How Athanor's chemistry predictions work
Predictions come from arbastro's own chemistry models, served by arbastro on its own server and listed in Settings › AI. Each prediction shows its confidence and is never presented as a measured fact.
The models
Settings › AI lists the arbastro chemistry models in use under arbastro chemistry models.
They are served by arbastro on its own server. A feature uses its model while that model is listed, and the AI model chosen above it in Settings otherwise.
| Model | Used for |
|---|---|
| Athanor Productum | Predicting the products of a reaction |
| Athanor Resolvere and Texere | Retrosynthesis routes and precursors |
| Athanor Motus | Building a mechanism |
| Athanor Scriptum | Reading handwriting |
| Athanor Cernere | Reading structures from a picture |
| Athanor Resonantia | Predicting NMR spectra |
How a prediction is shown
- Every predicted value carries its confidence or its range, and says it is predicted. See NMR accuracy for how the NMR ranges are measured.
- A prediction is never presented as a measured fact, and nothing predicted replaces what you drew without you choosing it.
- Every structure a model proposes passes the safety screen first.
What is sent
Product prediction and routes send the structures and conditions you drew to arbastro's chemistry service, only while you are signed in. It keeps nothing about a request beyond its method, path, status and time. See the privacy policy.
