Workers AI pricing is all kinds of confusing right now. Docs talk about tokens which is the “new” method that was set to go into action on November 1st but never happened, dashboard talks about neurons, old marketing talks about neurons, etc.

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

Llord5et What is the file size limit when it comes to @cf/openai/whisper model?

R

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.

Hey, the docs are sorta confusing, Are we able to pay for more neurons? If so, is it monthly, could
