# Set up AtlasFold as a remote tool

> Validation status (2026-10-01): AtlasFold v1.0.0 ran on the NVIDIA GB10 (aarch64, cc 12.1) under the optimization kit's `big` mode with **thirteen levers ablated and upstream's triangle backend forced to `torch`**. Both were necessary. This stack's triton 3.3.1 cannot compile a warp-shuffle kernel for this card -- it aborts the process with `LLVM ERROR: Cannot select`, which no worker can catch -- and a newer `ptxas` does not help, because the failure is upstream of ptxas. Verified on twelve requests in held workers including 600- and 800-residue folds. Peak reserved 12.06 GiB at 100 residues, 19.64 at 600, 38.63 at 800. **Read three warnings before deploying this one.** (1) A 35-residue smoke exercises NONE of the kit's kernel levers -- they are all gated at 512 tokens -- so a green smoke here would have been the most misleading result this provider could produce; the acceptance test must reach the largest input you will accept. (2) Stock AtlasFold under its own default `--kernel auto` cannot fold past about 128 tokens on this card at all, kit or no kit, because cuEquivariance ships its own Triton kernels; `--kernel torch` is the only backend that answers here. (3) The VRAM reserve RATCHETS: after one 800-residue fold the worker reports 38.63 GiB for every later request including a 3-second one, because the caching allocator keeps the segments it grew. A deployment capped at 400 residues holds this provider in 14 GiB rather than 39. Public publication, cross-user isolation, concurrency, recovery and structural accuracy are untested; keep this deployment private.

## Prerequisites

- Run from the ToolUniverse repository root on Linux with Python 3.12.3.
- A CUDA GPU is required. This provider holds its model resident between requests; CPU is not a target.
- Keep provider data, weights, caches, and credentials outside Git.
- Bind to loopback. A non-loopback bind requires TOOLUNIVERSE_API_TOKEN; never put it in arguments or results.
