## Positioning

Google's newest Flash tier, and the first in the family to pair a 1M-token context with a 64K output ceiling — eight times what 3.6 Flash and 3.5 Flash Lite will emit in one response.

## About

Gemini 3.7 Flash is Google's August 2026 Flash-tier release. It accepts text, image, audio, video and file input and returns text, and unlike the 3.6 tier it supports structured outputs alongside tool calling and reasoning.

The practical difference from the rest of the Flash family is the output ceiling: 65,536 tokens against 8,192 on 3.6 Flash and 3.5 Flash Lite. Work that had to be chunked because the reply would not fit — full document translations, long structured extractions, whole-file rewrites — fits in one request.

On Kyma it serves through an OpenAI-compatible endpoint with automatic failover to a second independent route. Prompt caching is supported and repeated prefixes bill at this model's cached input rate. Every response carries the exact request cost in usage.cost and names the model that answered in the X-Kyma-Model header.

## Use cases

- **Long-form structured extraction**, Reads a 1M-token corpus and emits tens of thousands of tokens of schema-constrained JSON in a single response.
- **Whole-document translation and rewriting**, The 64K output ceiling fits an entire long document's rewritten text without splitting the job into chunks.
- **Multimedia review**, Takes video, audio and images alongside a text prompt and returns a long written analysis in one pass.
- **High-volume multimodal agents**, Tool calling, reasoning and structured outputs on one request, at the Flash tier's cost and latency.

## Not ideal for

Do not reach for this when a short reply is all you need and cost is the deciding factor — the cheaper Flash tiers answer the same short prompts, and the large output ceiling buys nothing you will use.

## Pick something else when

- You need the cheapest 1M-context tier and replies stay short → `gemini-3.5-flash-lite`
- You want the previous Flash generation at the same list rate → `gemini-3.6-flash`
- You need reasoning tuned for code rather than for mixed media → `qwen-3-coder`, `kimi-k3`
