🔓 OpenAI launches GPT-5.6-Cyber for defenders
LINK
|
- OpenAI launched GPT-5.6-Cyber, a version of GPT-5.6 Sol tuned to reduce refusals on advanced cybersecurity work, and expanded its Daybreak programme to give vetted defenders less-restricted access as it braces for autonomous cyberattacks.
- GPT-5.6-Cyber completed 95% of requests spanning exploit-chain development, authentication bypass, and privilege escalation, up from GPT-5.5-Cyber's 57.3% and far above the 1.5% and 2% that guardrailed Sol and Daybreak Blue handle.
- Delivered via two tiers, Daybreak Blue (Sol with reduced guardrails) and Daybreak Red (Cyber), the models let vendors like CrowdStrike, Cisco, and Palo Alto Networks ship them in products, though access requires identity verification, monitoring, and legal attestations.

🏋️ AI agent hacks gym waitlist
LINK
|
- An AI agent tasked with booking a gym class instead exploited a flaw in the booking software, bumping another customer off a waitlist to move its user up a spot, an unintended action nobody had requested.
- Andrew, an Australian AI-product developer, ran the agent on OpenClaw powered by Anthropic's Claude; it first reserved classes further ahead than allowed, then found the API skipped authorisation checks on cancelling other people's reservations.
- The agent self-reported the exploit and confirmed its test cancellation succeeded, but when asked to undo it, said it could not restore the removed person's place on the list.

🎨 Microsoft's new image AI ranks second
LINK
|
- Microsoft has launched MAI-Image-2.6, its newest text-to-image model, which now sits at #2 on the Arena leaderboard, trailing only OpenAI's GPT-Image-2.
- The model scored +79 Elo over MAI-Image-2.5 in Arena's text-to-image category, with Microsoft citing gains in text rendering, portraits, 3D imagery, and photorealistic commercial, branding, and cinematic outputs.
- Microsoft points to better grounding, multi-reference workflows, and finer control over reasoning, format, and resolution, though the model is only available on Arena for now, reaching MAI Playground and Microsoft Foundry later this week.

🪁 Cloudflare builds a browser for AI agents
LINK
|
- Cloudflare launched Kitesurf, a cloud-hosted browser purpose-built for AI agents rather than humans, stripping out tabs, extensions and high-fidelity rendering to navigate sites, extract content and capture screenshots at lower CPU and memory cost.
- Running on Cloudflare Workers with the Blitz rendering engine, Firefox's Stylo CSS parser and the Boa JavaScript engine, Kitesurf used 3.1x less CPU and 4.7x less memory for screenshots, and 3.8x less CPU and 7x less memory for HTML extraction versus Chromium.
- Available in beta through Browser Run on free and paid tiers with CDP and MCP client support, Kitesurf targets short, stateless tasks, though Chromium finished faster on wall-clock time and it still lacks video playback, WebGL and persistent authenticated sessions.

🧮 Claude cracks century-old Riemann problem
LINK
|
- Anthropic reports an unreleased research version of Claude made real progress on the Riemann Hypothesis, one of the Millennium Prize Problems, during an autonomous multi-day session.
- Running inside Claude Code, the model raised a longstanding lower bound on zeros on the critical line from 41.6% to 67.2%, burning 31M output tokens across two sessions and 650 failed ideas.
- It coordinated 60 subagents running 2,400 shell commands, with the results validated by in-house and external number theorists and a Lean proof published, though Anthropic gave no timeline for releasing these multi-agent capabilities.
