💡 How Token Estimation Works
Large Language Models process text using Tokens. A helpful rule of thumb is that 1 token is approximately 4 characters or 0.75 words for English text. For CJK (Chinese, Japanese, Korean) characters, 1 character typically consumes 1 to 2 tokens. This tool utilizes a heuristic algorithm based on character sets to provide blazing-fast, client-side estimations.
💰 Why Estimate API Costs?
When building automated AI content pipelines or matrix publishing workflows, unbounded prompts can lead to unexpected billing shocks. By utilizing this tool during development, you can easily compare pricing tiers (e.g., discovering the high cost-efficiency of models like DeepSeek for bulk text generation) and optimize your prompt engineering strategy.
