Finally, OpenAI has a Fable/Mythos class model. 5.6 Sol felt like 5.5 on steroids, probably just a different checkpoint with a lot more RL post training. I wouldn't be surprised if there are some conceptual similarities to the kind of latent reasoning Anthropic sees in claude's J-space, although those aren't the same thing. Recurrent/looped transformers themselves aren't a new concept, but it's interesting to finally…

yeah i'm wondering the same way... especially in light of the 20x debacle (where we found that 20x of Max vs 5x only applies to the 5hr limit, not the weekly limit, whereas OpenAI's 20x actually is 20x overall).

Also Opus 5 has been really tough to work with. I can't understand half of what it says, it's just so damn obscure.

GPT 6 Astra benchmarks https://cdn.thenewstack.io/media/2026/09/358eb84a-screenshot... Performance is significantly higher than Fable 5.1 Source: https://thenewstack.io/openai-gpt6-astra-benchmarks/

any benchmark where opus 5 achieves higher scores than fable 5 in any way is not a benchmark worth trusting.

Why would Anthropic trust and use these tests in their official comparisons?

They broke up a while ago, why is this surprising?

Would be surprising if it's not on all 3 major clouds soon enough because that's been their general strategy since said break up

You should know: AA index is only 61. Pretty surprised it’s that low.

This is actually a really good thing imo. If they didn't care about benchmaxxing it means that they really know that what they have in hand is good.

The latest OpenAI models have still been available via Azure foundry. Exclusivity to AWS would be a marked shift.

> Performance is significantly higher than Fable 5.1 That's not clear. Need to see independent benchmarks first.

Artificial Analysis just published their aggregate score (61).

Still below Fable 5, let alone Fable 5.1.

EDIT: This is suspiciously low. Calls the relevance of existing benchmarks into question.
