Envariant is building the control layer for foundation models — an interpretability SDK that lets teams inspect, steer, and control model behavior.

Foundation models are powerful but volatile. They hallucinate, drift, and produce brittle outputs in complex domains where verification is too expensive, scarce, or ambiguous. Standard approaches are costly and destabilizing — leaving teams iterating on data instead of reasoning directly about model behavior.

Envariant moves verification upstream, directly into the model's latent space. The SDK exposes a compact set of primitives: detect and causally trace behaviors like hallucinations or invariant violations, reason inductively and steer outputs programmatically, extract human-readable principles, and synthesise targeted edge cases — no bespoke engineering required.

We're releasing SOTA results across safety, reasoning, and domain-specific evals soon.
