Substrate Labs provides an API and developer SDKs for building modular, multi-inference AI workflows, optimizing how model outputs feed into other models. The platform harnesses curated open-source models across text, images, audio, and semantic vectors and emphasizes low-latency, high-parallelism execution. Its infrastructure includes colocated file and vector storage, a code interpreter, logical control flow, and tools to create “graph relations” between models. The company launched an API optimized for running ensembles of models to simplify complex AI pipelines into a few lines of code. Early customers include Substack and Maven, which have integrated Substrate for recommendations and creator-facing tools. Substrate announced an $8M seed round to accelerate development and adoption of its developer-first AI orchestration APIs.
