Anthropic: Message Threads cuts time to first token by 35 percent in long conversations

Anthropic has made Message Threads publicly available in beta on Claude; the feature sends only conversation changes and, according to the company, cuts the wait for a first token by about 35 percent for requests from 500,000 to one million tokens.

The company says Message Threads is most useful for coding and computer-use agents, as well as workflows that process many documents or images. Token usage remains unchanged because Claude still reads the entire conversation history.
