DeepSeek’s MIT-licensed update lifts Terminal-Bench to 42.3
DeepSeek-V4.1-Flash-1017 gives developers a freely licensed model they can run locally, with the model card reporting a Terminal-Bench 4.0 score of 42.3, up from 31.2 for the earlier V4.1-Flash. It is a minor weight update aimed at reasoning, coding, agent tasks, and visual work, while reducing execution time and output length. The card lists a 1M-token context window and shows DeepSWE v1.1 at 77.0, versus 74.2 for its predecessor.
