Calculate Token Usage and
API Costs for 400+ LLMs

While building with LLMs, engineers should neither spend time counting tokens
nor fret about cost estimation.

Unstract’s Token Calculator tool lets you calculate and compare costs for OpenAI, LLaMA, Claude, Gemini and other popular models.

Why keeping track of token count is important

LLM cost management

Many LLM APIs charge based on the number of tokens processed. Calculating tokens helps manage and predict costs, especially for large-scale or commercial applications.

LLM token limit handling

Most LLMs have a maximum context length measured in tokens. Some models might have a limit of 2048 or 4096 tokens. Knowing the token count helps ensure that inputs do not exceed these limits, as the model may not process inputs beyond this length effectively.

Performance and latency

Understanding token counts can help optimize the performance of LLMs. Token-heavy requests can increase latency (response time) and computational load. Minimizing token usage improves processing speed and user experience.

Efficient prompt engineering

Crafting effective prompts often involves managing token counts to include all necessary information without exceeding model limits. This is particularly important for complex tasks that require detailed instructions.

Evaluation and benchmarking

In research and development, token counts are used to evaluate model performance and compare different models. Standardized token counts help ensure that evaluations are fair and comparable.

Output Completeness

Consistent token counts can help maintain consistency in the model's responses. If an LLM is expected to generate structured outputs — like summaries or JSON objects — the response might be incomplete if it exceeds token limits.

Why did we build a Token Calculator?

At Unstract, we focus on leveraging LLMs to automate document extraction. Effectively managing tokens is crucial for controlling costs, performance, and output quality—particularly in complex document extraction workflows. These processes often involve large inputs, requiring predictable and cost-efficient results.

Unstract is the leading open source IDP 2.0 platform that fully leverages LLMs for structured document data extraction from unstructured documents.
