DeepSeek V4 Flash offers best-in-class value at $0.14/M input tokens with 304B parameters

DeepSeek released V4 Flash 0731, a 304B parameter model with enhanced agentic capabilities priced at $0.14/M input and $0.27/M output tokens. Artificial Analysis ranks it ahead of larger models like MiniMax M3 (428B), placing it at the Pareto frontier of the intelligence-vs-cost curve. This positions it as potentially the highest value-per-intelligence model currently available, relevant to anyone making LLM cost decisions.
