Free-energy perturbation (FEP)

Compute relative binding-free-energy differences between two ligands. The gold-standard quantitative step in lead optimisation — ranks closely related candidates without re-running docking.

We use this to filter candidate devices. We divide by the typical run count for this workload — you can override that under Advanced.

'Regulated' triggers automatic decision-record + bilingual PDF + ZIP bundle.

Free text — rides into the decision record so audits can grep your reference (e.g. "AAPL Dec 2026 $200 call").

Sign in to run — free tier is 500/month, shared with the qlro CLI on the same key.

The same circuit shape and ranking are produced by qlro.recommend_workload("industry.pharma.free_energy_perturbation") in the Python SDK — useful if you want to automate this in CI / CD.
