Token Estim8r: Track AI Model Token Usage & Costs

This n8n sub-workflow, Token Estim8r, enables precise tracking of token usage and costs for AI models like OpenAI and Anthropic directly within your workflows. It uses an Execute Workflow node to analyze inputs, estimate tokens, fetch live pricing from JinaAI (or static rates), compute total costs, and append data to a Google Sheet with timestamps and model details.

Ideal for AI engineers, automation specialists, and analysts, it solves the challenge of opaque LLM spending by providing real-time visibility. Whether prototyping or in production, avoid budget overruns with automated logging—no more manual calculations or surprise bills.

Benefits include support for multiple models, optional live pricing, easy integration via sub-workflow calls, and customizable sheets for dashboards. Use cases: monitor chatbots, RAG pipelines, or batch generations; integrate into dev tools for cost-optimized AI automation.

Setup is straightforward: create a Google Sheet with provided headers, configure credentials, and trigger from any workflow for instant insights.
