Countless.dev makes it easy to explore, compare, and calculate costs for every AI model—LLMs, vision models, and more. Sort by price, token limits, or features, and find the perfect match for your use case in seconds.
Hey hunters 👋
I'm Ahmet, a 17-year-old high schooler from Turkey 🇹🇷
AI is evolving fast, and choosing the right model for your project shouldn't be complicated.
That's why I built Countless.dev—a platform where you can compare every AI model, calculate costs, and find the best one for your needs.
The process is simple:
Compare models by price, token limits, or special capabilities like vision.
Use the cost calculator to see exactly how much your use case will cost.
Try the side-by-side comparison to decide which model fits your needs perfectly.
The best part? It's 100% free and open-source. I built this because I know how overwhelming it can be to pick the right AI tool without spending hours digging through documentation.
Initially, I started this as an experiment, but after seeing the value it brings to developers and businesses, I decided to launch it for everyone. A sneak peek I shared on X/Twitter gained 45,000+ views, motivating me to bring it here.
Hope you find it helpful! I'd love to hear your feedback or ideas for improvement.
Happy hunting! 🚀
Ahmet
