Go get them. If you look heard enough you may find stock piles of these chips in warehouse somewhere that someone bought off an auction. maybe not on ebay:) but these days you never know.
Well, they just pulled one of the strongest models I've ever used. My concern isn't that I'll have to go back to 4.8 or GPT-5.5, it's where do they stop? What if they decide 5.5 or 4.8 are too powerful too? Do those get removed next?
Is open source next on the list?
Better grab the latest open source models now and get your Blackwell 6000, Spark, or Mac mini fired up and ready to go. I think you're going to need it.
