1. Default (recommended) Opus 4.6 with 1M context · Most capable for complex work
2. Sonnet Sonnet 4.6 · Best for everyday tasks
3. Sonnet (1M context) Sonnet 4.6 with 1M context · Billed as extra usage · $3/$15 per Mtok
4. Haiku Haiku 4.5 · Fastest for quick answers
So there's an option to use non-1M Sonnet, but not non-1M Opus?Except wait, I guess that actually makes sense, because it says Sonnet 1M is billed as extra usage... but also WTF, why is Sonnet 1M billed as extra usage? So Opus 1M is included in Max, but if you want the worse model with that much context, you have to pay extra? Why the heck would anyone do that?
The screen does also say "For other/previous model names, specify with --model", so I assume you can use that to get 200K Opus, but I'm very confused why Anthropic wouldn't include that in the list of options.
What a strange UX decision. I'm not personally annoyed, I just think it's bizarre.
And as others have said it's very easy to burn token usage on the $100/month plan. It's getting to the point where it's going to very much make sense to do model routing when using coding tooling.
