https://ai.cloudflare.com/#pricing-calculator You can check that here but there's no definite way to measure the usage of neurons or tokens based on individual queries. All we have is an estimate but no clear usage based metrics. Maybe in the birthday week next month they might change that or it'll just get ignored like most of the messages about token usage.
Beta models are free for now so they wont show up on pricing calculator

response should be Unit8Array not Response class, but problem it's read once (I guess), which causing

rajeev•8/30/24, 5:50 PM

Hi,
Not sure if this is the right place for this, but the docs directed me to this server

I was playing around with Workers AI text generation models and have found that setting

top_p

top_p

or

repetition_penalty

repetition_penalty

value to

causes

Cloudflare API Error

Cloudflare API Error

If we are using streaming then we directly get the

data: [DONE]

data: [DONE]

event,
if non-streaming then it is a

500 "Cloudflare API error"

500 "Cloudflare API error"

As per the docs the minimum allowed values for

top_p

top_p

&

repetition_penalty

repetition_penalty

is 0, so ideally we shouldn't get any error..

xav•9/3/24, 12:37 PM

Hey, I'm using llama-3.1-8b-instruct to classify and reject spam/inappropriate messages, it works mostly fine, but I'm struggling to reliably return a structured output (eg a json {"appropriate": boolean}).

X

xav•9/3/24, 12:39 PM

is there a trick beside finetuning the prompt and hope for the best? so far, asking to classify messages in other languages than english seems to trip the model (eg. it sometimes returns "approprié" as the key if the message is in french)

bge-large is a 1024-dimension model, so the vectorize index needs to be 1024 dimension as well. Looks like it's 768. bge-base is a 768-dimension model

I'm getting really horrible results with all of the text to image AI models (I've tried all of the ones CF has). I'm using the prompts below and getting garbage responses like those in this image.

Does anyone have suggestions on how to actually get what I want?

      negative_prompt: "There shOuld not be any other effects or images.",

Isaac McFadyen•9/7/24, 5:07 PM

This ^ plus SD uses CLIP for prompting which doesn't like natural language very much... comma seperated tags work better, for example:
Bad:

create me an image that is 512x512, with text that says "my text here" and a red background, with yellow text

create me an image that is 512x512, with text that says "my text here" and a red background, with yellow text

create me an image that is 512x512, with text that says "my text here" and a red background, with yellow text

create me an image that is 512x512, with text that says "my text here" and a red background, with yellow text
Good:

red background, text saying "my text here", arial font, yellow color

red background, text saying "my text here", arial font, yellow color

red background, text saying "my text here", arial font, yellow color

red background, text saying "my text here", arial font, yellow color

so...

let a = new Uint8Array(1)
console.log(JSON.stringify(a))

let a = new Uint8Array(1)
console.log(JSON.stringify(a))

it logs

{"0":0}

{"0":0}

{"0":0}

{"0":0}, but when i log the response from ai.run it's just

{}

{}

{}

{}

U

user•9/8/24, 11:06 AM

also, doing

console.log(res instanceof Uint8Array)

console.log(res instanceof Uint8Array)

console.log(res instanceof Uint8Array)

console.log(res instanceof Uint8Array) logs "false", so

I see CF use another metric called Neurons, but can’t find how it’s calculated on docs or any way t
