The Best Free AI API Key Providers

Most people are used to using AI in chatbot interfaces, such as Gemini or ChatGPT, but they have a problem: you are limited to using them in whichever ways the companies allow for. This is really annoying when you want to code or make custom tools that are powered by these models. There’s also the problem of apps limiting how much you can use AIs, or dynamically lowering how much you can use them in peak hours.

The easiest solution to this problem is using free API keys, or basically passwords to connect to servers hosting AIs. Right here, in Accelerated Logic, you can put these in, along with the model ID, and you can talk with AI models.

Google AI Studio is one of the best API key providers, especially if you want to use the absolute best AI models made by Google. You get access to proprietary models such as Gemini 3.5 Flash, 3.1 Pro, and 3.1 Flash-lite, as well as open-source models like Gemma 4 26b and Gemma 4 31b. Flash and Pro level models are capped at only a few requests per day, while access to Flash-Lite models and open-source ones are pretty much unlimited, however the biggest problem is that at peak times, you might find that it won’t work, so it’s not the most reliable thing on earth. But, if you just need a quick response, then it’s fine.

OpenRouter is the most popular place to get access to frontier models from pretty much every AI lab. It also has a rotating cast of free models like Nemotron 550b and the aforementioned Gemma 4 models. It has pretty high limits, so I would definitely recommend it. The only thing I would say, is that s

Nvidia NIM has every AI model from Nvidia, and also powerful open-source AI models like GLM 5.2 and DeepSeek V4 Pro. It doesn’t really have limits, but sometimes it is a little slow.

Ollama is not only an app that you can download and run AI models on, but also is a provider of cloud models. You can get an API key by signing up. You can get access to models like Nemotron 550b and DeepSeek V4 Flash, and there is a pretty generous weekly usage limit.

Mistral, once one of the dominant forces of open-source AI, has now shifted towards serving their massive models as a service. The great thing about this is that you get pretty much unlimited access to their latest models. However, the only caveat is that there are tight limits on how many tokens you can enter per minute, especially for Mistral Medium and Large, so just keep that in mind if you need to enter in large prompts or files.

Groq is a provider of incredibly fast inference. Its free tier is pretty generous, and allows you to use models like Qwen 3.6 27b and GPT-OSS 120b. However, it also has strict token per minute quotas, and because it is so fast, you can burn through them really fast.

Cerebras is quite similar to Groq, but its free tier only has 3 models: GLM 4.7, GPT-OSS 120b, and Gemma 4 31b. But, these models are even faster than Groq’s in terms of tokens per second, so that could be for some people a worthy tradeoff.

Hugging Face is a platform where you can download open-source AI models, but it also provides a small monthly quota of AI inference, which you can use on smaller AI models.

Cohere makes the North family of models, which aren’t the most powerful, but Cohere gives you a really high quota for them, so using AcceleratedLogic’s multi-agent systems, you can actually make them a lot better at coding.

Poolside makes the Laguna M and XS family of models, which are very good at programming. While you can access them for free on openrouter, you can also get a direct API key from poolside itself.

Overall, there are many ways to get free access to AI api keys, and you can use them all for anything, ranging from refactoring entire codebases to writing emails. Also, in AcceleratedLogic, you can create fallback chains using multiple models, so if you get to the limit of one model, it will use a backup one.
