# **Bellatrix-Tiny-1.5B-R1**
|
|
|
|
|
|
Bellatrix is based on a reasoning-based model designed for the DeepSeek-R1 synthetic dataset entries. The pipeline's instruction-tuned, text-only models are optimized for multilingual dialogue use cases, including agentic retrieval and summarization tasks. These models outperform many of the available open-source options. Bellatrix is an auto-regressive language model that uses an optimized transformer architecture. The tuned versions utilize supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF).
|
|
|
|
|
|
# **Use with transformers**
|
|
|
|
|
|
Starting with `transformers >= 4.43.0` onward, you can run conversational inference using the Transformers `pipeline` abstraction or by leveraging the Auto classes with the `generate()` function.
|
|
|
|
|
|
Make sure to update your transformers installation via `pip install --upgrade transformers`.
|
|
|
|
|
|
```python
|
|
|
import torch
|
|
|
from transformers import pipeline
|
|
|
|
|
|
model_id = "prithivMLmods/Bellatrix-Tiny-1.5B-R1"
|
|
|
pipe = pipeline(
|
|
|
"text-generation",
|
|
|
model=model_id,
|
|
|
torch_dtype=torch.bfloat16,
|
|
|
device_map="auto",
|
|
|
)
|
|
|
messages = [
|
|
|
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
|
|
|
{"role": "user", "content": "Who are you?"},
|
|
|
]
|
|
|
outputs = pipe(
|
|
|
messages,
|
|
|
max_new_tokens=256,
|
|
|
)
|
|
|
print(outputs[0]["generated_text"][-1])
|
|
|
```
|
|
|
|
|
|
Note: You can also find detailed recipes on how to use the model locally, with `torch.compile()`, assisted generations, quantized and more at [`huggingface-llama-recipes`](https://github.com/huggingface/huggingface-llama-recipes)

|
# **Intended Use**
|
|
|
Bellatrix is designed for applications that require advanced reasoning and multilingual dialogue capabilities. It is particularly suitable for:
|
|
|
- **Agentic Retrieval**: Enabling intelligent retrieval of relevant information in a dialogue or query-response system.
|
|
|
- **Summarization Tasks**: Condensing large bodies of text into concise summaries for easier comprehension.
|
|
|
- **Multilingual Use Cases**: Supporting conversations in multiple languages with high accuracy and coherence.
|
|
|
- **Instruction-Based Applications**: Following complex, context-aware instructions to generate precise outputs in a variety of scenarios.
|
|
|
|
|
|
# **Limitations**
|
|
|
Despite its capabilities, Bellatrix has some limitations:
|
|
|
1. **Domain Specificity**: While it performs well on general tasks, its performance may degrade with highly specialized or niche datasets.
|
|
|
2. **Dependence on Training Data**: It is only as good as the quality and diversity of its training data, which may lead to biases or inaccuracies.
|
|
|
3. **Computational Resources**: The model’s optimized transformer architecture can be resource-intensive, requiring significant computational power for fine-tuning and inference.
|
|
|
4. **Language Coverage**: While multilingual, some languages or dialects may have limited support or lower performance compared to widely used ones.
|
|
|
5. **Real-World Contexts**: It may struggle with understanding nuanced or ambiguous real-world scenarios not covered during training. |
