|

SambaLingo-Bulgarian-Chat is a human aligned chat model trained in Bulgarian and English. It is trained using direct preference optimization on top the base model [SambaLingo-Bulgarian-Base](https://huggingface.co/sambanovasystems/SambaLingo-Bulgarian-Base). The base model adapts [Llama 2](https://huggingface.co/meta-llama/Llama-2-7b-hf) to Bulgarian by training on 63 billion tokens from the Bulgarian split of the [Cultura-X](https://huggingface.co/datasets/uonlp/CulturaX) dataset. Try this model at [SambaLingo-chat-space](https://huggingface.co/spaces/sambanovasystems/SambaLingo-chat-space).

|
||
|
||
## Getting Started
|
||
|
||
### Loading Model With Hugging Face
|
||
Please make sure to set use_fast=False when loading the tokenizer.
|
||
```python
|
||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||
|
||
tokenizer = AutoTokenizer.from_pretrained("sambanovasystems/SambaLingo-Bulgarian-Chat", use_fast=False)
|
||
model = AutoModelForCausalLM.from_pretrained("sambanovasystems/SambaLingo-Bulgarian-Chat", device_map="auto", torch_dtype="auto")
|
||
```
|
||
|
||
### Interacting With Model Pipeline
|
||
Please make sure to set use_fast=False when loading the tokenizer.
|
||
```python
|
||
from transformers import pipeline
|
||
pipe = pipeline("text-generation", model="sambanovasystems/SambaLingo-Bulgarian-Chat", device_map="auto", use_fast=False)
|
||
messages = [
|
||
{"role": "user", "content": {YOUR_QUESTION}},
|
||
]
|
||
prompt = pipe.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
|
||
outputs = pipe(prompt)[0]
|
||
outputs = outputs["generated_text"]
|
||
```
|
||
|
||
### Suggested Inference Parameters
|
||
- Temperature: 0.8
|
||
- Repetition penalty: 1.0
|
||
- Top-p: 0.9
|
||
|
||
### Prompting Guidelines
|
||
To prompt this model, please use the following chat template:
|
||
```
|
||
<|user|>\n{question}</s>\n<|assistant|>\n
|
||
```
|
||
|
||
### Example Prompts and Generations
|
||
```
|
||
<|user|>
|
||
Какъв извод можеш да извадиш за чувството, което изпитват героите от следната кратка история:
|
||
|
||
Мария чакаше с трепет да дойде 27-ми. Още само три дни и корабът щеше да акостира на пристанището. След 6 дълги месеца тя най-после щеше да види Иван. Когато денят най-после дойде, тя отиде на пристанището заедно с десетки други жени. Моряците един по един започнаха да слизат. Най-накрая тя съзря погледа на Иван, и двамата се прегърнаха силно.</s>
|
||
<|assistant|>
|
||
Мария изпитва силно чувство на очакване и нетърпение да види Иван след шестмесечна раздяла. Тя е развълнувана и щастлива да го види отново и прегръдката им показва, че и двамата са били много развълнувани да се съберат отново.
|
||
```
|
||
|
||
## Training Details
|
||
The alignment phase follows the recipe for [Zephyr-7B](https://huggingface.co/HuggingFaceH4/zephyr-7b-beta), and comprises two stages: supervised fine-tuning (SFT) and Direct Performance Optimization (DPO).
|
||
|
||
The SFT phase was done on the [ultrachat_200k](https://huggingface.co/datasets/HuggingFaceH4/ultrachat_200k) dataset mixed with the Google translated version of the ultrachat_200k dataset. It was trained for one epoch with global batch size 512 and max sequence length 2048 tokens. We used a linear decay learning rate of 2e-5 and 10% warmup.
|
||
|
||
The DPO phase was done on the [ultrafeedback](https://huggingface.co/datasets/HuggingFaceH4/ultrafeedback_binarized) dataset and [cai-conversation-harmless](https://huggingface.co/datasets/HuggingFaceH4/cai-conversation-harmless) dataset, mixed with 10% of the data Google translated. It was trained with global batch size 32 and for three epochs. We used a linear decay learning rate of 5e-7, 10% warmup and β=0.1 as the regularization factor for DPO.
|
||
|
||
|
||
## Tokenizer Details
|
||
We extended the vocabulary of the base llama model from 32,000 tokens to 57,000 tokens by adding up to 25,000 non-overlapping tokens from the new language.
|
||
|
||

## Uses
|
||
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
|
||
|
||
### Direct Use
|
||
|
||
<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
|
||
Use of this model is governed by the Meta’s [Llama 2 Community License Agreement](https://ai.meta.com/llama/license/). Please review and accept the license before downloading the model weights.

|
||
|
||
### Out-of-Scope Use
|
||
|
||
<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->
|
||
SambaLingo should NOT be used for:
|
||
|
||
- Mission-critical applications
|
||
- Applications that involve the safety of others
|
||
- Making highly important decisions
|
||
|
||
## Bias, Risks, and Limitations
|
||
|
||
<!-- This section is meant to convey both technical and sociotechnical limitations. -->
|
||
|
||
Like all LLMs, SambaLingo has certain limitations:
|
||
- Hallucination: Model may sometimes generate responses that contain plausible-sounding but factually incorrect or irrelevant information.
|
||
- Code Switching: The model might unintentionally switch between languages or dialects within a single response, affecting the coherence and understandability of the output.
|
||
- Repetition: The Model may produce repetitive phrases or sentences, leading to less engaging and informative responses.
|
||
- Coding and Math: The model's performance in generating accurate code or solving complex mathematical problems may be limited.
|
||
- Toxicity: The model could inadvertently generate responses containing inappropriate or harmful content.
|
||
