US introduces new export rules for advanced AI chips

The U.S. government has announced new regulations to control the export of advanced AI chips, specifically graphics processing units (GPUs). These chips are crucial for training sophisticated AI models, like OpenAI's ChatGPT. The new rules limit the total processing power of GPUs that can be exported to certain countries, capping it at 790 million total processing performance (TPP) through 2027. Companies with special authorizations can bypass these caps. Eighteen countries, including Australia, Canada, and Japan, are exempt from these restrictions. Additionally, small orders of GPUs and those for gaming do not count toward the caps, allowing for easier access to U.S. chips.
