DeepSeek-V4.1-Flash is a multimodal mixture-of-experts model for coding, reasoning, visual understanding, and tool-using agents. It processes text and images, generates text, and combines a 1M-token context window with continuously adjustable reasoning effort. Its Causal Encoder-Decoder architecture, sparse attention, and compressed KV cache reduce the memory and computation required for long inputs, making it well suited to large-codebase work, document analysis, research, and sustained agentic tasks.
LLM Gateway routes requests to the best providers that are able to handle your prompt size and parameters.
