A comment on Claude Fable 5.2 and Mythos 5.2.

“Testers have found that Fable 5.2 and Mythos 5.2 communicate more clearly than past Fable and Mythos models. They generate outputs up to 30% faster than Claude Fable 5.1 and Claude Mythos 5.1, and they’re available at a lower price: $8 per million input tokens and $40 per million output tokens.”

Honestly incredible that they’ve managed to beat all benchmarks, while making it cheaper. Always happy to see improvements offered at lower costs.

Will be interesting to see what OpenAI does in response

They still need a response to Opus 5.5

It's really true.

I think frontier models feel terrible after a new model requires you to do less babysitting, it's just really hard to go back once you've had to handhold less.

The only way I use Astra and 6.1 Sol now is if they're being orchestrated by Opus 5.5 so I don't have to talk to them directly.

GPT-6.1-Sol is so incredibly sloppy and dumb, it's embarassing.

Maybe because it is so cheap.

They want to condition you to equal cheap with bad

It seems like OAI, with the GPT-6 models, focused a lot more on computer use, math, and maybe spatial/visual intelligence, more so that code. Compared to Ant. that seem to focus on code much more.

Reminds me of GPT-5, smart but wrote crap code, until they improved the code training with 5.3 and 5.4.

the winning benchmark is much more expensive than what it cost for the same on 5.1

i'm begging people to stop looking at token prices
