Frequently asked questions
Can TiRex be used in a commercial project?
Yes. License: TiRex-2: Apache 2.0; first version: NXAI Community License. It allows commercial use, but it is still worth having a lawyer review the license before launch.
What hardware does TiRex need?
At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Some versions also run on an ordinary CPU, without a GPU. You can calculate the exact VRAM for your model size and context in the hardware calculator.
Does TiRex support Russian?
Language does not matter for this model: it does not work with text.

The TiRex weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
