DeepSeek launches V4-Flash-0731 public beta, matching frontier performance at a fraction of the cost
DeepSeek released the official V4-Flash-0731 API in public beta, scoring 50 on the Artificial Analysis Intelligence Index, a 10-point jump over its April V4-Flash release. The model lands on par with Meta's Muse Spark 1.1 and beats OpenAI's GPT-5.6 Luna, while its cost per task on DeepSeek's first-party API comes in roughly 60% lower than GPT-5.6 Luna even after OpenAI's 80% price cut.
