What it excels at

Handles high-volume batch workloads with 1M context at very low input cost. Supports text, vision, and audio inputs in a single API call.

The business tradeoff

Lite optimization reduces depth on multi-step reasoning and complex instruction following. Output pricing remains higher relative to input, and quality lags non-lite Gemini variants.
