Is Trellis 2 Free? Official Pricing & Free Usage Guide (2026)

Last updated: October 25, 2026

Quick Answer: Yes and No

Yes and no. It depends which "Trellis 2" you mean.

The model is free. TRELLIS.2 was released by Microsoft Research as a 4-billion-parameter image-to-3D model under the MIT license. You can download the weights, run them on your own hardware, modify the code, and use the generated assets commercially. There are no royalties, no per-generation fees, and no attribution requirement.

The official cloud platform (this site) is paid, with plans starting at $19/month. What you pay for is skipping the 24GB GPU, the CUDA setup, and the command-line workflow.

This page is the official source for Trellis2.app pricing. The numbers below match the pricing page. If a third-party site quotes different prices for "Trellis 2", it is selling its own service, not the official platform.

Disclosure: we operate Trellis2.app, one of the options compared here. The model itself belongs to Microsoft Research; we are an independent platform that hosts it. Verify licence claims at github.com/microsoft/TRELLIS.2 and the 24GB requirement in the repository README. Want to try a generation now? The generator runs in the browser — sign up, and your Starter plan credit allowance covers the first tests.

What's Free Forever: The Open-Source Model

Microsoft Research published TRELLIS.2 on GitHub under the MIT license (microsoft/TRELLIS.2). Two things stay free:

• Weights and code. Clone the repository, download the 4B model from Hugging Face, run inference locally, modify it, build products on it. MIT permits all of this, for commercial work as well.
• Your outputs. Models you generate on your own hardware are yours: games, 3D printing, e-commerce previews, or client work.

The Real Requirement: A 24GB GPU

The official repository lists an NVIDIA GPU with at least 24GB of memory as the minimum, verified on A100 and H100. It also expects Linux, a CUDA toolkit (12.4 recommended), and Conda for the Python environment.

That is the only requirement. There is no account, no credit card, no per-generation meter, but there is a hardware bill and a setup session before your first result.

Official Platform Plans

The Trellis2.app platform runs TRELLIS.2 on managed infrastructure. Generation happens in the browser: no GPU, no Python, no installation.

Annual billing is available on every plan. Credits reset each month, and each generation costs 1–3 credits depending on the output resolution tier (low / standard / high). At 2 credits, the default 1024³ setting, Starter's 15 credits buy about 7 generations a month; Pro's 50 buy about 25, Business's 120 about 60. Low-resolution runs stretch that further; 1536³ runs cost the most. The live credit breakdown is on the pricing page.

What You Actually Get

• Up to 1536³ voxels with full PBR output: base color, metallic, roughness, and opacity
• The same 4B model and the same inference settings as the official release
• Browser workflow: upload an image, preview the GLB in 3D, download for Blender, Unity, or Unreal

Official Platform vs Wrapper Platforms: Check Before You Pay

Search "Trellis 2" and you will find several third-party sites reselling access under their own credit systems. Their prices change, so we will not quote them. Here is the checklist that matters:

A Reality Check on Generation Times

Third-party pages describe Trellis 2 generation times anywhere from "20 seconds" to "4–8 minutes." Those numbers describe their infrastructure, not the model.

Microsoft's published benchmarks, measured on an H100:

Local and cloud times vary with hardware, queue depth, and post-processing. But if a generation takes 4–8 minutes, it is worth asking what is actually running behind the page.

The Hidden Cost of "Free": Running It Yourself

The open-source route is free in licensing terms. Budget it honestly:

• GPU: a 24GB-class card (RTX 3090, RTX 4090, A100), roughly $1,000–1,600 used or new, or about $0.30–0.60/hour rented
• Setup time: CUDA toolkit, Conda environment, compiled submodules (flash-attn, o-voxel, cumesh, nvdiffrast, nvdiffrec), model download (the 4B checkpoint is a sizeable pull), then debugging driver and dependency mismatches
• Throughput: one consumer GPU is one queue. Batches of assets take minutes each, serially

For developers who already own the hardware and like the CLI, this is hard to beat. For everyone else, $19/month is usually less than the first month of GPU rental plus the evening spent on setup.sh.

Lower-VRAM Alternatives

Community ComfyUI workflows with quantized weights can run below the official minimum. They are genuinely useful for experimentation, but expect quality trade-offs and a slower pipeline. They also sit outside the official support path. Worth knowing before you rely on them for client work.

What Trellis 2 Generates

The reason any of this matters is output quality. TRELLIS.2's O-Voxel representation handles shapes that older methods flatten or break:

• Open surfaces: cloth, leaves, capes
• Non-manifold geometry: where several surfaces meet at one edge
• Internal cavities: hollow vessels, enclosed structures

Textures go beyond color. Base color, roughness, metallic, and opacity are generated per surface, which is what makes the result usable in a real-time engine rather than just a pretty render.

Commercial Use Rights

Can you use Trellis 2 commercially? Yes. MIT covers both the software and the outputs. Self-hosted generations and platform generations are both clear for commercial projects, and neither requires a separate license from Microsoft or from us.

Three practical notes:

1. Wrapper platforms add their own terms. MIT covers the model. A site reselling access may layer on its own usage restrictions — read before you pay.
2. Standard IP law still applies. Generating a 3D model of a copyrighted character does not grant you rights to that character, regardless of the license.
3. Rendering dependencies ship under their own licenses. The official repo bundles NVIDIA's nvdiffrast and nvdiffrec for PBR rendering. Normal use is fine; redistributing the toolchain requires reading those licenses.

FAQ

Is Trellis 2 free?

The model is — MIT license, download and run it yourself, including commercially. The official Trellis2.app platform is a paid cloud service starting at $19/month.

Is Trellis2.app the official platform?

Yes. We publish Trellis2.app's pricing, benchmarks, and documentation directly. Other sites offer access to the same model under their own brands and credit systems.

Can I try Trellis 2 for free online?

Community demos and Hugging Face Spaces come and go, so we don't link to a specific one. If a free demo is what you want, check that it runs TRELLIS.2 rather than TRELLIS 1, one quick test is a thin, open surface such as leaves or cloth, which TRELLIS 1 tends to flatten.

Do I need a GPU to use Trellis 2?

Not on the platform — generation runs in your browser. For local installation, the official minimum is 24GB of NVIDIA GPU memory.

What is the maximum resolution?

1536³ voxels with full PBR materials (base color, metallic, roughness, opacity).

Can I sell assets generated with Trellis 2?

Yes. MIT covers commercial use of self-hosted and platform outputs. Input images are still subject to ordinary IP rules.

How do platform credits work?

Credits reset monthly with your plan: Starter 15, Pro 50, Business 120. Consumption scales with output resolution. See the pricing page for the current breakdown.

Does the model work on Macs or AMD GPUs?

The official repository targets Linux with NVIDIA CUDA. Community ports and ComfyUI workflows sometimes support other setups, without official guarantees.

Get Started

• Already have a 24GB NVIDIA GPU? Clone microsoft/TRELLIS.2, pull the 4B checkpoint from Hugging Face, and run it locally, free forever.
• Want a result this afternoon? Start on the official platform — browser, no setup, from $19/month.
