In Cortex, due to the nature of open source and competitive mechanisms, the best model as an intelligent agent will survive to enhance the intelligence level of the Blockchain network. 
Cortex's main mission is to provide the state-of-the-art machine-learning models on the blockchain in which users can infer using smart contracts on the Cortex blockchain. One of Cortex's goals also includes implementing a machine-learning platform that allows users to post tasks on the platform, submit AI DApps (Artificial Intelligence Decentralized Applications).

Pros

Cortex also provides a submission interface for training off-chain, including the instruction-interpreting virtual machine for models. This will setup a bridge between computing power providers and algorithm providers for trading and collaboration. Cortex has its own Virtual Machine, called the Cortex Virtual Machine (CVM). The CVM instruction set is fully EVM compatible and has support for inference instructions.

Cons

Machine learning researchers around the world can upload well-trained corresponding data models to the storage layer. Other users who need this AI models can make inferences by using models and pay to their providers. I think it's not really safe
