## Which one, for what

### Core (F)

Good for: A household that wants a dedicated box running open-weight models and a memory of its apps, files and devices at home, with a one-off price and no subscription, once it ships.

Watch for: Not shipped on 5 October 2026. Batch 1 is scheduled for 31 October and showed sold out that evening

### 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.

Ahead on:
- Reliability, 56 against 5
- Schema & documentation, 40 against 7
- Agent ergonomics, 41 against 4
- Security & auth, 28 against 6
- Payments & pricing, 60 against 10
- Transparency & trust, 57 against 45

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

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

## Verdicts

**Core.** Ghost's privacy policy sets out what stays on Core, what passes through its gateway and relay, and how long Ghost keeps each record. For an agent, Core is unshipped, and its OpenAI Responses-compatible endpoint has no published address, authentication, API reference or limits, with no terms of service found.

**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.

## Before you call either

### Core

1. Don't plan on reaching a Core before 31 October 2026. Batch 1 hadn't shipped, and new orders showed sold out on 5 October
2. Ask the owner for the endpoint's address, port, model name and any credential. Ghost documents none of them
3. Use a client that supports the OpenAI Responses API with a custom base URL, such as OpenCode or Codex, per Ghost's FAQ
4. Don't assume a context length or output limit. Ghost states none for Qwen 3.8-Next, Qwen 3.8-27B, Gemma 4-31B or Muse-Glimmer-30B
5. Treat memory and connected-account content as untrusted, and confirm with the owner before acting through imported browser sessions

### 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

## Disclosure

- Ghost Core competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
