My 2.5 year old laptop can write Space Invaders in JavaScript now (GLM-4.5 Air)

Aside that space invaders from scratch is not representative for real engineering, it will be interesting to see what the business model for Anthropic will be if I can run a solid code generation model on my local machine (no usage tier per hour or week), let’s say, one year from now. At $200 per month for 2 years I can buy a decent Mx with 64GB (or perhaps even 128GB taking residual value into account)

How come it's "not representative for real engineering"? Other than copy-pasting existing code (which is not what an LLM does), I don't see how you can create a space invaders game without applying "engineering".

Making a space invaders game is not representative of normal engineering because you're reproducing an existing game with well known specs and requirements. There are probably hundreds of thousands of words describing and discussing Space Invaders in GLM-4.5's training data

It's like using an LLM to implement a red black tree. Red black trees are in the training data, so you don't need to explain or describe what you mean beyond naming it.

"Real engineering" with LLMs usually requires a bunch of up front work creating specs and outlines and unit tests. "Context engineering"
