01Binder formats + scientific methods

Science, not secret sauce.

Choose the binder format that fits the biology, then run a leading scientific method built for it—from antibody fragments and de novo miniproteins to linear, cyclic, and stapled peptides.

Start with a target structure, define the interactions that matter, and run the original methods through guided interfaces. The controls stay visible, and structures, scores, and intermediate designs stay organized.

Antibody-derived: Fab · scFv · VHH / nanobody
Protein binders: Large binders · miniproteins · ankyrin repeat
Peptides: Linear · cyclic · stapled α-helical / helicon

02Guided workflow

Design the binder your program needs.

Work on the website, delegate to your agent, or move between both. Your settings, progress, structures, and results stay connected to the same project.

Start with the structure

Prepare the biology that matters.

Upload a structure or find one through RCSB, choose the relevant chains and residues, and inspect the target before starting a design campaign.

Stay close to the run

See each stage as it progresses.

Follow backbone generation, sequence design, structure prediction, analysis, and filtering from one project view as each stage advances.

Keep the outputs organized

Move from a run to ranked designs.

Review final and intermediate designs, download the files you need, and keep every project connected to its settings and outputs.

03Work with your agent

Bring your agent into the experiment.

Give Claude Code, Codex, or your preferred coding agent access to your Ariax projects. You can ask it to prepare a campaign or dig into results from a run you started on the website.

The Ariax CLI includes scientific guides for each engine so your agent can explain its choices as it works. Review the proposed experiment before authorizing compute, then open the project in your browser whenever you want to inspect a structure yourself.

Set up your agent

Example: receptor-blocking VHHs

You ask

“Use BindCraft2 on Ariax to design VHHs that block my protein’s interaction with its receptor. Start from a suitable structure in the Protein Data Bank.”

A pilot you can approve

Your agent checks the binding interface and assembles the design inputs. It proposes settings and a GPU budget, then waits for your approval to launch.

Once connected, your agent can also find and work with your existing Ariax projects.

04On-demand GPUs

Enterprise GPUs on demand.

Run modern binder-design campaigns without waiting for a shared cluster queue or requesting a larger quota.

Launch one binder design or ten immediately. Ariax runs each campaign on modern NVIDIA GPUs and charges only for the GPU compute it uses—no platform subscription or quota approval required.

GPU availability varies by workflow and changes with demand; some GPU types are easier to provision than others.
