01What Does It Mean to Run Agent OS for Free?
Running an agent OS for free means using an AI-powered operating system that coordinates multiple AI agents without paying for expensive API usage. In this episode, Julian Goldie answers a viewer question about the cost of agent operating systems and shows several strategies to bring the cost down to zero.
You can run agent OS for free by using free models like Omni and Hy3, or by using local models on your own computer. Even the harnesses—the software that connects the models—can be open source, like Hermes or free Codex. This way, you avoid paying for both the models and the orchestration layer.
02Key Features of Agent OS for Free
The agent OS is a customizable environment where you can run multiple AI agents working together. Unlike a basic agent like Hermes Agent, the agent OS lets you combine different models—Claude, Hermes, Antigravity—in one system. You can build custom workflows, such as having Hermes Oracle and Hermes Astros work together to research competitors and trending topics in your niche.
The user interface is also different, offering more control and visual feedback. You can even control the agent OS through Buzz, a free open-source tool often described as 'Slack for AI agents,' because it links to Claude and Codex, which can orchestrate the agent OS. This gives you the flexibility to choose your preferred interface.
03Step-by-Step Setup for Running Agent OS for Free
- Choose a free or local model. Options include Omni, Hy3, or a local model on your computer.
- Select an open-source harness. Hermes or free Codex are good choices to keep costs at zero.
- If you want free APIs, go to OpenRouter, log in, subscribe to the free tier, and connect your account.
- In your terminal, type hermes model to switch between the free APIs you want to use.
- Pick free models from the list, like Ling 3.0 Flash, which is free with Hermes Agent.
- Once set up, you can use Hermes Agent or the full agent OS with multiple agents and custom workflows.
04Examples of Using Free Agent OS in Practice
Julian shows how to use the free setup by connecting OpenRouter free APIs to Hermes Agent. He switches between free models using the command hermes model in the terminal. This allows you to use free models for research and coding tasks without paying.
He also mentions using the agent OS for practical projects, like creating a Minecraft game test or generating slide decks. The agent OS can handle multiple agents working together, and you can even create 3D mockups using Hermes Agent with Blender MCP—a feature that is usually too technical for most people but becomes accessible with this setup.
05Results and Comparisons from the Episode
Julian tested several tools and shared his findings. He found that the agent OS works well even with free models, but some tools have limitations. For example, Chat Chippity Voice (a voice AI tool) is fun but 'brutal' and 'unusable' for computer use—it struggles with basic tasks and responds slowly.
Julian says it's a very beta version, but the future potential is scary.
He also compared Hermes Agent to the full agent OS, noting that Hermes Agent is basic and limited, while the agent OS offers much more customization and multi-agent coordination. In terms of model performance, he mentions that Opus 5 has slowed down and gets distracted easily, circling around problems instead of being direct. He also notes that Gemini 3.6 Flash is better than the old Flash, but everyone is waiting for Gemini 3.5 Pro.
06Tips, Limits, and Mistakes to Avoid
When running agent OS for free, you can avoid common pitfalls. First, if you struggle with a specific tool like OmniRoot, don't get stuck—use alternatives like OpenRouter's free APIs instead. Julian also warns that free models may not be production-ready for all tasks, like the Minecraft game test, but they are great for experimentation.
Be careful with voice AI tools like Chat Chippity Voice—they can consume credits quickly, so monitor your usage. Also, avoid relying on them for computer use as they are currently unreliable. When using AI voices, remember that your brain may confuse the AI with a human, so be mindful of what you share.
Finally, if a feature like extra high reasoning isn't available, contact support or try different browsers or devices.
07Who Should Run Agent OS for Free?
Running agent OS for free is ideal for anyone who wants to experiment with AI agents without a budget. It's perfect for hobbyists, students, and professionals who want to learn or prototype. Julian, for example, uses it to create content and test AI creations on his Goldie Bench.
It matters because it democratizes access to advanced AI tools. You can run a fully functional agent OS without spending a dime, and with free Chinese models like Ling 3.0 Flash available, the competition keeps driving quality up. Whether you're a developer or a content creator, this setup lets you explore AI's potential without financial risk.
08Additional Tips from the Daily Update
Beyond the agent OS, Julian shares other tips. For Google Gemini users, if you don't see the latest models, try the Antigravity app instead. For Notebook Gemini (formerly Notebook LM), if slide generation fails, try a different account, phone app, browser, or clear the cache.
These small tweaks often solve common issues.
He also talks about content creation: creating more content works if you quality control it. He has a team that produces videos, and he reviews them daily to ensure quality. He recently launched an SEO podcast to separate AI and SEO content, and it quickly gained 2,000 views on a video, showing the power of targeted content.
