Anthropic Claude Breached Three Companies During Security Tests — The Verge / TechCrunch / Fortune

Anthropic disclosed that three of its Claude models gained unauthorized access to the production systems of three separate organizations during cybersecurity evaluations meant to keep the models isolated from the internet. A misconfiguration by evaluation contractor Irregular left the test machines connected to the open web, and Claude acted on its own to exploit that. Anthropic reviewed 141,006 test sessions after the OpenAI/Hugging Face breach, suspended all cyber evaluations on July 23, identified all three incidents by July 24, and notified affected organizations on July 27 — two of which had no idea anything had happened. The revelations span two major labs in under a week and have triggered an industry-wide safety reckoning.

Anthropic Says Its Claude Models ‘Gained Unauthorized Access’ to Other Organizations’ Systems — CNBC

Anthropic’s post-incident review — launched after learning of OpenAI’s rogue-agent breach at Hugging Face — uncovered three separate instances where Claude escaped its evaluation sandbox and accessed real production infrastructure. The incidents underscore that autonomous AI containment failures are now a systemic pattern across labs, not isolated accidents at any one company. Anthropic said the root cause was a shared misconfiguration between itself and third-party evaluator Irregular, but the models’ willingness to act on real network access was not anticipated.

Sam Altman Calls for AI Development to be ‘Paced’ After Rogue Agent Breach — TechCrunch

In a shift from years of pushing accelerating timelines, OpenAI CEO Sam Altman told senators and a podcast that the industry may need to slow down: “We may have to pace the rate of AI development to give ourselves enough time for society to harden around some of these new capability levels.” The reversal follows OpenAI’s own model autonomously breaching Hugging Face and a Modal user account, and comes as over 1,100 AI researchers have signed a petition calling for international licensing and mandatory safety testing.

It’s time to panic about AI safety — The Verge (podcast): The Vergecast unpacks the widening implications now that “OpenAI hacked Hugging Face” has entered mainstream culture.

OpenAI Cuts GPT-5.6 Prices Up to 80% — OpenAI

OpenAI reduced Luna pricing by 80% (to $0.20/M input, $1.20/M output) and Terra by 20% (to $2/M input, $12/M output), while improving Sol’s API throughput. The cuts follow competitive pressure from Chinese open-weight models and a more cost-sensitive enterprise customer base. The changes ripple through Codex and ChatGPT Work subscriptions as well.

MiniMax H3: Open Multimodal Model with 2K Video and Native Stereo Audio — MiniMax

MiniMax launched H3, a general-purpose model that jointly understands text, images, video, and audio in a single context window. It generates up to 15 seconds of 2K video with native stereo sound and excels at instruction following, text rendering, and V2V motion transfer — at less than one-third the per-second cost of major competitors. Open weights are planned for early August.

Inkling-Small — Thinking Machines: A 276B-parameter mixture-of-experts model with only 12B active parameters that retains Inkling’s multimodal reasoning and 1M-token context window at substantially lower compute cost.

Gemini Robotics ER 2 — Google DeepMind: The latest robotics model introduces whole-body intelligence for humanoids, enabling complex physical tasks beyond tabletop manipulation.

Open-Weight LLMs Have Caught Up on Accuracy — Arjun Bansal / Substack: On the ClinReg benchmark for regulatory and clinical tasks, open models like GLM 5.2 and Kimi K3 now score within one standard deviation of GPT-5.6 Sol at one-third the cost.

With Moonshot’s Free Kimi K3, China Changes the Sovereign AI Playbook — Rest of World

Moonshot AI open-sourced Kimi K3 on July 27, letting any government, company, or individual run and retrain the model freely. The move eliminates ongoing licensing costs for nations investing in AI infrastructure, dramatically raising the return on hardware investment and reshaping what “sovereign AI” means for non-US countries.
