fix: Handle OpenAI API rate limiting and quota exhaustion in VC response generation

[hyunjimoon]

Based on the error log, I'll create a structured issue summary:

OpenAI API Rate Limit Error in VC Response Generation

Expected Behavior

Generate and save VC responses to a CSV file through multiple API calls

Current Behavior

Script fails with RateLimitError after ~100 successful API calls due to quota exhaustion:

openai.RateLimitError: Error code: 429 - {'error': {'message': 'You exceeded your current quota'}}

Steps to Reproduce

1. Run 1sim_vc_responses.py
2. Make multiple OpenAI API calls in sequence
3. Observe script failure after quota depletion

Context

• Environment: Python 3.12, OpenAI API
• Location: decode(venturing) project
• Script: 1sim_vc_responses.py

Possible Solution

1. Implement rate limiting and request batching
2. Add retry logic with exponential backoff
3. Check and monitor API quota usage
4. Consider upgrading OpenAI plan for higher quota

Implementation Suggestion

import time
from tenacity import retry, wait_exponential

@retry(wait=wait_exponential(multiplier=1, min=4, max=20))
def generate_with_backoff(client, prompt):
    time.sleep(0.1)  # Rate limiting
    return client.chat.completions.create(prompt)
