DSeek has announced the upcoming release of its V4.1 Flash AI model, scheduled for September 10, 2026, Beijing Time. Following extensive testing, the new model has demonstrated improvements over the existing V4 Pro model in key areas such as performance, cost, speed, and task completion time. To ensure a smooth transition, all requests to the V4 Pro model will be redirected to V4.1 Flash and billed at the Flash model's pricing until the V4.1 Pro version is available. Users are encouraged to provide feedback during this period to help refine the model. Alongside the launch, DSeek will implement new pricing for the Flash series starting at noon on the release date. Off-peak rates will be set at $0.003 for input cache hits, $0.15 for input cache misses, and $0.6 for output, with peak-hour prices doubling these amounts. This pricing adjustment aims to optimize resource usage and cost efficiency for users.
