Claude Code Cuts Latency with Gzip, Prewarming

This is a high-leverage responsiveness fix: it removes dead time from the coding loop instead of chasing marginal gains in token generation.

• –Long sessions resend conversation history, files, and tool results; gzip can substantially reduce upload time, especially on slower connections.
• –Typing-triggered prewarming overlaps cloud container startup and connection setup with prompt composition.
• –Local sessions mainly benefit from smaller network payloads, while cloud users should see the largest first-response improvement.
• –Compression reduces transport overhead but does not reduce token usage, context growth, or prompt-cache costs.
• –Prewarming may consume resources for abandoned drafts, so Anthropic should clarify cancellation behavior and operational overhead.
