Hy3 Destroys GLM 5.2?

GLM 5.2 vs Tencent Hunyuan HY3 (HY3): Side-by-Side Tests + Final Verdict

The script compares GLM 5.2 (from ZAI) versus Tencent Hunyuan HY3 (HY3) side by side using multiple generated projects, including game-like demos (Dragon Realm, flight sim, driving game, parachute game) and a Remotion cinematic video. HY3 is described as buggy, laggy, and often lacking detail, requiring hours of back-and-forth to get usable outputs, while GLM 5.2 generally produces smoother, more playable results on the first try. HY3 wins one round where GLM 5.2 fails, but GLM 5.2 wins 6 of 7 tests overall and also has a larger context window (1M tokens vs 256K). HY3’s advantages are free API access (via OpenRouter until July 21) and availability via Hermes Agent, while GLM 5.2 is preferred overall.

GLM 5.2 versus the new Tencent HY3. Who wins? I'm going to show you side by side the software we've built so far and how they perform and who wins so far. If you're wondering what's the difference between these two models well HY3 just dropped, GLM 5.2 dropped about two or three weeks ago and HY3 comes from Tencent Hanyu whereas for example GLM 5.2 comes from Zed AI.

You can get access to both of them for free so if you want free access to Tencent HY3 you can actually go to open router like so and it's free it's open source you can get a free API for it and it's available until July the 21st for free on open router. If you want to use GLM 5.2 for free you can actually get access via Zed.ai and then you get access right here. As far as I'm aware you can't get the API for free with GLM 5.2 but if you're wondering how do they perform side by side let me show you some of the examples right here. So the first test we ran here was with GLM 5.2 and Tencent Hanyu.

So this is the example from Tencent Hanyu and one of the things that I will say here is like it's pretty buggy when you're trying to navigate around but it doesn't look bad. Now we did have to go back and forth with this a lot to use it but again you can see it's almost unplayable like in terms of the way it's just difficult to navigate anything else. If we have a look at GLM 5.2's creation for the same model and test let's have a look here. So this is a lot smoother a lot easier to use the graphics are not quite as nice but it still can create something decent and it's much easier to navigate and play.

So I would say GLM 5.2 won that round for sure and let's check out the next one. By the way these are both Chinese models so it's interesting to see that both models are open source and both have come out of China. Now this is GLM 5.2's attempt something called Dragon Realm which is kind of like a an open world 3d game right and it looks pretty cool like RPG game actually works really smooth nice graphics easy to move around you know that's that's a pretty good creation. Now let's have a look at hate and you can see here it's not quite smooth it doesn't feel quite as nice and also you see how you can't really uh you don't number one you don't really get many characters inside the game number two it feels a little bit laggy and slow so when we move around for example that light just bugs around a bit and also it's just not as enjoyable to play.

Now if you're wondering okay how did you test this so we got Fable 5 to test it and literally we were going back and forth with it for like three hours trying to get good outputs out of HY3 and just couldn't really get there you know it just wasn't quite smooth that's the thing that I found is like GLM 5.2 just first time round it will give you better outputs than using HY3 so if you look at both of these rounds GLM 5.2 definitely won. Let's have a look at the next one so we've got a flight simulator here so this is the version from GLM 5.2 kind of interesting like first person um terrain is not bad easy to navigate easy to use to move around etc um looks pretty cool. Now let's have a look at the version from HY3 which begins pretty nicely and then kind of goes a bit wild like once you've flown up in the air you can't really do anything and the terrain just totally disappears all the detail disappears it's kind of a weird vibe so I would say again it just doesn't feel quite as detailed and fun to play as GLM 5.2. Next up we have this driving game so we can drive around a city a neon city it's called and this is the version from GLM 5.2 pretty fun to use still basic but it works and we can navigate around it's pretty smooth there's other cars in there it comes up with like pop-ups on the text as well and we've got a bit more detail here as well all right now let's have a look at that compared to HY3's output so you can see HY3 here lacks detail is a little bit buggy it just kind of feels a bit more dull I mean like if you look at the colors and everything else it works but again it's not it just feels more basic feels like an older generation versus GLM 5.2 so on every single round that I'm seeing GLM 5.2 is beating HY3.

Let's test the next one now this one is actually totally buggy from GLM 5.2 to be fair so I would say GLM 5.2 totally failed this task let's have a look at the generation from HY3 and that actually works now it's still a little bit buggy it still lacks detail which we've seen in pretty much every generation but it works so it beats GLM 5.2 on that round so for recap so far one two three four to GLM 5.2 HY3 has won the other generations then we've got two more to test so here we have like a parachute game where we can jump out of the plane and then we just have to aim for the section over there all right so that's GLM 5.2 and then if we have a look the generation from I mean this it doesn't really look like a parachute and there's no detail on the ground either so I would say HY3 won that sorry GLM 5.2 won that one and then finally we've got a cinematic style video advert this generated with Reemotion so we've created the same video with and with HY3 and we can see here GLM 5.2 snubbed so it's created like this nicely designed video and if we have a look we've got the other version from HY3 here which I mean the colors are not quite as rich doesn't look quite as nice but it still works it's an actual video it's purely using HY3 so it's pretty amazing itself that the AI can do this and we can use the API which is free as well so this is generated with a free open source skill called Reemotion so overall I would say GLM 5.2 won that round but didn't fail completely I could did a decent job so if we have a look at the rounds in total GLM 5.2 won one two three four five six rounds and HY3 won one round so overall and also one thing to note here is GLM 5.2 has a bigger context window at 1 million tokens versus HY3 which is 256k tokens I would say that the best open source model right now is still GLM 5.2 from ZAI however having said that there's two key benefits to HY3 number one you can go to it for free using the API which you can't do with GLM 5.2 and then also you can get it for free with Hermes agent if you go to news portal and then select your model provider as HY3 so there's two benefits there and two good options you know test out yourself that's why we created GoldieBench because we stopped listening to benchmarks and either way you can use them together inside an agent operating system like you've seen today so if you want to get the model the most out of both models you can plug them into your agent operating system test them out for yourself and see what you think but overall if I had a choice I would definitely go with GLM 5.2 I think that's still absolutely crushing and I can't wait to see what GLM 5.3 comes out with so thanks for watching if you want to get a full agent operating system with all these agents plugged in with all our best systems all our best fair trade the memory then you can get that inside the AI Profitable Boarding link in the comments description or go to the AI Profitable Boarding.com every time something new and useful drops like HY3 we test it out we try it with different projects we see what we can get out of it and we compare it versus everything else and if you have any questions you can post inside the community get help and support in real time if you want to get our agent operating system you can get that inside the classroom here and then you can see we have new daily video tutorials and inside the classroom too we have a beginner to expert AI automation course here if you want to ask questions jump on a call share your screen in real time etc you can do that here inside the calendar we have four coaching calls a week and then inside the map you can meet people in your local area who are building with AI agents like you so feel free to get that link in the comments description or just go to the AI Profitable Boarding.com final verdict GLM 5.2 wins HY3 not bad but I think it still needs a lot of improvement thanks for watching
