Overview
Raon-1 mini is a 30-billion-parameter mixture-of-experts language model developed by KRAFTON AI, trained from scratch. The publisher describes it as strong in Korean conversation and agentic tasks, with capabilities for instruction following, search, and tool calling. It is provided as a preview release and includes a DFlash2 draft for speculative decoding.
The released artifact is a 678-million-parameter DFlash2 draft model using the qwen3 type, stored in bfloat16 format. It supports a context window of up to 262,144 tokens. The model is licensed under Apache-2.0, allowing commercial use. Deployment requires handling the hybrid MoE layout, though no expert layers are present in this draft.

Memory
Parameter count multiplied by the bytes each format uses. The key-value cache comes on top.
| Precision | Weights | Notes |
|---|---|---|
| bf16 | 1.3 GiB | Full precision as released |
| fp8 | 0.6 GiB | 8-bit, near-lossless on most models |
| int4 | 0.3 GiB | 4-bit, smallest footprint |
The cache costs 12 KiB per token at 16-bit, so the full 262,144-token context of one request needs about 3.1 GiB. Concurrency multiplies that number, not the weights.
That figure is an upper bound: this model uses sliding-window attention with a 2,048-token window on some layers, so long requests cache less than this.
Hardware
At the released precision, with 90% of the card given to the server and 2.5 GiB kept for the runtime. The context column is what is left for the cache on that setup.

Serving

Questions
The weights take about 3 GiB at the released precision. That fits on one RTX 4090 24GB, which leaves roughly 17 GiB for the key-value cache.
The repository declares apache-2.0. Read the licence text before commercial use: the name alone does not tell you what is allowed.
The configuration allows 262,144 tokens. Whether the whole window is usable depends on the memory left for the cache, which the hardware table works out per card.
