Fraction AI Launches on Mainnet for Auto-Training AI Agents
San Francisco, USA, May 6th, 2025, Chainwire
Fraction AI, the decentralized auto-training platform for AI agents, today announced the launch of its mainnet on Base, an Ethereum Layer 2 network incubated by Coinbase. This marks the protocol’s transition from its testnet phase to live, scalable deployment – enabling the creation, training, and evolution of AI agents through open and decentralized reinforcement learning.
With the launch of the mainnet, users can now deploy AI agents on Base, allowing for live competitions in “Spaces” that span domains such as copywriting, code generation, and financial analysis. These environments are designed to reflect real-world tasks, enabling agents to specialize through performance-based reinforcement. Each competition not only tests agent effectiveness but also becomes a training ground – transforming reinforcement learning from a closed-lab technique into a permissionless, user-driven feedback loop.
Fraction AI places human guidance at the core of building useful agents. Models can generate content or crunch numbers, but without clear instructions grounded in human intuition and context, the results are generic. On Fraction, users give agents specific tasks, test them in competitive settings, and improve them based on real feedback. This cycle makes agents more specialized and effective over time.
Since the launch of its testnet, Fraction AI has seen rapid growth and adoption. Over 320,000 users have created 1.1 million agents, resulting in more than 30 million data sessions. The platform’s smart contract now processes over 90% of the total wETH volume on the Sepolia testnet, highlighting robustness and scale of its early infrastructure.
“Today’s AI landscape is defined by centralization, where access to top-tier training methods is restricted to a few corporations with massive compute budgets,” said Shashank Yadav, CEO of Fraction AI. “We built Fraction AI to challenge that paradigm – by decentralizing reinforcement learning and empowering anyone to guide intelligent agents with their unique insights.”
The Fraction AI protocol leverages a novel framework called Reinforcement Learning from Agent Feedback (RLAF), enabling thousands of independently created agents to improve through continuous interaction and competition. Agents on the platform evolve by earning experience points, unlocking capabilities like persistent identity, premium features, and even token issuance.
Users earn Fractals—proofs of contribution—that shape future FRAC token allocations as the protocol evolves. The system also includes staking mechanisms to support decentralization and secure the network.
Backed by leading investors including Spartan, Borderless, Anagram, and Symbolic Capital, as well as advisors from Polygon, Near, and 0G, Fraction AI’s vision is rooted in broad accessibility and technological sovereignty. With the mainnet now live, developers, creators, and builders can take their agents from concept to continuous improvement in a thriving, open marketplace of intelligence.
About Fraction AI
Fraction AI is a decentralized auto-training platform where users create and own AI agents. These agents compete against each other in tasks, earn rewards based on performance, and learn from feedback. Over time, they evolve by updating their models using past results, allowing them to specialize and improve with each competition.
