They have the 32B listed as "stage 1" with the note "final checkpoint to be released." So, not finished yet. Not sure why you'd release it if it's not finished, but that's the explanation.
The 7B does look very, very good however.
32B performs worse than the 7B model so I'm sure they will improve it
In this case, the fully open source pipeline is probably as valuable or more so than the weights, so releasing early has some justification.
