DeepSeek is causing havoc throughout the AI industry. U.S.-based tech companies that have heavily invested in AI saw their stocks take a tumble this week after the China-based startup released a new AI model on par with OpenAI's latest model, yet much cheaper to train — plus, DeepSeek made it free and open source.
