Email key-line bolding
A 270M-parameter Gemma 3 fine-tune that puts the key parts of an email in bold (the requests, the purpose, the main points, the key facts) and changes nothing else. Built for dictation pipelines, where it runs after a paragraph-breaks model. Two other ways to use it:
- Outbound: an AI agent drafting an email bolds the details so the recipient finds them at a glance.
- Inbound: mark up the emails you receive. The model only marks spans; a mail client could show them as highlights instead of bold. Pick Inbound below to see that.
Preliminary model (2026-10-21): word F1 0.62 on six held-out emails, precise but tends to under-bold. The examples are held-out synthetic emails the model never saw. Runs on CPU, so allow 20-60 seconds.
