Claude API gets “message threads”: the server keeps the conversation and each request sends only the new messages
Anthropic launched message threads in beta in the Messages API, enabled with the message-threads-2026-08-12 header. With them, the server stores the conversation history and the program sends only the new messages with each request, instead of resending everything. The thread expires 5 minutes after the last request and is deleted within 1 hour at most. The feature is available on the Claude API, AWS, Google Cloud and Microsoft Foundry.
