Buffer isn't in workers

K

kyle•12/5/24, 1:49 AM

might have to do something here https://developers.cloudflare.com/workers/runtime-apis/nodejs/buffer/

Cloudflare Docs

The Buffer API in Node.js is one of the most commonly used Node.js APIs for manipulating binary data. Every Buffer instance extends from the standard Uint8Array

class, but adds a range of unique capabilities such as built-in base64 and hex encoding/decoding, byte-order manipulation, and encoding-aware substring searching.

codebamOP•12/5/24, 1:50 AM

nah I'll just keep using

Uint8Array.from(binaryString, (m) => m.codePointAt(0));

Uint8Array.from(binaryString, (m) => m.codePointAt(0));

Uint8Array.from(binaryString, (m) => m.codePointAt(0));

Uint8Array.from(binaryString, (m) => m.codePointAt(0));

I asked this in the wrangler chat, but am I the only one who has to re-auth/re-allow wrangler to access workers AI locally every hour or two?

C

codebamOP•12/5/24, 1:54 AM

I don't have that issue

C

codebamOP•12/5/24, 1:54 AM

oh wait locally?

C

codebamOP•12/5/24, 1:54 AM

I didn't even know it worked locally. never used to

I

Isaac McFadyen•12/5/24, 2:00 AM

It now calls out to the remote Workers AI endpoint when developing locally, yeah.

J

James•12/5/24, 2:16 AM

Yeah it works, but it's irritating how I gave to re-auth it a few times a day

Why can't I use workers ai with auth and api gateway?

    const response = await config.ai.run('@cf/black-forest-labs/flux-1-schnell',
      {
        prompt,
        steps: DEFAULT_STEPS
      },
      {
        gateway: { id: 'misu-ai' },
        extraHeaders: {
          Authorization: `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-authorization': `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-token': `Bearer ${config.aiGateway.apiToken}`
        }
      }
    )

    const response = await config.ai.run('@cf/black-forest-labs/flux-1-schnell',
      {
        prompt,
        steps: DEFAULT_STEPS
      },
      {
        gateway: { id: 'misu-ai' },
        extraHeaders: {
          Authorization: `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-authorization': `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-token': `Bearer ${config.aiGateway.apiToken}`
        }
      }
    )

    const response = await config.ai.run('@cf/black-forest-labs/flux-1-schnell',
      {
        prompt,
        steps: DEFAULT_STEPS
      },
      {
        gateway: { id: 'misu-ai' },
        extraHeaders: {
          Authorization: `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-authorization': `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-token': `Bearer ${config.aiGateway.apiToken}`
        }
      }
    )

    const response = await config.ai.run('@cf/black-forest-labs/flux-1-schnell',
      {
        prompt,
        steps: DEFAULT_STEPS
      },
      {
        gateway: { id: 'misu-ai' },
        extraHeaders: {
          Authorization: `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-authorization': `Bearer ${config.aiGateway.apiToken}`,
          'cf-aig-token': `Bearer ${config.aiGateway.apiToken}`
        }
      }
    )

works if i do it without api gateway. with api gateway everytime i get an unathorised error. i have done it with just this header cf-aig-authorization and all the other headers on their own. I am doing open ai requests through my gateway its just workers ai. 0 examples in the dcos doing config.ai.run with an auth tokens. i just assumed i would add the auth to the extra header or something

Need help with Cloudflare Vectorize + Workers AI embedding query. Getting 'invalid query vector, expected 768 dimensions, and got 0 dimensions' despite vector data being present. Here's my code:

const embedding = await env.AI.run('@cf/baai/bge-base-en-v1.5', {
  text: query
});

const values = Array.from(embedding.data[0]);
const results = await vectorIndex.query({
  topK: 5,
  values: values
});

const embedding = await env.AI.run('@cf/baai/bge-base-en-v1.5', {
  text: query
});

const values = Array.from(embedding.data[0]);
const results = await vectorIndex.query({
  topK: 5,
  values: values
});

const embedding = await env.AI.run('@cf/baai/bge-base-en-v1.5', {
  text: query
});

const values = Array.from(embedding.data[0]);
const results = await vectorIndex.query({
  topK: 5,
  values: values
});

const embedding = await env.AI.run('@cf/baai/bge-base-en-v1.5', {
  text: query
});

const values = Array.from(embedding.data[0]);
const results = await vectorIndex.query({
  topK: 5,
  values: values
});

Logs show embedding.data[0] contains 768 values but query fails. Tried multiple query formats. Any suggestions?

Is hosting of custom models something that is expected to be a feature relatively soon for ai workers?

I

SuperHelpflare•12/7/24, 4:25 PM

Workers AI currently only supports popular open-source models provided by the Cloudflare team, as well as your own LoRAs that can be applied on top of the Cloudflare-provided models. You cannot currently upload your own models or use a model from HuggingFace. See the documentation for the list of Cloudflare-provided models: https://developers.cloudflare.com/workers-ai/models/

I

Isaac McFadyen•12/7/24, 4:25 PM

^ TLDR: probably not, no

B

Ben-xD•12/7/24, 10:29 PM

I noticed my friend has a workers AI page which shows usage, but mine doesn't. My friend did find a bug in the usage values though. It just shows "Welcome to Workers AI" on https://dash.cloudflare.com/$accountId/ai/workers-ai

Is the detailed workers page a feature being AB tested?

A

Aaron•12/7/24, 10:54 PM

is the workers ai limit charged per worker

A

Aaron•12/7/24, 10:54 PM

or is it global

A

Aaron•12/7/24, 10:55 PM

in other words i have 10 workers

A

Aaron•12/7/24, 10:55 PM

is the effective limit 3200 per minute

A

Aaron•12/7/24, 10:55 PM

vs 320 per minute across 10 workers

A

Aaron•12/7/24, 10:55 PM

320 per minute seemed pretty low

A

Aaron•12/7/24, 10:55 PM

for text generation

A

Aaron•12/7/24, 10:58 PM

sorry it's actually 300

If you're only using beta models they won't show usage.

Has anyone experienced this type error issue for the new models? Im following the tutorial pretty much to a tee thats at https://github.com/craigsdennis/punderful-workflows/tree/main.

It seems i only have access to the old models in autocomplete. Im using the latest @cloudflare/workers-types: ^4.20241205.0.

Tsconfig.json is the same as the punderful tutorial linked above:

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "Bundler",

    "lib": [

    ],
    "jsx": "react-jsx",
    "jsxImportSource": "hono/jsx"
  },
}

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "Bundler",

    ],
    "jsx": "react-jsx",
    "jsxImportSource": "hono/jsx"
  },
}

Is this an issue with the Workflows not having the right type definitions?

S

snoob•12/9/24, 10:46 PM

Im able to run the workflow no problem, Im in a turbo repo so probably messing something up

Oh interesting, the new models dont even work with typescript in that example either. LOL
