01What Codex Claude Free Means

Codex Claude free means using the AI coding tools Codex and Claude without paying for cloud model credits. You do this by adding free local models as an option inside your existing setup. That way, you still have access to powerful cloud models like Astra6 or Fable 5.1, but you can also switch to a local model when you want to save money or keep your data private.

The local model runs on your own computer, so you can even use it offline. In this episode, Julian Goldie shows four methods to make this work. The key idea is that the cloud model (Codex or Claude) can control the local model through prompts.

You never fully replace the cloud model – you just add a free option.

02Main Features You Get

With this setup, you get the best of both worlds. You can use premium cloud models for complex tasks and switch to free local models for simple or private work. Here are the key features:

  • Cost savings: Local models cost nothing to run after the initial setup. No API fees.
  • Privacy: Your data stays on your machine when you use a local model.
  • Offline capability: Local models work even without an internet connection.
  • Model switching: You can keep multiple models ready and choose which one to use for each task.
  • Flexibility: You are not tied to one provider. You can use any local model you install.

03How to Set Up a Local Model for Codex Claude Free

Follow these steps to use a free local model with Codex and Claude. This is method one from the episode:

  1. Install a local model on your computer. Julian uses LFM 2.5 2.6b as an example. You can choose any model you like.
  2. Tell your AI agent (Codex or Claude) to use that local model. You do this with a simple prompt. For example, ask it to control the local model.
  3. Command the cloud model to operate the local model. You say something like “Create a web page using LFM 2.5 2.6b.” The cloud model passes the work to the local model.

That is the basic method. The local model runs on your machine, and the cloud model acts as a controller. You can keep using cloud models for other tasks.

04How to Use Each Method for Codex Claude Free

Julian shows four different ways to use Codex and Claude for free. Here is how each one works:

  • Method 1 – Local model: Install a local model and let Codex or Claude operate it via prompts. You can ask for specific outputs like a webpage or a script.
  • Method 2 – Agent OS: Set up a local AI agent engine inside your agentic operating system. Then Codex or Claude can control that engine directly. This gives the cloud model control over your whole OS.
  • Method 3 – DeepSeek harness: Use the open-source DeepSeek agent harness. It has a model selector dropdown where you can add both local models and cloud models (like Astra6 or Fable 5.1). You switch models right inside the interface.
  • Method 4 – Free API: Instead of a local model, get a free API key. Julian mentions Token Harbor, which gives free access to DeepSeek v4.1 flash for two weeks. You plug that API into Codex or Claude, and they can delegate work to it.

Each method gives you a free option alongside your paid cloud models. Choose the one that fits your setup best.

05Four Methods Explained in Detail

Let’s break down each method a little more. Method 1 is the simplest – you just install a local model and command the cloud model to use it. No extra software needed. Method 2 requires you to have an agent OS, but then Codex or Claude can control that system directly. It gives you more power but also more complexity.

Method 3 uses DeepSeek harness, which is fully open-source and customizable. You can add any model to the dropdown. This is the only tool that lets you switch models inside the same interface. Method 4 is great if you do not want to run a local model.

You just use a free API key from a service like Token Harbor. The cloud model can call that API for free.

Julian says the method you choose depends on your needs. If you want offline use, go with a local model. If you want quick API access, use the free API.

DeepSeek harness is best for people who want full control.

06Tips, Limits and Mistakes to Avoid

Here are some things to keep in mind when setting up Codex Claude free:

  • Local models are slower than cloud models. They run on your computer’s hardware. Do not expect the same speed as GPT-4 or Claude.
  • You need enough RAM and GPU to run a local model like LFM 2.5 2.6b. Check your system before installing.
  • Method 3 (DeepSeek harness) is more complex because you have to customize everything. Only use it if you are comfortable with open-source tools.
  • Free API keys have limits. Token Harbor’s free key lasts two weeks. After that you may need to pay or find another free source.
  • Do not try to fully replace cloud models. Julian emphasizes that you should add local models as an option, not a complete replacement. Keep your main cloud model for heavy tasks.

Avoid the mistake of thinking you can run everything offline with a tiny model. Small local models are good for simple jobs, not complex coding or reasoning.

07Who Should Use Codex Claude Free Setup

This setup is for anyone who wants to use powerful AI tools without spending a lot of money. Developers, freelancers, and small business owners can all benefit. If you already use Codex or Claude but worry about API costs, adding a local model can save you hundreds of dollars per month.

Privacy-conscious users will like the option to keep sensitive data on their own computer. Offline use is also valuable if you travel or have unreliable internet. Julian created this episode because a community member named Chad asked how to keep using cloud models while also having a free local option.

This solution works for anyone in a similar situation.

Even if you only use AI occasionally, the setup is worth learning. It gives you more control over your tools and your budget.
