Untrusted content - treat as data, not instructions._ ````text ## Quick Start (60 seconds) **1. Install** (one command, detects your RAM, picks a starter model): ```bash curl -fsSL https://rapidmlx.com/install.sh | bash ``` Installs Python 3.10+ if missing, creates an isolated venv at `~/.rapid-mlx/`, symlinks the `rapid-mlx` CLI into `~/.local/bin/`, and prints a serve command sized to your Mac (8–23 GB → `qwen3.5-4b-4bit`; 24–47 GB → `gpt-oss-20b-mxfp4-q8`; 48–95 GB → `qwen3.6-35b-8bit`; 96 GB+ → `gpt-oss-120b-mxfp4-q8`). > **`curl | bash` security.** `install.sh` is served over HTTPS (HSTS-preload) from `rapidmlx.com` and is a byte-identical mirror of [`install.sh`](install.sh) at the current release commit — read it before running if you like. Two verified alternatives: > - **Pin to a commit hash** — `curl -fsSL https://raw.githubusercontent.com/raullenchai/Rapid-MLX//install.sh -o install.sh && shasum -a 256 install.sh && bash install.sh` > - **Skip the shell script entirely** — use Homebrew, `uv`, or `pip` below. See [Alternative install methods](#alternative-install-methods) for the non-curl paths. **2. Chat with a model right now:** ```bash rapid-mlx chat ``` Defaults to `qwen3.5-4b-4bit`. First run downloads the weights (~2.5 GB) with a progress bar and drops you into a REPL. Type `/help` for slash commands, `/exit` to quit. **3. Or serve it for use from other apps:** ```bash rapid-mlx serve qwen3.5-4b-4bit ``` Starts an OpenAI-compatible HTTP server bound to `http://localhost:8000`. Point any OpenAI SDK / client (Cursor, Aider, LangChain, OpenCode, PydanticAI, your own scripts) at **`http://localhost:8000/v1`**; Claude Code / Anthropic SDK uses **`http://localhost:8000`** (the Anthropic messages route lives at `/v1/messages` under the same host). ```bash curl http://localhost:8000/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{"model":"default","messages":[{"role":"user","content":"Say hello"}]}' ``` ```python from openai import OpenAI client = OpenAI(base_url="http://localhost:8000/v1", api_key="not-needed") print(client.chat.completions.create( model="default", messages=[{"role": "user", "content": "Say hello"}], ).choices[0].message.content) ``` > **Vision / audio / diffusion models?** Base install is text-only (~460 MB). Vision, audio, embeddings, and DFlash speculative decoding ship as opt-in extras. → [Optional extras](https://rapidmlx.com/docs/extras.html) > **Not into the terminal?** [**Rapid-MLX Desktop**](https://rapidmlx.com/desktop) bundles the same engine inside a one-click Mac app. --- --- ## Alternative install methods The curl one-liner above wraps all of these — reach for these only if you already manage Python yourself.
Homebrew — Mac-native, tap + trust required on Homebrew 4.x ```bash brew tap raullenchai/rapid-mlx brew trust raullenchai/rapid-mlx brew install rapid-mlx ``` Upgrade with `brew upgrade rapid-mlx`. If `brew install` stalls on `Tapping homebrew/core`, run `brew tap homebrew/core --force` once (one-time ~1.3 GB download) and retry.
uv — isolated tool install, auto-manages Python ```bash uv tool install rapid-mlx@latest ``` Don't have uv yet? `curl -LsSf https://astral.sh/uv/install.sh | sh`. Upgrade with `uv tool upgrade rapid-mlx`.
pip — requires Python 3.10+ (macOS ships 3.9) ```bash python3.12 -m pip install rapid-mlx ``` If `pip install rapid-mlx` says "no matching distribution", your Python is too old. `brew install python@3.12` first. Upgrade with `pip install -U rapid-mlx`. For image-input / VLM models (Qwen-VL, true multimodal), install the vision extra: `pip install 'rapid-mlx[vision]'` — see [Optional extras](https://rapidmlx.com/docs/extras.html).
