DeepSeek previews latest upgrade of its hit AI model

Chinese startup DeepSeek released "preview" versions of a new artificial intelligence model on 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. 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 company added.
