## Which one, for what

### Docker Model Runner (C)

Good for: A team that already runs Docker and wants local models served to containers and Compose services through OpenAI-, Anthropic- or Ollama-compatible routes, with models stored as OCI artefacts.

Ahead on:
- Transparency & trust, 73 against 47

Also in its favour:
- No key needed to call it

Watch for: No credential on the API. The docs say any client that can reach it, including other containers, can pull, load and run models

### LocalAI (B)

Good for: An owner who wants one local server for chat, embeddings, reranking, speech, images and video behind APIs their existing OpenAI, Anthropic or Ollama clients already speak, on almost any accelerator.

Ahead on:
- Schema & documentation, 81 against 49
- Agent ergonomics, 71 against 58
- Security & auth, 62 against 40
- Maintenance & community, 80 against 55

Also in its favour:
- Runs on your own machine

Watch for: No authentication by default. Loopback, LAN and VPN binds answer every caller, and keys set by environment variable grant full admin

## Verdicts

**Docker Model Runner.** CI passes on the main branch, and Docker has published two security advisories with CVEs and fixed versions for the project. The API takes no credential, so any client or container that reaches it can pull, delete and run models, and the documentation has no OpenAPI file or error reference.

**LocalAI.** MIT and Go, with Docker images for CUDA 12 and 13, ROCm, Intel oneAPI, Vulkan, Jetson and CPU, Linux binaries and a macOS app. No authentication by default. Loopback, LAN and VPN binds answer every caller, and keys set by environment variable grant full admin.

## Before you call either

### Docker Model Runner

1. Use base URL `http://localhost:12434/engines/v1` for OpenAI clients and `http://localhost:12434` for Anthropic and Ollama clients. Any API key value is accepted
2. In Docker Desktop, run `docker desktop enable model-runner --tcp 12434` first. Host-side TCP is off by default
3. From a container, call `http://model-runner.docker.internal` on Docker Desktop or `http://172.17.0.1:12434` on Docker Engine
4. Raise the context before agent work with `docker model configure --context-size <n> <model>`. The llama.cpp default is 4,096 tokens
5. Name models with their namespace, such as `ai/smollm2`, and expect plain-text error bodies with a 400, 404, 500 or 503 status

### LocalAI

1. Send `Authorization: Bearer <key>` when the operator has set keys. A 401 means the instance has auth on
2. Read /.well-known/localai.json and /api/instructions first. Both answer without a key and list what this instance can do
3. Back off on 429 and 503 for the Retry-After seconds. A 503 can mean the model is still loading
4. Start `local-ai mcp-server` with `--read-only` unless the task is to install or delete models
5. Take model names from /v1/models. Each instance names its own
