GPT Terra is 50% cheaper than 5.5 while being more performant. So it’s like a straight up 50% reduction in cost!
That leads me to a question. Why wouldn’t they just default to terra in ChatGPT in the last few months? If they didn’t then they burnt money for no reason by giving a shittier model at a higher price
Very interesting. My prediction is that Mythos would outperform Sol.
Also what does this tell about Yann LeCuns whole world model theory? Bro has been going on and on about it. He has made multiple wrong predictions on the trajectory of LLMs.
At some point his claim should be fully falsified no?
> On the Artificial Analysis Coding Agent Index, GPT‑5.6 Sol with max reasoning sets a new state of the art at 80, 2.8 points above Fable 5, while using less than half the output tokens, taking less than half the time, and costing about one-third less.
> That advantage extends across the family: Terra performs just above Fable 5, while Luna outperforms Opus 4.8; each does so in roughly one-third of the time, with about half as many output tokens, and at approximately one-quarter the estimated cost.
Wow. I don't believe it. Every indication and twitter post told me that Fable is much more intelligent than Sol and here we are told that even Terra outperforms Fable?
Not only that, Sol doesn't even come with run time classifiers. So it is even more suspicious.
What's even stranger is that OpenAI is directly referencing a competitor in this direct way.
- the tool calls and results are very legible, I can click them and see the progress
- no one talks about this but the tool call and response notification are handled much more elegantly in Codex. In Claude Code, it is handled in a clunky way using loops which always causes some delay
- you can steer the conversation midway in Codex
- /side is underrated (/btw is the equivalent and is much worse in Claude Code)
- I have to admit subagents are handled better in Claude Code
I notice something more interesting. This post shows Andrew to not only personally criticise Ben but also clearly shows an ideological stance against AI. I can see it from multiple angles - refusing AI PR's, refusing Anthropic's donation and multiple other things.
Either this ideology helps Zig position itself as a hand crafted language. Or this ideology is self defeating.
50 years ago we had religion for people to have something common to believe in. Now we have this. I think most people want a common enemy/scapegoat and an in-group presence. I doubt its about morals but more about self identity.
A poster who reactively posts "but Elon is a Nazi!!1!" does it not do out of care for Jews but more for establishing their own self identity. Within the mini-group, the poster aims to get the moral high-ground and status by speaking out against Nazi salute. It is absolutely not a moral thing because Natanyahu himself wrote a tweet vindicating Elon.
The same type of people show excessive concern towards AI's climate impact, "big tech bad" etc.
Ultimately its a new religion replacing the old one.
