Microsoft said it had finished pre-training MAI-Base-2, a 2.8-trillion-parameter mixture-of-experts model, and that it would license the weights to partners rather than post them for everyone.
I am reading Microsoft MAI-Base-2 as a report about Microsoft. If you are not a company that has treated OpenAI as its only frontier source, you can leave it. Not every true item is your item.
The gap stays a gap. Microsoft MAI-Base-2 does not get a borrowed number, a motive, or a winner from a looser retelling.
Treat it like a desk note: useful if it changes a setting or a claim you were about to repeat, disposable if it does not. Come back only when Microsoft puts the same claim in its own words.
