# Super Kaiju by RMDW

Super Kaiju is RMDW's frontier-size private coding model, served from RMDW's own hardware as an OpenAI-compatible API. It is the big sibling to [Kaiju-Coder](https://huggingface.co/RMDWLLC/kaiju-coder-mlx-1.0): where Kaiju-Coder is the fast, local, fine-tuned builder model, Super Kaiju is a frontier-size open coder run across a two-machine Apple Silicon cluster for the work that wants the biggest model you can self-host.

## What it is, honestly

Super Kaiju is **Qwen3-Coder-480B-A35B-Instruct** (a 480B-parameter, 35B-active mixture-of-experts coder, Apache-2.0) served at 4-bit through MLX, **pipeline-parallel across two Apple M3 Ultra Mac Studios** wired together over Thunderbolt with RDMA. It is wrapped in RMDW's Kaiju harness and system identity and exposed as a drop-in OpenAI-compatible endpoint.

It is not a fine-tune and it is not claimed to beat the frontier labs. The honest pitch:

- **Frontier-size, fully private.** A 480B coder running on hardware you (RMDW) own, no tokens leaving the building.
- **Flat-rate, not metered.** One monthly price, send the requests your work needs.
- **Capability over speed.** Because it is a frontier-size model on a home cluster, it trades throughput for size: expect roughly **13 tokens/second**, slower than the entry Kaiju-Coder. You run Super Kaiju when you want the larger model, not when you want the fastest one.

## Model details

- **Base model:** [Qwen/Qwen3-Coder-480B-A35B-Instruct](https://huggingface.co/Qwen/Qwen3-Coder-480B-A35B-Instruct) (Apache-2.0)
- **Served quant:** [mlx-community/Qwen3-Coder-480B-A35B-Instruct-4bit](https://huggingface.co/mlx-community/Qwen3-Coder-480B-A35B-Instruct-4bit) (~270 GB)
- **Serving:** MLX pipeline-parallel across 2× Apple M3 Ultra (256 GB each), JACCL/RDMA over Thunderbolt, custom main-thread inference server
- **Context:** 256K (extendable)
- **Interface:** OpenAI-compatible `POST /v1/chat/completions`, streaming and non-streaming
- **License:** Apache-2.0, fine-tuned-from / served-from Qwen under Apache 2.0. No Qwen or Alibaba endorsement implied.

## Intended use

Building complete websites and apps, wiring Stripe and auth, writing scripts and automations, drafting proposals and invoices, and the rest of the real work that ships a one-person business, on a private endpoint with no per-token meter.

## How to use

```bash
curl https://api.rmdw.ai/v1/chat/completions \
  -H "Authorization: Bearer rmdw-YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"super-kaiju","messages":[{"role":"user","content":"Write a Python function that returns the nth Fibonacci number."}]}'
```
