Gemini 3.7 Flash

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.

When to use Gemini 3.7 Flash

Updated 2026-08-14

Where this model earns its cost — and where it doesn't.

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.

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.

FAQ

Common questions about this model.

What is the context window of Gemini 3.7 Flash?

Gemini 3.7 Flash has a 1M-token context window — roughly 1542 pages of text in a single request.

How much does the Gemini 3.7 Flash API cost?

$0.5063 per 1M input tokens and $2.531 per 1M output tokens (on offer until Aug 21, then $1.013/$5.063), with cached input at $0.05061/1M — 90% off the input rate on repeated prompt prefixes. No subscription; you pay only for what you use.

Does Gemini 3.7 Flash support function calling?

Yes — Gemini 3.7 Flash supports tool/function calling and structured outputs (JSON mode), so it works with agent frameworks out of the box.

Are the weights for Gemini 3.7 Flash publicly available?

No. Google does not publish Gemini 3.7 Flash's weights — it is reachable through an API rather than as a file you can download and run (https://deepmind.google/models/model-cards/gemini-3-7-flash/, read 2026-08-14). That is Google's decision about their own product, not a limitation of Kyma.

Is Gemini 3.7 Flash ever served below the precision its creator released it at?

Kyma cannot say, and for this model nobody can. Google does not publish Gemini 3.7 Flash's weights, so there is no released checkpoint whose precision a route could be measured against. We publish "not established" rather than reading a low format as a downgrade: on several models in this catalogue a low format is exactly how the creator ships it.

How do I use Gemini 3.7 Flash?

Kyma is OpenAI-compatible: point your SDK's base URL at https://kymaapi.com/v1, use your Kyma API key, and set the model to gemini-3.7-flash. Signing up is free and includes $0.50 of credit — no card required.

How is this different from Gemini 3.6 Flash?

Two things: the output ceiling rises from 8,192 to 65,536 tokens, and structured outputs are supported where 3.6 Flash does not support them. Both models take a 1M-token context and both accept text, image, audio and video.

Does prompt caching work on this model?

Yes. Repeated prompt prefixes bill at this model's cached input rate, and the saving is reported per request in usage.cache_discount.

Can it accept file input?

Yes. Alongside text, image, audio and video, this tier accepts file input — the widest input set of any model in the Gemini Flash family on Kyma.
