Bielik 11B V2

🚀 Bielik-11B-v2

Bielik-11B-v2 is a generative text model with 11 billion parameters. It is initialized from Mistral-7B-v0.2 and trained on Polish text corpora, enabling it to understand and process the Polish language accurately.

🚀 Quick Start

This model can be easily loaded using the AutoModelForCausalLM functionality.

Basic Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

model_name = "speakleash/Bielik-11B-v2"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

Advanced Usage

In order to reduce the memory usage, you can use smaller precision (bfloat16).

import torch

model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16)

And then you can use HuggingFace Pipelines to generate text:

import transformers

text = "Najważniejszym celem człowieka na ziemi jest"

pipeline = transformers.pipeline("text-generation", model=model, tokenizer=tokenizer)
sequences = pipeline(max_new_tokens=100, do_sample=True, top_k=50, eos_token_id=tokenizer.eos_token_id, text_inputs=text)
for seq in sequences:
    print(f"Result: {seq['generated_text']}")

Generated output:

Najważniejszym celem człowieka na ziemi jest życie w pokoju, harmonii i miłości. Dla każdego z nas bardzo ważne jest, aby otaczać się kochanymi osobami.

📚 Documentation

Model

Bielik-11B-v2 has been trained with Megatron-LM using different parallelization techniques.

The model training was conducted on the Helios Supercomputer at the ACK Cyfronet AGH, utilizing 256 NVidia GH200 cards.

The training dataset was composed of Polish texts collected and made available through the SpeakLeash project, as well as a subset of CommonCrawl data. We used 200 billion tokens (over 700 GB of plain text) for two epochs of training.

Model description:

Quality evaluation

An XGBoost classification model was prepared and created to evaluate the quality of texts in native Polish language. It is based on 93 features, such as the ratio of out-of-vocabulary words to all words (OOVs), the number of nouns, verbs, average sentence length etc. The model outputs the category of a given document (either HIGH, MEDIUM or LOW) along with the probability. This approach allows implementation of a dedicated pipeline to choose documents, from which we've used entries with HIGH quality index and probability exceeding 90%.

This filtration and appropriate selection of texts enable the provision of a condensed and high-quality database of texts in Polish for training purposes.

Evaluation

Models have been evaluated on two leaderboards: Open PL LLM Leaderboard and Open LLM Leaderboard. The Open PL LLM Leaderboard uses a 5-shot evaluation and focuses on NLP tasks in Polish, while the Open LLM Leaderboard evaluates models on various English language tasks.

Open PL LLM Leaderboard

The benchmark evaluates models in NLP tasks like sentiment analysis, categorization, text classification but does not test chatting skills. Average column is an average score among all tasks normalized by baseline scores.

The results from the Open PL LLM Leaderboard show that the Bielik-11B-v2 model, with 11 billion parameters, achieved an average score of 58.14. This makes it the best performing model among those under 20B parameters, outperforming the second-best model in this category by an impressive 8.75 percentage points. This significant lead not only places it ahead of its predecessor, the Bielik-7B-v0.1 (which scored 34.34), but also demonstrates its superiority over other larger models. The substantial improvement highlights the remarkable advancements and optimizations made in this newer version.

Other Polish models listed include Qra-13b and Qra-7b, scoring 33.90 and 16.60 respectively, indicating that Bielik-11B-v2 outperforms these models by a considerable margin.

Additionally, the Bielik-11B-v2 was initialized from the weights of Mistral-7B-v0.2, which itself scored 38.81, further demonstrating the effective enhancements incorporated into the Bielik-11B-v2 model.

Open LLM Leaderboard

The Open LLM Leaderboard evaluates models on various English language tasks, providing insights into the model's performance across different linguistic challenges.

The results from the Open LLM Leaderboard demonstrate the impressive performance of Bielik-11B-v2 across various NLP tasks. With an average score of 65.87, it significantly outperforms its predecessor, Bielik-7B-v0.1, and even surpasses Mistral-7B-v0.2, which served as its initial weight basis.

Key observations:

1. Bielik-11B-v2 shows substantial improvements in most categories compared to Bielik-7B-v0.1, highlighting the effectiveness of the model's enhancements.
2. It performs exceptionally well in tasks like hellaswag (common sense reasoning), winogrande (commonsense reasoning), and gsm8k (mathematical problem-solving), indicating its versatility across different types of language understanding and generation tasks.
3. While Mistral-7B-v0.2 outperforms in truthfulqa_mc2, Bielik-11B-v2 maintains competitive performance in this truth-discernment task.

Although Bielik-11B-v2 was primarily trained on Polish data, it has retained and even improved its ability to understand and operate in English, as evidenced by its strong performance across these English-language benchmarks. This suggests that the model has effectively leveraged cross-lingual transfer learning, maintaining its Polish language expertise while enhancing its English language capabilities.

Limitations and Biases

⚠️ Important Note

Bielik-11B-v2 is not intended for deployment without fine-tuning. It should not be used for human-facing interactions without further guardrails and user consent.

⚠️ Important Note

Bielik-11B-v2 can produce factually incorrect output, and should not be relied on to produce factually accurate data. Bielik-11B-v2 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.
