excited to try out the ERNIE 4.5 family of models that were open-sourced today: https://ernie.baidu.com/blog/posts/ernie4.5/

ERNIE Blog

Announcing the Open Source Release of the ERNIE 4.5 Model Family

We introduce ERNIE 4.5, a new family of large-scale multimodal models comprising 10 distinct variants. The model family consist of Mixture-of-Experts (MoE) models with 47B and 3B active parameters, with the largest model having 424B total parameters, as well as a 0.3B dense model.

When using

@cf/meta/llama-3.1-8b-instruct-fp8-fast

@cf/meta/llama-3.1-8b-instruct-fp8-fast

or

@cf/meta/llama-3.2-3b-instruct

@cf/meta/llama-3.2-3b-instruct

I'm getting the following error:

message: "AiError: 5025: This model doesn't suuport JSON Schema."

message: "AiError: 5025: This model doesn't suuport JSON Schema."

JSON_Schema is shown in the CF's API docs for both models. So what's the issue, are the docs wrong? Seems to be possible, there is a typo in the error message

. If the docs are wrong how can I determine which model support JSON Schema? Otherwise, what could be the problem?

B

blindChicken•7/4/25, 12:03 AM

Okay! Found the fix, type must

json_object

json_object

and not

json_schema

json_schema

like so:

response_format: {
  type: 'json_object',
  json_schema: responseSchema
}

response_format: {
  type: 'json_object',
  json_schema: responseSchema
}

So error in the docs?

B

blindChicken•7/4/25, 12:10 AM

While I'm ranting about the docs, it would be nice if the json format of the API Schema would be collapsible, as it is very long and hard to follow indentation down the page. I copy it to VS-code when I need it, but it would be great if would be included on the page as UI element.

Hello everyone, does anyone here already called LLAMA4 (

@cf/meta/llama-4-scout-17b-16e-instruct

@cf/meta/llama-4-scout-17b-16e-instruct

) with some tools/ function calling. With or without the compatibility mode (https://developers.cloudflare.com/workers-ai/configuration/open-ai-compatibility/) i got answer with no tool results, and no Ai message either. I am using an official Java Client library... would like to know if i need to keep pushing (tried with strict tools) and is it expected ?

Cloudflare Docs

OpenAI compatible API endpoints

Workers AI supports OpenAI compatible endpoints for text generation (/v1/chat/completions) and text embedding models (/v1/embeddings). This allows you to use the same code as you would for your OpenAI commands, but swap in Workers AI easily.

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•7/7/25, 3:42 PM

The docs are generated wrong. I reported and docs team said it was out of their hands. You can see the list of supported models at the bottom of this page however: https://developers.cloudflare.com/workers-ai/features/json-mode/

Interesting that you could coax a json object with

json_object

json_object

however! I'll have to check that out

Cloudflare Docs

JSON Mode

When we want text-generation AI models to interact with databases, services, and external systems programmatically, typically when using tool calling or building AI agents, we must have structured response formats rather than natural language.

Ꭱ

ᎡᴜᴛʜʟᴇssŦᴀᴄᴛɪᴏɴ•7/7/25, 4:20 PM

On a unrealted note:

Anyone have insight as to why I consistently am getting the same output for text-generation for the same prompt? I explicitly have tried setting

{ temperature: 5, top_p: 1, seed: Math.floor(Math.random() * 9999999999) + 1 }

{ temperature: 5, top_p: 1, seed: Math.floor(Math.random() * 9999999999) + 1 }

to attempt to encourage different results every run... but no luck

Chaika•7/14/25, 4:23 PM

Just saying in case it's worth noting: Green/champs are just volunteers and the AI team has said things in the past about needing to scale models, espec after launches/big increases: workers-ai, which is where I'm saying that from, but they did not comment on this exact issue/rise in errors (nor was there a status page). I track those capacity errors on my own (unrelated to the team) and I do see them come and go for various models, and it does seem to be around just scaling and such

Feature Request: Add MedGemma Models to Cloudflare Workers AI
Dear Cloudflare Workers AI Team,
I would like to request the addition of MedGemma models to the Workers AI platform. MedGemma is Google's specialized collection of medical AI models that would significantly enhance the platform's capabilities for healthcare applications.
Key Benefits:

Compact Size: MedGemma models are relatively small, making them well-suited for edge deployment
Medical Specialization: These models are specifically trained for medical use cases, filling a current gap in Workers AI's model offerings
Healthcare Applications: Would enable developers to build medical applications directly on Cloudflare's edge infrastructure
Cost-Effective: Smaller model sizes mean lower computational costs while maintaining medical domain expertise

Use Cases:

Medical chatbots and virtual assistants
Clinical decision support tools
Medical document analysis
Healthcare workflow automation

Reference:
MedGemma models are available in Google's model collection and have been designed with medical applications in mind.
Adding MedGemma would position Cloudflare Workers AI as a leading platform for healthcare AI applications, combining the benefits of edge computing with specialized medical AI capabilities.
Thank you for considering this request. I believe this addition would greatly benefit the developer community working on healthcare solutions.
Best regards, Vladimir

Hey guys! I'm trying to use workers AI with the openai compatible endpoint. While it's been great for text generation, I wanted to plug it into n8n as the model for the AI agent, since the endpoint is openai compatible, and the model I'm using (

@cf/meta/llama-4-scout-17b-16e-instruct

@cf/meta/llama-4-scout-17b-16e-instruct

) does support tool calls as per this page.

The problem is that it's not working in agents that have tools to call. Upon looking further into the problem, there was a thread in n8n's GitHub issues

#15862

#15862

#15862

#15862 that explored this exact issue. Apparently, the tool call input format in the response from the cf model was wrong, and hence langchain would pick it up as a normal response (more details in the github thread).

Would really appreciate some response on this. Thanks.
