Cortex Labs

Running an AI model inside a smart contract is the problem Cortex Labs goes after. Cortex is an open-source, peer-to-peer blockchain platform where you upload AI models and have them executed on a distributed network, then call them from smart contracts.

That makes it a developer tool for building AI-enabled decentralized applications (DApps) without sending inference off-chain.

Two pieces of the stack do the heavy lifting.

The CVM, short for Cortex Virtual Machine, handles on-chain execution of models.

MRT covers quantization and integer-only inference, which matters because blockchains need results that come out identical on every node.

Floating-point math is a poor fit for that.

The stated goal is AI democratization, meaning anyone can publish a model and anyone can integrate it.

Cortex Labs suits you if you already work with smart contracts and want models as a native part of them.

It is a narrow niche, and a blockchain-focused one.
