## Description

Pick the right serving container for a SageMaker model deployment and find its current image URI. Use this skill whenever about to deploy a model to a SageMaker endpoint and an image URI needs to be chosen, including when the user says "deploy this LLM", "host this HuggingFace model", "serve this fine-tuned model", "deploy this embedding model", "host a reranker", "serve a sentence-transformers model", or when about to hardcode any container URI in deployment code. HuggingFace-curated Deep Learning Containers are ALWAYS preferred: HuggingFace vLLM (LLMs and generative rerankers), HuggingFace vLLM-Omni (multimodal), TEI (embeddings/cross-encoder rerankers), HF Inference Toolkit (other transformers). Generic images (AWS vLLM, DJL-LMI, SGLang) are used only when no HuggingFace image is compatible, never merely because they carry a newer version. Never hardcode a container URI from memory and never default to TGI. Prevents stale-image failures and wrong-region URIs.

# Serving Image Selection

The serving container is the single thing most likely to break a SageMaker deployment that "looked correct on paper". Wrong container, stale tag, or the wrong AMI, all produce the same opaque `Failed to pass health check` error.

## Rule zero: HuggingFace images always win

When both a HuggingFace-curated family (`huggingface-vllm`, `huggingface-vllm-omni`, `huggingface-sglang`, `tei`, `huggingface-pytorch-inference`) and a generic family (`vllm`, `vllm-omni`, `sglang`, `djl-inference`) can serve the model, **the HuggingFace one is mandatory, not preferred**. The only valid reasons to use a generic image:

1. **Verified incompatibility**, the model needs an architecture/modality/feature no available HuggingFace tag supports, confirmed against the catalog (not assumed).
2. **No HuggingFace tag exists in the target region** and mirroring is not an option.
3. **The HuggingFace image is in "Known-broken images"** below.

A **newer version number on the generic repo is not a reason**. The AWS `vllm` repo often publishes a higher vLLM version than `huggingface-vllm`; an older-but-compatible `huggingface-vllm` tag still wins. "Latest vLLM" is not a requirement anyone stated, compatibility with the model is. If you fall back, record in the deployment log which of the three reasons applied.

## Where image URIs come from

**Primary source: AWS's official Deep Learning Containers catalog.**

URL: https://aws.github.io/deep-learning-containers/reference/available_images/

This page is AWS-maintained and lists every image family with example URIs, tags, CUDA versions, Python versions, and platform (SageMaker vs EC2/ECS/EKS). When picking a URI for a deployment, **read it from this page directly**, copy the example URL, substitute `<region>` with the user's region, and pass it to `deploy.py --image-uri`.
