By PulseAugur Editorial · [1 sources] ·

Anthropic has launched Claude Duet, a proactive AI agent for iOS, Android, and claude.ai, built on Claude Opus 5.5. Duet proactively checks connected accounts for updates, such as new shop openings without health permits, and can draft necessary documentation. It operates with a virtual machine and over 6,000 connectors, requiring user approval before taking actions like payments. Concurrently, Recursive released Flint, a compact 40B parameter mixture-of-experts model developed by AI agents in under four months. Flint achieves high speeds on laptops and leads in benchmarks for models under 50B parameters, with its weights available under Apache 2.0. AI

IMPACT These releases highlight advancements in proactive AI agents and efficient, AI-developed models, potentially accelerating automation and on-device AI capabilities.
