Billion Parameters
The standard unit for expressing model scale, where larger usually means more capable.
Modern LLMs are described by their parameter count in billions (B). A 7B model is fast and cheap to run locally; a 405B model rivals frontier closed APIs but requires substantial GPU clusters. Parameter count is a rough proxy for capability — architecture, training data quality, and fine-tuning often matter more than raw size.
