Why This Matters

DeepSeek has shipped V4.1-Flash on its API, folding vision into a single natively multimodal model rather than a separate experimental variant. The older V4-Flash and V4-Flash-Vision-Exp are retired, with their model names temporarily redirected for compatibility. For developers, it signals continued rapid iteration and consolidation in the low-cost, fast-inference tier of the model market.

Key Takeaways

V4.1-Flash is live on the DeepSeek API under the model name deepseek-flash, with native multimodal support built in.
V4-Flash and V4-Flash-Vision-Exp are retired; their old identifiers temporarily route to V4.1-Flash.
