Credits

Credits are deducted from your workspace balance each time you run a tool. The exact cost is shown on the Run button before you submit — there are no usage-based billing surprises.

Jobs and credits

Jobs and credits are two separate limits.

A job is a single tool run. Your plan controls how many jobs you can submit per day. The free plan allows up to 3 jobs per day. All paid plans have no daily limit.

Credits are your monthly compute budget. Even with no daily job limit, you can only spend as many credits as your plan includes. Each tool shows its credit cost before you run it. Format converters and simple utilities cost 0 credits. Compute-heavy tools cost 3–250 credits depending on the tool and input size.

These two limits are independent:

• Run free converter tools as many times as you want — they never consume credits.
• Run compute tools up to the limit your monthly credit balance allows.
• "No daily limit" removes the daily submission cap. It does not mean unlimited compute.

For example: a Starter plan gives you 2,000 credits per month and no daily job cap. You could run 200 format conversions in a day for free, or run roughly 40 structure prediction jobs at 50 credits each before the monthly balance runs out.

How costs are calculated

Three factors determine what a job costs:

• 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.

Checking your balance

To view your remaining credits and usage history:

1. Click your profile in the bottom-left sidebar
2. Select Usage

Hovering over any Run button shows a tooltip with the job cost and your current balance.

When jobs fail

Credits are refunded automatically when:

• A job fails due to a platform or system error
• A job is canceled before processing starts

Jobs that fail because of invalid input or user error are not refunded. Check job history to confirm whether a refund was applied.

If credits were not refunded when they should have been, contact us.

Monthly allowances

Each plan includes a fixed number of credits per billing cycle. Credits reset at the start of each cycle and unused credits do not roll over. On per-seat plans (Lab and Teams), the monthly allowance scales with seat count and is shared across the workspace.
