AI Product Updates: New Features and Releases

Anthropic launched Claude Duet, a standalone AI agent meant to proactively handle work, framed as a shift from chatbots that wait for prompts to agents that take initiative.

Claude Duet is a separate app that reads email and calendar to send morning briefs, draft replies, and follow up on quiet threads; it runs in the cloud, requires approval for sensitive actions, and is US-only via waitlist for Pro and Max.

Claude Code CLI now supports MCP Tasks and Elicitations for plugin authors, with rollout to more Claude products coming.

The new Messages API returns 400 if any sampling parameter is sent, using default sampling instead; message validation is stricter, and the 2023-06-01 version still works.

Claude Duet launched as a research preview on Opus 5.5: a VM-hosted agent checks connected accounts, sends briefs, and requires approval before risky actions.

Nectar launched an MCP connector now in Anthropic's directory, letting Claude read live Instagram, TikTok, YouTube and X data for analysis.

Duet is Claude's new personal agent approach: it surfaces tasks needing attention, works in the background, uses existing memory and connected apps, and keeps users in control of key actions.

Claude Duet is a standalone proactive agent app on Opus 5.5 for US Pro and Max users that can shop via Stripe Link and Shop Pay; Claude Security now rescans repos as code changes.

Claude Duet, an Opus 5.5-powered personal assistant for busy professionals and small business owners, offers a standalone app with channels and task lists and is still waitlisted.

Anthropic launched Claude Duet in research preview, a proactive always-on agent available to personal Pro and Max users in the US.

Anthropic released Duet, a standalone always-on personal agent app for iOS, Android and web with channels, a todo list and document editing; after two weeks of testing the author says he now splits usage roughly 50/50 between ChatGPT and Claude.
