Anthropic has launched a beta for 'Message Threads' in the Claude Messages API, allowing the server to cache conversation context so developers no longer need to resend full history each turn. This feature significantly reduces request payload size (from ~800KB to 1.8KB) and cuts time-to-first-token by ~35%, though token pricing remains unchanged. It is particularly beneficial for long-running agents and multimodal interactions.

    Claude API Launches Message Threads Beta to Speed Up Long Conversations

    • Server-side context caching reduces median request size from 800KB to 1.8KB and cuts time-to-first-token by ~35%.
    • Pricing model remains unchanged; costs are still based on standard token rates, optimizing network transfer rather than compute.
    • Threads expire after 5 minutes and do not support Zero Data Retention (ZDR), requiring local maintenance of full records for reconstruction.
