Cyber threats are accelerating, so I've open-sourced my Vercel Security Audit skill.
To run it, reply to this post with:
@bot read this article and run the vercel-security-audit skill on my Vercel team
Your agent crashed halfway through a turn. What happens to the work?
durable-harness records each step, so a new function picks up the interrupted turn instead of starting over.
Works with Claude Code, Codex, OpenCode and Pi. eve and fx already run this way.
Try it: durable-harness is open source at github.com/vercel-labs/durab…

Terence Tao on Numberphile, after OpenAI's dump of AI-generated proofs: mathematics is "transitioning from an era of proof scarcity to proof abundance."
"Now we're drowning in proofs, but we're not getting all the understanding that we used to get."
Swap proofs for pull requests and it's the same story in software. Code is abundant now. Understanding of the code is the scarce thing.

How to make your coding agent nearly 3x faster in one line:
/model deepseek/deepseek-v4.1-flash-1017-ultrafast
Works in fx on @vercel AI Gateway. Same prompt, 1.7s vs 4.7s 🖤
One model string in fx, Claude Code, Codex or Cursor:
deepseek/deepseek-v4.1-flash-1017-ultrafast

What would you run at 1,000 tokens/sec?
Three services on port 3000. No collisions.
portless now supports Docker Compose. portless compose up gives every service a named URL.
Routes survive container restarts, and compose down cleans them up. No more remembering which port is which.
Try it: portless compose up

Boris Cherny (@bcherny), creator of Claude Code, on Lenny's Podcast: a year ago a model could run 15 or 30 seconds before going off the rails. Now some Opus runs go for hours or even days.
Once an agent runs for hours, a single request is the wrong shape. You need durable execution: steps that checkpoint, retry and resume after a crash or a deploy. That's what durable workflow engines like Vercel's Workflow SDK are for.

agent-browser, for your whole computer.
agent-desktop gives any coding agent computer use on macOS, Windows and Linux.
It runs in the background while you keep working, and agents can work in parallel, each with its own cursor.
Try it: npm install -g agent-desktop

Aaron Levie (@levie) on the role he sees every enterprise needing: an internal forward-deployed engineer.
Is this what AI adoption inside a company actually looks like. Someone who understands both the work and the tooling, sits with a team, and wires agents into how they really operate.
If you're an engineer who likes talking to the business, this is the most leveraged seat in the building right now.

AI is writing more of your code. Who's checking it for security?
Vercel Security Review scans every push for vulnerabilities, and Vercel Agent can open a PR with the fix.
It only reviews what changed, so it finishes in seconds and runs on every deploy.
Try it: turn on Security Review in Vercel Agent settings, or pull findings into your own agent with Vercel security vulnerabilities. Reviews are free until 10 Nov.

Your agent can now say "I'll do that tomorrow at 9" and actually do it.
Vercel Schedules lets apps and agents create, change or cancel one-time and recurring jobs while they run.
No redeploy, no database, no polling job. The request arrives when it's due.
Vercel Schedules is now in public beta.
Agents and applications can now schedule and manage their own work.
▪︎ Define static jobs once in code
▪︎ Create dynamic ones at runtime
▪︎ Run in any environment, including preview
vercel.com/blog/introducing-…
Try it: call Schedules.create() from the JS SDK, or add a schedule to vercel.json. Public beta.
