## Verdicts

**llama.cpp.** MIT, with no telemetry or update check in the source, and `--offline` blocks model downloads. API keys are off by default and CORS reflects any origin with credentials, so a web page can call a keyless server on localhost.

**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

### llama.cpp

1. Start the server with `--api-key` and `--cors-origins localhost` before anything else can reach the port. Both are off by default
2. Pass `n_predict` or `max_tokens`. Generation is unbounded by default
3. Send `response_fields` to /completion to drop the fields you don't read
4. Wait and retry on a 503 `unavailable_error`. The model is still loading
5. Read the server README of the build you run. Behaviour changes between nightly builds without a changelog entry

### 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
