We’re excited to share that Cyrus has successfully completed its SOC 2 Type II audit 🔒
Building on Type I, our Type II audit independently assessed how effectively our security controls operated over time.
Another milestone in securing AI development workflows.

@CyrusAgent offers a free and open source way to plugin to that agent platform on Linear, and connect Claude Code or any harness, and build YOUR inspect that you own
A pattern I keep seeing at the most AI-forward companies: they stop shopping for an agent and start building one.
@zachbruggeman at @tryramp built Inspect, a coding agent that knows Ramp's codebase, conventions, and test suite. You hand it a Linear issue the same way you'd hand it to a teammate. It reads the docs, writes the code, runs the tests, and comes back when they pass.
Off-the-shelf agents are trained on the world. Yours is trained on your company, which is why we've built Linear to be the place any agent plugs into. Your agent, your rules, one system of record for everyone doing the work.

Cool investigative work from @entrecurious's team to benchmark the DGX station for local and open inference! @NVIDIAAI's machine is slowly rolling out, and fun to see what people do with it.
Recently at Cornell I used it for synthetic RL environments and agent training---high risk moonshot research that turned out to be high reward! kilian-group.github.io/blog/…
I squeezed lot of compute out of the DGX station for RL training. The bottleneck was throughput on agent rollouts, so the machine's optimizations for agent inference actually enabled fast training.
Can you run the frontier at home, at work?
We dug deeper to find out every detail of the DGX Station, and what kinda hardware it's taking to run GLM 5.2.
Is the GLM they say is running the same GLM as the benchmarks? Not always, but that doesn't mean it's a write-off.

50 Demos in 50 Days, Day 3 Demo.
Running Kimi K2.7 using openrouter and opencode INSIDE @linear using @CyrusAgent.
I found out EXACTLY how many times cheaper it is to run K2.7 Code and if it really performs like Opus.
That's Claude Opus 4.8 vs Kimi K2.7. And in our testing the cheaper one made a design leap we didn't expect.

Demo 2/50!
ScheduleWakeup tool!
This is incredible tool you NEED to be making use of if you are not already, and thankfully, we've now fixed a bug with it in Cyrus.

I'll be doing Cyrus office hours, an open invitation to come and chat Cyrus, Claude Code and Linear.
Cyrus is the open framework to build your company's internal agent.

Introducing Cyrus Skills. Customize how your Cyrus works.
Every company runs on knowhow trapped in heads, Slack, emails, Notion - how you review code, ship deploys, triage bugs. Skills are how you make that knowhow legible to your Cyrus.
Curated: high-quality skills across Dev, DevOps, Security, Design. One click to install.
Custom: capture your team's playbooks. Your Cyrus uses them like built-ins.
Scoped: target any skill to specific repos, Linear teams, or labels.
AI isn't something you bolt onto the side of a company. With skills, your company's knowhow becomes the way your Cyrus works.

just days since @cursor_ai announced the cursor sdk, and WHILE at stripe sessions we shipped improved cursor support for @CyrusAgent with it.
Let composer-2 cook!
thanks especially to @SamSokolin who quickly triaged sandboxing which was broken in the first release on our feedback.

will be switching to it from the bare cursor cli for @CyrusAgent cursor support! sweet!

@CyrusAgent stars are growing rapidly.
It's because it's the only open source agent that gives you a
- @linear agent
- @github agent
AND
- @SlackHQ agent
In one installation, to tackle your end-to-end software automation
Cyrus has come to Slack. You can now mention Cyrus directly in Slack.
Ask it anything:
"What's the status on the tickets you're tracking?"
"Review the PR on the auth refactor"
"Build me a settings page for the new API"
It answers instantly. In the thread. Connected to your Linear, GitHub, and repos.
Need something built? Cyrus creates the ticket, writes the code, opens the PR, and pings you back in Slack.
People are switching from other agent setups because of this; not just for smarter AI, but better integrations.
Launch Week complete:
Day 1: Multi-model support (Cursor, Codex, Claude)
Day 2: Instant code reviews on GitHub
Day 3: Cyrus in Slack

The waiting is the most expensive part of shipping software. Not the code. The queue.
You know how this goes. You open a pull request, tag a reviewer, and... wait.
A day passes. You ping on Slack.
Two days. You rebase because main moved ahead.
Three days. The review finally lands, but you've already context-switched to the next thing. You barely remember why you made that decision.
Today, that changes.
You can now @ mention Cyrus directly on any GitHub pull request and get an instant, thorough code review.
This isn't a lint check. Cyrus reads the full context of your PR and your repo, then leaves the kind of review your senior engineer would - edge cases caught, architectural trade-offs questioned, concrete improvement suggestions.

Today, on Launch Week Day 2, we are launching something that's been requested many times, and for good reason.
Directly @ mention Cyrus on Github (@cyrusagent) to get a response!
You can get Cyrus to leave a code review, to answer quick questions about the PR, or to submit a follow up Linear issue for something you see.
AND Cyrus now gets notified if you leave a review on a PR opened by Cyrus with a "change request", offering the chance to automatically get those changes in.
And we're not done yet, tune in tomorrow for one more major launch to get excited about. Cyrus will be joining the chat.
Engineer says "I can't today, I'm busy". We built Cyrus to jump in in those exact moments.
Drop a hard Linear issue → ~15 min later: tested PR + deploy preview ready to merge.
Day 1 of Launch Week: Cyrus now supports Cursor agent + OpenAI Codex (alongside Claude).
⚡️ Composer 1.5 ~250 tok/s (~4× faster)
🎯 Codex 77.3% Terminal-Bench 2.0
🚅 Codex Spark up to 1,000 tok/s + BYO subscription
You pick the agent and the model. Cyrus does the work.

Exciting customer news 🚀
@mihail_eric the @MonacoGTM team are out of stealth.
They’re building the first AI-native revenue engine for startups—automating everything from ICP discovery to personalized outreach to CRM workflows.
The incredible team is backed by @foundersfund, @garrytan, and @peterthiel.
Monaco uses @CyrusAgent to ship faster. When we first spoke, Mihail shared how context switching was slowing his team down. Watching him solve that—and now launch something that will help thousands of founders—is what startups are all about.
Grateful to be part of Monaco’s journey. Can’t wait to see what they ship next with Cyrus!
