The mode claude-sonnet-4 does not work with your current plan

It seems like the naming might be wrong?
they updated the naming from claude-3.5-sonnet to claude-sonnet-4 ? i think thats what it seems.

I am also facing issues with the pro plan and access to sonnet 4. Opus is labeled MAX only.
I have to enable priced-useage to be able to use sonnet 4? thats the only way i got it to work.

This what my useage logs are saying.
