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

@ahmet_dedeler this is awesome Ahmet, love seeing young devs solving real problems with open source!!! 🙌 curious how do you keep the model data updated as new ones drop or prices change? super useful tool btw

@tonyabracadabra thanks! the data is fetched from LiteLLM open-source repo :) gets fetched everyday, so constantly updated!

@ahmet_dedeler great! hope you reach a bigger milestone soon!

@tonyabracadabra @ahmet_dedeler I love this, great work. Please make the website faster though, it is sometimes slow :D

great tool if you're building an ai app - need to check it out

@rexanwong thanks! let me know what you think :)

what do y'all think of the product? any thoughts/suggestions welcome!

@ahmet_dedeler Fantastic work mate! Really simple and elegant way to compare and search models. One suggestion I have is to add a filter to limit model search results to those recently released and also by provider. This would help limit the amount of models being displayed all at once on certain categories.

@mkairys Thank you for the suggestion! You can actually sort by provider, if you click on the "Provider" you'll see a list of the providers. Good idea, I'll look into adding sorting by recently released models!

An excellent product—extremely helpful and practical!

awesome app I really liked its open source
