Text to 3D Model — P Series

http

Base URL: https://openapi.tripo3d.ai/v3

Endpoint: POST /generation/text-to-model

Generate a 3D model from a text prompt using P Series. Optimized for low-poly output with clean topology.

Note

This endpoint requires an API Key. Include it in the Authorization header as Bearer {api_key}.
This is an asynchronous API. After submitting the request, use the Task Query API to poll for results, or configure a Webhook to receive automatic notifications when the task completes.

Request Parameters

Request Body

promptstringRequired

Text prompt, up to 1024 characters. Describe shape, material, style, and scale.

Notes

Good: "A low-poly medieval wooden treasure chest with iron hinges and a rusty lock."
Bad: "A box."
Include material and style hints for better PBR results.

negative_promptstring

Negative prompt, up to 255 characters. Describe what you do NOT want in the generated model. For example: "blurry, low quality, broken mesh".

image_seedinteger

Random seed for the internal text-to-image stage. Controls the reference image generated from your text prompt before 3D conversion. If not set, a random seed is used each time.

modelstringRequired

P Series model version. Must be set to call the P Series; if omitted, the request runs on the default H Series model v3.1-20260211.

P1-20260311 — optimized for low-poly generation.
P2-20260801 — next-gen P Series with quad output support. Preview

model_seedinteger

Random seed for geometry generation. Using the same seed with the same input will produce an identical 3D mesh. If not set, a random seed is used each time.

face_limitinteger

Maximum polycount for the output mesh.

Notes

P1-20260311: 50 – 20,000
P2-20260801 triangle: 48 – 50,000; with quad=true: 48 – 25,000
If omitted, adaptively determined.

For best quality: simple models start from 150 faces, complex models start from 250 faces. Lower values may result in poor generation quality.

texturebooleandefault: true

Whether to generate texture maps for the model. Set to false to get a bare geometry without any textures. Default is true.

pbrbooleandefault: true

Enable PBR material maps (base_color, metallic, roughness, normal).

When pbr is set to true, texture will be automatically forced to true.

texture_seedinteger

Random seed for texture generation. Using the same seed will produce identical textures. If not set, a random seed will be used each time. To get a model with different textures but the same geometry, keep model_seed unchanged and vary texture_seed.

texture_qualitystringdefault: standard

Texture quality level.

fast — the fastest generation, trading texture detail for speed. Output texture size is identical to standard. Requires texture v3.5-20260815; costs the same as standard.
standard — balanced quality and speed.
detailed — higher fidelity, slower generation.
extreme — 8K textures, highest fidelity. Costs additional credits compared to detailed.

Notes

fast is only available on texture v3.5-20260815. On the generation endpoints that means texture_version must be set to it; on /v3/models/texture it means model. Any other texture version returns 1004 rather than silently falling back to standard.

texture_versionstring

Pins the texture model independently of the geometry model.

v3.5-20260815 — newest texture model. Required for texture_quality=fast and delight.
v3.0-20250812 — default for v3.x and P-series geometry.
v2.5-20250123 — default for v2.5-20250123 geometry.

If omitted, it is derived from the geometry model as listed above.

delightbooleandefault: true

Removes baked-in lighting from the reference image before texturing. Set false to keep the original shading. Only the v3.5-20260815 texture model reads this; older texture versions ignore it.

auto_sizebooleandefault: false

Whether to automatically scale the generated model to real-world dimensions. When enabled, the model size will be in meters, suitable for AR/VR or game engine scenes. Default is false.

export_uvbooleandefault: true

Controls UV unwrapping. Set false for faster generation and smaller file size.

export_orientationstringdefault: +x

Export orientation (forward axis).

+x — default, X-forward.
-x — negative X-forward.
-y — negative Y-forward.
+y — Y-forward.

Notes

Applies to this generation only. If the model will be used in post-processing tasks (texture, rig, retarget, convert, ...), it is recommended not to set this parameter.
When set, post-processing the model may produce a wrongly-oriented result while the task still reports status: success — no error is raised. Use with caution.
If you plan to post-process the model, leave this unset and convert the orientation in the last step via /v3/models/convert.

quadbooleandefault: false

P2-20260801 only. Whether to output a quad mesh (four-sided polygons) instead of triangles.
