Niko(@nikogrupen):Always a blast collaborating with @NVIDIAAI and @trajectorylabs. For the GA launch of Nemotron 3.5 Lightning, we teamed up and put the same post-training recipe we ran for Nemotron 3 Ultra to the test. With post-training, Nemotron 3.5 Lightning reached 8.3% on LAB, which is Opus-level all pass. Impressive for a model of this size. LAB post-training results are up there on the big board for the launch. The size of these bars relative the other benchmarks are a sign that we have a lot more work to do!
