Have also seen this since I tried using it yesterday - pdf and csv and xls all converted fine. Just the images error for me. Am using current 4.17.0 of wrangler. Am running local dev.

Out of curiosity, what do folks who use the Cloudflare Worker AI stuff feel about its pricing model? I did some comparisons since we have Azure OpenAI and Cloudflare available at work, and unlike other CF offerings (eg: Cloudflare Workers themselves), it looked surprisingly expensive. The mid range llama models are priced about the same as Azure OpenAI Nano/Mini per million token, give or take (its not an apple to apple comparison), while I expected them to be much cheaper. The 10k neurons a day not withstanding (which, to be fair, does make a decent difference)

Is there something I'm overlooking? I'm just comparing input/output tokens here, so its a pretty naive comparisons, since again its tough to compare "equivalent" models between Llama models and the GPTs.

zensin•6/1/25, 7:40 AM

I'm only using them for dev testing because of price and the models being offered are old/outdated. For me to consider using it, I would need up to date models and pricing similar to openrouter.

Z

zensin•6/1/25, 7:48 AM

I expect there to maybe be a slight premium for being close to all the users and not having cold-start issues but the cases where that makes a big difference are few

Hello, is there any roadmap for custom model support ? Like on the fly model download from hugging face ?

G

gabrielstuff•6/5/25, 6:19 PM

The only useful info I’ve come across so far is from here:
https://community.cloudflare.com/t/newer-ai-models-bring-your-own-model/597274
https://github.com/cloudflare/cloudflare-docs/issues/11039
https://developers.cloudflare.com/changelog/

At the moment, “bring your own model” is something very few platforms do well. Among the better ones, I’d say Scaleway Managed Inference and Deepinfra are leading the pack.

Being able to plug in your own model, especially for tasks like completion or classification, is a huge deal. It opens the door to running smaller, highly optimized models, including those trained for other languages or specific domains. And for fine-tuned models, this could really set Cloudflare apart if done right !

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/

At the moment Flux Kontext is not an open-weight model, so I expect they wouldn't add it until if/when it becomes open-weight the same as Flux is.

I believe BFL has announced that they plan to make it open-weight (or, well, a lighter version of it the same as they've done with Flux Dev/Schnell vs Pro) but haven't actually done that yet.

Has LORAs support been updated for the models in this announcement? https://blog.cloudflare.com/workers-ai-improvements/

The docs are a bit confusing on this: Llama 3.1 and Mistral Small 3.1 are listed as supported, but the model finder and API docs don't reflect LORA support, and the blog post lists them as soon
