OpenAI to Z Challenge

Unveiling Amazonia's Ancient Secrets with AI

The Amazon: A Realm of Untold Histories

For centuries, the vast Amazon rainforest, stretching over 6,000,000 square kilometers across nine South American countries, has captivated imaginations with legends of "lost cities" like Z, Paititi, and El Dorado. Historically perceived as a "pristine wilderness," recent archaeological advancements are revealing a different story: a landscape once home to an estimated 8 to 10 million people as far back as 8,000 years ago. These ancient societies engineered their environment, building complex settlements and transforming the forest into a "vast cultivated garden." The OpenAI to Z Challenge invites digital explorers to leverage cutting-edge AI and open-source data to uncover these hidden histories, potentially rewriting our understanding of pre-colonial Amazonia.

The Digital Explorer's Toolkit

Traditional archaeological fieldwork in the Amazon faces immense challenges due to dense canopy and vast terrain. The OpenAI to Z Challenge champions a new era of discovery, powered by advanced AI models and a diverse array of open-source data. This digital toolkit enables researchers to "see" beneath the foliage and analyze complex information at an unprecedented scale.

Core AI Models: The Brains of the Operation

OpenAI's o3/o4 mini models provide powerful visual perception for analyzing satellite and LIDAR imagery, while GPT-4.1 excels at processing vast textual datasets from historical records and academic papers, unlocking contextual clues.
