Claude Code and Codex are logging your token usage locally. Here is how to read it.

Developers using AI coding assistants like Claude Code and Codex can now see detailed logs of their token usage stored locally on their machines. These logs break down the tokens used in various ways, including input, cache operations, and output, without requiring any API calls or access to a provider dashboard. This newfound transparency means users can finally understand why they're quickly reaching their token limits and can take steps to optimize their usage. This level of insight into local activity is a significant step forward for better managing AI tool resources.
