Core Frameworks
One stack. Five primitives.
Each repository solves one hard problem in the agentic stack — composable, independently deployable, MIT-licensed.
agentdeploy
/ DeployDeterministic deployment runtime for agentic workflows with integrated state recovery, versioning, and rollback.
promptops
/ OpsCI/CD for large language model prompts. Automated regression testing and semantic versioning for context.
evalforge
/ EvalSynthetic data generation and objective evaluation suites for complex multi-step reasoning chains.
guardrailgraph
/ SafetyReal-time policy enforcement for LLM inputs and outputs using graph-based validation primitives.
lambdallm
/ EdgeCold-start optimized inference engine for serverless LLM execution in edge environments.
Technical Leadership
Architecture as the foundation of impact.
In the next decade, software will not be written manually — it will be orchestrated. Substrai was founded on the premise that if LLMs are the engine, the industry still lacks the chassis and the transmission.
The work here focuses on building the deterministic layers that allow probabilistic models to function safely in critical systems — formal verification, type-safe policy graphs, and reproducible runtime environments.
Open source is not just a distribution model. It is a governance strategy. By building Substrai in the open, we establish a standard for how autonomous systems should be deployed, audited, and secured.
