What you get from the API is guaranteed to be valid JSON, but if you ask a LLM to reply with JSON (inside the

I'm trying to use Cloudflare worker-AI with langchain to embed some text. Specifically I'm trying to use the

OpenAIEmbeddings

OpenAIEmbeddings

OpenAIEmbeddings

OpenAIEmbeddings library to send text to my AI-worker. What I noticed is that the

embed_documents

embed_documents

embed_documents

embed_documents method doesn't send the text to the endpoint provided but rather sends an array of tokens. On the other hand the CF embedding models/methods expects strings as inputs. Anyone know how to resolve this? Is there specific Langchain library for Cloudflare, or is there a way to input tokens into the CF models?

C

celeste_y•10/28/24, 2:44 AM

In my application, I need to create embeddings for articles and queries in both Chinese and English. However, the embedding models supported by Worker-AI are English-only models. I am thinking about calling out to an external inference API which supports multi-lingual embedding, then insert into/ query the embedding with Cloudfare Vectorize. Before doing that, I want to check and see if there is a more cloudfare native way to support multi-lingual embedding as I would like to keep my whole workflow on Cloudfare if possible. Thank you!

pcnoic•10/28/24, 4:41 PM

Hey folks, we're having a weird issue that may or may not be a direct result of the way we're trying to leverage the AI binding in our worker.

We're using the application context to inject the various instances of Cloudflare bindings (we've done this for KV, R2 and multiple other services and now trying for AI).

import { useContext } from '@fc/core/context';

/**
 * Injects the Ai instance into the application context.
 */
export const withAI = (ai: Ai) => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: ensure the AI binding is attached.');
  }
  context.dependencies.set('ai', ai);
};

/**
 * Retrieves the Ai instance from the context.
 * Throws an error if Ai is not found.
 */
export const useAI = (): Ai => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: useAI must be called within a Cloudflare Worker.');
  }
  const ai = context.dependencies.get('ai') as Ai;
  if (!ai) {
    throw new Error('AI instance not found in context. Ensure `withAI` is used.');
  }
  return ai;
};

import { useContext } from '@fc/core/context';

/**
 * Injects the Ai instance into the application context.
 */
export const withAI = (ai: Ai) => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: ensure the AI binding is attached.');
  }
  context.dependencies.set('ai', ai);
};

/**
 * Retrieves the Ai instance from the context.
 * Throws an error if Ai is not found.
 */
export const useAI = (): Ai => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: useAI must be called within a Cloudflare Worker.');
  }
  const ai = context.dependencies.get('ai') as Ai;
  if (!ai) {
    throw new Error('AI instance not found in context. Ensure `withAI` is used.');
  }
  return ai;
};

import { useContext } from '@fc/core/context';

/**
 * Injects the Ai instance into the application context.
 */
export const withAI = (ai: Ai) => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: ensure the AI binding is attached.');
  }
  context.dependencies.set('ai', ai);
};

/**
 * Retrieves the Ai instance from the context.
 * Throws an error if Ai is not found.
 */
export const useAI = (): Ai => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: useAI must be called within a Cloudflare Worker.');
  }
  const ai = context.dependencies.get('ai') as Ai;
  if (!ai) {
    throw new Error('AI instance not found in context. Ensure `withAI` is used.');
  }
  return ai;
};

import { useContext } from '@fc/core/context';

/**
 * Injects the Ai instance into the application context.
 */
export const withAI = (ai: Ai) => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: ensure the AI binding is attached.');
  }
  context.dependencies.set('ai', ai);
};

/**
 * Retrieves the Ai instance from the context.
 * Throws an error if Ai is not found.
 */
export const useAI = (): Ai => {
  const context = useContext();
  if (!context) {
    throw new Error('Context not found: useAI must be called within a Cloudflare Worker.');
  }
  const ai = context.dependencies.get('ai') as Ai;
  if (!ai) {
    throw new Error('AI instance not found in context. Ensure `withAI` is used.');
  }
  return ai;
};

We setup a

withAI

withAI

withAI

withAI and

useAI

useAI

useAI

useAI method that allows us to inject the binding instance into our workers from a core package.

We would then do something along the lines of:

 await withContext(requestId, async () => {
    const env = envSchema.parse(_env);

    // AI
    withAI(_env.AI);

 await withContext(requestId, async () => {
    const env = envSchema.parse(_env);

    // AI
    withAI(_env.AI);

 await withContext(requestId, async () => {
    const env = envSchema.parse(_env);

    // AI
    withAI(_env.AI);

 await withContext(requestId, async () => {
    const env = envSchema.parse(_env);

    // AI
    withAI(_env.AI);

Where the

Env

Env

Env

Env interface was generated by

wrangler types

wrangler types

.

Our

_env.AI

_env.AI

_env.AI

_env.AI in this case is of

 abstract class Ai

abstract class Ai

 abstract class Ai

abstract class Ai as defined in the workers-type pacakge.

But, when we try to do something similar to in a service:

const cloudflareJobOutput = (await ai.run('@cf/openai/whisper', modelInput)) as WhisperResponse;

const cloudflareJobOutput = (await ai.run('@cf/openai/whisper', modelInput)) as WhisperResponse;

const cloudflareJobOutput = (await ai.run('@cf/openai/whisper', modelInput)) as WhisperResponse;

const cloudflareJobOutput = (await ai.run('@cf/openai/whisper', modelInput)) as WhisperResponse;

we catch an error which is hard to debug

No documentation I can find and only this community entry -> https://community.cloudflare.com/t/inferenceupstreamerror-for-large-audio-files-2-mb/624759/6?u=fry69 pointing at a ~2MB limit (at least for whisper), which is tiny. I wonder if there is another way to reference objects to include for AI inference.

Otherwise, I'd deal with this limit and try to transform images to a smaller fixed size before sending them (I think APIs like e.g. Gemini do this internally to a 256x256 size anyway)

The limit is "fuzzy". Around 2.5-3MB depending on the content. Seems to apply to all models. (

JSON.stringify(inputs).length

JSON.stringify(inputs).length

JSON.stringify(inputs).length

JSON.stringify(inputs).length needs to be less than 9.5 MB, to be precise. I.e. the input to AI.run is stringified at one point internally and must not exceed ~10 million bytes or you'll get "request to large". cc @Kristian)
