The model carries 2.8 trillion parameters and a 1-million-token context window, putting it in a category with very few peers globally.

On July 23, 2026, Michael Kratsios, director of the White House Office of Science and Technology Policy, publicly accused Moonshot AI of accessing compute resources through servers located in Thailand. The allegation is that this arrangement was used to distill and replicate U.S. models, including Anthropic’s Fable, effectively circumventing export controls through geographic workarounds. Moonshot has not publicly confirmed or denied the specifics of the accusation. The Blackwell chip question is bigger than one startup Ki...
