# **Bellatrix-Tiny-0.5B**
|
| 23 |
+
|
| 24 |
+
Bellatrix is based on a reasoning-based model designed for the QWQ 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).
|
| 25 |
+
|
| 26 |
+
# **Use with transformers**
|
| 27 |
+
|
| 28 |
+
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.
|
| 29 |
+
|
| 30 |
+
Make sure to update your transformers installation via `pip install --upgrade transformers`.
|
| 31 |
+
|
| 32 |
+
```python
|
| 33 |
+
import torch
|
| 34 |
+
from transformers import pipeline
|
| 35 |
+
|
| 36 |
+
model_id = "prithivMLmods/Bellatrix-Tiny-0.5B"
|
| 37 |
+
pipe = pipeline(
|
| 38 |
+
"text-generation",
|
| 39 |
+
model=model_id,
|
| 40 |
+
torch_dtype=torch.bfloat16,
|
| 41 |
+
device_map="auto",
|
| 42 |
+
)
|
| 43 |
+
messages = [
|
| 44 |
+
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
|
| 45 |
+
{"role": "user", "content": "Who are you?"},
|
| 46 |
+
]
|
| 47 |
+
outputs = pipe(
|
| 48 |
+
messages,
|
| 49 |
+
max_new_tokens=256,
|
| 50 |
+
)
|
| 51 |
+
print(outputs[0]["generated_text"][-1])
|
| 52 |
+
```
|
| 53 |
+
|
| 54 |
+
Note: You can also find detailed recipes on how to use the model locally, with `torch.compile()`, assisted generations, quantised and more at [`huggingface-llama-recipes`](https://github.com/huggingface/huggingface-llama-recipes)

# **Intended Use**
|
| 57 |
+
|
| 58 |
+
Bellatrix is designed for applications that require advanced reasoning and multilingual dialogue capabilities. It is particularly suitable for:
|
| 59 |
+
|
| 60 |
+
- **Agentic Retrieval**: Enabling intelligent retrieval of relevant information in a dialogue or query-response system.
|
| 61 |
+
- **Summarization Tasks**: Condensing large bodies of text into concise summaries for easier comprehension.
|
| 62 |
+
- **Multilingual Use Cases**: Supporting conversations in multiple languages with high accuracy and coherence.
|
| 63 |
+
- **Instruction-Based Applications**: Following complex, context-aware instructions to generate precise outputs in a variety of scenarios.
|
| 64 |
+
|
| 65 |
+
# **Limitations**
|
| 66 |
+
|
| 67 |
+
Despite its capabilities, Bellatrix has some limitations:
|
| 68 |
+
|
| 69 |
+
1. **Domain Specificity**: While it performs well on general tasks, its performance may degrade with highly specialized or niche datasets.
|
| 70 |
+
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.
|
| 71 |
+
3. **Computational Resources**: The model’s optimized transformer architecture can be resource-intensive, requiring significant computational power for fine-tuning and inference.
|
| 72 |
+
4. **Language Coverage**: While multilingual, some languages or dialects may have limited support or lower performance compared to widely used ones.
|
| 73 |
+
5. **Real-World Contexts**: It may struggle with understanding nuanced or ambiguous real-world scenarios not covered during training.
