Provenance and accuracy

Research outputs carry their sources, and every step of the trail can be inspected, across the whole product.

The paper audits its own claims

Appendix A of the Lacuna preprint is a per-claim audit table: each extracted claim, paired with the evidence that supports it. The statuses include "Supported," "Supported (limitation)," and, in one row, "False (useful failure case)."

On being wrong

Systems built on language models can be wrong, this one included. The design response is inspectability everywhere, plus measurement in public. We benchmark our own stack in a preprint (arXiv:2606.26246 (opens in new tab)), and the numbers include the unflattering ones: on survey-grade citation, the best F1 in the test, Lacuna's own, is 0.052 against GPT-Researcher's 0.039. Better than the alternative and nowhere near solved, and published anyway. That is the standard this product wants to be held to.
