# Gemini 3.7 Flash — API pricing & integration guide | Y-API

> Gemini 3.7 Flash is a multimodal entry built for fast agentic workflows, coding and multi-step reasoning, with a 1,048,576-token window over text, image, video, file and audio input.

Model ID: `google/gemini-3.7-flash`

Sources reviewed: 2026-10-11. Y-API catalog snapshot: 2026-10-11.

## Choosing this model

Selection advice by Y-API. The checks below are suggested evaluations, not published test results.

### Where to start

Use it for tasks that need responsive iteration with reliable multi-step execution: an agent that reads a tool result and immediately decides the next call, or a coding loop that runs many short cycles.

### What to watch for

Google deprecated this model on 2026-10-08: requests to it are automatically routed to 3.8 Flash, and its price has been withdrawn from the rate card. The window and the gateway’s media forwarding are unchanged, but what answers a call is no longer this model — pin the model string you actually want. Media input support still needs its own check against the gateway.

## Model specifications

These are OpenRouter model-level specifications, not a Y-API compatibility test. A particular route may accept fewer input formats, parameters or tokens. Verify the features you need with a small request; a successful text response does not validate vision or tool calling.

| Field | Value |
| --- | --- |
| Context window | 1,048,576 tokens |
| Input | Text, Image, Video, File, Audio |
| Output | Text |
| Listed on OpenRouter | 2026-08-13 |
| Parameters listed by OpenRouter | `include_reasoning`, `max_tokens`, `reasoning`, `reasoning_effort`, `response_format`, `seed`, `stop`, `structured_outputs`, `temperature`, `tool_choice`, `tools`, `top_p` |

## API pricing & cost estimate

| Price basis | Input / 1M tokens | Output / 1M tokens |
| --- | --- | --- |
| Account credit | $1.50 | $7.50 |
| Cash equivalent | $0.15 | $0.75 |

$1 paid adds $10 of credit. Cash equivalent = credit consumed ÷ 10; this is not the model publisher’s list price.

Input tokens / request: 1000. Output tokens / request: 500. Number of requests: 1000.

Estimated credit consumed: $5.25. Estimated cash equivalent: $0.525.

Illustrative token budget, not measured usage or a quote. Includes input and output; excludes separate media charges, cache discounts and retries. Include billed reasoning tokens in your output budget where applicable. Actual billing follows usage returned by the service.

### Same token budget, different models

| Model | Estimated credit consumed | Estimated cash equivalent |
| --- | --- | --- |
| [Gemini 3.7 Flash](https://y-api.bestvirtualgoods.com/models/google/gemini-3.7-flash) | $5.25 | $0.525 |
| [Gemini 3.8 Flash](https://y-api.bestvirtualgoods.com/models/google/gemini-3.8-flash) | $5.25 | $0.525 |
| [Gemini 3.5 Flash](https://y-api.bestvirtualgoods.com/models/google/gemini-3.5-flash) | $8.00 | $0.80 |

## API integration examples

These minimal, text-only requests use the exact Y-API model ID. They do not demonstrate image, audio, video, file or tool support. The output limit also needs room for reasoning; an empty answer with finish_reason=length can mean the budget was exhausted.

Set the TOKEN environment variable to a key from your console. Run this on your server or locally; never expose a key in browser code or a public repository.

### A task to try

Given the last three tool outputs, decide the next call and state the stopping condition for this loop.

```bash
curl --fail-with-body --silent --show-error --max-time 120 \
  'https://api.y-api.bestvirtualgoods.com/v1/chat/completions' \
  -H "Authorization: Bearer ${TOKEN:?Set TOKEN first}" \
  -H 'Content-Type: application/json' \
  --data-binary @- <<'JSON'
{
  "model": "google/gemini-3.7-flash",
  "messages": [
    {
      "role": "user",
      "content": "Given the last three tool outputs, decide the next call and state the stopping condition for this loop."
    }
  ],
  "max_tokens": 4096
}
JSON
```

```python
import json
import os
import sys
import urllib.error
import urllib.request

payload = {
  "model": "google/gemini-3.7-flash",
  "messages": [
    {
      "role": "user",
      "content": "Given the last three tool outputs, decide the next call and state the stopping condition for this loop."
    }
  ],
  "max_tokens": 4096
}

request = urllib.request.Request(
    "https://api.y-api.bestvirtualgoods.com/v1/chat/completions",
    data=json.dumps(payload).encode("utf-8"),
    headers={
        "Authorization": "Bearer " + os.environ["TOKEN"],
        "Content-Type": "application/json",
    },
    method="POST",
)
try:
    with urllib.request.urlopen(request, timeout=120) as response:
        result = json.load(response)
    print(json.dumps(result, ensure_ascii=False, indent=2))
except urllib.error.HTTPError as error:
    print(error.read().decode("utf-8"), file=sys.stderr)
    raise SystemExit(1)
```

### How to evaluate the result

Run the loop on a task with a known solution and count how many steps it takes, whether it terminates on its own, and whether it repeats a failed call instead of changing approach.

## Before you choose

### Is 3.7 Flash slower or faster than 3.8 Flash?

The question no longer has an answer on this entry: Google deprecated 3.7 Flash on 2026-10-08 and routes its requests to 3.8 Flash, so a call to either name lands on the same model. Call 3.8 Flash directly and measure that.

## Sources & scope

Technical facts come from the cited model page and, where available, its linked publisher card. A card describes that checkpoint; it is not proof of the weights a gateway serves. Prices come only from the Y-API catalog. We do not claim measured latency, uptime or benchmark scores for this endpoint.

## Models to compare

Compare these alternatives on the same inputs. Their descriptions explain different roles; a lower price does not establish equivalent quality.

### [Gemini 3.8 Flash](https://y-api.bestvirtualgoods.com/models/google/gemini-3.8-flash)

Gemini 3.8 Flash is the newest Flash-tier entry from Google, with a 1,048,576-token window and text, image, video, file and audio input. The publisher describes it as improving on 3.7 Flash in software engineering and multi-step reasoning.

### [Gemini 3.5 Flash](https://y-api.bestvirtualgoods.com/models/google/gemini-3.5-flash)

Gemini 3.5 Flash is a multimodal Flash-tier entry from Google, accepting text, image, video, file and audio input over a 1,048,576-token window. The publisher positions it for coding proficiency and parallel agentic execution.
