Misremembered, the main thrust of the comment still stands, the 100K context window isn't "real", it would be absurdly expensive to do it for real. They are using a lot of approximation tricks to get there.
Yep, mistype on my end as well. Claude just fails to process the request if you get above 100k tokens (I've done that, heh).
Yes, that's the point now for competing AI research-for-profit companies, whatever metric is technical and sounds important, is going to be used in marketing and valuation determinations. It will be explored for research I'm sure, and then determine its product viability. It's nice competition, but agree, that it can be deceptive.
