The Ultimate Guide to Uncensored AI Models in 2025: Free and Open-Source AI

Updated: June 2025

Are you tired of AI that tiptoes around your questions? Frustrated when a promising creative idea gets shut down by a “safety” filter? I get it. As someone who lives and breathes local AI, nothing is more infuriating than having my tools decide what I’m “allowed” to think.

That’s why the world of uncensored AI models isn’t just a niche—it’s the future of creative and intellectual freedom. It’s about having an AI that works for you, without a corporate agenda.

After countless hours of testing, tweaking, and putting these models through their paces, I’ve created the definitive countdown for June 2025. We’re going to start at number 10 and work our way up to the undisputed champion. Let’s get started.

Why Use Uncensored AI Models?

Most commercial AI models, including GPT-4, Claude, and Gemini, have heavy restrictions in place. While these are designed for ethical AI use, they can hinder applications in:

• Independent AI research
• Creative writing & world-building
• Self-hosted AI assistants
• Automation & scripting
• Unfiltered data analysis

Now, let’s look at three AI models that offer maximum flexibility without external moderation. For a deeper dive into the ethical considerations of deploying agentic AI systems, check out this guide.
