I’d only heard of OpenRouter by name, but I didn’t realize it could be this useful, from switching models to saving on token costs, haha. Now I want to try using it for my personal projects right away. I’ll make sure to complete the entire course.

I was surprised that applying what I learned to my project significantly reduced the API costs, haha. I thought all I had to do was switch models, but there were other ways to use them efficiently. The explanation was easy to understand and immediately practical, so it was really useful!

I’m already using Claude Code quite effectively, but this is even better organized. Thank you.

I listened to the lecture and applied what I learned to a personal project, and I was surprised by how much it reduced token usageㅋㅋ It made me realize I’d been wasting quite a lot of tokens all this time~ I’d always felt lost about how to design an efficient architecture, but now I have a clearer direction. I’m very satisfied that I was able to put what I learned to use right away!
