AI & LLM Calculators

Token counts, model memory, API costs, context windows — everything you need when working with large language models.

Token Calculator

Estimate token count from text length for any LLM model.

Calculate how much GPU memory a model needs based on parameter count.

Estimate LLM API costs based on token usage across major providers.

See how much text fits inside an LLM's context window.

Convert between FLOPS, TFLOPS, PFLOPS and GPU-hours.
