It appears Google Cloud has blocked our account, and so some services are unavailable We’ve escalated this to Google and will keep people posted. Deepest apologies.

The Railway dashboard is currently unavailable, and all running Railway services are down. We're working with our upstream provider to restore service. Updates: status.railway.com/

Pi gang -- what am I doing wrong?! I really want to use Pi because of its customizability, but the harness itself seems subpar for me. I've noticed that Pi Opus4.7 requires more steering as well.
I've been test-driving Claude Code versus Pi GPT5.5 the past week. Here are the results. 159 Pi sessions vs 60 CC sessions. On the same project, Pi needed 2x the corrections and got cursed at 3x as often. Opus 4.7 has been getting anecdotally getting dumber, but it looks like I'm keeping CC as my daily driver after all. Prompt: "Stalk all my Claude Code (~/.claude/projects/) and Pi (~/.pi/agent/sessions/) sessions the past week, and tell me which one required less steering, and pisses me off the least."

On a related note, Pi GPT5.5 seems to be amazing at Rust. @thisismahmoud maybe that's why you prefer it 😛

Share how much you've spent on agentic coding! curl -fsSL "agentic-coding-spend.ray.cat" | bash -s Works with Claude, Codex, & Pi. Most of it is estimated from consumed tokens according to your sessions, except when using Pi.

If you're not using ui.sh/ for design, you're missing out It works amazingly well with Opus 4.7 when you let it go wild with vague and not-too-descriptive prompts

Information architecture is about to become VERY important. In a world where LLMs are the retrieval layer, your schema becomes your moat. Garbage graph in, garbage answers out.

SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI. The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models. Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together.

Jokes aside, this is gonna be interesting. X is going to have a shit ton of GPU by EOY, & Cursor has a healthy userbase they need a deep default frontier model partnership. So, maybe we'll have a use for Grok beyond "is this true?" soon

Something we/I been working on for a long time and I am over joyed it's out! Railway is now on @stripe. Sign up for Railway, deploy databases, apps, and storage directly from the Stripe CLI. One command for infrastructure. See the demo!

Tip: Use `/fast on` with Claude to generate prompts that you can pass onto other agents to implement. This helps you craft faster and more detailed prompts without burning through tokens with /fast for implementation. Also works better with large context windows.
