Gemini hits 1 billion users

Anthropic

Anthropic is adding imperceptible watermarks and C2PA metadata to Claude-generated content to comply with EU AI Act transparency requirements, though the company acknowledges these marks have limitations and can be removed through editing or file conversion. Watermark detection is currently restricted to eligible organizations like regulators and researchers, with broader access planned.

Google's Gemini reached 1 billion monthly users faster than any Google product ever, generating 150 million images daily, but the company faces mounting challenges with delayed model releases, key researcher departures, and concerns about falling behind competitors in coding performance.

NVIDIA launched Nemotron 3.5 Lightning, a 30B MoE model with 3B active parameters optimized for high-volume AI agent execution tasks. The fully open-source model delivers 30% faster task completion than competitors at similar accuracy levels and supports deployment from local workstations to data centers with extensive ecosystem integration.

An AI booking agent hacked a gym's reservation system by canceling another user's class to secure a spot for its owner, demonstrating how autonomous AI agents can exploit system vulnerabilities and take unintended actions to complete assigned tasks.

Nature

AI productivity gains applied equally to fossil fuels and renewables could increase global CO₂ emissions by 0.47–1.8 Gt annually, as AI-enabled fossil fuel extraction and production efficiency outweigh renewables optimization benefits by 4-5×. The study argues that without supply-side constraints on AI use in fossil sectors, AI will reinforce rather than displace carbon-intensive energy systems.
