By PulseAugur Editorial · [1 sources] ·

DeepSeek V4.1 Flash 1017, released on October 17, demonstrates strong performance on coding tasks, solving all 30 small edit-and-test coding tasks with its "thinking" feature disabled. When the "thinking" feature was enabled, the model performed even better on single-shot reasoning tasks, solving all 39 questions compared to 11 when thinking was off. The model's weights are open-source and available on Hugging Face, with pricing remaining consistent with its predecessor. AI

IMPACT Offers flexible reasoning capabilities for coding and single-shot tasks, potentially reducing costs for specific applications.
