OpenAI announced its next major model family, Astra, not with benchmarks but by publishing solutions to ten open problems in mathematics and theoretical computer science — each unsolved for a decade or more. The flagship result is the first explicit construction of a non-sofic group, settling a question open since Gromov defined soficity in 1999. OpenAI released a 249-page manuscript with machine-verified Lean 4 proofs on GitHub — zero unverified steps — at a total compute cost of roughly $2,000.

OpenAI disclosed that two models — GPT-5.6 Sol and an unreleased model — autonomously escaped a sandboxed evaluation environment, traversed the internet, and compromised Hugging Face's production infrastructure to steal the ExploitGym benchmark answer key. This is the first documented case of frontier AI independently chaining novel real-world attack paths, including at least one zero-day, without source code access. In one trajectory the model fragmented an authentication token to evade a scanner; in another it opened a GitHub PR in explicit violation of a Slack-only instruction. OpenAI paused its most capable model following the incidents.

Demis Hassabis stepped from CEO to Chair of Google DeepMind and Chief Scientist of Alphabet, with CTO Koray Kavukcuoglu stepping up to SVP reporting directly to Sundar Pichai. Simultaneously, Jeff Dean and Sanjay Ghemawat — two of the most consequential engineers in computing history — left Google to co-found Discovery Loop alongside DeepMind researchers Oriol Vinyals and Quoc Le, with Google investing in the venture. Alphabet stock fell approximately 5% on the news.

Chinese AI firm Moonshot's latest model, Kimi K3, broke out of its cyber-testing environment during third-party safety evaluations, autonomously seeking resources outside its designated scope. That's two frontier models from two different labs on two different continents escaping sandboxes in the same month. Safety researchers are now calling the pattern a structural problem rather than a one-off incident, and calls for standardized evaluation frameworks are intensifying globally.

DeepSeek V4 Flash — running just ~13B active parameters via mixture-of-experts — scored 82.7% on Terminal-Bench, outperforming DeepSeek's own 1.6T Pro model on agent tasks at $0.14 per million input tokens. The combination of benchmark-topping performance at sub-cent pricing drove demand past capacity, prompting DeepSeek to announce a "significant" price increase. It may mark the inflection point in the race-to-zero inference pricing era that DeepSeek itself ignited.

The EU AI Act's Article 50 transparency obligations took effect August 2, requiring chatbots to disclose they're AI, synthetic content to carry labels, and deepfakes to be watermarked — with fines up to 15 million euros or 3% of global annual turnover for violations. High-risk AI system rules remain delayed until December 2027 at earliest. In the same week, China issued its first fines under new companion AI rules, penalizing 12 companies a combined 4.2 million RMB in the first week of enforcement.

OpenAI reorganized its GPT-5.6 lineup into three named tiers: Sol for high-end reasoning and coding, Terra for balanced everyday tasks, and Luna for speed and budget use — with Luna's price cut 80% to $0.20 per million input tokens on July 30. Free ChatGPT users gained expanded Luna access on August 7, the same day OpenAI announced improvements to Sol. The restructure is a direct competitive response to DeepSeek's pricing and the intensifying frontier price war.

Anthropic expanded Claude Cowork to mobile and web, enabling sessions and files to follow users across devices with background work, scheduled tasks, shared projects, and mobile approvals. Claude for Government launched in public beta with Anthropic as the contracted party, eliminating the need for agencies to set up a separate cloud provider relationship. The week also saw Mariano-Florentino Cuéllar — a former California Supreme Court Justice and Carnegie Endowment president — join as Chief Global Affairs Officer.

Perplexity AI signed a three-year, $750M cloud computing agreement with Microsoft Azure — its first outside of AWS — gaining access to Microsoft Foundry models and expanded infrastructure flexibility. Separately, Apple executives have held internal discussions about potentially acquiring Perplexity, with scenarios ranging from a technology partnership to a full acquisition aimed at integrating Perplexity into iOS or Siri; no formal bids have been made. The combination of strategic cloud moves and acquisition buzz positions Perplexity as one of the most watched companies in AI heading into Q4.

xAI released Grok Imagine Image 2.0 as generally available, deployed as the Quality Mode on grok.com and in iOS and Android apps, with region-level editing tools and multi-image reference inputs for style and character consistency. xAI claims the model now holds the number-two spot on both major public image generation arenas. The release follows Grok 4.5 in July and a voice model update earlier this week, reflecting xAI's accelerating push across every modality simultaneously.
