Credits

How pricing works

We calculate costs upfront. You see the exact credit cost on the Run button before you submit. No usage-based billing surprises.

What affects cost:

• Tool type: Format converters are free. Analysis tools cost 3–20 credits. ML models cost 50–250 credits.
• Input size: Longer sequences, larger structures, and more molecules increase cost.
• Compute resources: GPU-based tools cost more than CPU tools.

Cost scales predictably. A 200-residue protein costs less to fold than a 500-residue protein. Docking 10 ligands costs less than docking 100.

Credit costs by category

• Free (0 credits): Format converters and simple utilities. PDB to FASTA, GenBank to FASTA, DNA to RNA, and all other converters run free.
• Analysis (3–20 credits): Sequence analysis and property calculations. Includes ADMET-AI, Clustal Omega, MAFFT, HMMER, and IgBLAST. Cost scales with number of sequences.
• Inverse folding (20–50 credits): Sequence design from structures. ProteinMPNN, LigandMPNN, ESM-IF1, AntiFold, and IgDesign.
• Structure prediction (50–100 credits): Protein folding models. ESMFold, AlphaFold2, Chai-1, Boltz-2, and OpenFold 3. Cost scales with sequence length.
• Docking (50–100+ credits): Protein-ligand and protein-protein docking. AutoDock Vina, GNINA, DiffDock, HADDOCK3, and DynamicBind. Cost depends on ligand library size.
• Design (100–250 credits): De novo protein and antibody design. RFdiffusion, BindCraft, BoltzGen, IgGM, and EvoPro. Cost scales with design complexity.
• Simulation (50–150 credits): Molecular dynamics and binding analysis. AlphaFlow, gmx_MMPBSA, and MD Trajectory Analysis.

Each tool shows its exact cost before you run it.
