micro1 launched flow-transform 1.0, a PII transformation model claiming frontier-level performance in detection, identity synthesis, and transformation of personally identifiable information.
Key points:
- Reaches 96.0% F1 on PrivacyBench, beating baselines including Tonic Textual, Claude Opus 4.8, Sonnet 4.6, Microsoft Presidio, Haiku 4.5, and GLiNER2
- Thesis: enterprise operational data is gold for training frontier models but riddled with PII; traditional redaction destroys the workflows models need to learn
- flow-transform transforms rather than deletes PII, preserving business structure
