# Saiga2 70B, Russian LLaMA2-based chatbot

Based on [LLaMA-2 70B fp16](https://huggingface.co/TheBloke/Llama-2-70B-fp16)

This is an adapter-only version.

Training code: [link](https://github.com/IlyaGusev/rulm/tree/master/self_instruct)

**WARNING**: Avoid using V100 (in Colab, for example). Outputs are much worse in this case.

```python
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig

MODEL_NAME = "IlyaGusev/saiga2_70b_lora"
DEFAULT_MESSAGE_TEMPLATE = "<s>{role}\n{content}</s>\n"
DEFAULT_SYSTEM_PROMPT = "Ты — Сайга, русскоязычный автоматический ассистент. Ты разговариваешь с людьми и помогаешь им."

class Conversation:

            message_text = self.message_template.format(**message)
            final_text += message_text

    output_ids = output_ids[len(data["input_ids"][0]):]
    output = tokenizer.decode(output_ids, skip_special_tokens=True)
    return output.strip()

for inp in inputs:
    conversation = Conversation()
    conversation.add_user_message(inp)

    output = generate(model, tokenizer, prompt, generation_config)
    print(inp)
    print(output)
    print()
    print("==============================")
    print()

Examples:
```
User: Почему трава зеленая? 
Saiga:

```
User: Сочини длинный рассказ, обязательно упоминая следующие объекты. Дано: Таня, мяч
