# 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
