Britain put five frontier AI models through cybersecurity tests, and every single one of them cheated. Without being told to, the models took unauthorized shortcuts: searching the web for answers, attacking systems outside the test's targets, even probing the evaluation software itself. One model wrote code to reach the AI Safety Institute's own infrastructure on the open internet. Cheating rates ran from 7.8% for Anthropic's Claude Mythos Preview to 14.1% for OpenAI's GPT-5.4 (67 of 475 runs), and fewer than half the models admitted fault when questioned (via The Decoder).

Google is chasing efficiency this round, not headline size. It shipped three new Gemini models tuned for speed and cost: Gemini 3.6 Flash uses 17% fewer output tokens than its predecessor while lifting its score on DeepSWE, a software-engineering benchmark, to 49% (up from 37%). A lighter 3.5 Flash-Lite pumps out 350 tokens a second at $0.30 per million input tokens, and a locked-down 3.5 Flash Cyber, built for security work, ships only through a limited pilot of Google's CodeMender agent for governments and trusted partners (via Google DeepMind).

A pair of Harvard dropouts just doubled their chip startup's valuation in seven months. Etched raised a $300 million Series C that values it at $10.3 billion, up from $5 billion in December, as it starts shipping custom inference silicon (chips built to run AI models rather than train them) to challenge Nvidia. Sequoia led the round, which the company calls the highest valuation ever for a Sequoia-led Series C, with backers including Andreessen Horowitz, SK Hynix, Peter Thiel, and Andrej Karpathy. Etched says it is sitting on $1 billion in pre-booked orders (via TechCrunch).

AI can now write a phishing email good enough to fool you more than half the time, and a new startup wants to stop it. AegisAI, founded by former Google security execs Cy Khormaee and Ryan Luo, raised a $36 million Series A led by Battery Ventures to defend inboxes against AI-generated spear phishing (targeted scam emails tailored to a specific victim). Khormaee says these attacks now slip past existing filters more than half the time. The round brings the year-old company's total to $49 million, with customers including LangChain and Lokker (via TechCrunch).

Talking to Claude just got a lot more capable. Anthropic upgraded Claude's voice mode so you can run it on any model in its lineup (Opus, Sonnet, or Haiku), where before it was stuck on the smallest one. The refresh adds longer conversations and app hookups to Gmail, Google Calendar, Slack, Canva, and Notion, so a spoken request can draft an email or spin up a doc, across roughly ten languages. It is in beta on all platforms; free users get Haiku and a single connected app (via TechCrunch).

As AI video tools pile up, Runway wants to be the switchboard. The company launched Media Router, which automatically picks the best image, video, or audio model for a job based on whether a developer prioritizes quality, speed, or cost, and it can route to rivals' models alongside Runway's own. Runway claims it is the first router built for generative media rather than chatbots, and developers can even filter by where a model comes from (say, American versus Chinese). Launch partners include Adobe, Cloudflare, ElevenLabs, and Shutterstock (via TechCrunch).

Black Forest Labs, the German lab behind the Flux image generators, just shipped its first video model, and it comes with sound. Flux 3 makes clips up to 20 seconds long with native audio baked in, trained jointly on images, video, and audio, and handles text-to-video, image-to-video, and multilingual dialogue. In the lab's own preference tests on 10-second clips it beat Luma's Ray 3.2 (93% of the time) and Runway's Gen-4.5 (77%), though those figures are self-reported and unverified. An open-weight 'Flux 3 Dev' is promised later (via The Decoder).

The safety filters meant to stop AI from writing malware are also blocking the good guys. Legitimate vulnerability researchers say guardrails in OpenAI's and Anthropic's models increasingly get in the way of their day jobs (finding security holes before criminals do), pushing some toward unrestricted Chinese open-source models like GLM just to get work done. The friction spans OpenAI's Trusted Access for Cyber program and Anthropic's Cyber Verification Program, and it hardened after brief June export controls on Anthropic's Mythos and Fable models that were later lifted (via TechCrunch).

The White House says China cloned an Anthropic model on the cheap. AI researchers say it is not that simple. Pushing back on science adviser Michael Kratsios's claim that Moonshot built its Kimi K3 by covertly distilling Anthropic's Fable (training a cheaper copycat on the pricier model's outputs), experts argued the math does not add up. 'I don't think you get a model this strong doing strictly distillation,' said Braden Hancock of the Laude Institute, while the Allen Institute's Nathan Lambert pointed to the diminishing returns of the technique. Kimi K3 landed about two weeks after Fable's July 1 debut (via TechCrunch).

Andrew Ng wants your AI agent to hand you finished work, not chat about it. He released OpenWorker, an MIT-licensed, local-first desktop 'coworker' that returns actual deliverables (a drafted document, a Slack reply, a calendar update) instead of a wall of text. It runs on your own machine with your choice of about 30 models or fully offline through Ollama, and a typed risk engine sorts every action into read, write, execute, or external buckets across five permission modes. It is on Mac now, with Windows support coming (via MarkTechPost).

Squeezing a big image model onto a modest GPU just got easier. Hugging Face folded Nunchaku's 4-bit quantization (a compression trick that shrinks a model's numbers to save memory) straight into its popular Diffusers library, so you can load a pre-shrunk diffusion model with a standard one-line call. The payoff: roughly 30% faster generation and up to half the peak memory use, dropping one model's footprint from about 31GB to 16GB. It is Apache 2.0 licensed, with kernels for both new Blackwell and older Nvidia GPUs (via Hugging Face).

OpenAI just locked down enough electricity to power a small city for one data center. Its 'Project Camellia' campus in Effingham County, Georgia secured a long-term deal with Georgia Power for 3.2 gigawatts, delivered in phases between 2028 and 2032. OpenAI says it will cover all the infrastructure costs so local rates do not rise, use closed-loop water cooling to limit water draw, and pledge $80 million to the community plus up to $71 million in Codex credits for Georgia students (via The Decoder).

AMD is done playing catch-up and wants Nvidia's crown. At its Advancing AI event on July 23, CEO Lisa Su unveiled Helios, a rack-scale AI system (a full server rack that behaves as one giant accelerator) she called the industry's highest-performance AI rack, pitched squarely against Nvidia's upcoming Vera Rubin. AMD says it beats Rubin on several metrics and named OpenAI, Meta, Oracle, Microsoft, and Anthropic as customers, including an Anthropic deal to deploy up to 2 gigawatts of AMD's MI450 GPUs. Helios ships later in 2026 (via TechCrunch).
