DeepSeek, a Hangzhou-based startup founded in 2023, shot to the top of Apple’s App Store free app chart after releasing a new open-source AI model it says rivals OpenAI's work. Its website was hit by outages amid a spike in interest.

The little-known artificial intelligence firm has emphasized research, even as it emerged as the brainchild of a hedge fund.

The Chinese artificial intelligence firm DeepSeek has rattled markets with claims its latest AI model performs on a par with those of OpenAI, despite using less advanced, more energy efficient computer chips.

Entrepreneur Marc Andreessen, known for co-writing Mosaic, one of the world’s first web browsers, wrote Sunday on X that “DeepSeek R1 is AI’s Sputnik moment,” likening it to the space race between the U.S. and the Soviet Union and the event that forced the U.S. to realize that its technological abilities were not unassailable.

Alibaba claims that its Qwen2.5-Max artificial intelligence model outperformed its rivals at OpenAI, Meta and DeepSeek.

Alibaba says it's new artificial intelligence model is superior to DeepSeek. It says the Qwen 2.5 Max edition scored better than Meta Platforms Inc.’s Llama and DeepSeek’s V3 model in various tests. Matthew Bloxham of Bloomberg Intelligence is on ".
