It IS confusing. I'm not even using Air.

Junie is their agent(?) that can connect to multiple providers. AFAIK you can bring-your-own-key or buy a subscription from them that lets you use your credits across multiple vendors (openai, anthropic, google) across a handful of models from each vendor. So yeah, you can use your openai credentials in junie vs paying for jetbrains junie credits.

Is it 'worth it'? I dunno. I've not used dedicated subscriptions. I adopted Junie when it first came out, and it's been 'good enough'. As I say, I've never hit the 'oh, i have to stop for several hours until they let me in again' wall because of just using the API approach.

As my monthly spend goes up, I might try something else out, but... gpt6-luna just came out. That is likely going to cut my spend already.
