Open-source AntiFold onboarding manifest for antibody and nanobody inverse folding. It covers the Tamarind antibody/nanobody parameters for chains, antigen context, CDR/region selection, sampling temperature, batch count, and optional verification.
Configured minimum GPU memory.
After the last request a backend stays warm on its GPU for about 15 minutes, then frees the GPU. The next request triggers a fresh cold start.
POST to the native route with the shown model field; the playground below generates a full payload.

Copied snippets include gpu_type and region, so the first request targets this verified GPU and region. Remove those fields to let Forge choose another compatible target.

Model time uses the p50 warm model-reported execution time when available, then falls back to the latest probe time; p95/p99 and sample count appear when there is enough probe history. Cold start excludes the first (uncached) run. VRAM is the peak GPU memory seen during the probe. Relative compares each row's model time to the highlighted baseline (fastest row by default; hover any row to re-root). The fastest chip marks only verified supported GPU-region rows. Estimated on-demand GPU price (Nebius pay-as-you-go); shown for performance/price comparison. Configured minimum GPU memory: 16 GB.

Run a dedicated, autoscaling endpoint in your own Nebius account. The endpoint runs under your account and billing — Forge just pre-fills the configuration for you.
Opens the Nebius Console with the image pre-filled for AntiFold (Forge version latest).
Prefer to create the endpoint from the CLI, or self-manage the container image? Use the commands below.
The image is hosted on cr.eu-north1.nebius.cloud; you may need registry credentials in the Console form. The CLI below includes placeholders.
The links use Forge’s eu-north1 Nebius Container Registry mirror. If your project can’t pull that private mirror, add pull credentials or a registry secret.

# Note: the --image above points at Forge's regional Nebius CR mirror.
