Mexico to Build 'Coatlicue' Supercomputer — A 314-Petaflop Leap for AI

Mexico has unveiled plans to build Coatlicue, a supercomputer projected at 314 petaflops that officials say will be Latin America’s most powerful. Construction is expected to begin next year, though a location has not been finalized. The government says the system will expand capabilities for artificial intelligence, climate modeling and other data-intensive research. For comparison, current leading systems in the region operate at much lower petaflop levels.

Mexico to Build 'Coatlicue' Supercomputer — A 314-Petaflop Leap for AI

Mexico announced plans to build a new supercomputer named Coatlicue, which officials say will become the most powerful system in Latin America with a projected capacity of 314 petaflops. The machine is named after the Mexica earth-mother goddess and is intended to dramatically expand the country’s computing power for research and artificial intelligence applications.

President Claudia Sheinbaum said a site has not yet been selected, but construction is scheduled to begin next year. "We’re very excited," Sheinbaum said. "It will allow Mexico to fully engage in the use of artificial intelligence and process data at scales we currently cannot handle." Sheinbaum, an academic and climate scientist, framed the project as a strategic investment in science, technology and national capacity.

José Merino, head of the Telecommunications and Digital Transformation Agency, provided the 314 petaflops figure and noted current regional systems operate at much lower speeds. For context, Mexico’s present top system runs at about 2.3 petaflops. If realized, Coatlicue’s capacity would place it far above existing Latin American installations.

What the numbers mean

A petaflop measures computing speed: one petaflop equals one quadrillion (10^15) floating-point operations per second. A 314-petaflop system can perform enormous volumes of calculations per second, enabling faster training of large AI models, higher-resolution climate and weather simulations, advanced genomics and other data-intensive scientific work.

Intended uses and next steps

Officials say Coatlicue will be used for a wide range of national priorities, including AI research, climate science, public health, and large-scale data analysis across government and academia. The government expects to define the site, procurement timeline and partnerships over the coming months as it moves toward construction.

Officials emphasize: the announced capacity and timelines are proposals subject to planning, funding and procurement processes. Further technical details, including architecture, power and cooling requirements, and international collaboration, have not yet been released.
