Instructions to use vietrix/viena-60m with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use vietrix/viena-60m with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="vietrix/viena-60m")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("vietrix/viena-60m")
model = AutoModelForMultimodalLM.from_pretrained("vietrix/viena-60m")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

vLLM

How to use vietrix/viena-60m with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "vietrix/viena-60m"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "vietrix/viena-60m",
		"messages": [
			{
				"role": "user",
				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/vietrix/viena-60m

SGLang

How to use vietrix/viena-60m with SGLang:

Install from pip and serve model

# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "vietrix/viena-60m" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/chat/completions" \

+# Viena 60M (SFT)
+## Model details
+- Developed by: Vietrix
+- Model type: decoder-only causal LM (Llama-style)
+- Parameters: ~60M
+- Layers: 16
+- Hidden size: 512
+- Attention heads: 8 (KV heads: 4)
+- Max sequence length: 1024
+- RoPE theta: 10000
+- Normalization/MLP: RMSNorm + SwiGLU
+- Precision: BF16 training
+## Tokenizer
+- SentencePiece BPE
+- Target vocab in config: 32k
+- Actual vocab in tokenizer.model: 2105 (trained on a small corpus)
+- Note: embeddings are sized for 32k; only the first 2105 tokens are used by the tokenizer.
+## Training data
+- Internal synthetic Vietnamese instruction/chat data.
+- Train/val split: 2,000 / 200 JSONL records.
+- Format: messages with roles (system/user/assistant/tool).
+- PII: best-effort redaction applied during dataset preparation.
+## Fine-tuning procedure
+- Initialized from: `vietrix/viena-60m-pretrain`.
+- Objective: token-level cross-entropy, prompt loss disabled.
+- Sequence length: 1024.
+- Global batch size: 32 (batch 8 x grad_accum 4).
+- Optimizer: AdamW, lr 2e-4, weight decay 0.01, cosine decay with warmup.
+- Steps: 1,000.
+- Validation every 200 steps (10 batches).
+## Intended use
+- Vietnamese chat/instruction-following use cases.
+- Research and prototyping; not a production-grade safety model.
+## Limitations
+- Trained on a small synthetic corpus; may hallucinate or respond incorrectly.
+- Not safety-tuned for sensitive domains.
+- Tokenizer vocab is small; lexical coverage is limited.
+## How to use
+```python
+from transformers import AutoModelForCausalLM, AutoTokenizer
+model_id = "vietrix/viena-60m"
+tokenizer = AutoTokenizer.from_pretrained(model_id, use_fast=False)
+model = AutoModelForCausalLM.from_pretrained(model_id)
+```
+If `AutoTokenizer` fails, load the SentencePiece model explicitly:
+```python
+from transformers import LlamaTokenizer
+tokenizer = LlamaTokenizer.from_pretrained(model_id, use_fast=False)
+```
