What does a conversation cost?
Models charge per token, a chunk of text about four characters long. You can paste your own text below to see what it would cost on every model.

What you'd send the model: a question, a document, a prompt.
A stand-in for the model's reply. Edit it to match how long you expect answers to be.
Token counts use OpenAI's o200k tokenizer. Other providers split text slightly differently, so treat their counts as close approximations.

Not shown (Inkling, Mistral Medium 3.5, GLM-5.2, DeepSeek V4 Pro, Qwen 3.6, Llama 4 Maverick, Llama 4 Scout): open-source models are free to download and run on your own hardware, so there's no fixed per-token price to calculate. Hosted-API pricing for them varies by vendor.
Price per million tokens
Output tokens cost several times more than input tokens on every model. Open-source models aren't shown. They're free to download, so there's no fixed per-token price.
