# Ycoder-medium

`Ycoder-medium` is an experimental local fine-tune of `Qwen/Qwen2.5-Coder-0.5B-Instruct` created by **louhless**.

It is targeted at:

- OpenGL / GLSL
- Python
- German replies
- cautious 2025-2026 news and public-health summaries

## Important Note

This model is **not trained from scratch**.

It is a small LoRA fine-tune on top of `Qwen/Qwen2.5-Coder-0.5B-Instruct`.

The goal is to improve behavior in a narrow target set. Any “15% improvement” claim should be treated as a target, not a verified benchmark result, unless evaluated on a fixed benchmark before and after training.

## Model Details

- **Model name:** `Ycoder-medium`
- **Creator:** `louhless`
- **Base model:** `Qwen/Qwen2.5-Coder-0.5B-Instruct`
- **Architecture:** Qwen2 causal language model
- **Context length:** 32768
- **Language:** English and German
- **Export:** GGUF available
- **Status:** experimental

## Training Focus

The model was tuned for:

- Python utility code
- Python code explanations
- GLSL fragment shaders
- GLSL vertex shaders
- OpenGL concepts such as VAO/VBO
- German short-form answers
- simple math
- cautious dated summaries for 2025-2026 public-health/news topics

## News / Health Safety

For topics such as Hantavirus, the project uses both small fine-tuning examples and local dated context snippets.

This is intentional: recent news and public-health information should not be trusted from model weights alone.

The model should:

- answer cautiously
- mention dates when relevant
- avoid medical diagnosis
- avoid treatment promises
- recommend official sources such as WHO, CDC, ECDC, or local health authorities

It should **not** be used for diagnosis or medical decision-making.

## Training Data

The initial custom dataset includes examples for:

- Python utility functions and explanations
- GLSL shaders and OpenGL concepts
- German short answers
- simple math
- dated 2025-2026 Hantavirus summaries based on WHO, CDC, and ECDC public information
