01What Tencent Hanyuan HY3 free agent is and how it works

Tencent Hanyuan HY3 free agent is a new 295 billion parameter mixture-of-experts (MOE) model from Tencent that you can run for free inside Hermes Agent for two weeks. It is a generative model with a 256k context window, and it is specifically designed for agentic workflows, meaning it can handle tasks like coding, tool use, and reasoning.

This model was just released a few hours ago, and Tencent made it free on Noose Portal for a limited time. You can also get a free API key through OpenRouter. With these options, you can plug HY3 into Hermes Agent and use it as the brain for your AI tasks.

02Key features of Tencent Hanyuan HY3

Tencent Hanyuan HY3 comes with several features that make it useful for AI agents:

  • 295B MOE architecture – It uses a mixture-of-experts design, which means it is large but efficient.
  • 256k context window – It can handle long conversations and large amounts of text.
  • Agentic design – It is built for reasoning and tool use, perfect for AI workflows.
  • Open source – The model is open source, so you can access it freely.
  • Free access – It is free for two weeks on Noose Portal, and also free on OpenRouter and Kilo Code.

These features make it a good option for testing and building AI agents without spending money.

03How to set up Tencent Hanyuan HY3 with Hermes Agent

Setting up Tencent Hanyuan HY3 with Hermes Agent is simple and non-technical. Follow these steps:

  1. Open your terminal.
  2. Type Hermes model to open the model selection.
  3. Select Noose Portal at the top of the list.
  4. Choose Tencent HY3 from the available models.
  5. If you prefer the API route, go to OpenRouter and select Tencent HY3.
  6. Copy the API key and plug it into Hermes Agent.

You can also use HY3 directly in Kilo Code for free. No technical skills are needed—just a few terminal commands.

04How to use Tencent Hanyuan HY3 in Hermes Agent

Using Tencent Hanyuan HY3 in Hermes Agent is straightforward. In the episode, Julian gave it a task to code a beautiful landing page. The model provided a link to the page, which looked pretty nice and took about 60 seconds to build.

You can also use tool use with HY3. For example, you can ask it to open a website, and it will do it. Another feature is the /learn command.

You can type /learn and give it a link to a guide, and it will read the page, provide a breakdown, and save what it learned as a skill for future workflows.

Here’s a simple way to use it:

  • Give it a coding task like building a landing page.
  • Ask it to use tools, like opening a website.
  • Teach it new skills with /learn.

It works in three steps: plug Hermes into your AgentOS, use Noose Portal or OpenRouter for two weeks, and let HY3 act as the brain.

05Performance results and comparisons for HY3

In the episode, Julian tested Tencent Hanyuan HY3 with a coding task. The model built a full landing page in about 60 seconds, which he described as pretty nice and fairly responsive. It was not at the level of Fable 5, but it was good for a free model.

Julian also compared HY3 with Opus and Fable models. In his own tests, HY3 was nowhere near the same level as Opus 4.8 or Fable 5. He mentioned that you can see the outputs on GoldieBench if you want to check.

Another test used the /learn command. It took about 30 seconds to read a page and provide a breakdown. That is decent speed for a free model.

Overall, HY3 performs well for basic coding and agent tasks, but it is not a frontier model.

06Tips, limits, and mistakes to avoid with HY3

When using Tencent Hanyuan HY3, there are a few things to keep in mind:

  • Rate limits – If you get rate limited or throttled, you can switch to another free model like OmniRoot.
  • Speed – Each response can take about 60 seconds, so be patient.
  • Two-week window – The free access is only for two weeks, so use it now.
  • Quality – It is not as good as premium models like Opus 4.8 or Fable 5.
  • Token usage – Use an agent operating system to delegate subtasks to HY3 and save tokens.

One common mistake is thinking it’s not free. But Hermes Agent is free and open source, and HY3 is free on OpenRouter and Noose Portal. You can also use it in Kilo Code.

07Who should use Tencent Hanyuan HY3 and why it matters

Tencent Hanyuan HY3 is for anyone who wants to use a powerful AI model without paying. It is especially useful for developers, content creators, and AI enthusiasts who want to test agentic workflows.

Because it is free for two weeks, you can experiment with coding, tool use, and learning new skills without risk. It also works well in an agent operating system, where you can delegate subtasks to HY3 and use a stronger model as the main brain.

This model matters because it shows that open source and free models are getting better and more capable. Even though it is not as strong as frontier models, it is a good option for many tasks.

08Other ways to access Tencent Hanyuan HY3

Besides Noose Portal and OpenRouter, you can access Tencent Hanyuan HY3 inside Kilo Code. This gives you another free option for using the model.

There is also an HY3 Coda available. This lets you plug in the free API from HY3 and use it with Tencent directly. You can preview what you build and use it with Hermes or directly in the Coda.

These options give you flexibility. You can choose the setup that works best for you, whether you prefer a terminal, a web interface, or a coding environment.
