Vercel Chat SDK adds support for Claude Managed Agents
Vercel published a template on August 27, 2026 for running a Slack research bot on Anthropic's Claude Managed Agents through the Chat SDK. It holds one persistent Claude session per Slack thread, streams research briefs with their sources back into the thread, and needs no Slack credentials managed by the app itself.

Anthropic will watermark Claude's text output
Anthropic explained on August 14, 2026 that future Claude models will embed a watermark in generated text, to comply with the EU AI Act. It works by steering the model's choice among equally viable next words using a key plus the preceding words, leaving a pattern readable only with a decryption key. It carries no identifying information and cannot be traced to a user, organization, or conversation, and has minimal effect on code or on heavily edited text. Users cannot opt out; a detection API is planned.
