Anyone know if the model architecture overlaps with Jev, or is it just coincidence these are releasing at similar times?

As far as I know Jev's architecture isn't public (though I might be mistaken!), but it is a coincidence :)

Needle 3 has been in the making since Needle 2 launched early august, but we are very excited that Jev is bringing more attention to the problem we are trying to solve.
