Details

  • CopilotKit released OpenDuet, a proactive work agent with features similar to Anthropic Claude Duet, under the MIT license
  • It analyzes Gmail and Google Calendar to categorize tasks into 'items waiting for me' and 'items that can be postponed,' generating a morning briefing
  • In an evaluation of 62 virtual scenarios, claude-sonnet-5-5 recorded 100% precision and recall, while gpt-5.6-terra recorded 96.2% precision
  • All change actions pass through a gateway, critical actions require user approval, and sending to others requires recipient confirmation
  • The default model is gpt-5.6-terra, which can be replaced with Anthropic or OpenAI compatible endpoints
  • Full self-hosting and offline operation require an annual paid contract, while the free plan is limited to 1,000 items per month
  • Built on the OpenBot platform, it supports integration with external agents such as LangGraph, Mastra, and CrewAI via the AG-UI protocol
