DeepSeek offers a two-day V4.1 beta

DeepSeek opened a limited beta of V4.1 Flash that expires September 10, with a model identifier ending in expires-on-0910 and a 20-request concurrency cap, according to TechNode’s report. The interim model reportedly adds native multimodal support and keeps V4 Flash pricing, but DeepSeek has not presented it as a formal release with an independent benchmark record. Treat this as a short bake-off window, not production dependency: DeepSeek’s vision API economics make the provider interesting for image-heavy agents, while an expiring model cannot anchor a service-level promise.
