then put in R2

env.MY_BUCKET.put(newImageName, response)

it works in 1.0.53
but It takes typeError in 1.1.0 when putting R2, with something about readable Stream, sorry about unclear error information because I rolled back version 1.0.53

acusti•3/17/24, 5:12 PM

it should be possible to improve the built-in @cloudflare/ai@cloudflare/ai types to narrow the return type based on the received streamstream variable (stream: truestream: true means ReadableStream<any>ReadableStream<any>, stream: falsestream: false means AiTextToImageOutputAiTextToImageOutput or the like), which would remove the need for this workaround.

that said, you can resolve the typescript errors by casting the return value instead of defining the variable type. so in your example, you would do:

const response = (await ai.run("@cf/stabilityai/stable-diffusion-xl-base-1.0", input)) as AiTextToImageOutput;

const response = (await ai.run("@cf/stabilityai/stable-diffusion-xl-base-1.0", input)) as AiTextToImageOutput;

if instead you were passing in stream: truestream: true to the ai.run(…)ai.run(…) function, you would want to cast the result to ReadableStream<any>ReadableStream<any>:

const response = (await ai.run("@cf/stabilityai/stable-diffusion-xl-base-1.0", {...input, stream: true})) as ReadableStream<any>;

const response = (await ai.run("@cf/stabilityai/stable-diffusion-xl-base-1.0", {...input, stream: true})) as ReadableStream<any>;

any plans to launch a TTS model as well? like Coqui?

Hello! I was wonder if some features were on the roadmap, and if not, I'd like to request them! I think that enforcing JSON output like Ollama and Llama.cpp do would be a great feature for devs who want to get structured data output consistently for parsing. Ollama lets you use format: "json"format: "json" in your request and it handles applying the grammar for you. See here for an example: https://github.com/ollama/ollama/blob/main/docs/api.md#generate-a-completion

Another features I'd like to see is the option to return token counts along with the response. Its hard to judge what my users are using with no token counts, and I don't really want to have to add a step in order to calculate them.

Is the strengthstrengthparameter for @cf/runwayml/stable-diffusion-v1-5-img2img@cf/runwayml/stable-diffusion-v1-5-img2img clamped and/or quantized in some weird way? Strength 0.095 generates an output that's close to identical to the source (albeit degraded), while 0.095001 generates a noisy version of the source. Strength 0.0 seems to produce as wildly different output as if it was set to 1.0. (Values outside the range 0.0 to 1.0 throws InferenceUpstreamError.)

Raylight•3/21/24, 11:37 AM

While I'm at it, looks like @cf/runwayml/stable-diffusion-v1-5-inpainting@cf/runwayml/stable-diffusion-v1-5-inpainting throws InferenceUpstreamError on strength values below 0.05 (except 0). Haven't tested this on version 1.1.0, though.

acusti•3/22/24, 2:53 AM

@chand1012 i had this exact need (the format: 'json'format: 'json' option), and i couldn’t find a satisfactory solution out there, so i made a parseAsJSONparseAsJSON util that takes a string and parses it as JSON even if it has syntax errors or too many closing curly braces, or not enough curly braces, or overly escaped characters, or unescaped characters, or pre- and post-ambles, or…

it’s a JS (typescript) package available on NPM called @acusti/parsing@acusti/parsing. here’s the readme: https://github.com/acusti/uikit/tree/main/packages/parsing

i also implemented some simple few-shot prompting modelled on what’s documented in this guide to get the LLM to return JSON: https://www.pinecone.io/learn/llama-2/#Llama-2-Chat-Prompt-Structure

Hi all, I am trying to use cloudflare AI locally, running

wrangler dev

wrangler dev

, and I get the following error when I try using the '@cf/facebook/bart-large-cnn''@cf/facebook/bart-large-cnn' model:

Uncaught (async) Error: InferenceUpstreamError: {"success":false,"errors":[{"code":10000,"message":"Authentication error"}]}

Uncaught (async) Error: InferenceUpstreamError: {"success":false,"errors":[{"code":10000,"message":"Authentication error"}]}

If I run wrangler dev --remotewrangler dev --remote, it does work, but I cannot use remote mode as I also use Cloudflare Queues in my app together with workers AI, and queues do not work in remote mode.

Any ideas what might be wrong? I am using "wrangler": "^3.36.0""wrangler": "^3.36.0" and "@cloudflare/ai": "^1.1.0""@cloudflare/ai": "^1.1.0"

@TheMightyPenguin whenever i see Authentication errorAuthentication error i run wrangler loginwrangler login. it surprises me how often i have to re-authenticate when doing local dev (once every few days). i’ve speculated that it might have to do with how often i’m connecting to a different wifi network and changing my IP address, but that might be totally wrong. regardless, re-authing has always resolved it for me.

Some feedback regarding @cf/runwayml/stable-diffusion-v1-5-inpainting@cf/runwayml/stable-diffusion-v1-5-inpainting (and @cf/runwayml/stable-diffusion-v1-5-img2img@cf/runwayml/stable-diffusion-v1-5-img2img):
The models seem to produce an output with a noticeable shift in color balance. Repeated inpainting will quickly shift the image towards purple. See the attached images below. The first image is the result of doing 10 passes (i.e. using the result as source) of inpainting with an empty (black) mask. The second is the same process but with an added "hack" (i.e. more of a band-aid than a solution) that does histogram matching after each pass. The third image is a typical result from a single pass of inpainting merged with unmasked pixels from the source. (Shown with mask overlayed on source.)

This seems to be a well-known problem that (possibly) can be traced back to the VAE, and (possibly) be solved by using an updated version of the VAE. Whether that's the case here is another question.

Raylight•3/25/24, 5:49 PM

(The black to the left is simply because the "safety checker" believes the image is harmful content without it.)

Mmichelle this is so interesting, is it a model problem though or specific to workers ai?

Raylight•3/25/24, 10:38 PM

I believe it's a problem with the model, so maybe it belongs to the catch all "cloudflare-ai". The result should be the same if using the API. Although using workers ai + client side javascript will involve more head-scratching and second-guessing your code.

I found this https://github.com/AUTOMATIC1111/stable-diffusion-webui/issues/410 which seems to match my own testing.
