LLM training costs estimated via simple formula and GPU-hour calculations · 1 source tracked

Training a large language model involves calculating the total computational cost, which can be estimated using a simple formula: 6 times the number of parameters multiplied by the number of tokens. This formula, derived from the operations required per token, has been validated against models like Chinchilla and Meta's Llama-3.1-405B. The actual cost in GPU hours depends on the speed achieved by the hardware, with NVIDIA H100s typically operating at 40% of their peak performance during real-world training. This calculation provides an order-of-magnitude estimate, but actual dollar costs can vary significantly based on GPU rental prices and do not include expenses from experimentation or smaller model development.
