Gemini 3.6 Flash API Pricing & Cost Calculator

How this is calculated

Gemini 3.6 Flash is priced at $1.50 per million input tokens and $7.50 per million output tokens, with a 90% prompt caching discount ($0.15 per million cached reads) and a 50% batch discount ($0.75 per million inputs, $3.75 per million outputs) via Google's Batch API. That's a touch cheaper than Gemini 3.5 Flash on output.

Verdict

Gemini 3.6 Flash sits at $1.50/M input and $7.50/M output, with the 90% cache discount dropping cached input to $0.15/M and the 50% batch discount dropping both to $0.75/M input and $3.75/M output. The multimodal case is what makes the per-token value stack: image, audio, and video inputs route through a single endpoint at the same per-million-token rate, so a video or audio transcription pipeline that would otherwise need transcription-plus-classification models collapses into one bill. The deeper 90% cache discount eclipses Gemini 3.5 Flash on cached workloads, and the batch-API 50% halves both rows for offline media processing jobs.
