xAI has launched Grok 4.5, positioning it as a cost-efficient alternative to top-tier models like Claude Opus. Here's what builders need to know about where it fits in the current landscape.
An AI agent executed the technical steps of a real ransomware attack, but a human operator picked the target, built the infrastructure, and handed over stolen credentials. That distinction matters enormously.
Vercel CEO Guillermo Rauch argues that serious AI deployments require separating the model layer from agent logic — because price-performance optimization demands flexibility, not lock-in.
Amazon has stopped accepting new customers for Mechanical Turk, signaling the end of an era for the crowdsourced human-labeling platform that underpinned a generation of AI training pipelines.
Meta's CEO told staff internally that AI agent development isn't moving as fast as expected — a rare public signal of friction inside one of the best-funded AI programs in the world.
Researchers found that feeding an LLM a false arithmetic claim—like asserting 2+2=5—can be enough to bypass its safety instructions. It's a concrete reminder of why giving AI agents browser-level autonomy is still a dangerous proposition.
A widely-discussed GitHub issue suggests that reasoning-token clustering in GPT-4.5 Codex may be causing measurable performance regressions. Here's what's happening and what developers should watch for.
Founded in 2023 and backed by substantial venture funding, Mistral AI has built a credible alternative to closed AI labs by releasing capable open-weight models alongside commercial offerings.
Mistral's Leanstral 1.5 focuses on generating formal proofs in Lean, aiming to make machine-verified mathematics more accessible to developers and researchers.
A benchmark of GLM-5.2 running on AMD's MI355X reports 2,626 tokens per second per node while claiming more than 2x lower cost than an equivalent Nvidia Blackwell setup — a signal that AMD is becoming a real inference option.
GitHub has added Kimi K2.7 Code to Copilot's roster of selectable models, giving developers another coding-focused engine to route their tasks through—no longer a preview or waitlist.
Cloudflare is forcing AI companies to distinguish training and agent crawlers from search indexers — or face automatic blocking across a large share of the web.
