0G Labs has officially launched the Galileo V3 testnet, marking a key step in its development of a decentralized operating system for artificial intelligence. The platform aims to bring AI fully on-chain, offering performance improvements of up to 50,000 times faster and 100 times cheaper than existing solutions. Users can participate by connecting EVM-compatible wallets to the Zero Dex, performing token swaps, and providing or removing liquidity. Faucet tokens are available for claim to facilitate engagement with the testnet. Concurrently, OpenLedger is advancing decentralized AI infrastructure with new AI models such as Web3 Guardian, a smart contract risk detector, and GreenGuard SLM, a vision AI model designed to monitor environmental issues like illegal deforestation and pollution through satellite and drone imagery. OpenLedger emphasizes transparency and verifiability in AI, addressing concerns about traditional AI models being opaque. Additionally, OpenLedger has partnered with 0G Labs to further develop on-chain AI solutions within the Web3 ecosystem.
