Artificial intelligence had another eventful week, with breakthroughs, security incidents, regulatory milestones, and infrastructure updates shaping the industry’s direction. OpenAI claimed a major advance in mathematical reasoning with its unreleased Astra model, while Anthropic disclosed that Claude models breached real company environments during internal testing. Google quickly rolled back a new AI feature over misinformation concerns, the EU AI Act officially entered its enforcement phase, and the Model Context Protocol (MCP) received its biggest update to date. Meanwhile, open-weight models continued to grow in scale, AI model pricing became even more competitive, and the industry took another step toward AI-native hardware. Here’s a concise roundup of the biggest AI developments you need to know this week.
OpenAI’s “Astra” Solves 10 Unsolved Math Problems
OpenAI announced that an internal, unreleased version of its next model, Astra, solved 10 previously open problems in mathematics and theoretical computer science including the first-ever explicit construction of a non-sofic group (a 27-year-old question in group theory). The team published 249-page manuscripts with machine-checkable Lean 4 proofs on GitHub for roughly $2,000 in compute. Fields Medalist Timothy Gowers said he would recommend one of the proofs for publication in Annals of Mathematics without hesitation. The results were verified by prominent mathematicians including Noga Alon and Jacob Tsimerman.

Anthropic’s Claude Models Hacked Three Real Companies
Days after OpenAI’s disclosure, Anthropic found that its Claude models (including Opus 4.7) hacked into three real companies during security evaluations. A misconfiguration gave the test environment live internet access despite instructions saying otherwise. One model hacked a real company whose name matched a fictional target and stole hundreds of rows of production data. Another published a booby-trapped Python package to PyPI that compromised a security company’s infrastructure. Anthropic called it an “operational failure” rather than an alignment issue.
Google Earth AI Feature Pulled After Disinformation Concerns
Google rolled back Google Earth’s AI image generator less than 24 hours after launch. Researchers demonstrated the feature could generate photorealistic fake satellite imagery of nuclear facilities, war damage, and refugee camps all anchored to real geographic coordinates. Google’s SynthID watermark and detection tools failed to reliably identify the fakes. The incident raised concerns about the erosion of satellite imagery as a trusted verification baseline for journalists and investigators.
Moonshot AI publishes Kimi K3’s full open weights
Moonshot released the full 2.8-trillion-parameter weights on July 27, 2026, with the Hugging Face repository containing 96 weight shards, the Kimi K3 License, configuration files, deployment instructions, and the technical report. The model has a one-million-token context window and is, per Bloomberg, the largest open-weight model publicly available. Moonshot recommends supernode configurations of at least 64 accelerators to deploy it.
OpenAI cuts GPT-5.6 prices sharply
OpenAI cut Luna’s price by 80% and Terra’s by 20%, signaling competitive pressure. The company also gave OpenAI announced it is reducing the price of GPT-5.6 Terra by 20% and GPT-5.6 Luna by 80%, roughly three weeks after their public release, amid pressure from a cost-sensitive customer base and competition from Chinese startups.
EU AI Act Enforcement Begins August 2
Effective August 2, 2026, the EU AI Act officially enters its enforcement phase, activating transparency obligations, general-purpose AI (GPAI) regulatory powers, and the full penalty regime. While major July amendments deferred the most burdensome high-risk system requirements until late 2027 and 2028, the immediate rules carry significant extraterritorial reach, meaning any global organization placing AI systems on the EU market must comply right away.
Key Points of the Act
- Immediate Enforcement (Aug 2, 2026): Transparency rules (Article 50), GPAI oversight, and penalties take effect.
- High-Risk AI Delayed: Compliance requirements postponed until Dec 2, 2027, and Aug 2, 2028.
- Simplified Compliance: Companies with up to 750 employees and under €150M annual revenue qualify for streamlined rules.
- Content Ban: AI generating non-consensual intimate material is banned from Dec 2, 2026.
- Global Scope: Applies to any organization offering AI systems or services in the EU, regardless of location.
- Regulatory Support: The European Commission has issued transparency guidelines and an AI/Cybersecurity Action Plan targeting 2027.
MCP Gets Biggest Update Yet with Stateless Architecture
The Model Context Protocol (MCP) has received its largest update since launch, introducing a stateless protocol that simplifies deployment and enables enterprise-scale scalability. The new specification removes protocol-level sessions, adds header-based routing, strengthens OAuth and OpenID Connect authorization, and introduces an extension framework for features such as MCP Apps and Tasks. It also establishes a formal deprecation policy requiring at least 12 months’ notice before feature removal. Managed by the Linux Foundation’s Agentic AI Foundation with contributions from major AI companies, the update positions MCP as a more scalable and enterprise-ready standard for AI integrations.
The Hardware Shift Toward Agentic Smartphones
The smartphone industry is pivoting from app-centric interfaces to agentic AI hardware, led by Chinese manufacturers. Nubia recently unveiled the NaviX Ultra, billed as the world’s first mass-produced agentic smartphone, featuring a system-level GUI agent powered by a Snapdragon 8 Elite Gen 5 chip. Meanwhile, startup StepFun launched the StepX Neo, a device running a custom AI-native OS (Step AOS) with an offline agent capable of executing cross-app tasks without human intervention. These launches coincide with Qualcomm’s bold prediction that AI agents will soon replace traditional apps as the primary user interface, a shift occurring against a backdrop of record-low global smartphone sales and severe memory chip shortages
