Exclusive: Mind Robotics, the startup founded by Rivian Chief Executive RJ Scaringe, raised an additional $400 million from investors, the latest bet on an AI-powered bot revolution in manufacturing on.wsj.com/4ttmxpP

Today we’re introducing Forus and announcing $160M to build the foundation for modern medicine. Science should be the only limit to medicine. Today it isn’t. Drug discovery is moving faster, but the system that turns it into real-world treatment isn’t. forus.com/blog/forus-ann…

Today we're launching the Open Defense Initiative: up to $5 million in @depthfirstlabs credits for critical open source projects to find and fix real, exploitable vulnerabilities. The timing matters: frontier models can autonomously discover and exploit vulnerabilities in widely-reviewed codebases. Open source models will catch up soon, and when they do, bad actors will have unfiltered access to these capabilities. We have a narrow window to harden critical software before that happens. This is the time to act, but until today frontier-level security, like what Mythos offers, has been reserved for a handful of large companies who are required to pay a lot for access. depthfirst is not only comparable in performance but also goes significantly beyond surface level findings, highlighting real, exploitable vulnerabilities due to its understanding of the system’s context and ability to verify like an attacker would. depthfirst found vulnerabilities in FFmpeg that Mythos missed, at a tenth of Anthropic's self reported spend. We want every defender to have these capabilities, starting with the open source projects the world runs on. If you maintain a critical open source project, apply for Open Defense credits through the form in the comments.

I'm thrilled to announce @nova_ai's $40M funding across a Series A led by @chemistry and a Seed led by @Accel, with participation from @conviction and SAP's venture arm SAP.iO.

Today, we are thrilled to officially launch RadixArk with $100M in Seed funding at a $400M valuation. The round was led by @Accel and co-led by @sparkcapital. RadixArk exists to make frontier AI infrastructure open and accessible to everyone. Today, the systems behind the most capable AI models are concentrated in a small number of companies. As a result, most AI teams are forced to rebuild training and inference stacks from scratch, duplicating the same infrastructure work instead of focusing on new models, products, and ideas. RadixArk was founded to change that. We are building an AI platform that makes it easier for teams to train and serve the best models at scale. RadixArk comes from the open-source community. We started with SGLang, where many of us are core developers and maintainers, and expanded our work to Miles for large-scale RL and post-training. We will continue contributing to both projects and working with the community to make them the strongest open-source infrastructure foundations for frontier AI. We would like to thank our long-term partners, contributors, and the broader SGLang community for believing in this mission. We're also grateful to @Accel and @sparkcapital, NVentures (Venture capital arm of @nvidia), Salience Capital, A&E Investment, @HOFCapital, @walden_catalyst, @AMD, LDVP, WTT Fubon Family, @MediaTek, Vocal Ventures, @Sky9Capital and our angel investors @ibab, @LipBuTan1, Hock Tan, @johnschulman2, @soumithchintala, @lilianweng, @oliveur, @Thom_Wolf, @LiamFedus, @robertnishihara, @ericzelikman, @OfficialLoganK, and @multiply_matrix among others. Thanks for the exclusive interview with @MeghanBobrowsky at @WSJ about our vision.
