## Summary

Anthropic has released message threads in public beta on the Claude Platform, letting agents send only new messages each turn instead of the full conversation history. For requests with 500k to 1M tokens, median time to first token dropped about 35% for most Claude Code users with the feature on by default. Threads are held in memory for 5 minutes after their last request, and token usage stays the same because Claude still reads the full conversation each turn.

## Why it matters

The post explains how message threads avoid resending full histories, which matters for teams running long agent sessions where latency grows with context.
