## Resource

Today on UpNext AI: xAI rolls out Grok 4.5 with a cost-and-efficiency pitch, Nvidia argues open models and open infrastructure are becoming core to mainstream AI research at ICML 2026, and a new paper says safety outcomes in multi-agent systems can shift dramatically based on deployment rules—not just the model itself. Covered in this episode: - xAI releases Grok 4.5 and positions it as a faster, lower-cost “Opus-class” model - Nvidia says open models and open infrastructure are showing up across ICML 2026 research - A new arXiv paper proposes “institutional red-teaming” for testing deployment rules in multi-agent AI - OpenAI publishes its approach to government and national security partnerships - Paradigm raises a new $1.2 billion fund with AI and robotics in scope - Ashley Smith closes a second $25 million fund for Vermilion Cliffs Ventures Source links: - https://techcrunch.com/2026/07/08/spacexai-releases-grok-4-5-which-elon-describes-as-an-opus-class-model/ - https://blogs.nvidia.com/blog/open-models-icml-2026/ - https://arxiv.org/abs/2607.07695v1 - https://openai.com/index/government-national-security-partnerships - https://techcrunch.com/2026/07/08/crypto-vc-firm-paradigm-raises-1-2b-to-invest-in-technical-frontier-startups/ - https://techcrunch.com/2026/07/08/solo-gp-ashley-smith-announces-25m-close-of-second-fund/
