OpenAIContentPolicyViolationError

openai.OpenAIContentPolicyViolationError

What this error means
OpenAI's API rejected the request because the input or output content violated the platform's content policy.

Stack trace

traceback
openai.OpenAIContentPolicyViolationError: The request was rejected because it violates OpenAI's content policy. Details: {"message": "Content policy violation detected.", "type": "content_policy_error", "param": null, "code": "content_policy_violation"}
QUICK FIX
Sanitize inputs and add prompt instructions to avoid disallowed content, then retry the request.

Why it happens

OpenAI enforces strict content policies to prevent generation or processing of harmful, illegal, or disallowed content. If the input prompt or the generated output contains flagged content, the API returns this error to block the request.

Detection

Monitor API responses for HTTP 403 errors with content_policy_violation codes and log the input prompt and output to identify policy violations before retrying.

Causes & fixes

1

Input prompt contains disallowed or flagged content such as hate speech, adult content, or illegal instructions.

✓ Fix

Sanitize and filter user inputs before sending to the API to ensure compliance with OpenAI's content policy.

2

The model generated output that violates content policy despite a compliant prompt.

✓ Fix

Add stricter prompt instructions to avoid triggering disallowed content and use moderation endpoints to pre-check outputs.

3

Using a model or prompt that encourages or implicitly requests disallowed content generation.

✓ Fix

Revise prompts to be neutral and policy-compliant, and switch to safer or instruction-tuned models that better adhere to content guidelines.

Code: broken vs fixed

Broken - triggers the error
python
from openai import OpenAI
import os

client = OpenAI(api_key=os.environ['OPENAI_API_KEY'])

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Generate hateful content about group X."}]
)  # This triggers content policy violation error
Fixed - works correctly
python
from openai import OpenAI, OpenAIContentPolicyViolationError
import os

client = OpenAI(api_key=os.environ['OPENAI_API_KEY'])

try:
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[{"role": "user", "content": "Generate a positive message about group X."}]  # sanitized prompt
    )
    print(response.choices[0].message.content)
except OpenAIContentPolicyViolationError as e:
    print(f"Content policy violation: {e}")  # handle violation gracefully
Sanitized the prompt to comply with content policy and added exception handling for content policy violations.

Workaround

Catch the OpenAIContentPolicyViolationError exception, log the flagged prompt, and return a user-friendly message asking to modify the input.

Prevention

Implement input validation and filtering layers before API calls and use OpenAI's moderation API to pre-check prompts and outputs to avoid policy violations.
