What Makes Claude Opus 5 Different?
DeepSeek V4 Flash 0731 is a sparse mixture-of-experts model with 284B total parameters but only 13B active per token. This architecture is what makes it special — it delivers near-frontier quality at a fraction of the compute cost, which shows up as very low pricing on OpenRouter.
Three features define DeepSeek V4 Flash 0731's pitch. The first is the 1.3M token context window — enough to hold entire repositories and long task histories in one session. The second is the sparse MoE design that keeps both cost and latency low. The third is DeepSeek's open-weight philosophy, which has made its models widely adopted across the developer community.
DeepSeek V4 Flash 0731 also supports tool calling, structured outputs, and other agent-friendly features, making it a practical choice for production agentic workloads and automated pipelines.
