Torch Spyre has integrated with PyTorch’s Cross‑Repository CI Relay (CRCR) at level 2. The project added an agentic pipeline that automatically picks relevant tests from PyTorch’s tens of thousands of tests and generates a declarative YAML file to adapt them without patching upstream code. This lets the IBM Spyre accelerator run only the tests that matter for its hardware while keeping the selection up‑to‑date as PyTorch evolves.

## The facts

- Torch Spyre achieved L2 CRCR integration.
- The pipeline selects and re‑buckets tests from a test suite of tens of thousands.

## Why it matters

It lets accelerator developers test their hardware efficiently and stay compatible with fast‑moving PyTorch releases.
