Capabilities
About OLMo 1B
AMD OLMo 1B is a fully open-source large language model with 1 billion parameters, designed for advanced reasoning, instruction-following, and chat capabilities. Utilizing a decoder-only transformer architecture, it is trained on a 1.3 trillion-token subset of the Dolma v1.7 dataset, achieving a remarkable training throughput of 12,200 tokens per second per GPU. AMD leveraged its Instinct MI250 GPUs across 16 nodes to optimize performance, followed by a sophisticated three-stage training process of pre-training, supervised fine-tuning, and direct preference optimization.
