IT Home On October 16, local time on October 15, Meta released the open-weight AI model Muse Spark Open. Meta officially claims that this is the most powerful open-weight model in the United States so far.
According to The Next Web, Meta said that the performance of Muse Spark Open is lower than that of the cutting-edge model Muse Wonder, which was released on Monday.
Meta announced on Monday that Muse Wonder had reached the frontier model level, but did not release any benchmark test results. The model remains closed-source at present.
Meta’s Chief AI Officer, Alexandr Wang, said that due to both security and capability considerations, we usually do not make our most advanced models open source. However, he added that Meta plans to continue releasing excellent open-source models.
It is reported that this is the second open-source release of the Muse series AI models under Meta. In August this year, Meta released the 30 billion-parameter model Glimmer, distilled from Muse Spark, under the Apache 2.0 license.
IT Home noticed that Meta’s founder’s statement five weeks ago was completely opposite to this. Zuckerberg said on the Sources podcast that it is “extremely dangerous” for competitors to train more advanced models without making them public (he did not name any specific companies at that time).
