How LLM Context Calculator Works
A Context Window Calculator is an AI resource utility used to check if your text fits inside a Large Language Model (LLM). This tool is essential for developers, researchers, and power users planning RAG pipelines, estimating API costs, and choosing the right model for long documents.
Model Database: Compares your count against limits for GPT-4, Claude 3, Llama 3, and Gemini.
Cost Estimator: Projects the API cost for processing that many input tokens.
