## Which one, for what

### GPT4All (F)

Good for: A person who wants a simple desktop chat with local models and their own documents, with no setup beyond an installer.

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

Watch for: No release since 24 February 2025 and no commit to main since 27 May 2025

### Lemonade (B)

Good for: An owner with AMD hardware (Ryzen AI NPUs, Radeon or Strix Halo) who wants one local server for chat, speech and images that existing OpenAI, Anthropic or Ollama clients can call, and for MCP clients that want local models as tools.

Ahead on:
- Reliability, 75 against 56
- Schema & documentation, 70 against 40
- Agent ergonomics, 70 against 41
- Security & auth, 36 against 28
- Maintenance & community, 76 against 6
- Transparency & trust, 64 against 56

Also in its favour:
- No incidents deducted, where GPT4All loses 6 points for them

Watch for: No authentication by default. With no key set, every route answers, including `/internal/*` shutdown and configuration

## Verdicts

**GPT4All.** MIT, with installers for Windows x64 and ARM64, macOS 12.6 or later and Linux, and published minimum and recommended hardware. No release since 24 February 2025 and no commit to main since 27 May 2025.

**Lemonade.** Apache 2.0, with weekly releases, installers for Windows, macOS and five Linux routes, and a six-tool MCP endpoint whose descriptions steer a caller away from accidental multi-gigabyte downloads. Authentication is off by default, the repository has no security policy, and the docs tell WebSocket clients to pass the key in the URL.

## Before you call either

### GPT4All

1. Ask the owner to tick Enable Local API Server in Settings. Nothing answers on port 4891 until they do
2. Leave out `stream`, `tools`, `tool_choice` and `response_format`. The server returns 400 for each
3. Use the model's display name from /v1/models, such as "Phi-3 Mini Instruct"
4. Read LocalDocs snippets from `choices[0].references`. Collections can only be switched on in the app
5. Plan tool use outside GPT4All. Its API can't call tools

### Lemonade

1. Call `lemonade_list_models` (or `GET /v1/models`) before naming a model. A wrong name with `allow_download: true` can start a multi-gigabyte download
2. Send `Authorization: Bearer <key>` when the operator has set `LEMONADE_API_KEY`. `/internal/*` needs the admin key when one is set
3. Use `POST /v1/chat/completions` for streamed tokens, embeddings and speech. The MCP endpoint ignores `stream` and has no embeddings or text-to-speech tool
4. Pass `output_dir` to `lemonade_generate_image` and `lemonade_omni` to get file paths in place of inline base64. Writes stay inside the MCP media sandbox
5. Read `GET /v1/docs` on the running server for the reference that matches its version. Weekly releases change behaviour
