Oddly, I don't see anything about pricing for Workers AI on the Workers pricing page[0] but their Workers AI blog post from Sept 2023[1] says the pricing is per 1k "neurons":
> Users will be able to choose from two ways to run Workers AI:
> Fast Twitch Neurons (FTN) - running at nearest user location at $0.125 / 1k neurons
> Neurons are a way to measure AI output that always scales down to zero (if you get no usage, you will be charged for 0 neurons).
Here's the key detail:
> To give you a sense of what you can accomplish with a thousand neurons, you can: generate 130 LLM responses, 830 image classifications, or 1,250 embeddings.
productionizing ai models is a pain, this makes it easy. say you were building a d&d app and wanted to generate character art, this would make it very easy to get started. aws has similar offerings (e.g sage maker) but it’s not on the edge.
