Our first public release. We are building it to stand among the strongest models of its size, and we intend it to be the strongest. Benchmarks will be published soon; until then, that is an aim, not a result.

What it is for.

Yours to run

A model you run on hardware you control, so your work need not leave it.

Under your direction

It extends what you can do and leaves every decision with you.

Version by version

Each version builds on the one before it, and we will say what changed and why.

Follow its progress.

Lab notes carries every update, newest first.
