Chinese scientists introduce Spikingbrain-1.0, an AI model that resembles human nervous system operations
In a groundbreaking development, a research group led by Tsinghua University, in collaboration with scientists from the University of California, Berkeley, has unveiled SpikingBrain-1.0. This artificial intelligence (AI) system, inspired by the human brain, marks a paradigm shift in the field, moving away from brute-force models and infinite data towards the elegant efficiency of biology.
The team behind SpikingBrain-1.0 comprises Li Guoqi and Xu Bo, with Xu Bo, director of the Automation Institute, stating that this system opens a non-Transformer technical path for the next generation of AI. The system uses electrical spike neural networks, mimicking the way biological neurons communicate, and is ideal for tasks requiring analysis of ultra-long sequences, such as legal document review, medical data exploration, high-energy physics experiments, or DNA sequence modeling.
The SpikingBrain model achieves comparable performance to traditional models like ChatGPT, but with only 2% of the training data. In tests, a variant of the system showed a 26.5x speed improvement over Transformer architectures in generating the first token from a context of a million tokens.
Efficiency in processing long sequences opens up possibilities for more accurate medical diagnostics, genomic analyses, and the management of large volumes of legal and scientific information. The key to SpikingBrain lies in its event-driven spike neurons, which only activate when necessary, offering a viable solution to the energy consumption crisis in AI.
The development of SpikingBrain-1.0 on a domestic Chinese GPU platform also reduces China's dependence on US chips. Moreover, the Speck neuromorphic chip, developed by the Chinese Academy of Sciences in collaboration with Swiss researchers, consumes only 0.42 millivolts at rest, approaching the efficiency of the human brain. China presented the Darwin Monkey supercomputer, with over 2,000 million artificial neurons, further demonstrating the country's commitment to AI research.
However, the international community is debating the carbon footprint of AI. Training a state-of-the-art model consumes as much electricity as tens of thousands of households per year. The release of SpikingBrain-1.0 in open-source format and the launch of a public testing platform, accompanied by a bilingual technical report, aims to encourage further research and collaboration in this area.
Inspiration from neuroscience can offer disruptive technological solutions in artificial intelligence. The launch of SpikingBrain-1.0 represents a significant step towards more efficient, sustainable, and human-inspired AI systems.
