Hey James, I believe you're from the cloudflare team.

I wanted to know why are no claude models in cloudflare-ai ? It would help me so much by not depending on any external services than cloudflare for the whole platform (my app).

Do you think I can bring this up in the office hours today ? I never attended those but I feel there's a huge need for the current leading models in the models we have, it would help in many ways.

Thanks.

JamesOP•8/27/25, 1:09 PM

I'm not on the Cloudflare team, just a community champ/mvp

I'm not sure there's any office hours today, especially not with the WAI team, but I know the want for more flagship code models has been talked about a lot recently with the current selection being a little lacklustre.

J

JamesOP•8/27/25, 1:10 PM

The claude models aren't freely available, which is why I imagine we've not seen them on WAI. But even something like Kimi would be a huge step up over the current selection, I entirely agree.

Mirza•8/27/25, 1:11 PM

Ohh i mistaken the cloudflare community champ tag on you as a team member.

I'm having startup credits from cloudflare and with that I've got weekly office hours access where founders come and maybe discuss about what can help them to do better etc....

Mirza•8/27/25, 1:12 PM

Yeah there are only the open source models in the list, maybe a partnership with claude would help us as builders.

Hey @Fabian . Streaming for the gpt-oss models is not currently supported, but we're working on it and hope to have an update soon!

samjs•8/27/25, 4:48 PM

Hey folks! Happy AI Week. I'm on the Workers AI team and will be around to help answer any questions you all have

HHimanshu Is there an ETA for function calling support for gpt oss models in workers ai?

S

samjs•8/27/25, 4:52 PM

Hey @Himanshu ! Function calling should work with the gpt-oss models. Here's an example of that with our sandbox SDK: https://github.com/cloudflare/sandbox-sdk/blob/main/examples/code-interpreter/src/index.ts#L73-L91

We've also tested against the compatibilty suite here: https://github.com/openai/gpt-oss/tree/main/compatibility-test and are getting ~93% successes. Do you have an example of what you were trying that didn't work?

We're also actively working on integrating support for the builtin

code_interpreter

code_interpreter

tool to make some of this even easier.

samjs•8/27/25, 4:56 PM

Hi @Mirza

currently we've mostly been running open source models on our platform. Though as of today we have new partner models we're supporting as James linked above.

Definitely feel free to share your feedback in your office hours today. Sharing here is also a good way for us to know what is important to folks. Are you open to sharing more about your use case? I'd also love to hear if you've tried the gpt-oss models for your use case and how those compare.

Himanshu•8/27/25, 5:05 PM

Amazing! I was trying it out with ai sdk, but the normal tool call invocation that worked with other function calling models like Llama 3.3, didn't work. I checked the docs, and there was no mention of tool call support for these models, so I took a back seat. I'll retry and update you. Thanks again.

Himanshu•8/27/25, 5:44 PM

Leonardo lucid-origin is a fantastic model!!

Prompt: Ultra-realistic 3D render of Times Square at night with neon lights and bustling atmosphere. A massive digital billboard dominates the scene, displaying the Cloudflare logo with the words ‘Workers AI’ in bold white font on a vibrant orange background. The billboard is crisp, glowing brightly against the dark sky, reflecting on nearby glass buildings. Camera shot captured from across the street at a slightly low angle, showing street lights, cars, and people walking, adding scale and realism. Photorealistic textures, cinematic lighting, and a dramatic depth-of-field emphasize the billboard as the centerpiece.

I think we're still working on the documentation! But in short it should look something like:

export default {
  async fetch(request, env, ctx): Promise<Response> {
    const resp = await env.AI.run("@cf/deepgram/aura-1", {}, {
      websocket: true
    });
    return resp;
  },
} satisfies ExportedHandler<Env>;

    return resp;
  },
} satisfies ExportedHandler<Env>;

thanks this is helpful for bindings. What is the equivalent way of using websockets over the CF REST api? https://developers.cloudflare.com/api/resources/ai/methods/run/

J

John Spurlock•8/29/25, 4:27 PM

how does the cf partnership thing work with deepgram in terms of the "model improvement plan" - does setting

mip_opt_out=true

mip_opt_out=true

affect the unit pricing stated on the cf api page? (when using deepgram directly that significantly increases the price)

Ana•8/31/25, 4:45 PM

Hello. I’m experimenting with Traditional function calling and it seems to only work with one of the 4 models that should support it:

@hf/nousresearch/hermes-2-pro-mistral-7b

@hf/nousresearch/hermes-2-pro-mistral-7b

For the other models I get the response:

 {
  "errors": [
    {
      "message": "AiError: AiError: Invalid input",
      "code": 8001
    }
  ],
  "success": false,
  "result": {},
  "messages": []
}

 {
  "errors": [
    {
      "message": "AiError: AiError: Invalid input",
      "code": 8001

  "success": false,
  "result": {},
  "messages": []
}

 {
  "errors": [
    {
      "message": "AiError: AiError: Invalid input",
      "code": 8001
    }
  ],
  "success": false,
  "result": {},
  "messages": []
}

 {
  "errors": [
    {
      "message": "AiError: AiError: Invalid input",
      "code": 8001
    }
  ],
  "success": false,
  "result": {},
  "messages": []
}

To stop receiving this message I need to give a type: “function” to my tools and wrap them in a function:

tools: [
    {
      type: “function”,
      function: { 
        name: "getWeather",
        description: "Return the weather for a latitude and longitude",
        parameters: {
          // ....
        },
      },
    }],

tools: [
    {
      type: “function”,
      function: { 
        name: "getWeather",
        description: "Return the weather for a latitude and longitude",
        parameters: {
          // ....
        },
      },
    }],

tools: [
    {
      type: “function”,
      function: { 
        name: "getWeather",
        description: "Return the weather for a latitude and longitude",
        parameters: {
          // ....
        },
      },
    }],

tools: [
    {
      type: “function”,
      function: { 
        name: "getWeather",
        description: "Return the weather for a latitude and longitude",
        parameters: {
          // ....
        },
      },
    }],

But this way none of the other 3 models (

@cf/meta/llama-3.3-70b-instruct-fp8-fast

@cf/meta/llama-3.3-70b-instruct-fp8-fast

,

@cf/mistralai/mistral-small-3.1-24b-instruct

@cf/mistralai/mistral-small-3.1-24b-instruct

,

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

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

can use function calling at all (the reply is always text).

Anyone else with the same issue?
