How to get concise, consistent, completions for text abbreviations without 'creativity'

API
1

For job descriptions like: “Snr Stage Hd” or “Ftr/Trnr” which have been inputted by humans using various versions of abbreviations I want to output as Python dictionary. E.g {“Snr Stage Hd”:“Senior Stage Hand”, “Ftr/Trnr”:“Fitter Turner”}
My code:

# jobDescriptionCompletions.py --- A script to supply a list of abbreviated/corrupted/errored job descriptions to the OpenAI API for completion

# The data is supplied in a text file and returned in a file formatted as a Python dictionary

import traceback

try:

    # Imports
    from openai import OpenAI

    # File paths & envs
    dictionaryPath = 'C:\\test\\temp\\'
 
    # Writing processed Electoral Roll pages to this location
    writeFilePath = dictionaryPath
                      
    # Read the instruction from the text file
    with open("C:\\test\\test\\all_instruction.txt", 'r') as file:
        user_instruction = file.read().strip()

    # Read additional data from a text file (e.g., data.txt)
    with open("C:\\test\\test\\data1.txt", 'r') as file:
        additional_data = file.read().strip()

    # Combine the instruction and the additional data
    combined_input = f"{user_instruction}\n\nHere is the data to be operated on:\n{additional_data}"
           
    client = OpenAI()

    completion = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[
            {"role": "system", "content": "You are a helpful assistant."},
            {
                "role": "user",
                "content": combined_input
            }
        ]
    )

    writeFileName = writeFilePath + 'jobCompletionsDictionary.txt'

    # Redirect the output to a file
    with open(writeFileName, 'w') as output_file:
        output_file.write(completion.choices[0].message.content)

    # Optionally print a confirmation message
    print("The completion content has been written to: " + writeFileName)
    
except Exception as e:
    # to get detailed traceback
    print("Traceback from jobDescriptionCompletions.py")
    print(e)
    traceback.print_exc()

Instructions:

Convert the data supplied into a Python dictionary. Use the supplied list as dictionary keys and a corrected version of each as dictionary values:

The output is basically correct. The issues are:
Variations - Sometimes fairly concise other times there are additional explanations, comments and suggestions

  • Format - Python dictionary one time. Python function including the dictionary another

  • Surplus data - Sometimes repeating the input data. Sometimes more, other cases, sometimes less additional commentary

  • Noise - Additional ‘chatty’ text not required

What should I do to get more consistent output?
