HOW LLMS SEE THE WORLD

LLMs see and process text through tokenization, breaking text into smaller units before converting them into numerical representations. Common tokenization methods include BPE, WordPiece, and SentencePiece. The method of tokenization can impact costs, context limits, and model performance in areas like non-English languages and mathematical reasoning.

WHY LLMS CAN'T REALLY BUILD SOFTWARE

LLMs can't truly build software. While LLMs are great at generating and updating code, they struggle to maintain clear mental models of code and requirements, leading to confusion and flawed decision-making. This limitation is due to issues like context omission, recency bias, and hallucination, preventing LLMs from properly iterating towards working solutions for complex tasks.

YOUR MAC GAME IS PROBABLY RENDERING BLURRY

Many Mac games on notched displays render blurry due to using the wrong resolution, drawing to the entire screen instead of the area below the notch. The `CGDisplayCopyAllDisplayModes` function returns resolutions for both the full display and the usable area under the menu bar, but games often default to the former, causing a compressed image. A solution is to filter the resolution list using `safeAreaInsets` to find resolutions fitting within the usable area.

DO WE UNDERSTAND HOW NEURAL NETWORKS WORK?

While we understand the mathematical code and training processes behind modern neural networks like LLMs, we don't have a deep understanding of how they achieve specific results or the complex statistics they derive from data. We can reverse engineer some specific functions, like identifying a "Golden Gate Bridge" neuron or how arithmetic is performed, but these are limited and often surprising. The end result of training is a vast, interconnected web of statistics that is difficult to comprehend, and it is hard to determine in advance what poem an LLM will write by looking at the training code.
