DeepSeekMultimodal Model

DeepSeek V4.1 Flash

DeepSeek's efficient V4.1 Flash tier: a natively multimodal 552B-parameter sparse Mixture-of-Experts tuned for coding, cybersecurity, and agentic workloads, with image input, tool calling, a 1M-token context, and a continuously controllable reasoning-effort dial. Near-frontier agentic quality at a small fraction of frontier pricing.
