KoboldCpp scores 60.5 (C) on agent readiness against Core's 7.3 (F), and leads in every scored category. Both do local inference.

- Core: grade F, 7.3/100, rank #842 of 842. Markdown https://www.anchorterminal.com/tools/ghost-core.md · JSON https://www.anchorterminal.com/api/v1/tools/ghost-core.json

## 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

### KoboldCpp (C)

Good for: An owner who wants text, image, speech and music models behind one executable with a writing and roleplay interface, and clients that speak the KoboldAI, OpenAI, Ollama or Anthropic formats.

Ahead on:
- Reliability, 68 against 5
- Schema & documentation, 68 against 7
- Agent ergonomics, 63 against 4
- Security & auth, 38 against 6
- Payments & pricing, 60 against 10
- Maintenance & community, 82 against 3

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

Watch for: With no `--host` the server accepts connections on all routable interfaces, and no password is set by default

## 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.

**KoboldCpp.** One file runs text, image, speech and music models behind a published OpenAPI 3.0.3 document, with eight releases in 90 days. The server listens on every interface with no password by default, and `--password` leaves the image routes open.

## 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

### KoboldCpp

1. Start with `--host 127.0.0.1` and `--password`. The default listens on every interface with no key
2. Send the password as `Authorization: Bearer <password>`. It is not read from the query string
3. Treat 503 as both busy and rate limited. The server never sends 429 or `Retry-After`, and the wait in seconds is in `detail.msg`
4. Pass `max_length` or `max_tokens`. The default is 2,048 tokens unless `--defaultgenamt` changes it
5. Send a `genkey` with each generation so `/api/extra/generate/check` and `/api/extra/abort` act on your request and not another caller's

## 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.
