Count tokens for any text with tiktoken-compatible encoders, then estimate USD cost across 20+ LLM models (OpenAI GPT-4o/o1/4.1, Anthropic Claude Opus/Sonnet/Haiku 4.x, Meta Llama 3, Google Gemini 1.5, Mistral, DeepSeek). Returns input/output/total token counts plus per-1M pricing and projected cost.
