Are we to understand "model released" as the current situation with Project Glasswing, or must it be released to the public as well?

@DylanRichardson must be released to the public

Does anybody know why it won't let me add more questions to this market?

So this would just be agi?

@JoeandSeth no

@Bayesian yay

bought Ṁ10 YES

@JaundicedBaboon On release or by market close?

bought Ṁ10 NO

I was wondering this also

@2b3o4o for the API/max plan I’ll say it’ll resolve 30 days after release, for everything else it’ll resolve after the model comes out and relevant information is revealed
