DeepSeek releases V4.1-Flash: multimodal MoE with 1M token context
DeepSeek launched V4.1-Flash, its smallest new-architecture model: a 552B-parameter multimodal MoE with native vision, 1M-token context, 4x smaller KV cache, and claimed setup costs 1/40 of Claude's. It is now available on Fireworks, FLock, and Ollama.
