Input Schema

20 parameters · 1 required · 19 optional

Parameter	Type	Required	Description
`image`	string	Required	URL of the input image to convert to 3D
`seed`	integer	Optional	Random seed for reproducibility
`remesh`	boolean	Optional	Rebuild the mesh topology for cleaner triangles. Slower but usually produces better results for downstream use. · Default: true
`mesh_scale`	number	Optional	Scale factor applied to the inferred mesh. Affects the camera distance estimation used by the model. · Min: 0.1 · Max: 4 · Default: 1
`resolution`	integer	Optional	Output resolution; higher is slower but more detailed · Options: 1024, 1536 · Default: 1024 10241536
`ss_rescale_t`	number	Optional	Controls noise schedule sharpness for structure generation. Higher values produce sharper transitions. · Min: 1 · Max: 6 · Default: 5
`texture_size`	integer	Optional	Resolution of the texture image baked onto the mesh. Higher values capture finer surface details but produce larger files. · Options: 1024, 2048, 4096 · Default: 2048 102420484096
`max_num_tokens`	integer	Optional	Maximum number of HR tokens used by the cascaded shape sampler. Higher values allow finer geometry; lower values reduce memory and time. · Min: 4096 · Max: 131072 · Default: 49152
`decimation_target`	integer	Optional	Target number of vertices in the final mesh. Lower values produce smaller files but less detail. · Min: 5000 · Max: 2000000 · Default: 200000
`ss_sampling_steps`	integer	Optional	Number of denoising steps for the initial structure. More steps = slower but potentially higher quality. · Min: 1 · Max: 50 · Default: 12
`tex_slat_rescale_t`	number	Optional	Controls noise schedule sharpness for texture generation. Higher values produce sharper texture details. · Min: 1 · Max: 6 · Default: 3
`ss_guidance_rescale`	number	Optional	Dampens artifacts from high guidance in stage 1. Lower values allow stronger guidance effects, higher values stabilize the output. · Min: 0 · Max: 1 · Default: 0.7
`shape_slat_rescale_t`	number	Optional	Controls noise schedule sharpness for shape refinement. Higher values produce sharper geometric details. · Min: 1 · Max: 6 · Default: 3
`ss_guidance_strength`	number	Optional	How closely the initial 3D structure follows the input image. Higher values produce more faithful but potentially noisier results. · Min: 0 · Max: 10 · Default: 7.5
`tex_slat_sampling_steps`	integer	Optional	Number of denoising steps for texture generation. More steps = slower but potentially cleaner textures. · Min: 1 · Max: 50 · Default: 12
`shape_slat_sampling_steps`	integer	Optional	Number of denoising steps for shape refinement. More steps = slower but potentially smoother geometry. · Min: 1 · Max: 50 · Default: 12
`tex_slat_guidance_rescale`	number	Optional	Dampens artifacts from high guidance in the texture stage. Increase if textures look noisy or have color banding. · Min: 0 · Max: 1 · Default: 0
`tex_slat_guidance_strength`	number	Optional	How closely the texture follows the input image colors. Higher values produce more vivid but potentially oversaturated textures. · Min: 0 · Max: 10 · Default: 1
`shape_slat_guidance_rescale`	number	Optional	Dampens artifacts from high guidance in the shape stage. Increase if you see noisy geometry. · Min: 0 · Max: 1 · Default: 0.5
`shape_slat_guidance_strength`	number	Optional	How closely the detailed geometry follows the input image. Higher values add more detail but may introduce noise. · Min: 0 · Max: 10 · Default: 7.5

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response
