Gemini 3.6 Flash — Google Model via reAPI Text Chat

Gemini 3.6 Flash is Google's Stable Gemini 3 model for fast, capable generation. Google documents multimodal input, thinking, function calling, and grounding for the underlying model. The current reAPI endpoint exposes a narrower text-only Chat Completions contract: each message `content` must be a string, streaming is supported, and `max_tokens` is capped at 8,192. Current pricing is shown in the table on this page.

What is the Gemini 3.6 Flash API?

Gemini 3.6 Flash is Google's Stable Gemini 3 model, served here through `https://reapi.ai/api/v1/chat/completions`. Requests use the standard Chat Completions format and are passed to the model as written, so parameters behave the way that format describes. Output is text, and a single response is capped at 8,192 tokens. Use the pricing table on this page for the current input and output rates.

What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

Gemini 3.6 Flash summarizing long plain-text material through reAPI

Summarize and compare long plain-text material

Send reports, notes, transcripts, or source excerpts as plain-text string content and ask Gemini 3.6 Flash to summarize, compare, extract decisions, or draft a response. The current endpoint does not upload PDF files or other media, so convert source material to text before sending it. This keeps the request shape simple and auditable.

Read the API docs
Gemini 3.6 Flash explaining code and generating structured text

Code explanation and structured text generation

Paste code, logs, schemas, or requirements as text and ask for an explanation, refactor, test plan, or structured draft. The endpoint returns text and may display reasoning only when the server returns it. It does not accept `tools`, execute code, or perform grounded web search, so applications should run any external actions themselves.

Gemini 3.6 Flash streaming a plain-text response through reAPI

Responsive chat with optional streaming

Set `stream` to `true` to render text chunks as they arrive, or `false` to wait for one JSON response. This fits support assistants, editing flows, classification, and summarization pipelines that work entirely with text. Set `max_tokens` no higher than 8,192 and use the live pricing table on this page to estimate cost.

Why reAPI

Current rates shown on this page

Gemini 3.6 Flash usage is priced separately for input and output tokens. The pricing table on this page is the source for the current rates; request cost depends on the text tokens actually processed and generated.

A focused Chat Completions contract

The current endpoint is `https://reapi.ai/api/v1/chat/completions`. Send the model, plain-text messages, optional `stream`, and optional `max_tokens`; unsupported multimodal parts, tools, and sampling fields are rejected instead of being silently ignored.

Use your current reAPI account and key

Create or manage the API key in your reAPI account, then authenticate requests to the same reAPI domain. The model-page Playground can also use your signed-in session without exposing a provider credential in the browser.

Gemini 3.6 Flash vs Gemini 3.5 Flash

This compares the underlying Google models using Google's published specifications, not the narrower current reAPI endpoint. Google lists the same limits, inputs, and capability set for both; their published output rates and release recency differ.

Ship Gemini 3.6 Flash in three steps

  1. step 01

    Create a reAPI account and key

    Sign in to your current reAPI account and create an API key under Settings. Keep the key server-side and send it as a Bearer token for external API requests.

    Open
  2. step 02

    Point your client at the current endpoint

    Set the OpenAI-compatible base URL to `https://reapi.ai/api/v1` and use the key from your reAPI account. The complete endpoint is `https://reapi.ai/api/v1/chat/completions`.

    Open
  3. step 03

    Send `gemini-3.6-flash` as the model

    Set `model` to `gemini-3.6-flash`, provide plain-text string `content` in `messages`, and optionally set `stream`. Keep `max_tokens` at or below 8,192; do not send media content parts or `tools` to this endpoint.

Parameter validation failed

Rejected synchronously with the failing field named. Check enum values, ranges, and URL fields — nothing is charged.

Authentication or balance issue

401 means a missing or invalid Bearer key; 402 means the reserve exceeds your balance. Manage keys and credits in the console.

Content or material rejected

Reference material and outputs pass automated moderation. Rejected tasks fail with a clear error and a full refund.

Task failed or timed out

A task that reaches a failed state is never charged — the reserve refunds automatically. Keep the task id and retry when ready.

Frequently asked questions

Common questions about this model.

Input and output tokens are priced separately. Use the dynamic pricing table on this page for the current rates; the total depends on the text tokens processed and generated by the request.
