Open the Web to AI: 17 Free Apps for Running LLMs Online

What are LLMs, and Why Do They Matter?

LLMs, or Large Language Models, are advanced artificial intelligence systems capable of processing and generating human-like text based on enormous datasets. They understand context, answer questions, summarize content, and even write code!

Think of them as an incredibly smart companion that knows a little bit (or a lot) about almost everything.

At Medevel.com, we’ve consistently highlighted open-source LLMs and RAG solutions.

Why? Because we believe in democratizing technology. Open-source projects not only reduce reliance on proprietary tools but also promote transparency and innovation.

From lightweight LLMs that can run on modest hardware to powerful alternatives for enterprise use, our platform showcases it all.

With this ethos, we encourage businesses, educators, and developers to explore open-source LLMs, integrate them into their workflows, and harness their potential to revolutionize industries.
