Hirundo

Hirundo is an AI company specializing in machine unlearning — enabling organizations to selectively remove knowledge, data, or behaviors from trained models without full retraining.

We build tools and infrastructure for teams that need precise control over what their models know: for compliance, privacy, safety, and model lifecycle management.

What you'll find here

• Research artifacts and benchmarks for machine unlearning
• Fine-tuned and selectively unlearned model checkpoints
• Datasets and evaluation suites for forget/retain performance
