Should workers be compatible with transformers.js yet? I've tried setting it up, hoping to cache everything in KV after the first request! But I can't seem to pull the wasm files. Docs say you should be able to load from the jsdelivr cdn instead of trying to pull from /public, which I thought would work for Workers but I'm getting

Error: no available backend found. ERR: [wasm] RuntimeError: Aborted(both async and sync fetching of the wasm failed)

If you're trying to load WASM at runtime from JSDelivr that won't work in Workers.

I

Isaac McFadyen•5/13/24, 4:25 AM

Workers intentionally don't support dynamically loading WASM for security reasons, it must be uploaded at deploy time.

hey guys... iam loving the CF hosted Workers AI inference and all the models! I have a few questions:
1/ what is the pricing for beta mode models?
2/ what does it mean by it is in "beta"? CF wont pull the plug on the model I assume?
3/ are beta models suitable for staging type situations? ie not exactly prod, but close

A

Andus•5/13/24, 8:30 AM

Hi. When I'll end my limit from Workers Free will cloudflare start the paid pricing automatically or do I need to enable it myself? If it starts automatically can I turn it off somehow?

R

rob•5/13/24, 12:13 PM

Beta models are free rn afaik

J

James•5/13/24, 1:42 PM

It's quite disappointing to see the AI team's approach to backwards compatibility thus far, going against all of the great paradigms the Workers runtime has enforced for years.

Some examples:

https://github.com/cloudflare/workerd/pull/2044
- it took me quite some time to argue the point about this being a breaking change, despite pushback from multiple team members and saying the risk was "non-existent". Turns out, after this was merged, it broke things and had to be partially reverted
https://github.com/cloudflare/workerd/pull/2103#discussion_r1598483980
- another recent example that was just merged. I truly hope this doesn't break anyone's applications when it rolls out

As a long-time Workers user, I'm a massive fan of their compat guarantees as outlined at https://blog.cloudflare.com/backwards-compatibility-in-cloudflare-workers, and it seems the AI team isn't taking this very seriously for a GA product. There's precedent for other bindings implementing breaking changes behind compat flags, too: https://github.com/cloudflare/workerd/pull/1297

A change to the Workers Runtime must never break an application that is live in production.

.neurorotic.•5/13/24, 4:21 PM

The docs seem out of date, there is no "Account details section contains your Account ID" section on workers and pages ->overview https://developers.cloudflare.com/fundamentals/setup/find-account-and-zone-ids/#find-account-id-workers-and-pages
And the only way I found to find it is by creating a domain (even though I did not intend to register any w/ CF) but then finally noticed the account_id is after the dash.cloudflare.com/{ACCOUNT_ID}/ on the site

This could be much clearer for first-time users.

J

James•5/14/24, 11:17 PM

you'd probably want to just:

try {
    await env.AI.run(...)
} catch (e) {
    return new Response('handle errors here')
}

try {
    await env.AI.run(...)
} catch (e) {
    return new Response('handle errors here')
}

try {
    await env.AI.run(...)
} catch (e) {
    return new Response('handle errors here')
}

try {
    await env.AI.run(...)
} catch (e) {
    return new Response('handle errors here')
}

and then consider retrying with errors if it makes sense.

J

James•5/14/24, 11:18 PM

passThroughOnException

passThroughOnException

passThroughOnException

passThroughOnException is more intended for if you have an origin behind the worker

J

James•5/14/24, 11:18 PM

so that rather than showing an error page, it'll just send the request as-is to your origin. This is often referred to as a "fail-open" design
