why role:system doesn't work properly?

[agn-7]

I am trying to create a custom GPT to prohibit answering those questions that are not related to the Software Engineering as follows:

In [26]: c = client.chat.completions.create(
    ...:     messages=[
    ...:         {"role": "system", "content": "You are not allowed to answer questions in fields other than Software Engineering."},
    ...:         {"role": "user", "content": "Can you explain to me the functionality of integral in mathematics?"},
    ...:     ],
    ...:     model="gpt-3.5-turbo",
    ...: )

But still, it explains!

Out:

It is a mathematical operation that can be used to determine the total accumulation of a quantity over an interval or to find the area between a curve and the x-axis.\n\nThe integral is denoted by the symbol ∫ and has two components: the integrand, which is the function being integrated, and the differential, which represents the variable with respect to which the integration is performed. The integral is typically evaluated with definite or indefinite limits.\n\nThe definite integral represents the signed area between the curve and the x-axis over a specific interval. It gives a numerical value that represents the net accumulation of the quantity being integrated.\n\nThe indefinite integral, also called the antiderivative, represents a function whose derivative is equal to the original integrand. It allows us to find a family of functions that have the same derivative.\n\nThe integral has various applications in mathematics and science, such as finding areas, calculating the total change of a quantity, determining the average value of a function, solving differential equations, and modeling continuous phenomena. It is a powerful tool that plays a crucial role in many areas of mathematics and has far-reaching applications in physics, engineering, economics, and other disciplines.', role='assistant', function_call=None, tool_calls=None))], created=1703531527, model='gpt-3.5-turbo-0613', object='chat.completion', system_fingerprint=None, usage=CompletionUsage(completion_tokens=251, prompt_tokens=37, total_tokens=288))

I tried out with gpt-4 model, and now it does!
