Researchers from Tsinghua University and others have introduced MathGLM, a 2 billion parameter language model that outperforms GPT-4 with nearly 100% accuracy in arithmetic tasks. MathGLM utilizes a decoder-only architecture and has significantly improved its mathematical capabilities through training on a large-scale arithmetic dataset. It also surpasses models like GPT-4 and ChatGPT in handling complex mixed arithmetic operations with intricate numerical formats.
