Token Counter API: The Ultimate Solution for Managing GPT, Claude, and Gemini Context Windows

This new Token Counter API is a fantastic and highly practical tool for developers working with multiple Large Language Models (LLMs). By accurately tracking token usage across OpenAI, Anthropic, and Google models in a single request, it brilliantly solves the constant headache of predicting API costs and avoiding context window errors. It's especially exciting to see a tool that perfectly handles the complexities of Japanese Natural Language Processing (NLP), making it an essential utility for global AI application development.
