uzu 0.6.8 installs as a local model provider for the Pi coding agent

On 15 October 2026 the npm registry published @trymirai/uzu-pi-extension version 0.6.8 at 16:20:33 UTC and pointed the latest tag at it. The description is “On-device Uzu models for the Pi coding agent.” The registry document and the 0.6.8 tarball carry the same constraints. The package is a local provider for uzu, Mirai’s Rust engine, inside the Pi coding agent.

What the package allows

os is only darwin. cpu is only arm64. The license is MIT. Node must be >=22.19.0. The sole dependency is @trymirai/uzu at exactly 0.6.8. Peers are @earendil-works/pi-ai and @earendil-works/pi-coding-agent, both ^1.1.0. The tarball sets the Pi extension entry to ./index.js.

That tarball’s README matches the file at tag 0.6.8: Apple Silicon macOS, Pi 1.1 or later, Node.js 22.19.0 or newer. The install line is:

pi install npm:@trymirai/uzu-pi-extension

The command is the one printed in the README. It was not executed here.

@earendil-works/pi-coding-agent has latest at 1.3.0, published 15 October 2026 at 19:13:30 UTC, MIT, with the same Node floor. Version 1.3.0 satisfies the ^1.1.0 peer. Nothing in the extension metadata names Windows, Linux, or an Intel Mac. Apple Silicon macOS is the supported platform.

Models, and the same-day workflow fix

Open /model in Pi and pick a model under the uzu provider. The picker shows whether the weights are downloaded. Mirai’s recommendation in the README is “Qwen3.8 27B Mirai Medium Quantization.” Downloaded models stay in uzu’s cache. For a checkpoint converted separately, set LOCAL_PATH to a model directory, or to a directory of models, before starting Pi. The tarball has no speed table, so this note has no tokens-per-second claim. Figures from the earlier uzu piece stay on that page.

Commit 698d612, “Fix pi release workflow (#968),” is dated 15 October 2026 at 15:57 UTC, before the 16:20 publish. The patch changes the release workflow from a single npm view check to a wait of up to 30 minutes for @trymirai/uzu at the same version. No Actions log was opened. The patch and the registry timestamp are the record, in that order. The package created time is 16:19:16 UTC, and the version list also contains 0.0.0-stage. latest is 0.6.8.

The GitHub API at 05:36 UTC on 16 October listed 2,352 stars. The repo license is MIT and the language field is Rust.

On an Apple Silicon Mac, with Pi 1.1 or newer and Node 22.19.0 or newer, the documented step is the install above, pinned to uzu 0.6.8. The Pi 1.0 write-up covers the host. This package is the new local provider, limited to darwin and arm64.
