Elon Musk says Colossus 2 is simultaneously training 7 models, with a maximum of 10 trillion parameters.

AIMPACT News, April 8 (UTC+8), SpaceX and xAI founder Elon Musk posted on X that the SpaceXAI supercomputing cluster Colossus 2 is currently training 7 models simultaneously:

1. Imagine V2, the next-generation version of the image and video generation model

2. Two variants of a 1 trillion parameter model

3. Two variants of a 1.5 trillion parameter model

4. A 6 trillion parameter model

5. A 10 trillion parameter model

He added, “There are still some catching up to do.” Previously, multiple media outlets reported that xAI’s next-generation flagship model Grok 5 has approximately 6 trillion parameters, which matches the 6T in the list. The 10 trillion parameter model has not been publicly reported before.

In the post, Musk referred to the entity formed by the merger of SpaceX and xAI as “SpaceXAI.” The two companies completed their merger in February this year, with a combined valuation of about $1.25 trillion. Colossus 2 went online on January 17, and is the world’s first gigawatt-level AI training cluster, planned to be upgraded to 1.5GW this month. (Source: X platform)
