Model tries to call unknown function multi_tool_use.parallel

API Bugs

Hi, testing out an assistant in a playground it tried to call a function called “multi_tool_use.parallel” like:

      "required_action": {
        "type": "submit_tool_outputs",
        "submit_tool_outputs": {
          "tool_calls": [
            {
              "id": "call_0obfNi7th7uJiMp6pHUkkh8Z",
              "type": "function",
              "function": {
                "name": "multi_tool_use.parallel",
                "arguments": "{\n  \"tool_uses\": [...]\n}"
              }
            }
          ]
        }

This seems like it contradicts the documentation that multiple parallel tools should be called as a array of [tool_calls], and I can’t find any documentation on this function. This seems unexpected behavior at least!

Could be an internal tool module setup by OpenAI team @kraemahz

3

perhaps an issue with the library? tried upgrading to the latest version?

4

The call happened while using the playground with an assistant, so this is all on OAI’s side.

5

hey, @kraemahz did you sendup finding what could be causing that ? I want to run multiple function but it seems that I get the multi_tool_use.parallel error

6

@kraemahz got the same output, looks like occuring when the models function calling thinks he needs to run multiple tools, probably something internal yep

How did you solve this problem? I got this function too. But I just decal one method in function call.

Just debugging a code here and this appeared:

Hitting this too. Is this by-design and should be supported by host applications?

I ran into the same today though in my case the function is named parallel without the leading multi_tool_use. No resolution at the moment.

13

I keep getting the same - it must be a training issue mustn’t it? I’ve been changing the instructions a lot and still getting this issue

I’ve also been facing this issue every now and then - in my experience the calls would follow a predictable structure that could be reliably hotfixed. I’m guessing OpenAI will fix this eventually, but in the meantime I built a quick patch for this that’s easy to drop into a project to make the problem go away:

github[dot]com/phdowling/openai_multi_tool_use_parallel_patch

Usage is as follows:
pip install openai_multi_tool_use_parallel_patch

In your code:

import openai_multi_tool_use_parallel_patch  # import applies the patch
import openai

client = openai.AsyncOpenAI(...)  # sync client will be patched too

...

response = await client.chat.completions.create(...)  # no changes to the call signature or response vs vanilla OpenAI client

FYI: Patch uses removeprefix(), added in Python 3.9, but PyPi metadata says it’s compatible w/ 3.8.

AttributeError
'str' object has no attribute 'removeprefix'

Yea all good thanks, just updated the openai package to it’s most recent version and implemented as the doc suggested works fine.

@atwoodjw_agh Yeah my bad. It also turns out I published the patch with a typo and it would not have worked anyway - it’s fixed now and I just re-released to PyPI. I also tested with python 3.7, things should work okay now. Unfortunately I cannot actually reproduce with a real OpenAI API call at the moment, but if these glitchy responses still gets generated in the same format, the patch should work.
