Reliability through communication theory.
AgentCodec carries six primitives from communication theory into the LLM layer: diversity ensembling, hybrid ARQ, turbo decoding, rateless fountain codes, forward error correction, and adaptive coding and modulation. They generalize self-consistency, self-refine, and chain-of-verification — and outperform them on benchmark. SNR maps to task difficulty. Diversity order sets the slope of the failure-rate curve. Hallucination becomes a quantity you can budget against.
