What Substrate does
Substrate is a platform and SDK for building agentic AI and compound AI workloads. It provides batteries-included primitives, including language models, image generation, vector storage, and sandboxed code execution, so developers can describe multi-step AI computations and run them as connected workflows.
Key capabilities
- A workflow execution and inference engine optimized for multi-step AI workloads
- Built-in vector storage and a code interpreter alongside model inference
- Agentic control flow for connecting tasks into larger systems
- Automatic parallelization of inference calls to reduce roundtrips
- Support for multiple underlying models within one workflow
Who it's for
Substrate is aimed at developers and teams building AI systems such as RAG pipelines, agents, and multi-modal generative experiences. By offering high-performance components and elegant abstractions in one SDK, it suits engineers who want to compose complex, multi-call AI workflows without stitching together many separate services.
