Use Gemini Omni Flash Preview with Comfy Router

Use gemini-interactions/gemini-omni-flash-preview with the Comfy Router API. Gemini Interactions provides the model; Router gives it the shared authentication and request route below.

Quick start

Create a key at platform.comfy.org/profile/api-keys and export it as COMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP. Model ID: gemini-interactions/gemini-omni-flash-preview Endpoint: POST https://api.comfy.org/v2/models/gemini-interactions/gemini-omni-flash-preview

import uuid
from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment. Save this key and reuse it if you
# retry this request after the SDK returns an error.
idempotency_key = str(uuid.uuid4())
with Comfy() as client:
    result = client.models.run(
        "gemini-interactions/gemini-omni-flash-preview",
        {
            # Request fields are the provider's own — see Input below.
        },
        idempotency_key=idempotency_key,
    )

print(result)

import { comfy } from "@comfyorg/sdk";

// Reads COMFY_API_KEY from the environment. Save this key and reuse it if you
// retry this request after the SDK returns an error.
const idempotencyKey = crypto.randomUUID();
const { data } = await comfy.models.run("gemini-interactions/gemini-omni-flash-preview", {
  // Request fields are the provider's own — see Input below.
}, { idempotencyKey });

console.log(data);

# Request fields are the provider's own — see Input below.
# Run this line once. Reuse ROUTER_REQUEST_KEY if you retry the curl command.
ROUTER_REQUEST_KEY=$(uuidgen)
curl https://api.comfy.org/v2/models/gemini-interactions/gemini-omni-flash-preview \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $ROUTER_REQUEST_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

Schema

Input

Router has not published an authored input schema for this model yet: GET /v2/models/gemini-interactions/gemini-omni-flash-preview/openapi.json returns an open object with x-comfy-input-schema-authored: false. Router forwards the body to Gemini Interactions unchanged, so Gemini Interactions’s own API reference is authoritative for the request fields, and nothing is validated server side.

Output

string

required

Always completed on a Router response. The provider’s other statuses (in_progress, requires_action, failed, cancelled, incomplete, budget_exceeded) do not reach a caller through Router as a 200; they are returned as a Comfy Router error carrying the provider’s body.Possible values: completed

object[]

required

The interaction timeline, in order. Narrowed here from the untyped steps on GeminiInteraction so the output leaf is addressable; the provider keeps adding step types, so an item is additionalProperties: true and only the fields a Router caller reads are declared.

object[]

The typed content blocks of this step.

string

Base64-encoded inline media, on a media block delivered inline. Google caps inline media at 4 MB and requires delivery: uri above it.

string

Media type of data or uri, on a media block.

string

The generated text. Present on a text block, and this is the leaf the nightly Router SDK case asserts (steps[].content[].text).

string

Block kind — text, image, audio, video or document.

string

Reference to media delivered out of band, fetched by the caller from the URI it names.

string

Step kind. model_output is the generated answer; user_input is the caller’s own turn echoed back by the retrieval route; thought is internal reasoning. The tool steps (function_call, function_result, code_execution_call, google_search_call, …) are open-ended and Google adds to them.

object

Token usage for a Gemini interaction.

object[]

Token count for one modality.

string

One of text, image, audio, video, document.

integer

object[]

Token count for one modality.

string

One of text, image, audio, video, document.

integer

Before you ship

Save one Idempotency-Key for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves. Use X-Comfy-Error-Type to classify a failure. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Using the Router API

Find models, inspect schemas, and retry safely.

Limitations

What Router does not do today, and what to use instead.
