Expert Systems in The Age of Reasoning
Hallucination-free by design.
Give a deterministic engine the same interface as an LLM and the experience is indistinguishable, tool calls, streaming output, a full reasoning trace. What changes: 10–100× faster. Structurally incapable of hallucinating.
LLM costs rise with every call. Deterministic agents output instantly, no per-token charges, no latency spikes, no budget surprises. At production scale, that gap is measured in orders of magnitude.
All our agents are open-source, readable, forkable, and annotatable. The SDK handles structured tool dispatch, streaming output, typed I/O, and reproducible traces. You bring the domain logic.
