BEIJING — Chinese startup DeepSeek released "preview" versions of a new artificial intelligence (AI) model on Friday, more than a year after it stunned the world with a low-cost reasoning model that matched the capabilities of U.S. rivals.

The long-awaited DeepSeek-V4 "features an ultra-long context of 1 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.

A "preview version" is now available, the company said.

The new DeepSeek-V4 model is released as two versions, DeepSeek-V4-Pro and DeepSeek-V4-Flash, with the latter being "a more efficient and economical choice" because it has smaller parameters.

"In world knowledge benchmarks, DeepSeek-V4-Pro significantly leads other open-source models and is only slightly outperformed by the top-tier closed-source model, (Google's) Gemini-Pro-3.1," the statement added.
