from the docs it says any future reqs will error if I reach that neuron quota :P

All limits reset daily at 00:00 UTC. If you exceed any one of the above limits, further operations will fail with an error.

Hey, how can I have message history such that ai model will have a message history and depend on this history will answer. for example.

User: sum of 2 + 2? -> Model: the answer is 4 -> User:now multiply the result by 2

User: sum of 2 + 2? -> Model: the answer is 4 -> User:now multiply the result by 2

User: sum of 2 + 2? -> Model: the answer is 4 -> User:now multiply the result by 2

User: sum of 2 + 2? -> Model: the answer is 4 -> User:now multiply the result by 2 at last user user input, ai model should have a history of messages and know what the

result

That is possible but Workers AI will not do that for you. You need to store the messages somewhere (or have the client re-send the full history) and then send the full conversation with each Workers AI request.

That is just how LLMs work and how every provider does it, not just Workers AI. OpenAI, Gemini, Claude, etc all need to see the past history in order to act on it. If a message isn't in the context then it will not be seen by the model.

/completions

/completions

/completions,

/chat/completions

/chat/completions

/chat/completions) for new models (Eg: gpt-oss-20b)?

@sodepr The Cloudflare blog said in August that completions support was "coming soon" to the gpt-oss models. I haven't seen any update from them since, though. It would certainly be nice to have because, as you've pointed out, not everything supports the responses endpoint yet.

Hello! I Been looking at worker ai For txt2img. Im quite new with these different Image models, i Have usually just used Gemini or chatgpt Image generation. But to cut down on spending im intrested of using worker ai to generate images. So My question which of The avaivable Image models IS best to create Hand draw pictures? I dont need realism. I tried Flux schell from huggingface but that tend to not create images that Look like drawings.

The endpoint recieves the url and downloads during the endpoint runtime, and then transcribe the audio to text and then vectorize it.. I mean it takes a lot of time cpu compute so is it possible in workers?

You could try lucid-origin? It generates some nice images in my experience. e.g. here's a short example:

lucidOrigin.get('/', async (c) => {
    // Generate the image
    const response = await c.env.AI.run(
        "@cf/leonardo/lucid-origin",
        {
            prompt: "picture in a hand-drawn style of a mini goldendoodle dog playing fetch in a field"
        }
    );
    console.log(response);

    // Embed the image directly as a data URL
    const imageDataUrl = `data:image/jpeg;base64,${response.image}`;

samjs•10/12/25, 6:07 PM

Hey @Sudhan . There are a couple of things that might help here:

1. you can pass in a stream of bytes for the inputs in many of the models, e.g. in the nova-3 example you can fetch and pass in the body directly (without needing to await it: https://developers.cloudflare.com/workers-ai/models/nova-3/)
2. Some models (like nova-3) support our async batch API (https://developers.cloudflare.com/workers-ai/features/batch-api/). So you can submit the job for running the inference and then poll for the response.

In both cases, it shouldn't be using much compute in the worker itself.
