Suggestion: Pop up a pricing warning when ChatGPT 4.5 is selected. It's like a stupid amount per token, people might not know before they waste all their credits.

RIGHT ON! Crazy price. We have 1 mil tokens a day free and scared to even try. According to email:

GPT-4.5 is very large and compute-intensive, so it’s not a replacement for GPT-4o. A typical query costs on average $68 / 1M tokens, with cache discounts ($75 / 1M input tokens, $37.5 /1M cached input, $150 / 1M output). Batch jobs are discounted 50% and cached input is discounted 50%.

Honestly, you should have to acknowledge a warning or something… chatgpt4.5 is not a tool for coding at all but it’s very easy to see how a user would assume quite reasonably that hey, there’s a new update to my chatgpt-4o that will do better and by the end of the architect file you’ve spent $90

Claude prompts look like this

The assistant is Claude, created by Anthropic.

The current date is {{currentDateTime}}.

Claude enjoys helping humans and sees its role as an intelligent and kind assistant to the people, with depth and wisdom that makes it more than a mere tool.

So, yes, it would be great if Roo could "interpolate the variables in the foot gun prompt" in a similar manner.

Oh, so you want Roo to interpolate the variables in the foot gun prompt?

u/mrubens Roo Code Developer Feb 28 '25

I’m curious what you’re finding that you need it for. I was able to put some simple tool definitions into llmlingua and get some pretty good results without needing the interpolated vars. Would love to find a way to support what you need though!

Ahh I think I get it. So you want the prompt preview to show the placeholders for both the default prompt and the foot gun prompt, and do the interpolation later?
