# Llama3 8B CPT Sahabat-AI v1

**Sahabat-AI** (Indonesian language for “close friends”) is a collection of Large Language Models (LLMs) which has been pretrained and instruct-tuned for Indonesian language and its various dialects. 
Sahabat-AI ecosystem is co-initiated by Indonesian tech and telecommunication companies:  GoTo Group and Indosat Ooredoo Hutchison.

This is the card for the Llama3 8B CPT Sahabat-AI v1 base model which has undergone continued pre-training from the [AI Singapore-Llama-3-8B-Sea-Lion v2.1-Instruct](https://huggingface.co/aisingapore/llama3-8b-cpt-sea-lionv2.1-instruct) model.

## Model Details

### Model Description

The continued pre-training data for Llama3 8B CPT Sahabat-AI v1 base model encompasses approximately 50B tokens.

- **Co-initiated by:**  PT GoTo Gojek Tokopedia Tbk, Indosat Ooredoo Hutchison
- **Developed by:** PT GoTo Gojek Tokopedia Tbk,  AI Singapore
- **Model type:** Decoder
- **Languages:** English, Indonesian, Javanese, Sundanese
- **License:** [Llama3 Community License](https://huggingface.co/meta-llama/Meta-Llama-3-8B/blob/main/LICENSE)

For tokenisation, the model employs the default tokenizer used in Llama-3-8B. The model has a context length of 8192.

### Benchmark Performance
We evaluated Llama 8B CPT Sahabat-AI v1 base model on general language capabilities.

#### General Language Capabilities
For the evaluation of general language capabilities, we employed the 
- [SEA HELM (also known as BHASA) evaluation benchmark](https://arxiv.org/abs/2309.06085v2) across a variety of tasks.
  - These tasks include Question Answering (QA), Sentiment Analysis (Sentiment), Toxicity Detection (Toxicity), Translation in both directions (Eng>Lang & Lang>Eng), Abstractive Summarization (Summ), Causal Reasoning (Causal) and Natural Language Inference (NLI).
  - We also added support for Javanese and Sundanese for the BHASA tasks whenever applicable
- and the common English tasks from the [HuggingFace LLM Leaderboard](https://huggingface.co/spaces/open-llm-leaderboard/open_llm_leaderboard).
  - These tasks consist of [IFEval, BBH, Math Lvl 5, GPQA, MuSR, and MMLU-PRO.](https://huggingface.co/docs/leaderboards/open_llm_leaderboard/about)
  - **Caveat**: Our results differ from the HuggingFace LLM Leaderboard because we have used [VLLM](https://docs.vllm.ai/en/latest/) as our inference platform. VLLM caps the context size at **4096 tokens** while HuggingFace was set to **8192 tokens**.

Note: SEA HELM is implemented using prompts to elicit answers in a strict format. For all tasks, the model is expected to provide an answer tag from which the answer is automatically extracted. For tasks where options are provided, the answer should comprise one of the pre-defined options. The scores for each task is normalised to account for baseline performance due to random chance.

The evaluation was done **five-shot** with native prompts on a sample of 100-1000 instances for each dataset.

## Call for Collaboration 

Sahabat-AI (Indonesian language for “close friends”) a **local open source Large Language Model (LLM) ecosystem in Indonesian language**, co-initiated by Indonesian tech and telecommunication companies:  GoTo Group and Indosat Ooredoo Hutchison. 
Sahabat-AI ecosystem aims to empower Indonesians who want to develop AI-based services and applications using Bahasa Indonesia and its various local dialects. 

We are supported by research centers and global tech experts such as AI Singapore and Tech Mahendra to train the model to gain general language understanding.

We also collaborate with key top Indonesia universities such as University of Indonesia, Gadjah Mada University, Bogor Institute of Agriculture, Bandung Institute of Technology, including top Indonesia media groups, such as Kompas Gramedia Group and Republika to train and enrich the model in Bahasa Indonesia, ensuring optimum provision of local context and cultural relevance.

We would like to invite **researchers, developers, and language enthusiasts** to actively contribute to the enhancement and expansion of Sahabat-AI. 
Your collaborations can involve:
- Identifying and reporting technical issues
- Sharing pre-training, instruction, and preference data
- Improving documentation usability
- Proposing and implementing new model evaluation tasks and metrics 

Join us in shaping the future of Sahabat-AI by sharing your expertise and insights to make these models more accessible, accurate, and versatile.

You can contribute your ideas through [this form.](https://docs.google.com/forms/d/1_us969eQtEooYOn4XkvGkdP5VHOyCbO6L_sd9kTMnaA/edit)
