Raon 1 Nano — Hardware Requirements & GPU Compatibility

ChatFunctions

Raon-1 nano is a compact Korean and English instruction model from KRAFTON AI, released under Apache 2.0. It targets conversation, tool calling and deployment on local devices. Its hybrid architecture combines 18 linear-attention layers with six full-attention layers and supports a native context window of 262,144 tokens. KRAFTON reports 1.5 billion effective parameters and about 3.1 billion total parameters when the per-layer embedding tables are included; the distributed checkpoint also contains a small multi-token prediction module. The model was distilled from Raon-1 mini preview, then trained further and post-trained for conversational use. GGUF, MLX and LiteRT-LM versions are available for supported runtimes. Its emphasis on Korean and its custom architecture make runtime support worth checking before choosing a download.

4.1 GB VRAM at 16K context · fits the RTX 4090 (19.9 GB free)

Works on macOS, Windows and Linux.

Install Ollama (Linux)
$curl -fsSL https://ollama.com/install.sh | sh
Install Ollama (macOS / Windows)
Download and run the app; it installs the ollama command.
Download Ollama ↗
Run Q4_K_M
$ollama run hf.co/KRAFTON/Raon-1-nano-gguf:Q4_K_M
Raise the context window
Type it inside the chat. For the API server instead, start it with OLLAMA_CONTEXT_LENGTH=16384 ollama serve.
$/set parameter num_ctx 16384
A larger context needs more memory than the weights alone.
Use the API
Ollama serves its API on http://localhost:11434.

Works on macOS, Windows and Linux.

Install LM Studio
Desktop app for macOS (Apple silicon), Windows and Linux.
lmstudio.ai ↗
Download the model
In the app press Ctrl/Cmd + Shift + M and paste https://huggingface.co/KRAFTON/Raon-1-nano-gguf, then pick Q4_K_M. Or use the CLI (run LM Studio once first):
$lms get https://huggingface.co/KRAFTON/Raon-1-nano-gguf@Q4_K_M
Open on Hugging Face ↗
Load and chat
Open the model loader, select the model and set Context Length to 16384. Leave GPU offload at maximum if it fits.
Start the local server (optional)
$lms server start

Works on macOS, Windows and Linux.

Install llama.cpp (macOS)
MacPorts, Nix and conda-forge also work.
$brew install llama.cpp
Install options ↗
Install llama.cpp (Windows)
$winget install llama.cpp
Install llama.cpp (Linux)
Download the prebuilt llama-*-bin-ubuntu-* archive for your GPU backend (CPU, Vulkan) from the releases page, unpack it and run the binaries from that folder. Homebrew (brew install llama.cpp) and conda-forge also work on Linux.

Frequently Asked Questions

How much VRAM does Raon 1 Nano need?

Raon 1 Nano requires 2.1 GB of VRAM at Q4_K_M, or 7.0 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 3.2B × 4.8 bits ÷ 8 = 1.9 GB

KV Cache + Overhead ≈ 0.2 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

Can I run Raon 1 Nano on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Raon 1 Nano. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 2.1 GB of usable unified memory (RAM minus macOS overhead).

Can I run Raon 1 Nano locally?

Yes — Raon 1 Nano can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Raon 1 Nano?

At Q4_K_M, Raon 1 Nano can reach ~2275 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~311 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 2.1100 × 0.65 = ~2464 tok/s
