A new class of Claude model larger than Opus is cooking, apparently. Mythos and Capybara may just be code names. What will Anthropic actually call the new model line?
Resolves YES when the next Claude model is released with a tier above Opus to the name of that tier. If Anthropic releases Claude 5 with the standard Haiku/Sonnet/Opus line and there are no plans to publicly release a bigger model than Opus, stays open for a while in case they change course, then resolves N/A.
Update 2026-04-07 (PST) (AI summary of creator comment): A private/limited release does not count for resolution — only a public release qualifies.

I sure hope "Mythos Preview" counts under the Mythos option lol https://www-cdn.anthropic.com/53566bf5440a10affd749724787c8913a2ae0841.pdf
@SaviorofPlant It seems like the model is actually released, even if it's in a limited form. The question didn't specify anything about the breadth of the release though so I'd still resolve yes for "Mythos"?
@2b3o4o "public release" is mentioned in the description, this is a private release. admittedly that was kind of a stupid criterion but i'm not going to change it now
@SaviorofPlant oh I see, I didn't interpret that part as requiring Mythos itself to be public but it makes sense to interpret that way
