About GooseReason-4B

Nemotron-Research-GooseReason-4B-Instruct is NVIDIA's reasoning model built on Qwen3-4B-Instruct-2507 using RLVR. It achieves strong performance on math, code, and STEM reasoning benchmarks while remaining compact at 4B parameters.

Key Capabilities

• Math Reasoning: Strong performance on AIME 2025 and AMC benchmarks
• Code Generation: Competitive on LiveCodeBench and HumanEval
• STEM: Broad science and technical reasoning capabilities
• Thinking Mode: Uses extended thinking (<think> tags) for complex reasoning tasks

Benchmark Highlights

Benchmark	GooseReason-4B
AIME 2025 (avg@64)	55.0
AMC (avg@64)	82.2
LiveCodeBench v6 (pass@1)	30.1
GPQA Diamond (avg@8)	47.5

Usage with MLX

pip install mlx-lm

from mlx_lm import load, generate

model, tokenizer = load("DJLougen/Nemotron-Research-GooseReason-4B-Instruct-MLX-16bit")

messages = [
    {"role": "user", "content": "Solve: What is the sum of all prime numbers less than 20?"}
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
response = generate(model, tokenizer, prompt=prompt, max_tokens=2048)
print(response)

Enabling Extended Thinking

For complex reasoning tasks, the model uses <think> tags automatically. You can also prompt it explicitly:

messages = [
    {
        "role": "system",
        "content": "Think step by step before answering."
    },
    {
        "role": "user",
        "content": "Find all positive integers n such that n^2 + 2n + 2 is divisible by 7."
    }
]
