DeepSeek to launch V4.1 Flash model, undercutting V4 Pro on cost and speed

DeepSeek confirmed it will officially release its V4.1 Flash model on September 10, 2026 (Beijing Time), stating internal testing shows it outperforms V4 Pro on performance, cost, speed, and task completion time. Until V4.1 Pro arrives, all Pro-model requests will be automatically redirected to V4.1 Flash and charged at the cheaper Flash pricing tier.

StartLux's 27B local model nearly matches DeepSeek-V4-Pro in CAICT MCP test

A newcomer called StartLux, founded by veteran programmer Chen Danyan and formerly known as Yuandian Xinghui, placed second in China's CAICT MCP specialized benchmark with its StartLux-V1.0-27B-Preview model. The 27-billion-parameter model trailed DeepSeek-V4-Pro, a 1.6-trillion-parameter system, by just 1.3 percentage points, despite running locally on consumer-grade PCs rather than in the cloud. Chen has argued that local models will eventually outcompete cloud-based ones on efficiency and market share.
