Bielikchat

Bielik Chat is the public chat interface for Bielik, a Polish open-source large language model developed by the SpeakLeash (Spichlerz) foundation — a community-driven initiative building a 1TB+ Polish-language dataset and generative AI models optimised for the Polish language.

Named after the Polish white-tailed eagle (bielik), the project is one of Europe's flagship efforts in sovereign AI — a locally-trained, Polish-optimised alternative to ChatGPT and Gemini that understands Polish grammar, idiom, and cultural context far better than general-purpose models fine-tuned primarily on English.

Key features:

• Polish-optimised tokenizer — trained specifically for Polish linguistic structure
• Open source — models, weights, and training data openly available
• Generative Pre-trained Transformer — modern LLM architecture
• Community-driven — developed openly via Discord and GitHub by Polish AI researchers
• Public chat arena — try Bielik and compare with other Polish-capable models
• Sovereign AI — trained and operated in Poland, independent from US hyperscalers

The SpeakLeash foundation partners with Polish academic institutions and continues to release new model versions with improved Polish performance. A free community project — ideal for Polish users, researchers, and developers needing an LLM that truly speaks Polish.
