DS V4.1 Flash 1017 is among the best models in absolute performance on this cybersecurity benchmark, and is ~50x cheaper than Astra. As I have emphasized before, despite its small size, the special architecture of the model (eg innovations like engram) may allow it to punch above its weight in absolute capability as well as cost. DS are very confident that the can continue to improve with RL. The jump from the first release to 1017 is very impressive.
