Superseded by Gemini 3.8 Flash, but still available by model ID and unchanged for anyone already on it. 3.8 Flash lists at the same rate with the same 1M context and 64K output ceiling and is Google's stronger model on software-engineering and agentic work — start new work there.

Tick above each rail is this model, below it the other 70. Dashed rule is the field median, solid is its best. Better is left; the axis stops at the 90th percentile, so a few models sit past its right edge.

How it behaves under real clients
The same model answering different prompt shapes — measured, not benchmarked.
| Client | Requests | Tokens | Throughput | To first token | p95 total | Completed |
|---|---|---|---|---|---|---|
| Go App | 12,112 | 27.9M | 94 tok/s | 8.47 s | 12 s | 52% |
| Python App | 11,199 | 41.5M | 19 tok/s | 6.71 s | 28 s | 74% |
| Pheme | 126 | 828.3K | 95 tok/s | 5.47 s | 20 s | 98.4% |
Grouped by the client that sent the request. Not a benchmark: the same model on different prompt shapes. Throughput and time-to-first-token are medians; p95 is the slowest response in twenty. 1 client under 100 requests not shown.

When to use Gemini 3.7 Flash
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.
