The high-bandwidth RDMA networks that make modern LLM serving work have confined both prefill and decode to the same datacenter, sometimes even the same rack. A team of researchers at Moonshot AI and Tsinghua University is making the […] The post Moonshot AI..."},{"title":"OpenAI Scales Trusted Access for Cyber Defense With GPT-5.4-Cyber: a Fine-Tuned Model Built for Verified Security Defenders","url":"https://www.marktechpost.com/2026/04/20/openai-scales-trusted-access-for-cyber-defense-with-gpt-5-4-cyber-a-fine-tuned-model-built-for-verified-security-defenders/","source":"MarkTechPost","summary":"OpenAI is moving from a limited pilot to broad deployment of its Trusted Access for Cyber program, introducing GPT-5. 4-Cyber — a variant of GPT-5. 4 fine-tuned to be cyber-permissive — for thousands of vetted defenders."},{"title":"Anthropic walks into the White House and Mythos is the reason Washington let it in","url":"https://www.artificialintelligence-news.com/news/anthropic-mythos-ai-cybersecurity-white-house/","source":"AI News","summary":"When we covered Project Glasswing earlier this month, the story was about a model too dangerous to release publicly and what Anthropic decided to do with it instead. That story has moved. On Friday, Anthropic CEO Dario Amodei walked into the West Wing for a meeting with White House Chief of Staff Susie Wiles."}]}
