Background & analysis
On November 2, 2026 at 09:03, TMTPost reported that DeepSeek officially launched V4.1 Flash-1017, a new large model release. Although public data had already surfaced technical indicators for the model, this launch marked the first time DeepSeek independently released a Pareto frontier curve presenting its combined efficiency-cost position. According to the data in that curve, V4.1 Flash-1017's comprehensive per-task cost is only one-hundredth to one-twentieth of comparable models such as Fable and Astra, implying a cost-performance advantage of more than forty to fifty times. The report also stated that testing showed token usage dropping by more than 50% versus the previous version across most scenarios, with the corresponding TCO level expected to fall substantially as well. As of that report, the available information consisted solely of the curve and the cost figures, and no further progress had been disclosed.
