Sophea AI · KIEFER SA

KIEFER SA’s proprietary speech systems and adaptations, including a hosted ASR K1 preview. Separately released open-weight language, retrieval, speech and robotics families are excluded from this closed-weight catalog.

October and September ASR K1 revisions, three paper-identified internal shipped model families and one research ensemble reviewed. Public API availability is limited to the current preview; internal artifacts and illustrative product names remain unresolved.
