美国开源权重模型一周连发三款：Nemotron 3.5、Muse Spark Open、Beam 1.0
美国开源模型一周发了三款，Meta 的 Muse Spark Open 拿下 38.9 分刷新纪录，NVIDIA 和 Reflection 的新模型也在追赶，智能与参数效率对比值得看看。
上周美国开源权重模型密集更新。NVIDIA 发布 Nemotron 3.5 Bolt 和 Nemotron 3.5 Super VL，后者以 120B 参数在 Intelligence Index 得到 26.5 分，将 Inkling Small 挤出 Pareto 前沿。Meta 的 Muse Spark Open 得到 38.9 分，领先 Super VL 超过 12 分，创下美国开源权重模型的最高智能分。Reflection 首个模型 Beam 1.0 以 501B 参数得到 30.3 分，落在 Super VL 与 Muse Spark Open 之间。
US open-weights models made gains in both intelligence and parameter efficiency last week:
➤ Thursday morning: NVIDIA released Nemotron 3.5 Bolt and Nemotron 3.5 Super VL. Super VL scored 26.5 on the Intelligence Index with 120B parameters, pushing Inkling Small off the Pareto frontier
➤ Thursday midday: Meta's Muse Spark Open scored 38.9, more than 12 points ahead of Super VL and the highest intelligence yet for a US open weights model
➤ Friday morning: Beam 1.0, Reflection's first model, scored 30.3 with 501B parameters, joining the frontier between Super VL and Muse Spark Open
