AI Arena is a web3/AI gaming company built by ArenaX Labs, backed by Paradigm and Framework Ventures. Its flagship title, AI Arena, is an Ethereum/Arbitrum-native PvP fighting game where players purchase, train through imitation learning, and battle characters powered by real artificial intelligence, with a native $NRN (Neuron) token and an on-chain marketplace for AI models. Beyond the game, ArenaX Labs ships developer infrastructure for reinforcement learning: RLMesh, an open-source, Gymnasium-compatible framework that connects RL models to environments across process, dependency, and machine boundaries over a gRPC wire protocol (rlmesh-wire-v1), with Python and Rust SDKs; and SAI (competesai.com), a gamified RL research and competition platform with its own CLI. This profile was enriched by the API Evangelist pipeline from public sources — GitHub, package registries, and the RLMesh documentation.
