How to handle AI errors in UX

Quick answer
Handle AI errors in UX by detecting API errors or model behavior issues and providing clear, actionable feedback to users. Implement retries, fallbacks, and validation to maintain a smooth experience without confusing or frustrating users.
ERROR TYPE api_error
⚡ QUICK FIX
Add exponential backoff retry logic around your API call to handle RateLimitError automatically.

Why this happens

AI errors in UX typically arise from API errors like rate limits, timeouts, or network failures, or from model behavior issues such as hallucinations or unexpected outputs. For example, calling the OpenAI API without retry logic can cause unhandled RateLimitError or TimeoutError, resulting in poor user experience.

Example broken code without error handling:

python
from openai import OpenAI
import os

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

response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Generate a summary"}]
)
print(response.choices[0].message.content)
output
Traceback (most recent call last):
  File "app.py", line 7, in <module>
    response = client.chat.completions.create(...)
  File "openai/api_resources/chat_completion.py", line 50, in create
    raise RateLimitError("You have exceeded your rate limit.")
openai.error.RateLimitError: You have exceeded your rate limit.

The fix

Wrap your API calls with retry logic using exponential backoff to handle transient errors like RateLimitError or TimeoutError. This prevents abrupt failures and improves UX by retrying automatically. Also, validate model outputs and provide fallback messages if the AI response is invalid or empty.

python
import time
from openai import OpenAI, RateLimitError, Timeout
import os

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

max_retries = 3
retry_delay = 1  # seconds

for attempt in range(max_retries):
    try:
        response = client.chat.completions.create(
            model="gpt-4o-mini",
            messages=[{"role": "user", "content": "Generate a summary"}]
        )
        text = response.choices[0].message.content
        if not text.strip():
            raise ValueError("Empty response from model")
        print(text)
        break
    except (RateLimitError, Timeout) as e:
        print(f"API error: {e}, retrying in {retry_delay} seconds...")
        time.sleep(retry_delay)
        retry_delay *= 2
    except Exception as e:
        print(f"Fatal error: {e}")
        break
output

Preventing it in production

  • Implement robust retry policies with exponential backoff for transient API errors.
  • Validate AI outputs to detect hallucinations or empty responses and fallback to safe defaults or user prompts.
  • Show clear, user-friendly error messages explaining issues and next steps.
  • Use circuit breakers to avoid overwhelming APIs during outages.
  • Log errors and monitor AI service health to proactively address issues.

Key Takeaways

  • Use exponential backoff retries to handle transient API errors gracefully.
  • Validate AI outputs to detect and handle unexpected or empty responses.
  • Provide clear, actionable error messages to users to maintain trust.
  • Implement monitoring and logging to catch and fix AI errors proactively.
