Evidence boundaries
Organisation listings identify a reviewed canonical record. Model listings show an association in the source register; they do not by themselves establish model creation, current API availability, hosting location or infrastructure ownership.
Profile note
Open-source AI engineering platform for tracing, evaluation, prompt management and datasets. ClickHouse acquired Langfuse on 2026-01-16; the company says the same cloud endpoints continue and open-source/self-hosted licensing remains unchanged. Langfuse instruments applications but does not publish an owned foundation model.
