Substrate

Pricing is not something the Substrate team spells out here, so the clearest way to describe it is by what you build with it: Substrate is an AI developer platform for putting together compound AI systems, meaning workflows that chain several models and tools in one run.

You work through SDKs that bundle optimized AI models, vector storage, a code interpreter and agentic control flow.

Workflows are made by connecting modular building blocks called nodes, so a multi-step job becomes a graph rather than a pile of separate API calls.

Substrate is tuned for multi-step workloads, with automatic workload tuning, maximum parallelism and fewer roundtrips between steps.

That makes it most relevant if you are a developer assembling agents or pipelines and want one infrastructure layer to handle the plumbing.
