I searched around hundreds of LLM Providers across the web and GitHub, To find LLM APIs that have a free tier and should automatically refill itself on a cycle, whether it could be daily, weekly or monthly.
This all started back where I wish to have a LLM API that is needed for my long-term projects. There are so many options I can choose from, but sometimes I just needed a lot of "fallbacks" to support my project.
But to prevent it from failing, the LLM APIs are needed to replenish itself, which considering I found a few of them and they are extremely common, It felt like it was not enough.
Having to add some providers which would have a one-time credit or a free trial would really not fit it, considering it would be drained in the long run, and never be able to use it again.
So, I've gone throughout the web, sailing across websites that promise Free LLM APIs to follow these two main goals:
- To be Free without billing info.
- To be Replenishable without one-time or trial credits.
I also have a third goal if second condition fails: If it's not Replenishable, it must have at least one free model available in their catalog that works without wasting a single credit dime (>=$0.0000001), and without asking to require credit top-ups.
I went through several popular AI agents with their provider documentation showing a list of providers, so that my goal is to sign myself up as a normal, unpaid user whose requirement is to know whether it refreshes its free quota or not. Not only that, I did explore a lot of GitHub Repositories finding providers that curators add onto their lists.
After I found many LLM providers that "promises" those two rules, it is not the end yet. So, I stress-tested their model endpoints from each provider according to their rate limits.
Surprisingly, the number of LLM Providers has dropped due to not having a single model found to be 200 OK but requiring payment. However, not all providers are dropped when some providers have one or more models recieving 200 OK from just a single prompt, without spending tokens.
To store it as helpful information, I made a repository that showcases all verified providers and its models under a single README. The number of providers that I found across the internet seemed to increase slow and steady overtime due to providers that are seen as obscure, but follows the main two golden rules that keeps the list on-topic as it was.
Hence, it is named "Free BYOK Models", where the theme suggests for "Free AI models from their BYOK-compatible LLM Providers that are free and replenishable."
This is solely for Text-generation endpoints, but it can support Vision-compatible models too. It is useful for trying to integrate API keys using these providers into their AI assistants, Coding agents, etc.
