Our new multi-model agentic security system brings together more than 100 specialized agents across frontier and custom models to find exploitable bugs, delivering top performance on the CyberGym benchmark. We used it ahead of Patch Tuesday to help find and fix 16 vulnerabilities. Today we’re announcing that customers can sign up to test it in private preview.

Super fun hanging with @PaarupLuis at Connected Stack this morning, we covered: - How the best evals are customer outcomes - Agents need opportunities to make mistakes to do their best work, not excessive guardrails - Why custom models create out-performance in vertical markets

Your data is your edge, but only if your AI is built on it. Rent a generic model and so can your competitor. The companies with an edge are deploying custom models that they own and improve over time. Our co-founder @rhythmrg recently stopped by @southpkcommons to share how companies are owning their intelligence with Applied Compute.

Your team knows how your business works. How do you build AI that does, too? At the builders' breakfast today with @UseCorgi, @fotor_com, and BuildHer Labs, our Head of EMEA, @TiffanyWang98, shared how businesses can build private, custom AI around their own knowledge and workflows. Your documents and policies give the model context. Fine-tuning helps it follow your processes and communicate in your brand’s voice. But these materials often contain sensitive information that needs to stay within your organisation. FLock provides the infrastructure for businesses to train and fine-tune domain-specific models through federated learning without exposing their raw data, and deploy them on infrastructure they control. A router connects each request to the appropriate model and applies rules on information access and responses. Smaller, custom models can handle routine work, while larger ones support more complex reasoning. The end goal is to build AI capabilities your organisation owns, shaped around real workflows and the people who use them. It was an insightful meetup where we discussed with fellow builders what enterprise AI solutions look like in practice. Thanks to @claudiaamaggi, Nora Chen, and Shreya Choudhuri for bringing us together, and to everyone who joined us at Corgi Cafe!
