I'm confused. I thought Mythos 5 and Fable 5 were exactly the same model just with a different security layer in front of it.
Could they mean the Mythos 5 Preview?
replyYes. One reason why I think that report has confused Fable and Opus.
reply> I believe this report has confused Opus (which is known to be around 5T) and Fable.
reply5T for Opus feels quite high though. DeepSeek V4 Pro is a mere 1.6T and often described as a match with Opus in overall quality. Even the largest open models in common use are around 2.8T.

replyIt's not. Idk about who has more T's but, unfortunately, DS4 pro is not a match to Opus, at least not Opus 4.8.
It's not an Opus match.
replyThe difference is very visible in long tail applications. Exactly where you'd expect parameter count to matter.
