DeepSeek V4.1 Flash 1017 released, leading open-weight models in key benchmarks

By PulseAugur Editorial · [1 sources] ·

DeepSeek has released V4.1 Flash 1017, a 552B-parameter Mixture-of-Experts model with a 1 million token context window, available via multiple APIs. Artificial Analysis reports this model achieves a score of 45 on their Intelligence Index, tying it for second among open-weight models and showing significant improvements in agentic capabilities and reduced hallucination rates. While it excels in areas like code generation and browser use, some evaluations suggest it may not outperform competitors like MiMo-V2.6-Pro or GPT-6.1 Sol in all aspects, and there are some concerns about its performance on specific tasks and potential benchmark manipulation. AI

IMPACT Sets a new benchmark for open-weight models in context window and agentic tasks, potentially influencing pricing and development strategies for competitors.
