G9v3-3B is a dense 3B causal language model from the AI9Stars team, built for local deployment and resource-constrained scenarios. It targets everyday assistant use, coding, tool-use workflows, and reasoning tasks where a compact model is preferred.

Model Information

Type: Causal Language Model
Architecture: Standard LlamaForCausalLM
Number of Parameters: ~3B
Context Length: 131,072

Quickstart

vLLM

bash

pip install "vllm>=0.21"
vllm serve ai9stars/G9v3-3B --port 8000

bash

curl http://localhost:8000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "ai9stars/G9v3-3B",
    "messages": [{"role": "user", "content": "Who are you?"}],
    "max_tokens": 128,
    "temperature": 0.7
  }'

SGLang

bash

pip install "sglang[srt]>=0.5.12"
python -m sglang.launch_server --model-path ai9stars/G9v3-3B --port 30000

bash

curl http://localhost:30000/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{
    "model": "ai9stars/G9v3-3B",
    "messages": [{"role": "user", "content": "Who are you?"}],
    "max_tokens": 128,
    "temperature": 0.7
  }'

Transformers

pip install -U "transformers>=5.6" accelerate torch

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "ai9stars/G9v3-3B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype="auto",
    device_map="auto",
)

messages = [{"role": "user", "content": "Who are you?"}]
inputs = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    add_generation_prompt=True,
    enable_thinking=False,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=128)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True))

Recommended sampling parameters:

Mode	Recommended params	Enable
Think	`temperature=0.9, top_p=0.95`	`enable_thinking=True`
No Think	`temperature=0.7, top_p=0.95`	`enable_thinking=False`

Limitations and Responsible Use

G9v3-3B is a language model that generates content based on learned statistical patterns from training data. It may produce inaccurate, biased, or unsafe outputs, and generated content should be reviewed and verified before use in high-stakes settings. Users are responsible for evaluating outputs, applying appropriate safeguards, and complying with applicable laws, regulations, and platform policies.
