This cost seems wild. For comparison GitHub Copilot Code Review is four cents per review once you're outside of the credits included with your subscription.
Not sure about that, I find it's generally pretty good at finding niche issues that aren't as easily caught by humans. Especially with newer LLMs it gets even better.
For comparison, Greptile charges $30 per month for 50 reviews, with $1 per additional review.
At average of $15~25 per review, this is way more expensive.
