## Post

Our v2 small model is here.
I've been using it daily for a variety of things.

The pre-training ran for 68 hours on GB300s. Post-training was 17 million rollouts over 9 days.
Entirely pre-mid-post trained in NVFP4.

Available to train and fine-tune on Tinker right now.
Open weights next week after external safety testing is fully complete (cant skimp on that).

Continuing to decentralize and democratize intelligence...
