Which one, for what

Berth B

Best for Someone running several GPU programs (llama.cpp, llama-swap, Ollama, vLLM, ComfyUI, games) on one NVIDIA card who wants them to take turns, and agents that need to ask for the card.

Ahead on

  • No incidents deducted, where GPT4All loses 6 points for them

Watch for

First released on 11 October 2026 and called alpha. Windows, AMD and multiple GPUs are experimental, and the gateway is a preview

GPT4All F

Best 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

Verdicts

Berth

Berth coordinates one NVIDIA card between engines, ComfyUI and games, grants a lease only after the driver shows memory free, and gives agents a skill, JSON output and a keyed loopback gateway. It is 17 days old, alpha and maintained by one developer, with Windows and AMD experimental and no machine-readable API spec.

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

Berth

  1. Run berth status --format json before starting, stopping or switching any GPU engine. If berthd is unreachable, no engine is protected
  2. Never kill a process to free VRAM. Ask for the card with berth run, berth hold or a gateway request, and report stowaways to the user
  3. Send gateway requests to http://127.0.0.1:9799/v1 with Authorization: Bearer $(berth key), and use "stream": true for cold starts of up to minutes
  4. On a 503, read the code and wait for Retry-After. A pinned holder (a game or berth hold) answers 409 to stop and is the user's call
  5. Ask the user before berth reclaim LEASE --yes, any berth.toml edit or berth update. Each changes the node

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

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
