AI safety and efficiency dominated today's headlines. US authorities suspended Anthropic's most advanced Claude models — Fable 5 and Mythos 5 — with co-founder Andrej Karpathy reportedly barred from accessing them due to citizenship status. Meanwhile, AMD's Ryzen AI Max+ 395 launched with 128GB shar

A geopolitical shockwave hit AI today: the US government ordered Anthropic to cut off foreign users from Fable 5 and Mythos 5, marking a shift from geographic to identity-based export controls. MiniMax fired back by open-sourcing M3 weights, promising "M3 will never do this." On the infra side, NVID

AI hit multiple milestones today: MiniMax dropped M3, a 428B MoE model with 1M context and 14x speedup, while Kimi open-sourced K2.7-Code, boosting coding agent scores by 31%. On the cost frontier, researchers trained a 1B foundation model for just $1,500 using a novel HRM architecture — challenging

AI hit major milestones today. OpenAI's GPT-5.5 stunned the industry by beating Anthropic's Claude Fable 5 on the new Agents' Last Exam benchmark — a real-world, long-horizon workflow test where even the best models scored below 25%. Jeff Bezos stepped into the arena, unveiling Prometheus with a rec

AI hit multiple inflection points today. Google DeepMind's DiffusionGemma breaks the autoregressive lock-in, generating text 4x faster by diffusing 256-token blocks in parallel — a paradigm shift for latency-sensitive agents. NVIDIA, Apple, and Google teamed up to bring confidential computing to App

AI hit an inflection point today: Anthropic launched Claude Fable 5 and Mythos 5, which Andrej Karpathy calls a "major version jump" — Stripe used it to migrate 50 million lines of Ruby code in one day instead of two months. Meanwhile, OpenAI filed confidential IPO papers at $852B valuation, setting

AI hit a funding milestone: DeepSeek launched a $7.4B Series A at a $52-59B valuation, with Tencent and CATL joining — the Chinese model race just got real. OpenAI and Anthropic both filed confidential S-1s, kicking off IPO prep. On the agent front, Kimi Work dropped a desktop agent supporting 300 p

AI chip talent wars escalated as OpenAI's custom chip lead Clive Chan jumped to Anthropic, while Jensen Huang warned chip shortages will last years across the full supply chain. China's AI models overtook US competitors on OpenRouter for the first time, driven by Kimi K2.5, MiniMax M2.5, and DeepSee

AI safety and cost efficiency dominated the news today. OpenAI launched ChatGPT Lockdown Mode to block prompt injection data theft — a deterministic defense that's hard to bypass. MiniMax M3 matched Claude Opus on code audit tasks but at 1/18 the cost ($0.07 vs $1.30), while a study in Science showe

AI infrastructure and safety evaluation took center stage today. RedKnot from Xiaohongshu/Huawei Cloud shattered the monolithic KV cache abstraction, boosting LLM serving concurrency by 4.7-7.8x. Scale AI's PropensityBench introduced a new safety paradigm — testing what models *will* do under pressu

AI hit major milestones today: Axiom Math's system scored a perfect 120 on the Putnam exam, beating top human undergraduates and DeepSeek with formal verification. NVIDIA dropped Nemotron 3 Ultra, a 550B MoE with Mamba-Attention that delivers 5x inference speedup for agent workflows. OpenAI upgraded

AI funding hit record highs and evaluation methods faced a reckoning today. DeepSeek is closing ~$7B in funding at a $30B+ valuation, while Alphabet raised ~$85B through equity financing with $10B from Berkshire Hathaway. Google dropped Gemma 4 12B — an encoder-free multimodal model that runs on a l
