AI guide
Claude Platform has launched a public beta for message threads in the Messages API. Long-horizon agents no longer need to resend the entire conversation history in each turn; transmitting only incremental messages significantly reduces time-to-first-token (TTFT).
Why it matters
By resolving the latency overhead caused by repeatedly transmitting massive historical context in extended conversations, this feature offers an immediate optimization for coding agents that rely heavily on multi-turn calls.
