How to Use TRELLIS 2 Online Free: No GPU Required (2026)

Best for most people: Start with the official Hugging Face Space — it's free, unlimited, and hosted by Microsoft.

Method 1: Hugging Face Spaces (Recommended)

Microsoft hosts an official demo on Hugging Face Spaces. It's completely free with no registration required.

Official Image-to-3D Space

URL: huggingface.co/spaces/microsoft/TRELLIS.2

How to use it:

1. Open the link in your browser
2. Upload a PNG image (transparent background works best)
3. Adjust the resolution slider if needed
4. Click Generate
5. Wait ~5-10 seconds
6. Download your 3D model as GLB

Tips for best results:

• Use images with a transparent or solid-color background
• Center the subject and make sure it's fully visible
• Resolution of 512x512 or higher produces better results
• Even, diffused lighting produces cleaner geometry

Community Text-to-3D Space

URL: huggingface.co/spaces/prithivMLmods/TRELLIS.2-Text-to-3D

This community-maintained Space lets you generate 3D models from text descriptions using TRELLIS 2 combined with an image generation pipeline.

How to use it:

1. Open the link
2. Type a description of what you want (e.g., "a medieval helmet with gold engravings")
3. Click generate
4. Download the resulting 3D model

Prompt tips:

• Be specific about materials, colors, and shapes
• Include style keywords like "realistic", "low-poly", or "stylized"
• Avoid vague descriptions — "a sword" is less effective than "a double-edged steel longsword with a leather grip"

Limitations of Hugging Face Spaces

• Queue times: Popular Spaces may have a wait (typically 1-5 minutes during peak hours)
• Session limits: Long sessions may time out
• Resolution: Limited to 512³ on the free Space
• No batch processing: One image at a time

For higher resolution (1024³-1536³) or batch processing, see the other methods below.

Method 2: 3D AI Studio

3D AI Studio offers a free web interface for TRELLIS 2 with additional export format support.

Advantages over Hugging Face:

• Export in GLB, OBJ, and FBX formats
• Built-in 3D preview with orbit controls
• Supports PBR texture output (Base Color, Roughness, Metallic)

How to use it:

1. Go to 3daistudio.com/Models/Trellis-2
2. Upload your image
3. Configure output settings
4. Generate and download in your preferred format

Method 3: Trellis3D.co

Trellis3D.co is a free online tool for converting images to 3D assets using TRELLIS 2.

Features:

• Simple upload-and-generate workflow
• Multiple output format options
• No account required

Method 4: Google Colab (Free GPU)

If you need more control over generation parameters, Google Colab provides free GPU access (T4 with ~16 GB VRAM). Several community notebooks are available:

Community Colab Notebooks

• Reddit community notebook: Shared in r/Unity3D — "painless installation" with generation in minutes
• jackel27/Trellis-Colab: Available on GitHub — manual setup with CUDA 11.8 configuration

Colab Setup Steps

1. Open a TRELLIS 2 Colab notebook
2. Run the installation cells (first-time setup takes ~10-15 minutes)
3. Upload your image to the Colab workspace
4. Run the generation cell
5. Download the output model

Colab considerations:

• Free tier provides a T4 GPU (16 GB VRAM) — sufficient for 512³ resolution
• Sessions timeout after 12 hours of inactivity
• Installation steps need to be repeated on new sessions
• Colab Pro ($10/month) provides A100 GPUs for faster generation

Method 5: Replicate (Free Trial Credits)

Replicate runs TRELLIS 2 on A100 (80 GB) GPUs and supports the full resolution range up to 1536³.

Pricing: ~$0.82 per generation, but new accounts get free trial credits (typically enough for 5-10 generations).

Best for: Users who need maximum resolution (1536³) or want to test before committing to an API integration.

How to use it:

1. Sign up at replicate.com with your GitHub account
2. Navigate to fishwowater/trellis2
3. Upload an image or provide a URL
4. Configure parameters and click "Create prediction"
5. Download the result

Alternative models on Replicate:

• fishwowater/trellis-image — supports multiple image conditions (single image, multi-view, separate structure/texture control)

Method 6: fal.ai (Developer API)

fal.ai provides a production-ready API for TRELLIS 2 with transparent per-generation pricing.

Pricing:

• 512p: $0.25 per generation
• 1024p: $0.30 per generation
• 1536p: $0.35 per generation

Best for: Developers integrating 3D generation into their applications. fal.ai provides official API endpoints with low latency and high reliability.

Choosing the Right Platform

For Quick One-Off Generations

Use the official Hugging Face Space. No signup, no cost, and you get results in seconds. It's the simplest path from image to 3D model.

For Multiple Format Exports

Use 3D AI Studio. It offers GLB, OBJ, and FBX export with PBR textures, all for free.

For Maximum Quality

Use Replicate (with free trial credits) for 1536³ resolution on A100 GPUs. This gives you the highest quality TRELLIS 2 output available.

For Developers

Use fal.ai for API integration. It offers the best developer experience with official SDKs and predictable pricing.

For Learning and Experimentation

Use Google Colab. You get hands-on experience with the model, full parameter control, and the ability to modify the pipeline.

Preparing Your Image for Best Results

Regardless of which platform you choose, input quality determines output quality. Follow these guidelines:

Do:

• Use images with transparent backgrounds (PNG with alpha channel)
• Ensure the subject is centered and fully visible
• Use even, diffused lighting — avoid harsh shadows
• Aim for 512x512 resolution or higher
• Crop tightly around the subject

Don't:

• Use images with cluttered backgrounds
• Upload blurry or low-resolution photos
• Use images where the subject is partially occluded
• Expect perfect results from complex multi-object scenes

A well-prepared image can improve output quality by 30-50% compared to a random snapshot.

Export Format Guide

Different use cases call for different export formats:

Choose GLB if you're unsure — it's the most widely supported format.

Frequently Asked Questions

Is TRELLIS 2 really free to use online?

Yes. The official Hugging Face Space is completely free with no account required. Other platforms like 3D AI Studio and Trellis3D.co also offer free access. Paid platforms like Replicate and fal.ai charge per generation but offer higher resolution and better performance.

Can I use TRELLIS 2 on my phone?

The Hugging Face Space works in mobile browsers, but the experience is optimized for desktop. For the best experience, use a computer with a modern browser.

Do I need an NVIDIA GPU to use TRELLIS 2 online?

No. All the online platforms listed above run TRELLIS 2 on cloud GPUs. You only need a web browser.

What's the maximum resolution I can get for free?

The free Hugging Face Space supports up to 512³ resolution. For higher resolutions (1024³-1536³), use Replicate (with trial credits) or fal.ai.

Can I use the generated models commercially?

Yes. TRELLIS 2 is released under the MIT license, which permits commercial use. However, verify the license of any input images and check for trademark issues in generated content.

Which platform generates the fastest?

The Hugging Face Space typically generates results in 5-10 seconds. Replicate on A100 GPUs can generate in ~3 seconds at 512³ resolution.
