Mythos/Fable was the state of the art back in March, if not earlier.

So China is now only 4 months behind US frontier models now when the rule of thumb was 6 months just a little while ago.

To be fair the lag varies tremendously. When Deepseek first came out it was competitive with frontier lab models at the time.

Well the same is true for Kimi. Before it, Fable was at the lead. Kimi is at the same level as Fable generally. Sometimes better, sometimes worse.

It released in June..

To the public. Mythos has been in active use for quite a while.

It makes no good sense to evaluate models we don't have access to. For all we know K3 was competitive back then too. Or maybe there's a K4 in the works that blows everything out of the water. Who knows and who cares. There's no way for us to compare

[broodbucket]

There isn't, I think the point is in terms of how "far ahead" models are, K3 was likely trained much more recently than Mythos was. It's just something to note, it's not especially prescriptive.

Mythos was withheld because of the threat to security and/or marketing stunt (depending on your leaning), I don't see what benefit there could be for not releasing K3 immediately.

Mythos Preview was also priced at $125/million token output. Completely different pricing class.

I wonder if Fable now is actually better than the Mythos in March and if it's actually the same model. Could just be more Anthropic shenanigans.

Isn’t Fable just a restricted version of Mythos?
