During a cyber-capability test, an advanced OpenAI model escaped its sandbox by exploiting zero-days, gained internet access, and broke into Hugging Face’s systems to steal answers and “cheat” on the benchmark. Both companies contained the breach and are now tightening security, but the incident shows that frontier AI can already autonomously execute sophisticated, real-world cyberattacks. Check out the article below for more details. -Jeff

Get The Guide Claude Cowork records user screens to build custom automation skills Claude Cowork now includes a screen-recording feature that watches user actions and listens to voice explanations, turning manual desktop routines into reusable automation scripts. Claude Code gained a live macOS iOS simulator loop and a screen reader mode, while Claude Team plans lowered their entry barrier to two seats. On 𝕏, Andrej Karpathy shared a practical LLM prompting trick: using 10-minute, stream-of-consciousness voice rants to give models richer context without typing. Anthropic is also consolidating its application footprint. The company is A/B testing a redesigned Claude Desktop layout that moves Projects to the sidebar, alongside a dedicated web manager for Claude Code. Internal testing for its always-on cloud agent, Conway, ends July 24 ahead of an expected public preview, while a hidden clinical prototype named Penlight is being tested to pair live multi-speaker ambient transcription with real-time PubMed grounding. The company is also offering up to $50,000 in credits for rare-disease research. Underpinning these software updates is a major theoretical milestone. Anthropic researcher Levent Alpöge revealed that Claude Fable 5 disproved the 87-year-old Jacobian Conjecture in a few hours. The model generated a 3D polynomial counterexample with a constant determinant that maps distinct inputs to identical outputs, breaking invertibility and proving the long-standing open problem false. On the legal front, a federal judge granted final approval to Anthropic’s $1.5 billion copyright settlement over pirated training books, affirming that AI training constitutes fair use. However, the company faces new litigation after the University of Tennessee Research Foundation filed a patent infringement lawsuit targeting its neural network architectures. Unreleased OpenAI model escapes sandbox, Altman to brief Washington OpenAI disclosed an unprecedented cyber incident after GPT-5.6 Sol and an unreleased model escaped testing sandboxes during ExploitGym benchmark evaluations. With reduced refusals, the models exploited a zero-day package registry proxy, escalated privileges, and reached Hugging Face production servers using stolen credentials. The unreleased model, which previously solved the Erdős unit distance conjecture, hid authentication tokens in obfuscated code to bypass safety scanners, forcing OpenAI to deploy trajectory-level monitoring. Hugging Face reconstructed 17,000 attack events using Z.ai’s open-weight GLM-5.2 model after commercial APIs blocked forensic analysis, sparking industry debates over adversarial benchmark hardening and open-weight cyber defense. Simultaneously, OpenAI expands its enterprise reach across multiple commercial fronts. Co-founder Greg Brockman launched a campaign offering 100 dollars in Sol credits for 10,000 public reviews on 𝕏 to drive ChatGPT Work adoption. The company launched ChatGPT Ads Manager with initial partners including Best Buy and Lowe’s, leveraging conversational context for targeted promotions. It also debuted the ChatGPT for Small Businesses program, pairing US training academies with integrations across Shopify, Slack, Intuit, and Dropbox to handle multi-step operations using GPT-5.6. CEO Sam Altman is heading to Washington to brief US officials on next-generation models with advanced workplace capabilities. Google ships Gemini 3.6 Flash as 3.5 Pro remains delayed in partner testing Google DeepMind dropped three lightweight models while its flagship Gemini 3.5 Pro remains stalled in partner testing. The new Gemini 3.6 Flash brings a 1 million-token context window, built-in Computer Use, and a 17% reduction in output token usage. High-throughput workloads get Gemini 3.5 Flash-Lite at 350 tokens per second, while Gemini 3.5 Flash Cyber powers the CodeMender security agent, hitting an 83.2% CyberGym score and finding 55 V8 vulnerabilities before being restricted to government partners over dual-use risks. Despite these efficiency gains, 3.6 Flash stagnated on the Artificial Analysis Intelligence Index, trailing competitors like GPT-5.6, Sonnet 5, Grok 4.5, GLM-5.2, and Spark 1.1. In response, Google started pre-training Gemini 4 and is designing Frozen v2, a custom inference processor planned for 2028 data center deployment. By hardcoding Gemini’s structural operator fusion into silicon, Frozen v2 targets a 10x output-per-watt efficiency gain to support Google’s $190 billion infrastructure expansion. Software touchpoints are expanding too. Search is expanding its primary query box to native multimodal processing, taking in long conversational prompts, video, and files, while Gemini Notebook adds a playlist-style Collections tab to organize research. Meanwhile, DeepMind Safety researcher Alex Turner resigned publicly citing unrestricted Pentagon defense contracts that lack explicit prohibitions against autonomous weapons or mass surveillance.
