Multi-step AI programs that run fast.

Build using a cohesive modular API with optimized models, colocated file and vector storage, a code interpreter, and logical control flow.

Substrate is designed to describe and run multi-inference workloads as fast as possible in a system that maximizes parallelism, throughput, and data locality. You'll get perfect parallelism, opportunistic batching, zero roundtrips, and near-instant communication between nodes – without writing any complex code.

The traditional alternative is to make a series of requests to multiple API providers. But the result is often slow, expensive, and fragile – due to unnecessary roundtrips and unoptimized program flow.
