Trellis

THREE_DFeaturedmicrosoft-trellis

Trellis is an open-source 3D generation model from Microsoft Research that focuses on creating high-quality 3D objects with realistic materials and geometry from text prompts. It is known for its ability to produce detailed and coherent shapes, making it a valuable tool for researchers and hobbyists in the AI art community. As an open-source project, it offers a transparent and customizable foundation for exploring the future of 3D content creation.

workspace_id
required
Workspace Id

Id of the workspace that owns the resource.

string format: uuid

Id of the workspace that owns the resource.

session_name
Session Name

Organize this run under a named session. A new session is created if none matches.

string
nullable

Organize this run under a named session. A new session is created if none matches.

Idempotency-Key
string
<= 255 characters

Opaque key making a retry of this request return the first result. A 2xx response is replayed for 24 hours with Idempotent-Replayed: true. A 4xx releases the key. A 5xx, or a request still running, holds the key for 120 seconds, during which a retry gets 409; after that a retry executes again. The key covers the method, path, query, and byte-identical body it was first used with; reusing it for a different request is rejected with 422. Protection is best effort: if the key store is unavailable, or a record is lost early, a retry can execute again even after an earlier 409. See the Idempotency section of the API description.

seed
Seed

The starting point for the model’s randomness. The same seed and settings give the same result.

Advanced field.

integer
nullable
guidance_file_init_image
required
Source image

The image the 3D model is built from

Array<object>
>= 1 items
InferenceFormFileRef

A single guidance/reference file supplied to a reference_image_list field.

The slot’s guidance type is fixed by the field it’s attached to; the caller supplies the file (its URL, or the id of a file it can read) and, where the model supports per-file weighting, a weight.

object
url
required
Url

The file’s URL, or the id of a file in this workspace or a public file.
