Bielik-PL-11B-v3.0-Instruct is a generative text model featuring 11 billion parameters. It is an instruct fine-tuned version of the Bielik-11B-v3-Base-20250730 after replacing its tokenizer to the APT4 tokenizer optimized specifically for the Polish language. Forementioned model stands as a testament to the unique collaboration between the open-science/open-source project SpeakLeash and the High Performance Computing (HPC) center: ACK Cyfronet AGH. Developed and trained on multilingual text corpora across 32 European languages, with emphasis on Polish, which has been cherry-picked and processed by the SpeakLeash team, this endeavor leverages Polish large-scale computing infrastructure, specifically within the PLGrid environment, and more precisely, the HPC centers: ACK Cyfronet AGH. The creation and training of the Bielik-PL-11B-v3.0-Instruct was propelled by the support of computational grant number PLG/2024/016951, conducted on the Athena and Helios supercomputer, enabling the use of cutting-edge technology and computational resources essential for large-scale machine learning processes. As a result, the model exhibits an exceptional ability to understand and process the Polish language and other European languages, providing accurate responses and performing a variety of linguistic tasks with high precision.

🗣️ Chat: https://chat.bielik.ai/
The model is a successor to the Bielik v2 series, and its development also leveraged the knowledge and experience gained while working on the Bielik v3 Small models.
The SpeakLeash team is working on their own set of instructions in Polish, which is continuously being expanded and refined by annotators. A portion of these instructions, which had been manually verified and corrected, has been utilized for training purposes. Moreover, due to the limited availability of high-quality instructions in Polish, synthetic instructions were generated and used in training. The dataset used for training comprised over 20 million instructions, consisting of more than 17 billion tokens.
To align the model with user preferences we employed the DPO-Positive method, utilizing both generated and manually corrected examples, which were scored by a metamodel. A dataset comprising over 114,000 examples of varying lengths to address different aspects of response style. It was filtered and evaluated by the reward model to select instructions with the right level of difference between chosen and rejected. The novelty introduced in DPO-P was multi-turn conversations introduction.
In the final stage of the alignment pipeline, Reinforcement Learning (RL) was used to further enhance the model's analytical capabilities. Training employed Group Relative Policy Optimization (GRPO) and its variant, Dr. GRPO, which was chosen to improve token efficiency by reducing the tendency of models to artificially increase response length to maximize rewards. The RL training was conducted using the Volcano Engine Reinforcement Learning (VERL) framework, providing a scalable and modular training environment. The training corpus comprised 143k curated problems spanning logic, STEM, mathematics, and tool-use domains, with all samples selected based on the availability of Reinforcement Learning from Verifiable Rewards (RLVR), ensuring that each problem had a definitive, verifiable solution.
Bielik instruct models have been trained with the use of an original open source framework called ALLaMo implemented by Krzysztof Ociepa. This framework allows users to train language models with architecture similar to LLaMA and Mistral in fast and efficient way.
Bielik-PL-11B-v3.0-Instruct uses ChatML as the prompt format.
E.g.
text
prompt = "<s><|im_start|> user\nJakie mamy pory roku?<|im_end|> \n<|im_start|> assistant\n"completion = "W Polsce mamy 4 pory roku: wiosna, lato, jesień i zima.<|im_end|> \n"This format is available as a chat template via the apply_chat_template() method:
python
import torchfrom transformers import AutoModelForCausalLM, AutoTokenizer device = "cuda" # the device to load the model onto model_name = "speakleash/Bielik-PL-11B-v3.0-Instruct" tokenizer = AutoTokenizer.from_pretrained(model_name)model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16) messages = [ {"role": "system", "content": "Odpowiadaj krótko, precyzyjnie i wyłącznie w języku polskim."}, {"role": "user", "content": "Jakie mamy pory roku w Polsce?"}, {"role": "assistant", "content": "W Polsce mamy 4 pory roku: wiosna, lato, jesień i zima."}, {"role": "user", "content": "Która jest najcieplejsza?"}] input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt") model_inputs = input_ids.to(device)model.to(device) generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True)decoded = tokenizer.batch_decode(generated_ids)print(decoded[0])Fully formated input conversation by apply_chat_template from previous example:

It does not have any moderation mechanisms. We're looking forward to engaging with the community in ways to make the model respect guardrails, allowing for deployment in environments requiring moderated outputs.
Bielik-PL-11B-v3.0-Instruct can produce factually incorrect output, and should not be relied on to produce factually accurate data. Bielik-PL-11B-v3.0-Instruct was trained on various public datasets. While great efforts have been taken to clear the training data, it is possible that this model can generate lewd, false, biased or otherwise offensive outputs.
The model could not have been created without the commitment and work of the entire SpeakLeash team, whose contribution is invaluable. Thanks to the hard work of many individuals, it was possible to gather a large amount of content in Polish and establish collaboration between the open-science SpeakLeash project and the HPC center: ACK Cyfronet AGH. Individuals who contributed to the creation of the model: Sebastian Kondracki, Marek Magryś, Igor Ciuciura, Paweł Kiszczak, Dominika Basaj, Kuba Sołtys, Karol Jezierski, Jan Sowa, Anna Przybył, Agnieszka Ratajska, Witold Wydmański.
We gratefully acknowledge Polish high-performance computing infrastructure PLGrid (HPC Center: ACK Cyfronet AGH) for providing computer facilities and support within computational grant no. PLG/2024/016951.
