About DeepSeek V4.1 Flash

DeepSeek-V4.1-Flash is the lightweight flagship of DeepSeek's new architecture family, packing 552B total MoE parameters to deliver flagship-surpassing intelligence across key benchmarks, including out-performing DeepSeek-V4-Pro. It adopts a Causal Encoder-Decoder asymmetric design with 8B active parameters for input and 16B for output, and offers native multimodal visual understanding. KV Cache usage is cut to one-quarter of the previous generation's HBM and one-eighth of its SSD storage, dramatically lowering costs for long-context and agentic workloads. With a 1M-token context window and up to 384K-token maximum output, it balances high throughput, low latency, and exceptional cost efficiency.

DeepSeek V4.1 Flash is a chat model by DeepSeek, available on Eden AI through 9 endpoints from 9 providers, from $0.098 per million input tokens and $0.39 per million output tokens, with a context window of up to 1.05M tokens.
