Welcome to Hollowatt Notebooks!

This notebook wires up Larkline, an open transcription model, then charts how its attention drifts across a field recording with sparkgrad, adapted from a shared example.

We started you on a single HX2 accelerator, which you can see in the Runtime panel on the left. No need to babysit it — you only pay while the notebook is awake, and it powers itself down once you stop working. Check your usage any time.

Hollowatt accounts include $24 of compute credit every month. Let’s get going.
