What is Substrate?
Substrate is a platform for building and running compound AI systems that orchestrates multiple models and data sources. It provides modular building blocks called nodes, which can be connected to create directed acyclic graph workflows that represent multi‑step AI tasks.
The engine automatically analyzes the graph to merge compatible nodes, reducing round‑trips and increasing parallelism. Integrated components include an optimized vector database for similarity search, a code interpreter for executing Python or TypeScript snippets, and a model router that selects the appropriate LLM for each step.
Developers can construct workflows in Python or TypeScript using a lightweight SDK, with futures to handle asynchronous execution. Substrate supports rapid prototyping and deployment of agentic AI applications, enabling teams to assemble complex inference pipelines without managing underlying compute infrastructure.
