SUPA-AI does not own this model and had no hand in making the original, we simply converted it to a guff format to be usable on ollama, you can find the original model here: https://huggingface.co/GoToCompany/gemma2-9b-cpt-sahabatai-v1-base

Gemma2 9B 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 Gemma2 9B CPT Sahabat-AI v1 base model which has undergone continued pre-training from the Gemma2 9B CPT SEA-Lionv3 base model.
Model Details
Model Description
The continued pre-training data for Gemma2 9B 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: Gemma Community License
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 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. - These tasks consist of IFEval, BBH, Math Lvl 5, GPQA, MuSR, and MMLU-PRO. - Caveat: Our results differ from the HuggingFace LLM Leaderboard because we have used VLLM 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.
