01What Are Free AI Models and How Do They Work?

Free AI models are AI systems you can use without paying for a subscription. In this episode, Julian Goldie shows you how to access over 90 of them through open-source projects called OmniRoot and NineRoot. These projects give you free APIs that you can plug into any AI coder of your choice.

The key idea is that you don't need to pay for expensive AI tools. You can use free models as the brain behind your coding projects. This opens up AI development to anyone, even if you're on a tight budget or just starting out.

02Main Features of OmniRoot and NineRoot

OmniRoot and NineRoot are free AI routers. They give you access to many free APIs in one place. The main features are:

  • Auto-fallback: If a free API gets rate-limited, the router switches to another free API automatically. You won't even notice.
  • Universal compatibility: Works with Cloud Code, Cursor, Client, and any CLI tool.
  • Customizable: As open-source projects, you can modify them to fit your needs.
  • Token compression: A built-in system called RTK reduces the tokens you use, helping you avoid rate limits.

Julian also mentions that OmniRoot has 37,000 GitHub stars, and NineRoot has 24,000. This shows they are popular and trusted in the community.

03How to Set Up Free AI Models with OmniRoot

Setting up free AI models with OmniRoot is straightforward. Julian shows how to plug it into your AI coding tools. Here are the basic steps from the episode:

  1. Get the OmniRoot project from its official source.
  2. Choose your AI coder (like Free Cloud Code or a CLI tool).
  3. Connect OmniRoot as the brain for that coder.
  4. Start using free APIs for your coding tasks.
  5. If you want, install NineRoot as an alternative router.

Julian also mentions that you can use these routers inside the agent operating system, which he demonstrates in the episode. You don't need to be technical – many members of his community are non-technical.

04Using Free AI Models to Build Apps and Automations

Julian shows a practical example: building a fun keyboard app using BigPickle, a free API plugged into the system. He uses a custom AI coder he built himself, which allows switching between OmniRoot and NineRoot.

The process is simple: you type what you want, get the code, and see a preview. You can save your builds for later. There's a conversation history and a prompter to guide the AI.

He also explains how to use free AI models for SEO content pipelines. You type a keyword, plug in a case study, and OmniRoot generates content.

  • Build custom workflows that operate with OmniRoot.
  • Link to your local memory system (like Obsidian) for personalized output.
  • Use free AI models to delegate tasks to subagents.

05Results and Performance of Free AI Models

Julian tests the free AI models and shows the output. He says it creates 'nice stuff' and 'amazing stuff.' It's not Fable 5 level, but for free, it's pretty good.

He notes that the apps actually work and build nicely. The free AI coder he used produced a mini app that worked perfectly. He also mentions that these free models can have better outputs when used with a good harness like OpenCode.

Julian says the system 'has never really failed on me.' This suggests reliability even with free APIs.

06Tips, Limits, and Mistakes to Avoid with Free AI Models

Free AI models have limits, like rate limiting and token exhaustion. To avoid these, use the RTK system that compresses token usage. Julian also recommends using auto-fallback to switch APIs when you get rate-limited.

One mistake is thinking you need to be technical. Julian says you don't – he himself is not technical and doesn't use HTML.

  • Don't assume free models are low quality – they can produce great results.
  • Use free APIs even if you have paid subscriptions – they're good for delegating to subagents.
  • If you use a paid model like Claude, you can free up tokens by using free APIs for coding tasks.
  • OpenCode is another tool you can use for free coding with models like DeepSeek V4 Flash.

07Who Should Use Free AI Models and Why It Matters

Free AI models are for anyone who wants to build with AI without paying for subscriptions. Julian emphasizes that the barrier is no longer the API cost – it's just starting to automate and take action.

He shares that even though he has paid subscriptions like Claude, Grok, and ChatGPT, he still uses free APIs. They are great for delegating tasks and saving tokens.

This is especially useful for non-technical users who want to create apps or automations. Julian's community has 207 pages of testimonials, and most members are non-technical. So if they can do it, you can too.
