+ # **Bellatrix-Tiny-1.5B-R1**
15
+
16
+ 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).
17
+
18
+ # **Use with transformers**
19
+
20
+ 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.
21
+
22
+ Make sure to update your transformers installation via `pip install --upgrade transformers`.
23
+
24
+ ```python
25
+ import torch
26
+ from transformers import pipeline
27
+
28
+ model_id = "prithivMLmods/Bellatrix-Tiny-1.5B-R1"
29
+ pipe = pipeline(
30
+ "text-generation",
31
+ model=model_id,
32
+ torch_dtype=torch.bfloat16,
33
+ device_map="auto",
34
+ )
35
+ messages = [
36
+ {"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"},
37
+ {"role": "user", "content": "Who are you?"},
38
+ ]
39
+ outputs = pipe(
40
+ messages,
41
+ max_new_tokens=256,
42
+ )
43
+ print(outputs[0]["generated_text"][-1])
44
+ ```
45
+
46
+ 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)

48
+ # **Intended Use**
49
+ Bellatrix is designed for applications that require advanced reasoning and multilingual dialogue capabilities. It is particularly suitable for:
50
+ - **Agentic Retrieval**: Enabling intelligent retrieval of relevant information in a dialogue or query-response system.
51
+ - **Summarization Tasks**: Condensing large bodies of text into concise summaries for easier comprehension.
52
+ - **Multilingual Use Cases**: Supporting conversations in multiple languages with high accuracy and coherence.
53
+ - **Instruction-Based Applications**: Following complex, context-aware instructions to generate precise outputs in a variety of scenarios.
54
+
55
+ # **Limitations**
56
+ Despite its capabilities, Bellatrix has some limitations:
57
+ 1. **Domain Specificity**: While it performs well on general tasks, its performance may degrade with highly specialized or niche datasets.
58
+ 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.
59
+ 3. **Computational Resources**: The model’s optimized transformer architecture can be resource-intensive, requiring significant computational power for fine-tuning and inference.
60
+ 4. **Language Coverage**: While multilingual, some languages or dialects may have limited support or lower performance compared to widely used ones.
61
+ 5. **Real-World Contexts**: It may struggle with understanding nuanced or ambiguous real-world scenarios not covered during training.
