Godoter — a Qwen3.6-27B fine-tune for Godot 4 & GDScript
Unofficial hobby project — NOT made by Godot. Godoter is a personal, non-commercial fine-tune made by an independent hobbyist for fun and learning. It is not made, created, maintained, affiliated with, sponsored by, or endorsed by the Godot Foundation or the Godot Engine team. "Godot" is a trademark of the Godot Foundation, used here only to describe what the model is for. Training data includes the official Godot documentation (CC-BY 4.0); the base model is Qwen3.6-27B (Apache 2.0).
Godoter is a 27-billion-parameter model specialized in writing Godot 4 / GDScript. It is a QLoRA fine-tune of Qwen3.6-27B, with the adapter merged back into the base weights so it loads as a normal model.
The point of Godoter is reliability in one domain. A general model knows a bit of Godot, but under pressure it drifts to the wrong engine or mixes up the deprecated Godot 3 API with Godot 4. Godoter stays anchored: it answers in Godot 4 GDScript, every time, and it doesn't confuse versions.
What it's good at
- Writing idiomatic Godot 4 GDScript (nodes, signals, resources,
@export/@onready,await, typed code). - Building complete, multi-file systems: inventory, finite-state-machine AI, save/load, dialogue, multiplayer, shaders, combat (hitbox/hurtbox), navigation, crafting, skill trees, and more.
- Not confusing Godot 3 and Godot 4 APIs (
move_and_slide(),instantiate(),CharacterBody2D/3D,source_color,FileAccess, signal.connect()/.emit(),@rpc, …). - Staying in Godot instead of drifting to Unity, Python, web, or other frameworks.
Benchmark
Godoter vs. the base Qwen3.6-27B, both in the same Q6_K quant, same GPU, same prompts, thinking enabled for both. A task "passes" only if the answer uses the correct Godot 4 API and avoids the deprecated Godot 3 API (the check looks at code blocks, not prose).
| Test | Base Qwen3.6-27B | Godoter |
|---|---|---|
| Easy tasks (Godot 4 migration traps) | 80% | 100% |
| Hard tasks (advanced Godot 4) | 68% | 96% |
On the hard set, reading the actual answers shows why the base struggles:
- Framework drift — asked to "build a skill tree" or a "deck-builder", the base often replies in HTML/CSS/JS or Python; an RPC question gets answered in gRPC/Go; a lobby in WebRTC. It doesn't realize the question is about Godot. Godoter never drifts.
- Lost in reasoning — on some prompts the base spends its whole token budget thinking and never reaches the code.
(The 68% even overstates the base, since the keyword rubric credits wrong-language or incomplete answers. The real gap is larger.)
How it was trained
- Base model:
unsloth/Qwen3.6-27B - Method: QLoRA, rank
r = 16,alpha = 16,adamw_8bit, 4-bit base — adapter then merged to 16-bit. - Dataset (~18,000 examples), all anchored to the official Godot 4 docs:
- exact API reference extraction (methods, properties, signals with signatures)
- documentation-grounded Q&A over the Godot 4 tutorials
- 666 complete, multi-file Godot 4 systems authored as build / explain / extend triples
- real Godot 4 GDScript completion pairs
Usage
This is a qwen3_5 / Qwen3.6 architecture model — it needs transformers 5.x.
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
tok = AutoTokenizer.from_pretrained("Ruler97/Godoter-27B")
model = AutoModelForCausalLM.from_pretrained(
"Ruler97/Godoter-27B", torch_dtype=torch.bfloat16, device_map="auto")
msgs = [{"role": "user", "content": "In Godot 4, make a CharacterBody2D move with the arrow keys."}]
ids = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)
out = model.generate(ids, max_new_tokens=512)
print(tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True))
For local use, prefer the GGUF builds (LM Studio / llama.cpp / Ollama): Ruler97/Godoter-27B-GGUF (Q4 / Q6 / Q8).
Limitations
- It's a derivative of Qwen3.6-27B — ~99% of its capability is the base model; the fine-tune adds Godot-4 reliability, not new general reasoning.
- Knowledge is bounded by the training data and the base's cutoff; very recent Godot 4.x changes may not be reflected.
- The benchmark measures API correctness, not full architectural quality of generated code.
- Like any LLM, it can be confidently wrong — review generated code before shipping.
