Claude Code hasn't updated yet it seems, but I was able to test it using `claude --model claude-opus-4-7` Or `/model claude-opus-4-7` from an existing session edit: `/model claude-opus-4-7[1m]` to select the 1m context window version

~~That just changes it to Opus 4, not Opus 4.7~~

My statusline showed _Opus 4_, but it did indeed accept this line.

I did change it to `/model claude-opus-4-7[1m]`, because it would pick the non-1M context model instead.

For anyone who was wondering about Mythos release plans: > What we learn from the real-world deployment of these safeguards will help us work towards our eventual goal of a broad release of Mythos-class models.

Oh look it was too powerful to release, now it’s just a matter of safeguards. This story sounds a lot like GPT2.

The original blog post for Mythos did lay out this safeguard testing strategy as part of their plan.

Too late, personally after how bad 4.6 was the past week I was pushed to codex, which seems to mostly work at the same level from day to day. Just last night I was trying to get 4.6 to lookup how to do some simple tensor parallel work, and the agent used 0 web fetches and just hallucinated 17K very wrong tokens. Then the main agent decided to pretend to implement tp, and just copied the entire model to each node...

Before opus released we also saw huge backlash with it being dumber.

Perhaps they need the compute for the training

Have they effectively communicated what a 20x or 10x Claude subscription actually means? And with Claude 4.7 increasing usage by 1.35x does that mean a 20x plan is now really a 13x plan (no token increase on the subscription) or a 27x plan (more tokens given to compensate for more computer cost) relative to Claude Opus 4.6?

Does it run for you? I can select it this way but it says 'There's an issue with the selected model (claude-opus-4-7). It may not exist or you may not have access to it. Run /model to pick a different model.'

Weird, yeah it works for me

Mythos release feels like Silicon Valley "don't take revenue" advice:

https://www.youtube.com/watch?v=BzAdXyPYKQo

""If you show the model, people will ask 'HOW BETTER?' and it will never be enough. The model that was the AGI is suddenly the +5% bench dog. But if you have NO model, you can say you're worried about safety! You're a potential pure play... It's not about how much you research, it's about how much you're WORTH. And who is worth the most? Companies that don't release their models!"

Not showing up in claude code by default on the latest version. Apparently this is how to set it: /model claude-opus-4-7 Coming from anthropic's support page, so hopefully they did't hallucinate the docs, cause the model name on claude code says: /model claude-opus-4-7 ⎿ Set model to Opus 4 what model are you? I'm Claude Opus 4 (model ID: claude-opus-4-7).

It does not work, it says Claude Opus 4 not 4.7

> Opus 4.7 uses an updated tokenizer that improves how the model processes text. The tradeoff is that the same input can map to more tokens—roughly 1.0–1.35× depending on the content type. caveman[0] is becoming more relevant by the day. I already enjoy reading its output more than vanilla so suits me well. [0] https://github.com/JuliusBrussee/caveman/tree/main

Another supply chain attack waiting?

Have you tried just adding an instruction to be terse?

Don't get me wrong, I've tried out caveman as well, but these days I am wondering whether something as popular will be hijacked.
