01What is GLM 5.2 vs HY3?
GLM 5.2 vs HY3 are two open-source AI models from China. GLM 5.2 comes from Z.ai, and HY3 is made by Tencent Hanyu. They can create games and videos from simple text prompts.
In this episode, Julian Goldie tests both side by side to see which one performs better.
The models are similar, but they have different strengths. GLM 5.2 feels smoother and easier to use. HY3 is newer and offers free API access.
Both are free to try, so you can test them yourself. The tests show a clear winner, but HY3 still has some good points.
02Main Features of GLM 5.2 and HY3
Both models can create playable 3D games and cinematic videos. They are open source, so anyone can use them for free. You can access them through different platforms.
GLM 5.2 is available on Z.ai, and HY3 is on OpenRouter.
- GLM 5.2 has a 1 million token context window, which is huge for handling long prompts.
- HY3 has a 256k token context window, which is smaller but still useful.
- HY3 offers a free API on OpenRouter until July 21, while GLM 5.2 does not have a free API.
- HY3 can also be used for free with Hermes agent through the news portal.
- Both models work inside an agent operating system, so you can combine them.
These features make it easy to compare and use both models. The bigger context window helps GLM 5.2 in complex tasks. The free API is a big plus for HY3 developers.
03How to Get Started with Both Models
Getting started is simple. Both models are free, but they use different platforms. Follow these steps to try them yourself.
- Go to Z.ai and sign up for GLM 5.2 access.
- Go to OpenRouter and get a free API key for HY3.
- For HY3 with Hermes agent, go to the news portal and select HY3 as your model provider.
- Test each model with simple prompts to see basic outputs.
- Use GoldieBench to run standardized tests if you want.
- Plug both models into an agent operating system to use them together.
That's it. You can start generating games and videos right away. The free access makes it easy to compare them without cost.
Remember, HY3's free API is only until July 21, so hurry.
04How the Models Performed in Tests
Julian used a tool called Fable 5 to test both models. They spent three hours going back and forth with HY3, but it just didn't work well. GLM 5.2 gave better outputs on the first try.
That made a big difference in the tests.
For the first game, HY3 was buggy and hard to navigate. GLM 5.2 was smoother and easier to play. The graphics weren't as pretty, but it worked better.
So GLM 5.2 won that round. Next, they tried an open-world 3D game called Dragon Realm. GLM 5.2 looked cool and ran smoothly.
HY3 was laggy and didn't have many characters. GLM 5.2 won again.
Then came a flight simulator. GLM 5.2 had nice terrain and easy controls. HY3 started fine but lost detail in the air.
The ground disappeared, and it felt weird. GLM 5.2 won that round. For a neon city driving game, GLM 5.2 had more cars and text pop-ups.
HY3 lacked detail and felt older. GLM 5.2 won.
One test where GLM 5.2 totally failed was a buggy task. HY3 worked, even though it was still a bit buggy. So HY3 won that round.
In a parachute game, GLM 5.2 did better. The ground had detail, and it looked like a real parachute. HY3 didn't look like a parachute.
GLM 5.2 won.
Finally, they made a cinematic video with Reemotion. GLM 5.2 produced a nicely designed video. HY3's video had duller colors but still worked.
GLM 5.2 won that round. In total, GLM 5.2 won six rounds, and HY3 won one.
05Results and Comparisons: GLM 5.2 Wins
The final score is GLM 5.2 wins 6 out of 7 tests. HY3 only won one. Julian says GLM 5.2 feels better overall.
It is smoother, easier to use, and more detailed. HY3 has issues with lag and bugs.
But HY3 isn't a total loss. It has a free API, which GLM 5.2 lacks. You can use HY3 for free on OpenRouter.
That is a big advantage for developers who want to save money. HY3 also works with Hermes agent, adding another free option.
In terms of context window, GLM 5.2 has 1 million tokens, and HY3 has 256k tokens. That means GLM 5.2 can handle longer prompts. For tasks that need more memory, GLM 5.2 is better.
06Tips, Limits, and Mistakes to Avoid
When using these models, watch out for a few things. HY3 can be buggy and difficult to navigate. In the tests, they had to go back and forth a lot to get good outputs.
It took three hours with Fable 5 to get something decent. So be patient, but also know it may not be worth the time.
GLM 5.2 is more reliable on the first try. But it can fail sometimes, like in the buggy test. So don't expect perfection.
Also, remember that HY3's free API only lasts until July 21. After that, you may have to pay.
Another mistake is not using the context window to your advantage. GLM 5.2's 1 million tokens let you give it huge prompts. Use that to get better results.
For HY3, keep prompts shorter due to the smaller window.
07Who These Models Are For and Why They Matter
These models are for anyone who wants to create games or videos with AI. You don't need coding skills. You just type a prompt, and the model does the work.
They are great for developers who want to build apps with AI.
Because they are open source, you can use them freely. That lowers the cost of AI projects. You can even plug them into an agent operating system to work together.
That gives you the best of both worlds.
Two Chinese companies are leading this open-source movement. That's a big deal. It means AI progress is global.
These models show that free, open-source AI can be powerful. You should try them and see what you can build.
