## Usage    

> Simple Usage
```python
from transllm import LLMtranslator

open_llama3b_kor = LLMtranslator('openlm-research/open_llama_3b', target_lang='ko', translator='google') # Korean

trnaslated_answer = open_llama3b_kor.generate("나와 내 동년배들이 좋아하는 뉴진스에 대해서 알려줘")
print(trnaslated_answer)
```
<br>

> Official Google Translation API
- Support Languages: https://cloud.google.com/translate/docs/languages?hl=ko
> Unofficial Google Trnaslator for non-profit purposes (such as feature testing)

```python
from transllm import LLMtranslator

# Set huggingface repository
model_path = 'openlm-research/open_llama_3b'
# model_path = 'openlm-research/open_llama_7b'
# model_path = 'openlm-research/open_llama_13b'

# Get TransLLM Object (Korean)
# open_llama3b_kor = LLMtranslator(model_path, target_lang='ko', translator='google_official', google_api_key='xxxxxx') # Official Google Cloud Translation API 
open_llama3b_kor = LLMtranslator(model_path, target_lang='ko', translator='google') # Unofficial test



# Using Prompt in multi-language
prompt = "나와 내 동년배들이 좋아하는 뉴진스에 대해서 알려줘"
trnaslated_answer = open_llama3b_kor.generate(prompt)
print(trnaslated_answer)
```

<br>

> DeepL, Open AI, Bard
- Support Languages: https://www.deepl.com/pro/select-country?cta=header-pro-button/#developer

Open AI, Bard use pre-prompt for translation.
```python
from transllm import LLMtranslator

# Set huggingface repository
model_path = 'openlm-research/open_llama_3b'
# model_path = 'openlm-research/open_llama_7b'
# model_path = 'openlm-research/open_llama_13b'

# Choose Translate Service API: DeepL, OpenAI, Bard
open_llama3b_kor = LLMtranslator(model_path, target_lang='ES', translator='deepl', deepl_api='xxxxxxx') # Language == Spanish
# open_llama3b_kor = LLMtranslator(model_path, target_lang='korean', translator='openai', openai_api='xxxxxxx', openai_model='gpt-3.5-turbo')
# open_llama3b_kor = LLMtranslator(model_path, target_lang='korean', translator='bard', bard_api='xxxxxxx')

# Using Prompt in multi-language
prompt = "나와 내 동년배들이 좋아하는 뉴진스에 대해서 알려줘"
trnaslated_answer = open_llama3b_kor.generate(prompt)
print(trnaslated_answer)
```

## Customized Inference
Applying LLMs to the majority of Hugging Face repositories is generally feasible. However, it can be challenging to apply them to objects that require unique tokenizers or inference processes. In such cases, it is recommended to customize the usage by incorporating a translation module for prompts.

In other words, if you are familiar with the inference process or code from Hugging Face repositories, you can customize the translation object by adding a translation module before and after the known inference process or code. Check [translang repository](https://github.com/dsdanielpark/translang) for more details.
```python
import torch
from trnasllm import LLMtranslator


class MyLLMtranslator(LLMtranslator):
    def __init__(
        self,
        model_path,
        target_lang="ko",
        translator="google",
        torch_dtype=torch.float16,
        device_map="auto",
        deepl_api=None,
        bard_api=None,
        openai_model="gpt-3.5-turbo",
        openai_api=None
    ):
        super().__init__(
            model_path=model_path,
            target_lang=target_lang,
            translator=translator,
            torch_dtype=torch_dtype,
            device_map=device_map,
            deepl_api=deepl_api,
            bard_api=bard_api,
            openai_model=openai_model,
            openai_api=openai_api
        )

    def inference(self, prompt: str) -> str:
        # Custom logic for inference
        # You can override the implementation of the inference method here
        # and provide your own logic for generating the translated answer
        # Remember to return the translated answer as a string.

        answer = customizing_process(prompt)
        # Custom inference logic...
        
        return answer
```
