MaLLaM 🌙 5B (Malaysia Large Language Model), Pretrain 5B 4096 context length on Malaysian text

Pretrain from scratch 5B parameters using Mistral architecture on 90B Malaysian text tokens.

README at https://github.com/mesolitica/malaya/tree/5.1/pretrained-model/mistral

• Trained on 90B tokens, gathered at https://github.com/malaysia-ai/dedup-text-dataset/tree/main/pretrain-llm
• We use Ray cluster to train on 5 nodes of 8x A100 80GB, https://github.com/malaysia-ai/jupyter-gpu/tree/main/ray
