The speaker's team began an internal supervised fine-tuning project around the previous summer to teach language models SMILES, because existing frontier models performed poorly at understanding SMILES.

“... right, right. It does, it does kind of look like that, and that's kind of why we made it like that. And then, I think one thing I mentioned earlier that has been very interesting to us is about this time last summer, we had started an internal project to do, uh, supervised fine-tuning on some of these language models to get them to understand SMILES, because none of the existing frontier models were any good at it.”
