## Executive Summary

Hirundo edits the weights of an already-trained AI model so it forgets specific things it learned, jailbreak weaknesses, memorized personal data, hallucination triggers, and bias, instead of retraining it. A Google DeepMind-hosted case study reports Hirundo's own result: hardening a Gemma model cut successful attacks by about three-quarters while keeping its benchmark scores. That result also names the threat, because the model providers Hirundo hardens could fold unlearning into their own training. Founders from the Technion give the team real academic standing, and Hirundo is an early entrant in a young discipline. It has no named paying customer and no proprietary dataset in the public record, so today the lead is being first, not being hard to copy.
