英伟达 Nemotron 3 Ultra 得分 48，但这足以追赶中国吗？
英伟达的 nemotron 3 ultra 以 48 分的基准测试成绩领跑美国开源模型，但仍落后中国的 kimi k2.6 6 分。这缩小了高性能开源 AI 的差距。
nvidia's nemotron 3 ultra is now the highest-scoring open ai model from the us, reaching 48 points on the artificial analysis leaderboard, beating google's gemma 4 31b. despite this win, it lags behind china's moonshot kimi k2.6, which holds a 6-point lead, and the closed-source opus 4.8 by a larger margin. performance benchmarks show nemotron generating over 300 tokens per second on deepinfra, vastly outpacing the 50-100 tps speeds of comparable chinese models. nvidia plans a full release on june 4 via hugging face and openrouter. this release intensifies the race for open-source dominance between us and chinese developers.
