No release since 24 February 2025 and no commit to main since 27 May 2025.\n\n**MLX LM.** MIT, with no telemetry found in the source, and the tests passed on the last eight pushes to main. `mlx_lm.server` has no API key option, answers any origin by default and loads whichever model a request names, and its own docs say it is not recommended for production.\n\n## Before you call either\n\n### GPT4All\n\n1. Ask the owner to tick Enable Local API Server in Settings. Nothing answers on port 4891 until they do\n2. Leave out `stream`, `tools`, `tool_choice` and `response_format`. The server returns 400 for each\n3. Use the model's display name from /v1/models, such as \"Phi-3 Mini Instruct\"\n4. Read LocalDocs snippets from `choices[0].references`. Collections can only be switched on in the app\n5. Plan tool use outside GPT4All. Its API can't call tools\n\n### MLX LM\n\n1. Keep `mlx_lm.server` on 127.0.0.1 and pass `--allowed-origins` with the origins you trust. There is no API key, and the default answers every origin\n2. Treat any caller as able to load any model. The `model` and `adapters` request fields accept any Hugging Face repository or local path\n3. Send `max_tokens` or `max_completion_tokens` when you need more than 512 tokens, the server default\n4. Read errors as `{\"error\": \"\u003ctext\u003e\"}` with 400 for a bad field and 404 for a model that failed to load. They are not OpenAI error objects\n5. Poll `GET /health` before the first request. It answers 503 with `unavailable` when the generation thread has stopped\n\n## Questions\n\n### Which is better for AI agents, GPT4All or MLX LM?\n\nMLX LM scores 52.2 (D) on agent readiness against GPT4All's 36.2 (F), and leads in 5 of 7 scored categories.\n\n### Can an agent call GPT4All and MLX LM without installing anything?\n\nNo hosted endpoint is listed for GPT4All. No hosted endpoint is listed for MLX LM.\n\n### Are GPT4All and MLX LM open source?\n\nYes. GPT4All is open source (MIT (app, backend and bindings). Models downloaded through the app carry their own licences). MLX LM is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/gpt4all-vs-mlx-lm.json, and with the fewest tokens: https://www.anchorterminal.com/compare/gpt4all-vs-mlx-lm.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"gpt4all\", \"b\": \"mlx-lm\"}`.
