This is a more generic AI/LLM question, tokens are their sort of base building blocks, not always matching up with a single word: https://www.johno.com/tokens-vs-words

Thank you!
But for example, if I used only latin and symbols, how much would a token be?

C

Chaika•1/6/25, 12:33 AM

Depends on the model you use/it's tokenizer

C

Chaika•1/6/25, 12:35 AM

For example, OpenAI's tokenizers are like this: https://platform.openai.com/tokenizer, cool visulization to play around with

one for a model that is on Worker's AI, Lllama 3's https://lunary.ai/llama3-tokenizer

Raylight•1/16/25, 9:41 AM

The file size limit was roughly 2.6MB last time I tested, but it depends on the content and whether or not it's supplied as a JS array. See workers-ai. If it's possible to use base64, the limit should be higher. I haven't tested it, though.
