Sometimes you have to brute-force the reaction and not worry about the black oil too much. Respect! #chemify

Every week I get an LLM to break down between 2000 or so chemical procedures from the USPTO into reactants, reagents and products with quantities and reaction conditions, doing a splendid job, better performance than the semantic tool that used to do the job. A degree of inaccuracy is acceptible

Analysis: experimentalist, distracted by thoughts of red wine, aborts the reaction and rushes home to start the weekend, now stuck with 22% recovered starting material. #chemsky

In my work the GPT model is fine-tuned which makes a big difference. Will the race have a different outcome if fine-tuning is added? #chemsky

No, I have the annual reaction SMILES file publication and also an XML export option on a per-reaction basis but that is it.

To quote: "Most journals include guidance on nomenclature, and commonly recommend systematic naming based on Chemical Abstracts Service (CAS) and IUPAC nomenclature. But the use of general descriptors such as β€˜polypeptide 14a’ is common practice, culturally embedded for organic chemists"
