Question: Is there a decentralized machine learning network that integrates with DeFi applications and allows for direct connections to web apps and NFT marketplaces?

If you're looking for a decentralized machine learning network that can plug into DeFi apps and connect directly to web apps and NFT marketplaces, Arbius is arguably at the head of the pack. The network is geared for decentralized AI model generation at market rates, with tokenized models and base fees for invocations. It's got DeFi integration and rewards solvers for optimizing their software for speed so they make more money. You can participate by paying for AI generations, participating in governance, earning fees through delegation, staking liquidity provider positions and validating the network.

Another contender is AIxBlock, which offers a decentralized supercomputer for AI work. It's got a peer-to-peer decentralized compute marketplace and a data engine for sourcing and labeling data. AIxBlock's platform includes tools like Jupyter Notebook, Docker and Kubernetes, so it's geared for AI developers. It's got a secure, transparent and seamless payment system for renting compute resources and participating in AI projects, which means compute costs are lowered while AI data quality is improved.

For real-time AI model interactions and fine-tuning, Exthalpy offers a serverless and decentralized platform. It can handle large language models in real-time, for example powering chatbots and personalized product recommendations. Exthalpy's architecture means there are zero recurring storage costs and live data is always available, so it's good for real-time enterprise knowledge management and product analysis. The platform is highly scalable, with options for detailed reporting and performance analysis.
