Substrate

What is Substrate?

Substrate is a platform for building compound AI systems. It offers powerful SDKs with optimized AI models, vector storage, a code interpreter, and agentic control flow. It is designed as an infrastructure for intelligent software, providing simple abstractions for building complex workflows by connecting modular building blocks called nodes. Substrate is optimized for multi-step AI workloads, offering automatic workload tuning, maximum parallelism, and fewer roundtrips.

How to use Substrate?

Users can describe their tasks by connecting components (nodes) within the Substrate platform. The platform automatically optimizes the workflow as a directed acyclic graph, merging nodes that can be run in a batch. Substrate provides SDKs in Python and TypeScript for building compound AI systems.
