Llm Numbers
llm-numbers is a set of calculation tools and benchmarks used to predict hardware requirements, token usage, and operational costs across various model tiers. It provides a cost and resource calculator based on formulas and benchmarks to estimate tokens, GPU memory, and operational expenses for large language models.
The project includes a hardware requirement planner for calculating the VRAM and GPU memory needed to host models based on parameter counts. It also features a token estimator that converts word counts into token estimates to predict API billing and context window usage, alongside pricing benchmarks that compare costs and throughput trade-offs between different hosting methods.
The toolset covers AI model benchmarking and cost forecasting, GPU resource planning, and performance analysis for measuring throughput gains from batching. It utilizes deterministic formulas and static benchmark datasets to map parameters to memory and calculate the cost-benefit ratios between base models and fine-tuning.
