**Release:** [llm 0.34](https://github.com/simonw/llm/releases/tag/0.34)

One new feature:

`llm logs --usage` Markdown output now includes the response duration in milliseconds and as a human-readable duration. `llm logs --short` includes a new `duration_ms` field. [#1653](https://github.com/simonw/llm/issues/1653)

Plus several contributed bug fixes, and a significant performance improvement to `llm logs` thanks to [waveplate](https://github.com/waveplate) on GitHub, see also [llm-openrouter 0.7.1](https://simonwillison.net/2026/Sep/2/llm-openrouter/).
