The feature lets developers send only new messages in long-running agent sessions—such as coding or document-heavy workflows—reducing median latency for large requests (500,000 to 1 million tokens) by about **35%** by avoiding full-conversation re-uploads on each turn.\n\nThreads work by splitting requests into **create** (full conversation) and **continue** (new messages only) steps. They expire after **five minutes** of inactivity and are stored in memory under server encryption, deleted within **one hour**. Developers must handle their own conversation history since there’s no API to retrieve or delete threads. The beta excludes organizations with **Inference hooks**, **Message Batches**, or **zero-data-retention** requirements. Anthropic’s SDK simplifies thread management but does not auto-retry failed continues or cache prompts—developers must manually implement caching and error handling.","keyPoints":["Message threads cut latency by 35% for large requests (500K–1M tokens) by skipping full-conversation re-uploads","Beta available on Claude Platform, AWS, Microsoft Foundry, and Google Cloud with all models enabled","Threads expire in 5 minutes, require manual conversation history backup, and exclude HIPAA/zero-retention use"],"whyItMatters":"Faster agent responses lower costs for long-running tasks like coding or document processing, but memory-only storage and manual backups add operational complexity for developers.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["Anthropic"],"models":["Claude","Claude Code"],"people":[]},"firstPublishedAt":"2026-11-02T19:21:04Z","updatedAt":"2026-11-02T19:21:04Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"Unite.AI","title":"Anthropic Launches Message Threads Beta for Long-Running Agents","url":"https://unite.ai/anthropic-launches-message-threads-beta-for-long-running-agents","publishedAt":"2026-11-02T19:21:04Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"Anthropic AI Saga Claude Duet Attack Failures","url":"https://digestai.news/thread/anthropic-launches-claude-duet-a-proactive-ai-assistant-for-us-paid-users","storyCount":3},"cite":{"text":"Digest AI, \"Anthropic adds message threads to Claude Platform for faster agent responses\", 2 November 2026, https://digestai.news/story/anthropic-adds-message-threads-to-claude-platform-for-faster-agent-res","publisher":"Digest AI","title":"Anthropic adds message threads to Claude Platform for faster agent responses","datePublished":"2026-11-02T19:21:04Z","url":"https://digestai.news/story/anthropic-adds-message-threads-to-claude-platform-for-faster-agent-res"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
