Damnit lol. Does sonnet 4.5 still work? And if so how would I go about changing the model? :o thanks man

OMG, this is very sad news and a very sad day for humanity.
I haven't had time to do much with this model due to being busy. We only realize its value when we lose it.

Do any of the other ones work?

You just need to restart Kiro Gateway for the models to update.
Yes, Sonnet should work. I see the log 2026-01-17 06:19:29 | DEBUG | main:lifespan:350 - Loaded 4 models from Kiro API: ['auto', 'claude-sonnet-4.5', 'claude-sonnet-4', 'claude-haiku-4.5'], but I'm not sure about its coding abilities compared to Opus.

I was excited to create this project because Opus was on the list of models.

Ahh ok got yeh, cool. Yeh it's kind of shitty that they removed it but it's probably cause everyone was abusing it haha

I was willing to put up with 200k context just because of the power of Opus, and now it's like I've lost a finger.

Because Sonnet, which I used on my private gateway for Antigravity a few months ago, was used as a simple model for editing with an already-formed context by Gemini 3 Pro (High). I didn't trust Sonnet with complex code.

Anyway, I'll update the project's readme now.
