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.

Frequently asked questions

Can SERA (Ai2 Open Coding Agents) be used in a commercial project?

Yes. License: Apache 2.0. It allows commercial use, but it is still worth having a lawyer review the license before launch.

What hardware does SERA (Ai2 Open Coding Agents) need?

At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.

Does SERA (Ai2 Open Coding Agents) support Russian?

The model card does not list languages, so Russian support cannot be promised — it has to be tested on your own examples.

Where can I download SERA (Ai2 Open Coding Agents) and what does it cost?

The SERA (Ai2 Open Coding Agents) 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.
