China's DeepSeek says releases long-awaited new AI model

Chinese startup DeepSeek released "preview" versions of a new artificial intelligence model Friday, more than a year after it stunned the world with a low-cost reasoning model that matched the capabilities of US rivals.

The long-awaited DeepSeek-V4 "features an ultra-long context of one million words, achieving leadership in both domestic and open-source fields across agent capabilities, world knowledge, and reasoning performance", the company said in a statement on social media.
