How to run it

On your own serverWeights are downloaded from Hugging Face and served with vLLM (load and API) or llama.cpp (modest hardware). The model then runs in a closed network with no per-request fees.Hugging Face

I can set this up end to end: pick the model size, deploy it on your server and connect it to your systems. Quantization compresses a model so it takes less video memory and runs on more modest hardware. Answers change slightly, so quality is checked on your own examples.

Frequently asked questions

Can Jais be used in a commercial project?

Yes. License: Apache 2.0 (Jais 2: by access request on Hugging Face). It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does Jais 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 Jais support Russian?

No. The model card lists its languages and Russian is not among them.

Where can I download Jais and what does it cost?

The Jais 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.
