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, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("vietrix/viena-60m")
model = AutoModelForCausalLM.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]:]))

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

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:

from transformers import LlamaTokenizer

tokenizer = LlamaTokenizer.from_pretrained(model_id, use_fast=False)
