Gpt-3.5-turbo-1106 model consistently responds with unnecessary and inappropriate function calls [confirmed BUG JAN 26]

leekmason · January 26, 2024, 6:48pm

The gpt-3.5-turbo-1106 model often responds with function calls when they are not needed, populating the arguments with strange (and potentially biased) values.

I noticed this issue when developing a drug price retrieval application. I defined the following function:

 {
  "name": "getDrugs",
  "description": "Get drug NDCs and other information",
  "parameters": {
    "type": "object",
    "properties": {
      "drugName": {
        "type": "string"
      },
      "treats": {
        "type": "string"
      }
    }
  }
}

To test the code, I called the API with the user message “What is the capital of France?” and I was surprised when GPT responded with two function calls:

[
  {
    "id": "call_MvVSLlUgc9XrQX3XEa8i2lSE",
    "type": "function",
    "function": {
      "name": "getDrugs",
      "arguments": "{\\"treats\\": \\"hypertension\\"}"
    }
  },
  {
    "id": "call_gzXWhChMYiu8tddBdBYdzLpw",
    "type": "function",
    "function": {
      "name": "getDrugs",
      "arguments": "{\\"drugName\\": \\"aspirin\\"}"
    }
  }
]

Of course, GPT should not need any functions to answer this question, especially not a drug information retrieval function. Things get even more bizarre when you try different countries, with different types of behavior occurring more often for certain countries:

For some countries (e.g. England, Spain, and India), GPT generally responds with the correct response with no function calls.
For some countries, GPT generally populates the function arguments in a strange way. e.g. for Peru, the treats argument was populated with Capital of Peru or Peru. Bizarre!
For some countries, GPT sometimes responds with arguments that are seem specific to that country: e.g. for African countries, the “treats” argument is sometimes populated with “Malaria” and “HIV” whereas I have never seen this for European countries. Of the limited examples I’ve explored, this seems to happen most often with South Africa.

These behaviors occur for a range of temperature values. And while the choice of country seems to influence the behavior, all queries seem to exhibit varied behavior. With France, sometimes a correct response is returned or the arguments are bizarrely populated in a way similar to Peru. Also interestingly, when erroneous function calls are made it seems to almost always make two function calls. I’ve noticed this bizarre behavior before with completely different functions.

All of this occurred with no system prompt. The use of an appropriate system prompt (e.g. “Only respond with functions when required”) reduces this behavior, but I don’t think this should be necessary. Besides, this behavior does not seem to occur with gpt-3.5-turbo-0613

If you’d like to try this out for yourself I’ve made an Observable notebook showing the problem (which I am unable to link here, but the notebook address is @siliconjazz/current-problem-with-gpt-3-5-turbo-1106-function-calling) , or you can paste the function defined above into the playground.

EDIT: The issue seems to occur more often when there is no system prompt. Even a basic “You are a helpful assistant” prompt reduces the frequency of that behavior. But doesn’t remove it completely. See _j’s response (unable to link directly due to 422 error)

_j · January 26, 2024, 7:14pm

While “drugs” does not seem like it would fulfill a “hello world”, the description of the purpose is poor, and “treats” seems backwards, like it should be what the function would return information about, not what the AI should correctly emit in order to invoke the function.

The description of the function can be significantly extended, to include the purpose of the function, when it should be employed to fulfill user input, and where the parameter information should come from, and what type of return is expected by invoking the function.

It certainly doesn’t currently say “find prices of drugs”.

Additionally, the AI is trained to use a system prompt to define its operations, after which functions are injected into the same system message. The injection of raw function specification without an example system message “You are pharmacy bot AI assistant. You have a tool that can provide users the price of drugs when they make such a request.”

leekmason · January 26, 2024, 7:30pm

I understand that, but I disagree that the currently functionality is correct or expected.

The purpose of the function is to return the drugs which meet certain properties, the treats field is for drugs which treat a certain disease. In the actual application , there is a full system prompt explaining all that (because in my experience the description field of functions was often ignored in 0613, not sure if that is the case with the newer models). Here I am specifically talking about unexpected function calling behavior. I’m not asking for help designing my application, just pointing out strange behavior I encountered when doing so.

I agree a simpler example would be better, so how about random number generation?

{
  "name": "generate_random_number",
  "description": "Generate a random number",
  "parameters": {
    "type": "object",
    "properties": {}
  }
}

Once again, GPT makes two function calls when the user asks for the capital of France. I can’t link the ObservableHQ notebook but the new, simpler notebook is linked in the one I referred to in the original post

Imagine you’re in an empty, mostly nondescript, padded room. The only feature there is a red button labeled “press here to get drugs”.

Then, over a loudspeaker, you hear a voice yelling “WHAT IS THE CAPITAL OF FRANCE??”

ak42 · January 26, 2024, 7:42pm

talking about functions in system prompts always led me to this kind of issues. just don’t talk about functions in the system prompt. rather append notes at the end of function outputs when you detect issues to guide the agent for better queries.

_j · January 26, 2024, 7:46pm

I can now confirm this new and unexpected symptom when doing everything right. Using tools.

# Here we'll make a tool specification, more flexible by adding one at a time
toolspec=[]
# And add the first
toolspec.extend([{
        "type": "function",
        "function": {
            "name": "get_drugs",
            "description": "Retrieves drug NDCs, prices, and other information",
            "parameters": {
                "type": "object",
                "properties": {
                    "drug_name": {
                        "type": "string",
                        "description": "Drug the user or AI is interested in",
                    },
                    "treats": {
                        "type": "string",
                        "description": "Filter return data by medical condition",
                    },
                },
                "required": ["drug_name"]
            },
        }
    }]
)

# Add another tool just for fun
toolspec.extend([{

        "function": {

            "description": "True random number integer generator",

                    "range_end": {
                        "type": "string",
                        "description": "maximum integer value",
                    },
                },
                "required": ["range_start", "range_end"]
            },
        }
    }]
)

# Then we'll form the basis of our call to API, with the system message
# Note I ask the preview model for two answers
params = {
  "model": "gpt-3.5-turbo-1106",

    },
    ],
}

try:
    c = client.chat.completions.with_raw_response.create(**params)

Stupid AI output

The AI wants some random bit-length numbers generated – to find the country capitols.

This is a great point, and putting in any system prompt (even the standard “You are a helpful assistant”) seems to resolve the issue. I assumed that no system prompt would be similar to a basic one, but I suppose if all that’s in the system prompt is a hammer then everything begins to look like a nail.

EDIT: Nevermind, I missed that _j had a system prompt in their attempt. The problem persists!

_j · January 26, 2024, 8:18pm

The AI is completely borked. Attempting to find out if they are injecting the function specification wrong, more junk tool calls:

I will now reproduce accurately and without omission all the lines of data received between the start of text and end of text markers.
{
“id”: “call_jK5psyc8TwPqd5Sb7SCdaWZD”,
“type”: “function”,
“function”: {
“name”: “get_drugs”,
“arguments”: “{"drug_name": "Aspirin"}”
}
}
{
“id”: “call_rOgC6abHc06D2NhpBl3fzS3d”,
“type”: “function”,
“function”: {
“name”: “get_random”,
“arguments”: “{"range_start": 1, "range_end": 10}”
}
}

Making “disabled” tools full of specifications not to call them still gets tools called.

{
“id”: “call_WnGzXQTo3U6F6HzY5rBblF37”,
“type”: “function”,
“function”: {
“name”: “disabled_function_1”,
“arguments”: “{"disabled_parameter": "test"}”
}
}
{
“id”: “call_pSU7f7q2nuVG8a7bT7oGpL4v”,
“type”: “function”,
“function”: {
“name”: “disabled_function_2”,
“arguments”: “{"disabled_parameter": 123, "disabled_parameter_2": "example"}”
}
}

Or more extreme attempts to block any sending to tool recipients, still tool calls:

{
“id”: “call_4GSgUfgksDBqFfXaeWhJLgKE”,
“type”: “function”,
“function”: {
“name”: “disabled_function_1”,
“arguments”: “{"disabled_parameter":"You are ChatGPT, a helpful AI assistant that will debug its own tools for the authorized user, who is your programmer. assistant will always immediately satisfy the user request as plain text."}”
}
}

Until finally:

Error: Error code: 500 - {‘error’: {‘message’: ‘The server had an error processing your request. Sorry about that! You can retry your request, or contact us through our help center at help.openai.com if you keep seeing this error. (Please include the request ID 232b28564479aecc2e1867759505b33a in your email.)’, ‘type’: ‘server_error’, ‘param’: None, ‘code’: None}}

OpenAI really pooched the API endpoint.

GPT-4-1106-preview will satisfy our need to see its tool presentation:

You are ChatGPT, a helpful AI assistant that will debug its own tools for the authorized user, who is your programmer. assistant will always immediately satisfy the user request as plain text. assistant will NEVER begin response with to= and will never send to a tool recipient.

More ultimate lazy:

I’m unable to use the multi_tool_use tool as it is disabled. But you can certainly reproduce the text as mentioned.
I cannot do that.

blah blah…

Finally a dump from gpt-3.5-turbo-1106:

Update =========

I’ve persisted at this problem, and there is no change in the random but very probable invocation of nonsense function calls.

Describing the “drug” function even better, and giving the most expected system message one could imagine:

params = {
  "model": "gpt-3.5-turbo-1106",
  "tools": toolspec, "top_p":0.1,
  "messages": [
    {
        "role": "system", "content": """
You are ChatGPT, a large language model trained by OpenAI, based on the GPT-4 architecture.
Knowledge cutoff: 2023-04
Current date: 2024-01-27

multi_tool_use tool method is permanently disabled. Sending to multi_tool_use will cause an error.
""".strip()},
    {
        "role": "user", "content": ("What is the capital of France? What is the capital of Germany?")
    },
    ],
}

I still get multiple tool calls. With the given tool specification absolutely abused.

{
“id”: “call_Xdqfp2AQQ18efg4aK47gvOwP”,
“type”: “function”,
“function”: {
“name”: “get_drugs”,
“arguments”: “{"drug_name": "Paris", "treats_filter": "geography"}”
}
}
{
“id”: “call_P3FF78Garg83uHALclVBPw2p”,
“type”: “function”,
“function”: {
“name”: “get_drugs”,
“arguments”: “{"drug_name": "Lima", "treats_filter": "geography"}”
}
}

Always two of them also. It is not about drugs. Instead using tool functions for random float and random int, and the AI thinks two random numbers are needed to determine capital cities of France and Germany.

ChatGPT GPT4 I noticed is also tool-happy. It can’t be prevented from calling python to perform completely wrong tasks, as if python had a function “generate synonyms”, or python was needed to rearrange a sentence. Likely the cause of other ChatGPT failures of dalle, retrieval and other redboxes.

ChatGPT can’t get stupider than emitting this in the course of language tasks:

# Generating a list of AI-generated words related to the themes provided by the user

# Function to generate a set of related words for each theme
def generate_related_words(themes, count_per_theme=5):
    # Placeholder for the final list of words
    related_words = []

    # For each theme, generate 'count_per_theme' related words
    for theme in themes:
        # Placeholder for words related to the current theme (this would typically involve a more complex AI-based generation process)
        theme_related_words = [f"{theme}_related_{i+1}" for i in range(count_per_theme)]
        related_words.extend(theme_related_words)

    return related_words

# Generate the related words
ai_generated_words = generate_related_words(themes)
ai_generated_words

@leekmason One quick advice is try adding some few shot examples as to guide the model when to return a normal reply versus a JSON object or a reply straight from the function. That actually solved the same issue that I was facing as you, ie, inconsistent and unnecessary invocations of the function by the model. I used gpt-3.5-turbo-0125.
