About

Text-to-3D generation using Rodin Gen-2.5

1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Migrate to @fal-ai/client

The @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Please check the migration guide for more information.

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

import { fal } from "@fal-ai/client";

const result = await fal.subscribe("fal-ai/hyper3d/rodin/v2.5/text-to-3d", {
  input: {
    prompt: "A futuristic robot with sleek metallic design."
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In case your app is running in an environment where you cannot set environment variables, you can set the API Key manually as a client configuration.

import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_KEY"
});

Protect your API Key

When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.

3. Queue#

Long-running requests

For long-running requests, such as training jobs or models with slower inference times, it is recommended to check the Queue status and rely on Webhooks instead of blocking while waiting for the result.

Submit a request#

The client API provides a convenient way to submit requests to the model.

import { fal } from "@fal-ai/client";

const { request_id } = await fal.queue.submit("fal-ai/hyper3d/rodin/v2.5/text-to-3d", {
  input: {
    prompt: "A futuristic robot with sleek metallic design."
  },
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

import { fal } from "@fal-ai/client";

const status = await fal.queue.status("fal-ai/hyper3d/rodin/v2.5/text-to-3d", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

import { fal } from "@fal-ai/client";

const result = await fal.queue.result("fal-ai/hyper3d/rodin/v2.5/text-to-3d", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

import { fal } from "@fal-ai/client";

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Auto uploads

The client will auto-upload the file for you if you pass a binary object (e.g. File, Data).

Read more about file handling in our file upload guide.

5. Schema#

Input#

prompt string* required

A textual prompt to guide model generation. Required for Text-to-3D mode.

tier TierEnum

Generation tier. Higher tiers produce more detailed meshes but cost more. Extreme-High enables the highest-detail mode and bills at double the base rate. See more info in the documentation. Default value: "Gen-2.5-Medium"

Possible enum values: Gen-2.5-Extreme-Low, Gen-2.5-Low, Gen-2.5-Medium, Gen-2.5-High, Gen-2.5-Extreme-High

seed integer

Seed value for randomization, ranging from 0 to 65535. Optional.

geometry_file_format GeometryFileFormatEnum

Format of the geometry file. Possible values: glb, usdz, fbx, obj, stl. Default is glb. Default value: "glb"

Possible enum values: glb, usdz, fbx, obj, stl

material MaterialEnum

Material type. PBR: physically-based materials with realistic lighting. Shaded: baked lighting with no PBR maps. All: both PBR and Shaded variants. None: geometry only with no textures. Default value: "All"

Possible enum values: PBR, Shaded, All, None

quality_mesh_option QualityMeshOptionEnum

Combined quality and mesh type selection. Quad = smooth surfaces, Triangle = detailed geometry. Maps to mesh_mode (Quad/Raw) and quality_override (face count) on the Hyper3D API. Valid face counts depend on the selected tier. Default value: "18K Quad"

Possible enum values: 4K Quad, 8K Quad, 18K Quad, 50K Quad, 2K Triangle, 20K Triangle, 150K Triangle, 500K Triangle

texture_mode Enum

Texture generation quality. When unset, the API picks a default appropriate for the tier.

Possible enum values: legacy, extreme-low, low, medium, high

geometry_instruct_mode GeometryInstructModeEnum

Faithful mode follows the prompt closely; creative mode permits more variation. Only effective in the Medium and High tiers. Default value: "faithful"

Possible enum values: faithful, creative

hd_texture boolean

Enables enhanced texture post-processing for higher visual fidelity.

texture_delight boolean

Removes baked lighting/highlights from the generated textures.

is_symmetric IsSymmetricEnum

Symmetry mode for the generated mesh. symmetric forces left-right symmetry; balanced favors symmetry without enforcing it; asymmetric allows freely asymmetric geometry; unknown lets the model decide based on the inputs. Default value: "unknown"

Possible enum values: symmetric, balanced, asymmetric, unknown

is_micro boolean

Generate finer micro-scale geometric detail. Only effective with tier="Gen-2.5-Extreme-High".

TAPose boolean

Generate characters in T-pose or A-pose format, making them easier to rig and animate in 3D software.

bbox_condition list<integer>

An array that specifies the bounding box dimensions [width, height, length]. Must be exactly three positive integers.

addons list<string>

Optional add-ons. Possible values are HighPack. HighPack provides 4K resolution textures and high-poly geometry, instead of default 2K. If in quality_mesh_option Quad is selected, the number of faces will be ~16 times of the number of faces selected in the quality part. Single values are accepted as a shorthand for a list with one item.

{
  "prompt": "A futuristic robot with sleek metallic design.",
  "tier": "Gen-2.5-Medium",
  "geometry_file_format": "glb",
  "material": "All",
  "quality_mesh_option": "18K Quad",
  "geometry_instruct_mode": "faithful",
  "is_symmetric": "unknown"
}

Output#

model_mesh File* required

seed integer* required

Seed value used for generation.

textures list<Image>* required

Generated textures for the 3D object.
