See this: https://developers.cloudflare.com/workers-ai/features/function-calling/

Hi folks! What's the best way to do embedded function calling through an AI Gateway (e.g. to enable caching)?

It looks like cloudflare/ai-utils doesn't let us pass in a

(as shown in the AI Gateway docs: https://developers.cloudflare.com/ai-gateway/providers/workersai/#workers-binding)

Though I'm not sure where to find detailed documentation on the AI binding — the docs don't say anything useful about the second parameter object: https://developers.cloudflare.com/workers-ai/configuration/bindings/#methods

The TypeScript types seem to have the best information. But still, it doesn't seem like AI binding / gateway /

nick•4/30/25, 4:20 AM

For the text-to-image models such as flux-1-schnell the current output is simply:

{ image: string }

{ image: string }

is there a way to have it output the usage data, similar to the

{ usage: { prompt_tokens: number, completion_tokens: number, total_tokens: number }}

{ usage: { prompt_tokens: number, completion_tokens: number, total_tokens: number }}

output for text generation models? Based on the pricing, I'd assume it would be something like

{ usage: { tiles: number, steps: number }}

{ usage: { tiles: number, steps: number }}

? Or does this just need to be calculated on each usage on our end using the default step of 4 if none is provided as input, and measuring the output image size?

Regarding output image size. Is there or will there be a way to specify the desired image output resolution? The image size i'm getting back is 1024x1024, so four 512x512 tiles. Just want to confirm this will always be the case?
