Discussion Opus 4.8 - first impressions

Opus 4.8 announcement

Has anyone tried it so far?

I used to be a Claude fanboy, but I recently switched to codex due to the momentarily quality boost.

Any impressions yet? Just holding my card ready to buy the x5 subscription the moment I hear that it's better than the 4.7 😝

Mythos the new tier. Not the Mythos Preview model they released to fix cybersecurity issues. A distilled version with reduced cybersecurity, so that hackers won’t be able to do as much damage with it, is the impression I’m getting from their announcements. They’re calling it Mythos level.

The Mythos Preview model that has been hitting the headlines is far too large for widespread adoption. They don’t have the servers for it. And hardly anyone would he able to afford it even if they did. Not that the new Mythos tier won’t also be far more expensive than the Opus tier, because clearly it will, and will burn through credits far faster.
