Yes that the same, in the "Your Account" section of the service you have "Chat Credits" field, it was seeded with $10 initially and I got it down to $0.11 in one evening. You are right about the pricing page, it does say it's $10/month, but I believe it's $10/month up to some amount of queries in actuality, because they obviously can't offer infinite inference for $10. Maybe I was "holding it wrong", sending too much complete files as part of prompt and the token use and context window skyrocketed, but I absolutely used my initial $10 in one evening, unlike with Claude...
From what I can tell inside the product, the public pricing seems deceptive.
It appears that for the $10/month you just get access to additional features (e.g. bigger context) + a budget of $5/month of credits. The credits possibly translate 1:1 to the usage costs of the underlying models you chose.
I asked it to add some missing documentation with the Claude 3.5 Sonnet model to a medium-sized Python file (2k lines) as a first test and that used up 13 cents of the credits. If it were working in a really productive way (where I'd also include more files as context), I'd probably burn through $20-50/day.
I'm wondering why they are not publicly showing some more transparent pricing. Yeah, this method will bump their signup numbers for investors, but it also absolutely wrecks their churn numbers, when people immediately cancel in the first hour.
Supermaven has a $10/month subscription which covers unlimited use of the in editor code autocomplete stuff.
It also has a pay as you go chat which is integrated into the IDE w/ hotkeys, however the above subscription gives you $5 free credits for it a month. This doesn't call their own model but stuff like gpt-4o which is presumably why they don't offer unlimited free usage.
