This particular model release is interesting because not only is it open weights[0], but they also released most of the pretraining and posttraining data along with the code and libraries for the RL environments (much like Olmo3, which came out recently). It is also trained from scratch and architecturally different from the existing Qwen and DeepSeek templates. It is frontier performance for its weight class. Two larger model releases are to follow soon. [0] Not exactly open source, though—it’s Nvidia Open Model License. Comments
