AiPrice – API for Accurate OpenAI Prompt Pricing (aiprice.dev)

The API doesn't even follow the format that OpenAI's chat endpoints take. You don't pass a single string to them. You pass an array of system/user/assistant messages. So this pricing won't be accurate

Not to mention this would be better replaced with a tokenizer lib and a multiplication operation

I don't think a frontend for tiktoken is worth a monthly subscription

To be honest, with an effectively anonymous website, this feels like an operation to gather other people’s prompts.

> The calculating method is based on the latest available pricing data released by OpenAI at https://openai.com/pricing. However, please note that actual costs may vary and we cannot guarantee the price.

I guess in that case we can just use this as reference and calculate it by yourself

From https://help.openai.com/en/articles/4936856-what-are-tokens-...

1 token ~= 4 chars in English

1 token ~= ¾ words

100 tokens ~= 75 words

Or

1-2 sentence ~= 30 tokens

1 paragraph ~= 100 tokens

1,500 words ~= 2048 tokens
