China’s DeepSeek launched preview versions of its long-awaited V4 model, breaking months of silence from one of the country’s most closely watched AI labs. V4-Pro’s agent ability has significantly improved from previous models, the company said on its official WeChat account on Friday. The model is now the “go-to agentic coding model” internally, with feedback showing that it beats Anthropic’s Sonnet 4.5 in user experience and delivering output quality closer to Opus 4.6’s non-thought mode, though it still lags behind Opus 4.6’s thought mode, they note. The release ends a drawn-out wait for a major update model from DeepSeek. While the company repeatedly delayed releasing a major model update, domestic rivals including Moonshot AI’s Kimi, MiniMax, Alibaba Group and ByteDance have aggressively pushed out updates.
