๐ OBSIDIAN-9B-Coder
Complete Code ยท Long Context ยท Interactive Software
OBSIDIAN-9B-Coder is a 9B-class coding model fine-tuned from Jackrong/Qwopus3.5-9B-Coder using the Coder Max Multilingual dataset.
The model is specialized in generating complete software implementations, with a strong focus on modern frontend development, interactive browser applications, Three.js, HTML5 Canvas, JavaScript, HTML/CSS, Python and general programming.
OBSIDIAN is designed around a simple objective:
Generate the implementation, not fragments of it.

OBSIDIAN
OBSIDIAN is fine-tuned to preserve long application structures including:
- document layout;
- styles;
- application state;
- event handlers;
- rendering logic;
- animation loops;
- user interaction;
- game logic;
- DOM lifecycle;
- complete closing structures.
๐ฎ Three.js Specialization
Three.js is one of the primary specialization targets of OBSIDIAN.
Training examples contain patterns involving:
- Scene creation
- Perspective cameras
- Lighting
- Meshes
- Materials
- Geometry
- Animation loops
- Keyboard input
- Mouse interaction
- Game mechanics
- Collision logic
- 3D environments
- Interactive simulations
- Complete browser games
- Single-file Three.js applications
The objective is not simply to teach isolated Three.js API calls.
The model is trained to connect the different components required to produce an actual working application.
For example:
Scene
โ
โโโ Camera
โโโ Renderer
โโโ Lighting
โโโ Objects
โ
โโโ Materials
โ
โโโ Input
โโโ State
โโโ Game Logic
โโโ Animation Loop
๐ Frontend Generation
OBSIDIAN has strong exposure to complete frontend applications combining:
HTML
โ
โโโ CSS
โ
โโโ JavaScript
โ
โโโ DOM
โโโ State
โโโ Events
โโโ Canvas
โโโ Three.js
โโโ Rendering
โโโ Animation
A typical training target may contain an entire application:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style>
/* Complete interface */
</style>
</head>
<body>
<main>
<!-- Complete application -->
</main>
<script>
// Application state
// Event handling
// Rendering
// Interaction
// Animation loop
</script>
</body>
</html>
The objective is to reduce common failure modes where coding models generate the beginning of an application but fail to correctly complete its architecture.
๐ Multilingual Programming
OBSIDIAN was fine-tuned with programming instructions across 10 languages.
| Language | Code |
|---|---|
| Portuguรชs | pt |
| English | en |
| Espaรฑol | es |
| Franรงais | fr |
| Deutsch | de |
| Italiano | it |
| ๆฅๆฌ่ช | ja |
| ็ฎไฝไธญๆ | zh |
| ะ ัััะบะธะน | ru |
| Tรผrkรงe | tr |
The goal is to make coding capability less dependent on the natural language used in the instruction.
A developer can therefore ask for implementations using prompts in multiple languages while still requesting code in the same programming ecosystem.
๐๏ธ Training Dataset
OBSIDIAN-9B-Coder was fine-tuned using Coder Max Multilingual.
Dataset:
guell00/Coder-max
Coder Max is a conversational supervised fine-tuning dataset focused heavily on code generation.
The corpus was designed around complete implementations rather than heavily truncated programming responses.

๐ Coder Max Scale
Coder Max is distributed in multiple incremental variants.

The larger variants contain the content represented by the smaller variants, allowing different training scales without requiring manual concatenation.
๐งน Dataset Curation
Coder Max was built with a code-oriented preprocessing pipeline.
Important characteristics include:
Code Density
More than 95% of the larger corpus variants consist of code-oriented content.
Python Syntax Validation
Python blocks were structurally checked during preprocessing.
Invalid or corrupted samples could therefore be removed before training.
Complete Code Preservation
Long HTML, CSS and JavaScript applications are preserved rather than intentionally truncated.
This is especially important for teaching:
- closing tags;
- application state;
- complete functions;
- event listeners;
- rendering loops;
- lifecycle logic.
Data Sanitization
The preprocessing pipeline targets removal of artifacts such as:
- credentials;
- API keys;
- local IP addresses;
- runtime artifacts.
Provenance
Dataset records include SHA-256-based provenance metadata.
๐งช Fine-Tuning
OBSIDIAN-9B-Coder was produced using supervised fine-tuning with LoRA.
Training configuration:
Training method LoRA
Precision BF16
LoRA rank 16
LoRA alpha 32
LoRA dropout 0
Context target 32,768
Trainer Unsloth
Optimizer AdamW BNB 8-bit
Scheduler Cosine
Response-only training Enabled
LoRA target modules:
q_proj
k_proj
v_proj
o_proj
gate_proj
up_proj
down_proj
๐งฌ Training Strategy
The model was trained using a code-heavy SFT corpus designed around long-form completions.
Important characteristics include:
- long HTML responses;
- complete application generation;
- high-value specialization examples;
- multilingual prompt variants;
- frontend-oriented training;
- Three.js exposure;
- Canvas exposure;
- JavaScript-heavy examples;
- assistant-response-only loss.
Some repetitions in the source dataset may be intentional.
Selected programming concepts and application patterns can be repeated to reinforce specific behaviors and specialization targets.

๐๏ธ Generation Settings
Coding tasks generally benefit from conservative sampling.
A reasonable starting point:
temperature: 0.2
top_p: 0.9
For more creative frontend generation:
temperature: 0.5 - 0.7
top_p: 0.9 - 0.95
These values are starting points rather than guaranteed optimal settings.
Generation parameters should be benchmarked for the target workload.
๐ฏ Intended Use
OBSIDIAN-9B-Coder is intended for:
- Coding assistants
- Frontend code generation
- HTML/CSS/JavaScript generation
- Three.js applications
- Browser games
- Canvas applications
- Interactive interfaces
- Python programming
- Programming experiments
- Multilingual coding assistants
- Local coding models

- Rendering-loop correctness
- DOM interaction
- Canvas rendering
- Python syntax
- Algorithmic correctness

For code-generation models, executable correctness is generally more informative than text similarity alone.
โ ๏ธ Limitations
OBSIDIAN-9B-Coder is a generative model.
Generated code can contain:
- logical errors;
- security vulnerabilities;
- hallucinated APIs;
- outdated library usage;
- incomplete edge-case handling;
- incorrect assumptions;
- dependency incompatibilities.
Generated applications should be inspected and tested before production deployment.
Long context capacity also does not guarantee perfect reasoning or perfect retention across every token of a long prompt.
