Troubleshooting
Rate limit errors (429)
Rate limit errors (429)
Cause: Too many requests to OpenAI APISolutions:
- Implement request throttling
- Use exponential backoff retries
- Upgrade your OpenAI API tier
- Switch to GPT-4o Mini for high-volume use
Context length exceeded
Context length exceeded
Cause: Input + completion tokens exceed model’s context windowSolutions:
- Truncate conversation history
- Use models with larger context (GPT-5: 200K)
- Implement sliding window for message history
Slow responses with O1 models
Slow responses with O1 models
Expected behavior: Reasoning models take longerSolutions:
- Set user expectations (show “thinking…” indicator)
- Use O1 Mini instead of O1 for faster responses
- Reserve reasoning models for truly complex tasks
High costs
High costs
Solutions:
- Use GPT-5 Mini or GPT-4o Mini for most tasks
- Implement dynamic model selection
- Cache common responses
- Set max_tokens to limit completion length
