AI Engine Differences

Standard Engine — Gemini 2.5 Flash

Used for Sandbox tier. Optimized for speed and cost-efficiency. Excellent for development, testing, and lower-volume production use cases. Achieves sub-200ms latency on most payloads.

Advanced Engine — Gemini 2.5 Pro

Used for Startup and Scale tiers. Maximum accuracy for nuanced content — subtle financial manipulation, indirect PII inference, sophisticated adversarial prompting chains. Recommended for production deployments serving real users.
