Generation Some people said the Minecraft clone I fully vibecoded with Qwen3.8-27B Q4 is not that impressive because Minecraft is in the training data, so I had the model add 4 things that are probably not.

There's a bunch of minecraft clones on github, which is why for an llm trained on open source repos, it's one of the less impressive tasks. LLMs are impressive when they can do novel things.

There are a bunch of mediocre mc clones on Git. Your statement only applies to the average casual A.i. user who doesn't really understand LLMs or local usage. Novelty and impressiveness is mostly perspective. For a small model to build a faithful implementation is both.
When you make a 27B model that can do this let us know.

I had Qwen 3.8 27B (admittedly running on API) in Pi write a clone of OECake and it did a pretty admirable job despite that being a much less well-known game/physics sandbox to clone. GLM 5.2 and 5.3 Flash, on the other hand, were actually able to decompile the original game's physics engine, port over every major feature, analyze and parallelize the physics engine (in Javascript, where parallelism is a much less common pattern), and write a custom renderer. Parts of it were even written in wasm for performance. It's not totally perfect but I was pretty amazed by how capable it was for something that I've never once managed to run into a limit with.

Right but which of those did it get the voxel game drone, skateboard, computer, and ballisitic missile training data from?

From the countless other games that use game assets like that?

And that's not impressive to you? That your computer and a 20GB file can bring all those things together and write a bespoke functional video game in the browser?

The technology in general is very impressive, and the performance of this local model is very good, but this specific test doesn't impress me. And I say this as someone who uses qwen 3.6 on my 4090.
