Raon-1 mini (GGUF)

[!NOTE] This repository contains the GGUF files of Raon-1 mini preview for llama.cpp.

The GGUF files were converted from the BF16 weights of the same checkpoint. The main repository stores the routed experts in MXFP8. Q6_K and smaller were quantized with an importance matrix (imatrix).

Raon-1 mini is a 30B-A4B Mixture-of-Experts (MoE) language model, designed and trained from scratch by KRAFTON AI. It demonstrates strong capabilities in Korean conversation and agentic tasks. As part of the Raon open model family, it is released under the Apache 2.0 license.

Model Overview

Raon-1 mini uses a hybrid Mixture-of-Experts (MoE) architecture, consisting of 18 linear attention layers and 7 full attention layers.

Raon Delta Attention (RDA): Raon Delta Attention decouples the erase and write gates of Kimi Delta Attention, which improves long-context performance over KDA.
Raon-mHC: Raon-mHC reduces the computational cost of DeepSeek’s manifold-constrained hyper-connections (mHC), which speeds up training.
Hybrid layout: 18 of the 25 layers are Raon Delta Attention layers with a fixed-size state. Only the 7 MLA layers keep a KV cache, about 8 KiB per token in BF16.
Long context: Natively supports up to 262,144 tokens of context.
Sparse MoE: 6 of 128 routed experts plus 1 shared expert are active per token, so each token uses 4.3B of the 28.8B total parameters.

Speculative Decoding

We release a DFlash2 draft model alongside Raon-1 mini preview to accelerate inference through speculative decoding. In our benchmarks on a single NVIDIA B300, it delivers up to 2.18× higher output throughput than autoregressive decoding. Speedups vary by hardware and workload.

Throughput is measured in output tok/s, with speedup over autoregressive decoding in parentheses. Acceptance length (AL) is the mean number of tokens per verification step, averaged across requests at concurrency 1.

AR: autoregressive decoding; C: concurrency. Throughput is total output tokens divided by end-to-end wall time.
Evaluated with vLLM 0.28.0 and an MXFP8 target model; block size 8 (7 draft tokens), probabilistic draft sampling, temperature 1.0, top-p 0.95, top-k 20, thinking enabled, up to 4,096 new tokens, and 128 prompts per benchmark (80 for MT-Bench).

Quickstart

Raon-1 mini supports inference with Transformers, vLLM, llama.cpp, and MLX. The examples below show how to run the model locally or launch an OpenAI-compatible server, using thinking mode and the recommended sampling settings above.

The model repositories are gated. Request access once on this page (approval is automatic; it covers every Raon-1 mini preview repository), then log in so the examples below can download them:

Transformers

Use Hugging Face Transformers to load Raon-1 mini and generate responses directly in Python.

Install the dependencies:

Then run the model:

python

from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "KRAFTON/Raon-1-mini-preview"
tokenizer = AutoTokenizer.from_pretrained(    model_id,    trust_remote_code=True,)model = AutoModelForCausalLM.from_pretrained(    model_id,    dtype="auto",    device_map="auto",    trust_remote_code=True,)
messages = [    {"role": "user", "content": "Tell me about KRAFTON AI."}]inputs = tokenizer.apply_chat_template(    messages,    add_generation_prompt=True,    tokenize=True,    return_dict=True,    return_tensors="pt",    enable_thinking=True,    truncate_history_thinking=False,).to(model.device)
outputs = model.generate(    **inputs,    max_new_tokens=32768,    do_sample=True,    temperature=1.0,    top_p=0.95,    top_k=20,    min_p=0.0,    repetition_penalty=1.0,    presence_penalty=1.5,)
# The reasoning ends at </think>; the answer follows it.response = outputs[0][inputs["input_ids"].shape[-1]:].tolist()think_end = tokenizer.convert_tokens_to_ids("</think>")split = response.index(think_end) + 1 if think_end in response else 0reasoning = tokenizer.decode(response[:split], skip_special_tokens=True).strip()answer = tokenizer.decode(response[split:], skip_special_tokens=True).strip()print("Reasoning:\n" + reasoning)print("\nAnswer:\n" + answer)

presence_penalty is applied by the model's remote code, since Transformers has no built-in presence penalty. For coding and math, set presence_penalty to 0.0.

On a 32 GB GPU, use the base MXFP8 model with device_map="auto" and CPU offload.

vLLM (beta)

Use vLLM to serve Raon-1 mini through an OpenAI-compatible API with tool calling and DFlash2 speculative decoding. Tested on NVIDIA B300. The RTX 5090 NVFP4 profile is documented below.

Install from our fork and start the server:

bash

VLLM_REF="raon-1-mini-preview"
uv venv --python 3.12source .venv/bin/activate
VLLM_USE_PRECOMPILED=1 uv pip install \    "vllm @ git+https://github.com/krafton-ai/vllm.git@${VLLM_REF}"
vllm serve KRAFTON/Raon-1-mini-preview \    --host 127.0.0.1 \    --port 8000 \    --served-model-name Raon-1-mini-preview \    --max-model-len 262144 \    --max-num-batched-tokens 16384 \    --max-num-seqs 128 \    --gpu-memory-utilization 0.85 \    --kv-cache-dtype fp8_e4m3 \    --enable-prefix-caching \    --spec-method dflash \    --spec-model KRAFTON/Raon-1-mini-preview-dflash2 \    --spec-tokens 7 \    --reasoning-parser raon_1 \    --enable-auto-tool-choice \    --tool-call-parser raon_1 \    --default-chat-template-kwargs '{      "enable_thinking": true,      "truncate_history_thinking": false    }'

The first start compiles the model's kernels and takes about 10 minutes; later starts reuse them. To serve the NVFP4 checkpoint, replace the model with KRAFTON/Raon-1-mini-preview-nvfp4 in the same command. It runs on a single GPU (tensor parallel size 1).

RTX 5090 (32 GB)

Use the NVFP4 checkpoint with the following settings. CUDA Toolkit 13 with nvcc on PATH is required.

bash

# WSL2export VLLM_WSL2_ENABLE_PIN_MEMORY=1
vllm serve KRAFTON/Raon-1-mini-preview-nvfp4 \    --host 127.0.0.1 --port 8000 \    --served-model-name Raon-1-mini-preview \    --max-model-len 32768 \    --max-num-batched-tokens 2048 \    --max-num-seqs 8 \    --gpu-memory-utilization 0.85 \    --kv-cache-dtype fp8_e4m3 \    --kv-cache-memory 3221225472 \    --enable-prefix-caching --async-scheduling \    --spec-method dflash \    --spec-model KRAFTON/Raon-1-mini-preview-dflash2 \    --spec-tokens 7 \    --reasoning-parser raon_1 \    --enable-auto-tool-choice --tool-call-parser raon_1 \    --default-chat-template-kwargs '{"enable_thinking":true,"truncate_history_thinking":false}'

Use http://localhost:8000/v1 as the base URL and default_model as the model name. For coding and math, set presence_penalty to 0.

Agentic Use

Raon-1 mini preview can be used with agent harnesses such as Hermes Agent, Pi, and OpenCode through an OpenAI-compatible API. The examples below assume an endpoint at http://localhost:8000/v1 with the model ID Raon-1-mini-preview. Adjust these settings to match your server, ensuring that tool calling and reasoning are properly supported.

[!NOTE] With MLX, use KRAFTON/Raon-1-mini-preview-mlx as the model ID instead of Raon-1-mini-preview; mlx_lm server loads the model named in each request.

Hermes Agent

Hermes automatically detects the context window from the server when supported. If detection fails, add context_length: 262144 under model:. Replace dummy with your API key if the endpoint requires authentication.

Pi

json

{  "providers": {    "raon": {      "baseUrl": "http://localhost:8000/v1",      "api": "openai-completions",      "apiKey": "dummy",      "models": [        {          "id": "Raon-1-mini-preview",          "name": "Raon-1 mini preview",          "reasoning": true,          "contextWindow": 262144,          "maxTokens": 32768        }      ]    }  }}

Select the model using /model inside a session, or launch Pi with --model raon/Raon-1-mini-preview. Replace dummy with your API key if the endpoint requires authentication.

OpenCode

Register Raon-1 mini preview as a custom OpenAI-compatible provider in ~/.config/opencode/opencode.json (or opencode.json in your project root):

json

{  "$schema": "https://opencode.ai/config.json",  "provider": {    "raon": {      "npm": "@ai-sdk/openai-compatible",      "name": "Raon",      "options": {        "baseURL": "http://localhost:8000/v1"      },      "models": {        "Raon-1-mini-preview": {          "name": "Raon-1 mini preview",          "limit": {            "context": 262144,            "output": 32768          }        }      }    }  },  "model": "raon/Raon-1-mini-preview"}

The model field sets Raon-1 mini preview as the default model. You can also select it interactively using /models. If the endpoint requires authentication, configure an API key under options or use OpenCode's authentication settings.

For all three agent harnesses, the configured context window and maximum output tokens should not exceed the limits supported by the serving backend.

Access

Raon-1 mini preview is an open-weight model. Access is granted on request.

You can also try it in the Raon-1 mini playground, free for a limited time.
