# Csermely
|
||
|
||
**The smallest coherent Hungarian language model.** Part of the [Emese](https://emese.tech) model family.
|
||
|
||
Csermely is a 190M parameter decoder-only transformer trained exclusively on high-quality Hungarian text. It runs on edge devices and excels in summarization, grammar checking, and tone detection.
|
||
|
||
## Model Details
|
||
|
||
| | |
|
||
|---|---|
|
||
| **Version** | 0.2 |
|
||
| **Parameters** | 190.2M |
|
||
| **Context length** | 4,096 tokens (YaRN RoPE, 4× factor) |
|
||
| **Architecture** | LLaMA-style (decoder-only transformer) |
|
||
| **Training context** | 1,024 tokens |
|
||
| **Training precision** | bfloat16 (MLX) |
|
||
| **Published weights** | float16 |
|
||
| **Vocabulary** | 32,000 (SentencePiece Unigram, Hungarian) |
|
||
| **Training data** | ~2B tokens of Hungarian text |
|
||
| **License** | MIT |
|
||
|
||
## Architecture
|
||
|
||
- 16 transformer layers
|
||
- 896 hidden dimension
|
||
- 14 attention heads
|
||
- 2560 FFN intermediate size
|
||
- RMSNorm pre-layer normalization
|
||
- Rotary positional embeddings (RoPE) with YaRN extension (4× factor, base 1024)
|
||
- SwiGLU feed-forward activation
|
||
- Tied input/output embeddings
|
||
|
||
## Tokenizer
|
||
|
||
Custom 32K vocabulary SentencePiece Unigram tokenizer trained on high-quality Hungarian corpora. ~30% more token-efficient than multilingual tokenizers for Hungarian text.
|
||
|
||

|
||
|
||
## Usage
|
||
|
||
```python
|
||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
||
tokenizer = AutoTokenizer.from_pretrained("emese-tech/csermely")
|
||
model = AutoModelForCausalLM.from_pretrained("emese-tech/csermely")
|
||
|
||
input_text = "A magyar nyelv"
|
||
inputs = tokenizer(input_text, return_tensors="pt")
|
||
outputs = model.generate(**inputs, max_new_tokens=100)
|
||
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
|
||
```
|
||
|
||
The default generation config uses `temperature=0.7`, `top_p=0.9`, and `repetition_penalty=1.2` to reduce repetitive output.
