Introducing Connections.
Set it up once → every OB-1 session just works.

Connect:
• Individual accounts (e.g. @linear)
• Org accounts (e.g. @sentry)

Plus:
@github @braintrust @baseten @stripe …and more
Powered by @WorkOS

See OB-1 with @linear below!

One setup in the dashboard.
After that:
→ any engineer
→ any CLI session
→ any agent

can securely use those connections.

Here’s OB-1 fixing issues directly from @sentry ↓

RT @daljeet_v: Benchmarks, Accountability, and What Matters

Our Terminal Bench submission did not meet the standard we set for ourselves.…

OB-1 now supports BYOK!

Just add your keys from OpenAI or Anthropic and you're ready to go.

Introducing PM Mode in OB-1!

Run /init-pm and OB-1 will analyze your integrations to learn how your company works.

Switch to PM Mode (shift+tab), and you'll never run out of ideas on what to build.

See it in action for OpenClaw 👇

The OB-1 free tier is back up with $10/day in credit!

We onboarded ~10k users yesterday, which briefly strained the system. After removing some spam accounts, everything is running normally again.

If you are running into issues, please report via /bug in CLI or joining Slack.

Your coding agent just got its own computer.

The best coding agents don’t just write code, they ship it 🚀

All OB-1 sessions now include the @vercel CLI as a preloaded skill: deploy, preview, and manage projects without leaving the agent.

Here’s where OB-1 is going:

– Auto-generates evals from past PRs, then climbs them with custom models
– Builds its own skills, hooks, and rules from a codebase and session history
– Background agents in safe sandboxes that keep working while you context-switch
– Session sharing version control around prompts, instead of source code
– Lives where you already work: Slack, Linear, GitHub, Graphite
– PM mode so it never runs out of ideas

Today’s coding agent teams still employ hundreds of human engineers, which we find telling.

We’ve kept our team small, consisting entirely of IOI/IMO medalists, to make one bet: OB-1 will build OB-1 faster than any human team.

We’re just getting started. Be sure to follow @openblocklabs for future updates.

Coding agents 💚 Modal Sandboxes

Your coding agent just got its own computer.

ob1 --sandbox

Powered by Modal.

2/ Most coding agents run directly on your machine: eating memory, slowing your computer down, and even crashing your terminal.

--sandbox moves all of that off your laptop and into an isolated cloud environment on @modal

Your agent gets its own machine with your repo and local environment cloned instantly.

OB-1 now reads .agents/skills

One shared skills folder, usable across agents.

I’ll be at NeurIPS in San Diego this year!

Reach out if you want to talk about coding agents (+ our upcoming CLI launch @openblocklabs), domain-specific RL, open-source.

So much fun hosting the CMU builder night tonight; packed with demos, energy, and great people.

Gave a sneak peek of @openblocklabs' upcoming CLI agent, OB-1!

s/o @waynesutton @convex for the space :)
