Substrate

Building sophisticated AI systems often means cobbling together different tools, managing dependencies, and fighting infrastructure just to get your workflow running. Substrate is a platform built to make compound AI systems actually enjoyable to build. It offers powerful SDKs with optimized AI models, vector storage, a built-in code interpreter, and agentic control flow — all organized around modular building blocks called nodes that snap together into clean, complex workflows. Designed specifically for multi-step AI workloads, Substrate provides automatic workload tuning, maximum parallelism, and fewer roundtrips — so your AI pipelines run faster and your engineering team focuses on building, not plumbing.
