The gap between open and closed AI models in cyber capabilities keeps shrinking OpenAI's GPT-6 Sol Daybreak achieved 80.8 percent of attack objectives in simulated corporate networks on the Vals AI benchmark, while the open-weight DeepSeek V4.1 Flash reached 72.8 percent at a tenth of the cost, The Decoder reported. Analysts cited by The Decoder said the narrowing gap between closed and open models in cyber capabilities leaves defenders a shrinking window, since open models can no longer be restricted. In the Vals AI benchmark, OpenAI's GPT-6 Sol Daybreak hits 80.8 percent of attack objectives in simulated corporate networks. Worse, the open-weight model DeepSeek V4.1 Flash reaches 72.8 percent at a tenth of the cost. Because open models can no longer be restricted, analysts say the window for defenders is shrinking fast.
