AI agents are moving into production much faster than they can be secured - @arcjet has now launched its answer to the problem.

You can't detect prompt injections with a single, general-purpose model.

Dev laptops and security analysis are two examples where inputs that look like attacks are perfectly normal.

Today @arcjet is announcing a family of custom-trained models to tackle this.

- Arcjet Himalia 1, a general-purpose prompt injection model (live now!)
- Arcjet Thebe 1, designed to protect coding agents
- Arcjet Carme 1, for autonomous security agents

Our benchmarks on open datasets show Himalia 1 delivering 0.978 precision and 0.964 recall.

Sign up to @arcjet today to try it out! More details about the benchmarks and training in arcjet.com/blog/introduci…

In 2000 the US and Europe held 46% of the global PCB market. Today it’s ~6%.

@CircuitHub's Grid is changing that: it already builds tens of millions of dollars of electronics a year, twice as fast as Shenzhen - and capacity will scale 5x this year.

PCBs made in America. Twice as fast as Shenzhen.

Today @CircuitHub is unveiling The Grid, our factory-scale robot in Massachusetts that builds circuit boards on demand.

No changeovers, no per-design setup. Prototypes and production batches, fully automated.

Agentic AI can now take real actions - its mistakes range from clumsy to harmful to malicious.

@Arcjet's new Agent Runtime Security gives engineering teams enforcement as soon as an agent acts, with sequence-aware checks so risky patterns get caught.

When AI was just a chatbot, the worst thing it could do was be wrong. That is no longer where the risk sits. Today we are announcing Agent Runtime Security.

“AI is really transforming what you can do ‘in silico’ before you do it in the physical world. That is driving a massive acceleration in those deep-tech fields. So the capital intensity to get those returns has really changed.” @carinanamih in today's @FT: ft.com/content/0c4401…
