FAQ

What are LLMs?

LLMs are a type of artificial intelligence that excel at understanding and generating human-like text. They are trained on massive amounts of text data, enabling them to perform tasks like translation, summarization, and creative writing.

What is Tokenization?

Tokenization is the process of breaking down text into individual units called "tokens." Tokens can be words, punctuation marks, or even sub-word units like morphemes. LLMs rely on tokenization to represent text data in a way they can understand.

What is Quantization?

Quantization is a technique used to reduce the size of LLM models and speed up their inference process. It involves converting high-precision numbers (like floating-point numbers) into lower-precision representations (like integers). This smaller size allows for faster computation without sacrificing too much accuracy. For example, a 10-bit quantized model could represent the same information with fewer bits than a 32-bit floating-point model.

Are GPUs always better than CPUs for LLMs?

Not necessarily. CPUs can be more efficient for smaller LLMs, especially when using quantized models. GPUs excel with larger LLMs that require FP16 computations. Ultimately, the best choice depends on the specific model and workload.
