+🔥<span style="color: #ff3860">[HOT]</span> SeaLLMs project now has a dedicated website - [damo-nlp-sg.github.io/SeaLLMs](https://damo-nlp-sg.github.io/SeaLLMs/)
+
+We introduce [SeaLLM-7B-v2.5](https://huggingface.co/SeaLLMs/SeaLLM-7B-v2.5), the state-of-the-art multilingual LLM for Southeast Asian (SEA) languages 🇬🇧 🇨🇳 🇻🇳 🇮🇩 🇹🇭 🇲🇾 🇰🇭 🇱🇦 🇲🇲 🇵🇭. It is the most significant upgrade since [SeaLLM-13B](https://huggingface.co/SeaLLMs/SeaLLM-13B-Chat), with half the size, outperforming performance across diverse multilingual tasks, from world knowledge, math reasoning, instruction following, etc.
+
+### Highlights
+* [SeaLLM-7B-v2.5](https://huggingface.co/SeaLLMs/SeaLLM-7B-v2.5) outperforms GPT-3.5 and achieves 7B SOTA on most multilingual knowledge benchmarks for SEA languages (MMLU, M3Exam & VMLU).
+* It achieves 79.0 and 34.9 on GSM8K and MATH, surpassing GPT-3.5 in MATH.

+### What's new since SeaLLM-7B-v2?
+
+* SeaLLM-7B-v2.5 was built on top of Gemma-7b, and underwent large scale SFT and carefully designed alignment.
+
+
+## Evaluation
+
+
+### Multilingual World Knowledge
+
+
+We evaluate models on 3 benchmarks following the recommended default setups: 5-shot MMLU for En, 3-shot [M3Exam](https://arxiv.org/pdf/2306.05179.pdf) (M3e) for En, Zh, Vi, Id, Th, and zero-shot [VMLU](https://vmlu.ai/) for Vi.

+### Zero-shot CoT Multilingual Math Reasoning
+
+<!--
+[SeaLLM-7B-v2](https://huggingface.co/SeaLLMs/SeaLLM-7B-v2) achieves with **78.5** score on the GSM8K with zero-shot CoT reasoning, making it the **state of the art** in the realm of 7B models. It also outperforms GPT-3.5 in the same GSM8K benchmark as translated into SEA languages (🇨🇳 🇻🇳 🇮🇩 🇹🇭). [SeaLLM-7B-v2](https://huggingface.co/SeaLLMs/SeaLLM-7B-v2) also surpasses GPT-3.5 on the Thai-translated MATH benchmark, with **28.4** vs 18.1 scores.

+### Sea-Bench

+
+
+### Usage
+
+**IMPORTANT NOTICE for using the model**
+
+* `<bos>` must be at start of prompt, ff your code's tokenizer does not prepend `<bos>` by default, you MUST prepend <bos> into the prompt yourself, otherwise, it would not work!
+* Repitition penalty (e.g: in llama.cpp, ollama, LM-studio) must be set to **1** , otherwise will lead to degeneration!
+
+#### Instruction format
+
+```python
+# ! WARNING, if your code's tokenizer does not prepend <bos> by default,
+# You MUST prepend <bos> into the prompt yourself, otherwise, it would not work!
+prompt = """<|im_start|>system
+You are a helpful assistant.<eos>
+<|im_start|>user
+Hello world<eos>
+<|im_start|>assistant
+Hi there, how can I help?<eos>"""
+# <|im_start|> is not a special token.
+# Transformers chat_template should be consistent with vLLM format below.
+# ! ENSURE 1 and only 1 bos `<bos>` at the beginning of sequence
+print(tokenizer.convert_ids_to_tokens(tokenizer.encode(prompt)))
+"""
+```
+
+#### Using transformers's chat_template
+Install the latest transformers (>4.40)
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+device = "cuda" # the device to load the model onto
+# use bfloat16 to ensure the best performance.
+model = AutoModelForCausalLM.from_pretrained("SeaLLMs/SeaLLM-7B-v2.5", torch_dtype=torch.bfloat16, device_map=device)
+tokenizer = AutoTokenizer.from_pretrained("SeaLLMs/SeaLLM-7B-v2.5")
+messages = [
+    {"role": "system", "content": "You are a helpful assistant."},
+    {"role": "user", "content": "Hello world"},
+    {"role": "assistant", "content": "Hi there, how can I help you today?"},
+    {"role": "user", "content": "Explain general relativity in details."}
+]
+encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt", add_generation_prompt=True)
+print(tokenizer.convert_ids_to_tokens(encodeds[0]))
+model_inputs = encodeds.to(device)
+model.to(device)
+
+generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True, pad_token_id=tokenizer.pad_token_id)
+decoded = tokenizer.batch_decode(generated_ids)
+print(decoded[0])
+```
+#### Using vLLM
+```python
+from vllm import LLM, SamplingParams
+TURN_TEMPLATE = "<|im_start|>{role}\n{content}<eos>\n"
+TURN_PREFIX = "<|im_start|>{role}\n"
+def seallm_chat_convo_format(conversations, add_assistant_prefix: bool, system_prompt=None):
+    # conversations: list of dict with key `role` and `content` (openai format)
+    if conversations[0]['role'] != 'system' and system_prompt is not None:
+        conversations = [{"role": "system", "content": system_prompt}] + conversations
+    text = ''
+    for turn_id, turn in enumerate(conversations):
+        prompt = TURN_TEMPLATE.format(role=turn['role'], content=turn['content'])
+        text += prompt
+    if add_assistant_prefix:
+        prompt = TURN_PREFIX.format(role='assistant')
+        text += prompt    
+    return text
+sparams = SamplingParams(temperature=0.1, max_tokens=1024, stop=['<eos>', '<|im_start|>'])
+llm = LLM("SeaLLMs/SeaLLM-7B-v2.5", dtype="bfloat16")
+
+message = "Explain general relativity in details."
+prompt = seallm_chat_convo_format(message, True)
+gen = llm.generate(prompt, sampling_params)
+
+print(gen[0].outputs[0].text)
+```
+#### Fine-tuning SeaLLM-7B-v2.5
+Should follow the chat format and accurately mask out source tokens. Here is an example.
+```python
+conversations = [
+    {"role": "system", "content": "You are helful assistant."},
+    {"role": "user", "content": "Hello world."},
+    {"role": "assistant", "content": "Hi there, how can I help?"},
+    {"role": "user", "content": "Tell me a joke."},
+    {"role": "assistant", "content": "Why don't scientists trust atoms? Because they make up everything."},
+]
+def seallm_7b_v25_tokenize_multi_turns(tokenizer, conversations, add_assistant_prefix=False):
+    """
+    Inputs:

+            "token_type_ids": 1 if train and 0 if masked out (not train)
+        }
+    During training, need to create a labels, with masked-out tokens = -100 to avoid loss computations.
