⚠️ Free API Usage Limits
Gemini Free Tier limits apply per project, not per API key.
- Approximately 20–50 requests per day per model (varies by Google policy)
- Free tier quotas were significantly reduced after December 2025
- Exceeding the limit may cause analysis delays or errors
✅ Overcome Limits with Smart Routing
Eat-Story automatically rotates between 3 Gemini models (1.5 / 2.5 / 2.5 Lite), effectively extending your daily usable requests to approximately 60–150 per day. For heavier usage, switch to a paid plan or add keys for OpenAI or Claude.
