So where can I try out Genie 3? Did the author try it out?

If not it's just vibe^2 blogging.

Genie 3 just had the Sora treatment.

Lots of press for something by invitation only.

This probably means it takes an incredible amount of resources to power in its current form. Possibly tens of H100s (or TPUs) simultaneously. It'll take time to turn that from a wasteful tech preview into a scaleable product.

But it's clearly impressive, and it did the job of making what OpenAI did look insignificant.

Basically free advertising for something not released.
