Pundi AI, previously known as Function X (FX), is a blockchain-based platform developed by Pundi X Labs. The platform rebranded to Pundi AI in 2024, shifting its focus toward integrating AI with blockchain technology. Its primary product, the Pundi AI Data Platform, is a decentralized marketplace where users can contribute, tag, verify, and trade AI training data as intellectual property, often in the form of NFTs.

Pundi AI operates as an omnichain infrastructure, meaning it connects to multiple blockchain networks. Key features include the "Tag to Earn" model, where users are rewarded for annotating data, and the AI Data Marketplace, which enables the trading or licensing of datasets for AI model training. The platform uses the PUNDIAI token (a rebranded version of the FX token) for transactions and rewards. Pundi AI also builds on Pundi X’s earlier work, like the XPOS device, to bridge crypto payments with real-world applications, now extending into AI data solutions.
