Openai Gpt 6 Astra Image To 3d API Documentation
Playground
Try it on WaveSpeedAI!GPT-6 Astra Image-to-3D generates textured 3D models or scenes from reference images, with optional text guidance for image-guided 3D asset creation, product visualization, concept design, virtual scenes, and production workflows. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.
Features
GPT-6 Astra Image to 3D turns reference images into a textured 3D object or scene that can be rotated, explored, and developed further. Provide one or more images, add optional prompt guidance, set the subject scale, and generate a portable GLB model for downstream 3D workflows.
Why Choose This?
-
Image-to-3D generation
Convert reference images into a generated 3D object or scene. -
Object and scene creation
Generate standalone products, props, vehicles, interiors, buildings, environments, or broader spatial concepts. -
Material-aware output
Guide materials such as timber, stone, glass, painted metal, fabric, ceramic, or worn surfaces through the prompt. -
PBR texture support
The exported model includes geometry and embedded PBR textures. -
Portable GLB output
Download a GLB model that can be viewed in compatible browser viewers or imported into 3D applications.
Parameters
| Parameter | Required | Description |
|---|---|---|
| images | Yes | Reference image URLs. Supports up to 10 images. |
| prompt | No | Optional guidance for the subject, materials, surroundings, or scene interpretation. Maximum length: 4000 characters. |
| size | No | Longest subject dimension in meters. Range: 0.05–20. Default: 1. |
How to Use
- Provide reference images — Upload images of the subject or scene you want to convert into 3D.
- Add prompt guidance optional — Describe the subject, materials, hidden details, or surrounding environment.
- Set size optional — Define the longest subject dimension when a specific physical scale is needed.
- Submit — Generate the 3D result.
- Download the GLB — Retrieve the generated GLB model URL from
outputs.
Pricing
Pricing is fixed at $8 per generation.
| Output | Cost |
|---|---|
| One GLB model generation | $8.00 |
Output
Each successful request returns a GLB model URL in outputs.
The generated model includes geometry and embedded PBR textures. Tasks have a 120-minute timeout.
Best Use Cases
- Product visualization — Turn product references into 3D assets for inspection and presentation.
- Concept design — Explore objects, vehicles, architecture, props, interiors, and environments in 3D.
- Scene prototyping — Generate spatial concepts such as rooms, courtyards, workshops, hangars, or landscapes.
- Interactive experiences — Create starting assets for viewers, prototypes, games, or immersive workflows.
- Creative iteration — Compare multiple design directions from the same set of reference images.
Pro Tips
- Use clear, consistent reference images of the same subject.
- Add multiple angles when shape and proportions matter.
- Use the prompt to explain details that are hidden, ambiguous, or not visible in the images.
- For scenes, describe both the main subject and the surrounding space.
- Include material details such as surface wear, glass, metal, stone, fabric, or wood when appearance matters.
- Inspect the first result from several angles before refining the next prompt.
- Generated assets may need cleanup for production use.
- The result is a generated interpretation, not a dimensionally exact scan.
Example Prompt
A compact exploration spacecraft resting on three landing legs inside a service hangar. Give it a rounded ceramic hull, a smoked-glass cockpit, recessed engine nozzles, and visible panel seams. Include maintenance carts and a grated floor, with enough space to inspect the craft from all sides.
Notes
imagesis required.- Up to
10reference images are supported. promptis optional and supports up to4000characters.sizecontrols the longest subject dimension in meters.- Exact likeness, physical accuracy, and photorealism are not guaranteed.
- Lighting and material appearance may vary by 3D viewer.
