Fundacja SpeakLeash

Bielik.ai is an open ecosystem of Polish-language large language models, built and maintained by the SpeakLeash Foundation with partners and a community of contributors. The models range from small 1.5B and 4.5B variants that run on modest hardware to the flagship 11B model, and the project publishes weights, model cards, technical papers and benchmark results.

The main model family is Bielik 11B v3, available as instruct and base versions in several formats including GGUF, FP8, AWQ and MLX. A compressed 7B version, Bielik-Minitron, and a set of small models for testing, edge devices and education sit alongside it. Bielik Guard, also called Sójka, is a family of safety classifiers for moderating Polish text.

The page says the models are meant to run locally, on your own equipment, on-premise or in isolated environments, so prompts and outputs do not have to leave your systems. It describes a Polish training corpus, a tokenizer tuned for Polish, and Polish benchmarks, which it says help the models handle declension and local terminology.

For people who want to try the model, the site links to a public chat in the browser. For developers, it gives an Ollama command and points to Hugging Face, llama.cpp, vLLM and transformers as other ways to run it. Contributors can join the Discord, work on GitHub, or take part in Bielik Arena, a community evaluation where people compare model answers in Polish.

The page describes its audience as companies building internal assistants and retrieval systems over documents, public administration bodies, and researchers and the wider community. It lists use cases such as retrieval over company documents, anonymising sensitive data, and government assistants.

The models are released under the Apache 2.0 licence, which the FAQ says allows commercial use, modification and redistribution without licence fees. The Bielik Arena, Data Dashboard and benchmarks such as the Open PL LLM Leaderboard are free to view.

The page does not list prices for any hosted service, so this listing does not state a starting price.
