Muse Glimmer ✨, OpenAI Cyber 🛡️, Claude vs Riemann Hypothesis 🧠

Anthropic's Claude AI model advanced mathematical research by improving the lower bound of zeros satisfying the Riemann hypothesis from 41.6% to 67.2%, coordinating subagents to verify the result. Meta launched Muse Glimmer, a 30B-parameter open-weight model optimized for local agents and coding tasks. OpenAI released GPT-5.6-Cyber, a model specialized for cybersecurity tasks, expanding its Daybreak program with new access tiers.
