Research
Where the method came from.
Before Vinci, we built the flash-1 series — open research models that taught us how to train toward a Constitution. They're open on Hugging Face, kept here as research, not as the product line.

Open research models.
Released under Apache 2.0 — useful, honest about their tradeoffs, and the groundwork for Constitutional Fine-Tuning.
