Use Photon 1 with Comfy Router

API Reference for luma/photon-1, served by Comfy Router from Luma.

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: luma/photon-1 Endpoint: POST https://api.comfy.org/v2/models/luma/photon-1

from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment. Each call sends a fresh
# Idempotency-Key and waits up to 10 minutes for the finished result.
with Comfy() as client:
    result = client.models.run(
        "luma/photon-1",
        {
            # Request fields are the provider's own — see Input below.
        },
    )

print(result)

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

// Reads COMFY_API_KEY from the environment. Each call sends a fresh
// Idempotency-Key and waits up to 10 minutes for the finished result.
const { data } = await comfy.models.run("luma/photon-1", {
  // Request fields are the provider's own — see Input below.
});

console.log(data);

# Request fields are the provider's own — see Input below.
curl https://api.comfy.org/v2/models/luma/photon-1 \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'

Schema

Input

Router has not published an authored input schema for this model yet: GET /v2/models/luma/photon-1/openapi.json returns an open object with x-comfy-input-schema-authored: false. Router forwards the body to Luma unchanged, so Luma’s own API reference is authoritative for the request fields, and nothing is validated server side.

Output

object

The assets of an image generation. image is the result; video and progress_video belong to the Dream Machine VIDEO operation, which shares this status route, and Luma sends them here as explicit nulls.

string (uri)

The URL of the generated image — the leaf a luma/photon-* generation fills. Null until the generation reaches completed.Format: uri

string (uri)

Always null on an image generation; it is the in-flight preview Luma publishes while a VIDEO generation runs.Format: uri

string (uri)

Always null on an image generation; the luma/ray-* video models fill it instead.Format: uri

string (date-time)

The date and time when the generation was createdFormat: date-time

string

The reason for the state of the generation

string

The type of the generation — always image on this operationPossible values: image

string (uuid)

The ID of the generationFormat: uuid

string

The model used for the generation

object

The image generation request, echoed back inside the terminal document. Luma serialises every field of its request model, writing an explicit null into each one the caller did not set, so read a field’s presence from its VALUE rather than from the key.

string

default:"\"16:9\""

The aspect ratio of the generationPossible values: 1:1, 16:9, 9:16, 4:3, 3:4, 21:9, 9:21

string (uri)

The callback URL for the generationFormat: uri

object

An image identity as it comes BACK inside the terminal document. Same shape as LumaImageIdentity, with its members nullable for the reason LumaImageRefEcho gives.

string (uri)[]

The URLs of the image identity

string

Always image when set, echoing the operation. Null when the caller did not send one, for the reason this whole echo object exists.

object[]

An image reference as it comes BACK inside the terminal document. Same shape as LumaImageRef, with each member nullable because Luma echoes an unset one as an explicit null rather than omitting it.

string (uri)

The URL of the image referenceFormat: uri

number

The weight of the image reference

string

default:"\"photon-1\""

The image model used for the generationPossible values: photon-1, photon-flash-1

object

A modify-image reference as it comes BACK inside the terminal document. Same shape as LumaModifyImageRef, with its members nullable for the reason LumaImageRefEcho gives.

string (uri)

The URL of the image referenceFormat: uri

number

The weight of the modify image reference

string

The prompt of the generation

object[]

string (uri)

The URL of the image referenceFormat: uri

number

The weight of the image reference

string

The state of the generationPossible values: queued, dreaming, completed, failed

Before you ship

The snippets above are the shortest working call. Three things are the same for every model and are documented once on the Comfy Router headers page: send an Idempotency-Key on every paid call and reuse it when you retry, expect the connection to be held up to Router’s 10 minute deadline, and keep X-Comfy-Request-Id from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, X-Comfy-Error-Type names the bucket, and a 422 means the body failed the model’s schema and was never billed.

Headers

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

Quick Start

Typed error handling in Python and TypeScript, reading the 422, walking the catalog.

Limitations

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