LLM pricing and token tools

Prices, context windows and release dates for current models from OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral, Meta and Qwen, read from each vendor's own pages. Count tokens, size a context window, and estimate the cost of a prompt, an agent run or a whole workflow before you ship it.
