July 28
Anthropic publicly defines its position on open-weight models — the same day Nvidia leads an industry-wide AI safety alliance that Anthropic itself, OpenAI, and Google were left out of.

Dario Amodei pushes back: "Anthropic has never advocated banning open-weight models" Critical
In a post signed by its CEO, Anthropic said it has never advocated banning open-weight models, responding to accusations made after a pro-open-weights letter signed by Nvidia, Microsoft, and others. Amodei proposes three concrete measures: blocking the sale of advanced chips to China, fighting industrial-scale distillation operations, and requiring mandatory safety testing for every sufficiently capable model, open or closed.
The post dominated the day's discussion on Reddit — multiple threads racked up hundreds to over a thousand upvotes on r/LocalLLaMA and r/singularity — putting Anthropic back at the center of the US-China debate over open AI.
A broad ban on open models is unlikely in the near term — those building on open weights gain regulatory predictability, but should prepare for mandatory "safety testing" requirements.
Trump administration to ban new Chinese humanoid robots and inverters High
The FCC will announce a ban on imports of new Chinese humanoid and quadruped robot models — hitting Unitree, an Nvidia partner — and Chinese power inverters, citing risks to the US AI supply chain.
It's a direct escalation of the US-China tech rivalry with tangible impact on AI-embedded robotics, one of the hottest sectors of 2026.
Non-Chinese robotics makers (US, Korea, Japan) gain an immediate competitive edge in the American market.
UK lawmaker seeks court order against Grok over sexual deepfakes High
Labour MP Jess Asato filed a claim with London's High Court to stop Grok from generating non-consensual sexualized images of her, alleging misconduct in the model's design and training.
It intensifies global regulatory pressure on xAI, which already faces a lawsuit filed by the city of Baltimore and filed its own suit against a user over CSAM in July.
Companies with AI image generation should get ahead of stricter guardrail requirements against non-consensual deepfakes before regulation arrives first.
[UPDATE] Nvidia leads a 37-company alliance for open AI security — and leaves OpenAI, Google, and Anthropic out Critical
Nvidia formed the "Open Secure AI Alliance" with Adobe, CrowdStrike, Hugging Face, Dell, and 33 other companies to develop and share open AI safety and cybersecurity tools — a direct follow-up to the Hugging Face breach by an OpenAI agent, which Radar IA covered on 07/25.
It's the industry's first coordinated, concrete response to the incident — and the notable absences say as much as the presences: OpenAI, Google, and Anthropic were left out.
Nvidia contributed the open-source "Object-Oriented Agent" project on GitHub to monitor AI agent behavior — worth watching if you build autonomous agents.
Amazon winds down most of its Nova models, bets it all on a frontier model High
According to Business Insider (via Reuters), Amazon is discontinuing most of its flagship Nova models — Premier, Omni, the Reel video generator, and the Canvas image generator — redirecting resources to a new frontier model led by researcher Pieter Abbeel, expected to debut at re:Invent.
It shows the world's largest cloud provider failed to gain traction with incremental models and is now resetting its AI strategy, days after cutting jobs in its AGI group.
Companies relying on AWS for AI should watch this year's re:Invent closely — specific Nova models currently in production could be discontinued.
Meta and BlackRock strike $14B partnership for a Texas AI data center High
Meta and BlackRock announced a joint venture to develop and operate a 1-gigawatt data center campus in El Paso, Texas, with development costs of around $14 billion.
It's another signal of the multibillion-dollar race for AI compute infrastructure, with traditional asset managers now directly funding capacity.
Energy, construction, and electrical equipment suppliers in the Texas region have an immediate business window with this kind of investment.
Nvidia's CDS spikes to a record high amid Chinese chip advances Medium
Nvidia's 5-year credit default swap contracts rose to 82 points, a record level, as AI stocks pulled back following news of Chinese chip advances.
It's a barometer of financial-market jitters over risk concentration in the "AI bubble" sitting on a handful of companies.
Worth monitoring Nvidia's CDS as a leading indicator of sector stress ahead of investment decisions tied to the AI supply chain.
