DeepSeek launched V4.1-Flash today, the smallest model in a new architecture family with native multimodal vision. The new design targets higher ceiling, faster inference, and larger throughput, and is meant to scale to bigger models. V4.1-Flash scores 90.9 on GPQA Diamond, 3471 Codeforces rating, and 36.8 on HLE. Set model name to deepseek-flash in the API; old V4 Flash and V4 Flash Vision Exp are offline and requests are temporarily routed to V4.1-Flash. DeepSeek also claims V4.1-Flash beats V4 Pro on performance, cost, and speed, so V4 Pro requests will be routed to V4.1-Flash starting Sep 14 and billed at Flash rates. API pricing is cut, but the post doesn't list the new numbers—check the pricing page.

DeepSeek V4 Pro is now GA, with major agent workflow gains and adjustable reasoning effort—low for simple tasks, high for daily agent work, max for complex ones. It natively supports the OpenAI Responses API and one-click Codex setup. API pricing shifts to peak/off-peak on Aug 16: off-peak is 50% cheaper. Model names stay the same; try it via Expert Mode on the app.
