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

Most likely its training data included countless Space Invaders in various programming languages.

This comment is ~3 years late. Every model since gpt3 has had the entirety of available code in their training data. That's not a gotcha anymore.

We went from chatgpt's "oh, look, it looks like python code but everything is wrong" to "here's a full stack boilerplate app that does what you asked and works in 0-shot" inside 2 years. That's the kicker. And the sauce isn't just in the training set, models now do post-training and RL and a bunch of other stuff to get to where we are. Not to mention the insane abilities with extended context (first models were 2/4k max), agentic stuff, and so on.

These kinds of comments are really missing the point.

You are reading too much into my comment. My point was that the test (a Space Invaders clone) used to asses the model is irrelevant for some time now. I could have gotten a similar result with Mistral Small a few months ago.
