DeepSeek V4.1 Flash 1017 improves benchmarks without price hike

By PulseAugur Editorial · [1 sources] ·

DeepSeek has released an updated version of its V4.1 Flash model, named DeepSeek-V4.1-Flash-1017, which offers improved performance across various benchmarks without any change in token pricing. This update, achieved through five additional weeks of reinforcement-learning post-training, results in faster task completion and shorter outputs. The unchanged pricing, coupled with performance gains, suggests a potential shift in model selection economics from a per-token cost to a cost-per-completed-task basis for users routing agent workloads. AI

IMPACT This update may shift model selection towards cost-per-completed-task due to improved performance at stable prices.
