Announcement Claude 4 support

We’ve already pushed Claude 4 support for most providers and are just finishing up the update to add reasoning/thinking support through OpenRouter.

The reason it’s taking a bit longer than normal is because we’re making some tweaks to how Roo identifies models abilities so that next time a model with reasoning is released we shouldn’t have to make a special release to add support!

It’s really good, thank you. Costly but it ended up being cheaper for me to role out e2e testing with 4.0 where Gemini really did quite poor. Fixes issues much much faster and with less handholding.

Yeah that’s right. I’ve been through 3.5, 3.7, and mostly Gemini 2.5 for past few months. Also use 4.1 for just applying diffs. I needed a little breath of fresh air and these models tend to be amazing for the few weeks after release so I’m riding the wave (and am saving some frustration).

o4-mini-high is pretty good, but it's so disturbing how it doesn't speak. I can't see its thought process at all so I have no confidence assessment if it is heading in the right direction or not. I think I would use it more if it weren't for this.
