An xAI generation glitch is turning Grok into a word-salad machine for some users — and the company's own status page still insists nothing is wrong. xAI's Grok chatbot has been replying with pages of incoherent gibberish to a subset of users, with the failures concentrated

Open models just hit a symbolic milestone, Nvidia is engineering a China-compliant chip, and a new Pew study says a third of the post-ChatGPT web was written by AI. Google's Gemma family of open models has surpassed 1 billion downloads, with developers publishing more than 100,

Two moves today point at the same prize: whoever sits between you and the model gets paid. Ramp is building the toll road, while Liquid AI is making the smaller models running on it go faster. Expense-management fintech Ramp just opened its own AI model router, letting developers and

Two US senators have turned one of the year's darkest platform-safety stories into a regulatory deadline: TikTok has until September 1 to explain an experiment that removed a mental-health safeguard for millions of users — including a 16-year-old who later died by suicide. Senators Marsha

Adobe has opened the audio doors on Firefly. The company announced general availability of in-app generators for music, speech, and sound effects, turning its creative AI studio into a one-stop shop for AI-made sound that's pitched as safe for commercial use. The three tools landed

Modular has thrown open the source for Mojo, the systems programming language it built for the AI-accelerator era, releasing the full compiler and toolchain under the Apache 2.0 license (with LLVM exceptions) on GitHub. For a language that spent four years in public development behind a closed compiler,

A new controlled study just gut-checked the cybersecurity scores that frontier labs put in their model cards — and the numbers don't survive contact with a human auditor. A team at security firm Dreadnode ran 22 of the leading AI models against 23 capture-the-flag challenges and

Two moves today show AI shifting from flashy demos to the unglamorous plumbing that actually makes models useful: a retrieval layer that reads inside dense filings, and Tesla quietly pulling humans out of its robotaxis. Mistral's new Agentic Search turns RAG from a single guess into a multi-

A new open-weight model from Google trades the one-word-at-a-time habit that has defined language models for a decade, and a separate wave of harder-to-spot AI fakes is spreading on X. Plus, a Y Combinator startup thinks the key to cheap nuclear power for

A robotics model that learns from one short demo, a confirmed breach at an AI-data giant, and new guardrails for autonomous agents — here's the AI news moving now. Generalist AI's GEN-1.5 teaches robots a new task from a 3- to 12-second demonstration

China's AI labs are closing the book on the "cabbage price" era — the two-year race to give away model inference is reversing, and the bill is arriving fast. Three moves from the last 24 hours show the industry pivoting from land-grab to margin. China&

Three threads from today's feed: collaboration tools are bending toward agents, a founding figure of reinforcement learning is questioning the field's favorite shortcut, and the cybersecurity job market is splitting along an experience line. Slack Code turns chat channels into shared workspaces for coding agents. The
