## SeaLLM-chat-7B

This a **7B Chat** version of SeaLLMs. It Vietnamese 🇻🇳, Indonesian 🇮🇩, Thai 🇹🇭, Malay 🇲🇾, Khmer 🇰🇭, Lao 🇱🇦, Tagalog 🇵🇭 and Burmese 🇲🇲. 
It may have lower capability than the 13B models but it is much more memory-efficient and faster.

## How to Run:

SeaLLM models work the same way as Llama-2, so the Llama-2 generation codebase should be sufficient to run. 
However, as this is a chat model, you should wrap the prompt/instruction using the following format function.

You should also turn off add_special_tokens with `tokenizer.add_special_tokens = False`.

```python

BOS_TOKEN = '<s>'
EOS_TOKEN = '</s>'

B_INST, E_INST = "[INST]", "[/INST]"
B_SYS, E_SYS = "<<SYS>>\n", "\n<</SYS>>\n\n"

SYSTEM_PROMPT = """You are a multilingual, helpful, respectful and honest assistant. \
Please always answer as helpfully as possible, while being safe. Your \
answers should not include any harmful, unethical, racist, sexist, toxic, dangerous, or illegal content. Please ensure \
that your responses are socially unbiased and positive in nature.

If a question does not make any sense, or is not factually coherent, explain why instead of answering something not \
correct. If you don't know the answer to a question, please don't share false information.

As a multilingual assistant, you must respond and follow instructions in the native language of the user by default, unless told otherwise. \
Your response should adapt to the norms and customs of the respective language and culture.
"""


def chat_multiturn_seq_format(
    message: str,
    history: List[Tuple[str, str]] = None, 
):
    """
    ```
        <bos>[INST] B_SYS SytemPrompt E_SYS Prompt [/INST] Answer <eos>
        <bos>[INST] Prompt [/INST] Answer <eos>
        <bos>[INST] Prompt [/INST]
    ```
    As the format auto-add <bos>, please turn off add_special_tokens with `tokenizer.add_special_tokens = False`
    Inputs:
      message: the current prompt
      history: list of list indicating previous conversation. [[message1, response1], [message2, response2]]
    Outputs:
      full_prompt: the prompt that should go into the chat model

    e.g:
      full_prompt = chat_multiturn_seq_format("Hello world")
      output = model.generate(tokenizer.encode(full_prompt, add_special_tokens=False), ...)
    """
    text = ''
    for i, (prompt, res) in enumerate(history):
        if i == 0:
            text += f"{bos_token}{B_INST} {B_SYS} {sys_prompt} {E_SYS} {prompt} {E_INST}"
        else:
            text += f"{bos_token}{B_INST} {prompt}{end_instr}"
        if res is not None:
            text += f" {res} {eos_token} "
    if len(history) == 0 or text.strip() == '':
        text = f"{bos_token}{B_INST} {B_SYS} {sys_prompt} {E_SYS} {message} {E_INST}"
    else:
        text += f"{bos_token}{B_INST} {message} {E_INST}"
    return text
