DeepSeek’s Flash beta targets Pro-level capability at Flash speed
DeepSeek is testing V4.1 Flash as a short-lived API beta, not launching a finished model. The new architecture handles multimodal inputs natively, and testers can call it through the existing endpoint by selecting `deepseek-v4.1-flash-expires-on-0910`; pricing matches V4 Flash, with up to 20 concurrent requests per account. If the speed and cost claims hold, the real pressure lands on premium models, not just competing Flash variants.
