# Compatibility matrix

This page lists the exact versions Infera **0.1.0** has been validated against.
Everything here is what we have tested — combinations not listed are outside the
validated set for this release, not necessarily unsupported.

```{admonition} How to read this page
:class: note
Where a component is pinned to a specific image tag, use that exact artifact. The
validated engine images bundle the Infera connector, the `sitecustomize` hook,
and the RDMA transport shims on top of the vendor ROCm base — so the tag is the
tested unit, not just the engine version inside it.
```

## Engines

Infera orchestrates one or more engines. Install at least one. The 0.1.0 release
is validated against these engine versions and images.

| | vLLM | SGLang | ATOM |
| --- | --- | --- | --- |
| **Engine version** | 0.25.1 | 0.5.15.post1 | 0.1.4 |
| **Docker image** | `vllm/vllm-openai-rocm:v0.25.1` (ROCm base, digest-pinned) | `lmsysorg/sglang:v0.5.15.post1-rocm720-mi35x` | `rocm/atom:rocm7.2.4_ubuntu24.04_py3.12_pytorch_release_2.10.0_atom0.1.4_20260612` |
| **ROCm (image base)** | 7.2.3 | 7.2.0 | 7.2.4 |
| **OS (image base)** | Ubuntu 22.04.5 | Ubuntu 22.04.5 | Ubuntu 24.04.4 |
| **Python (image base)** | 3.12.13 | 3.10.12 | 3.12.3 |
| **PyTorch (image base)** | 2.11.0 | 2.9.1 | 2.10.0 |
| **Build date** | 2026-07-12 | 2026-07-15 | 2026-06-12 |

OS / Python / PyTorch above were read from inside each validated base image (not
the tag). See the platform table below for the baseline that applies across all
engines.

```{admonition} Engine images bundle more than the engine
:class: tip
The validated engine images layer the Infera connector, the `sitecustomize`
hook, and the Mooncake / ionic RDMA shims on top of the vendor ROCm base. For
serving, prefer the prebuilt image over a manual `pip install` of the engine.
See [Deployment → Engine images](../serving/deployment.md).
