# Gemma2 9B CPT Sahabat AI v1
Sahabat AI v1 is a collection of Large Language Models (LLMs) which has been pretrained and instruct-tuned for Indonesian languages.
This is the card for the Gemma2 9B CPT Sahabat AI v1 base model which has undergone continued pre-training from the base [Gemma2 9B CPT SEA-LIONv3 base](https://huggingface.co/aisingapore/gemma2-9b-cpt-sea-lionv3-base) model.
Sahabat is Indonesian for "Close Friends."
## Model Details
### Model Description
The continued pre-training data for Gemma2 9B CPT Sahabat AI v1 base model encompasses approximately 50B tokens.
- **Developed by:** PT GoTo Gojek Tokopedia Tbk, AI Singapore
- **Funded by:** PT GoTo Gojek Tokopedia Tbk, AI Singapore
- **Model type:** Decoder
- **Languages:** English, Indonesian, Javanese, Sundanese
- **License:** [Gemma Community License](https://ai.google.dev/gemma/terms)
For tokenisation, the model employs the default tokenizer used in Gemma-2-9B. The model has a context length of 8192.
### Benchmark Performance
We evaluated Gemma2 9B 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
- [IndoMMLU](https://arxiv.org/pdf/2310.04928)
- These tasks include examination questions on Humanities, Indonesian language, Local languages and cultures, Social science and STEM across primary, middle, and high school levels.
- and the well known [English MMLU](https://arxiv.org/pdf/2009.03300)
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.
