   • Consider upgrading to PRO account ($9/month) for higher quotas

⚠️ Important Notes

1. Usage Quota: Inference API and HuggingChat usage consumes monthly credits (Free ~$0.10/month, PRO ~$2/month), limitations apply when quota is exhausted
2. Rate Limits: Different account tiers have different rate limits, refer to official docs and actual API responses
3. Model Quality Variance: Open-source model performance varies, testing is needed to select suitable models
4. Cold Start Time: First call to a model may take longer (cold start)
5. Data Privacy: Be mindful of data privacy when using public models, use private deployment for sensitive data
