What is Bielik?
Bielik is a family of open language models developed by the non-profit SpeakLeash Foundation together with partners and a community, with a focus on Polish language and culture. The models range from small ones for specific tasks to larger ones for natural conversation, and they are designed to run locally so that organizations can keep sensitive data under their own control.
You can try Bielik for free in the public chat at chat.bielik.ai, install the model on your own hardware (the site points to LM Studio and Hugging Face for this), or join the community. The page also lists related projects: Bielik Guard, a toolset for secure and ethical AI interactions, Bielik Squadron for learning AI agents, Citizen Bielik for teaching the model European and local heritage, and Bielik Nest Builders workshops on building AI agents.
