchestrator agent organizing it all.
The results were interesting if you like historical mysteries. They are also for fun and certainly not definitive or guaranteed error-free (but they are also mostly reasonable & grounded in the literature). historical-mysteries.netlify…

Projects have changed not only how I interact with Claude but how I code.
I stopped managing sessions. I just send thoughts as they come, Claude splits them into threads, and the project remembers how I work. It's where I do a ton of my coding now.

I really lean on Claude projects to move further faster.
For this launch, it built up an incredible understanding of the messaging and content that was going on, and it had all my connectors but also kept its own memory as we talked.
Projects now run from one conversation, starting in Claude Code. You describe what needs doing, and Claude directs parallel threads that keep working after you close your laptop.
In beta today for select Pro and Max users in cloud sessions; coming to all Claude users soon.

Projects are how I write a lot of my code these days. Really excited for everyone to try the new experience! Rolling out now

We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so.
Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

Here's how our team uses Claude Tag for on-call:
When an alert fires in Slack, Claude pulls metrics, diffs deploys, and checks flags. It finds a likely cause and proposes a fix, which we can approve and merge. Every minute counts, so we love that it starts right away!
