DeepSeek R2: The Most Anticipated Model That Never Shipped
DeepSeek R2 has never been released. As of July 2026 it does not appear in DeepSeek's official API model list, which contains only V4-Flash, V4-Pro and two legacy aliases being deprecated on July 24, 2026. Reuters reported that founder Liang Wenfeng was not satisfied with R2's performance and no timeline was ever set. What DeepSeek shipped instead is V4, released April 24, 2026, whose thinking mode is the reasoning model people are actually searching for. Every R2 spec in circulation comes from unconfirmed leaks.
