DeepSeek: DeepSeek V4 Flash 0731

Deepseektext
8.9 / 10 Overall Rating

DeepSeek V4 Flash 0731 is a 284B total (13B active) sparse Mixture-of-Experts model designed for high-throughput coding, reasoning, and agentic workflows. It offers an expansive 1.3M-token context window and output generation up to 943K tokens at roughly 1/50th the input cost of GPT-4o and Claude 3.5 Sonnet. While ideal for massive document processing and rapid agent execution, its lightweight active parameter count limits high-level reasoning depth on complex edge cases.
