not sure wym, it's in the headline of the article that Opus 4 has 200k context

(same as sonnet 3.7 with the beta header)

There's the nominal context length, and the effective one. You need a benchmark like the needle-in-a-haystack or RULER to determine the latter.

We might be looking at different articles? The string "200" appears nowhere in this one --- or I'm just wrong! But thanks!
