### MLX (Apple Silicon)

4-bit quantized version in `MLX-4bit/` folder - optimized for M1/M2/M3/M4 Macs.

## Quick Start

### Ollama (Easiest)

```bash
ollama run richardyoung/olmo-3-7b-rlzero-math
```

### llama.cpp

```bash
# Download Q4_K_M (recommended)
wget https://huggingface.co/richardyoung/OLMo-3-7B-RLZero-Math-GGUF/resolve/main/Olmo-3-7B-RLZero-Math-Q4_K_M.gguf

# Run inference
./llama-cli -m Olmo-3-7B-RLZero-Math-Q4_K_M.gguf \
  -p "Solve step by step: What is 15% of 240?" \
  -n 512
```

### MLX (Apple Silicon)

```bash
pip install mlx-lm

mlx_lm.generate \
  --model richardyoung/OLMo-3-7B-RLZero-Math-GGUF \
  --prompt "Solve: Find the derivative of x^3 + 2x" \
  --trust-remote-code
```

### Python

```python
from llama_cpp import Llama

llm = Llama(
    model_path="Olmo-3-7B-RLZero-Math-Q4_K_M.gguf",
    n_ctx=4096
)

output = llm(
    "Solve step by step: What is the sum of the first 10 prime numbers?",
    max_tokens=512
)
print(output["choices"][0]["text"])
```

## System Requirements

| Quantization | Min RAM | Recommended | Apple Silicon |
|--------------|---------|-------------|---------------|
| IQ3_M | 4 GB | 8 GB | M1 8GB |
| IQ4_XS / Q4_K_M | 6 GB | 12 GB | M1 8GB |
| Q5_K_M / Q8_0 | 8 GB | 16 GB | M1 16GB |
| F16 | 16 GB | 24 GB | M2 Pro+ |

## Prompt Format

```
Solve the following math problem step by step:
{your problem here}
```

**Example:**
```
Solve the following math problem step by step:
A train travels 120 miles in 2 hours. If it continues at the same speed,
how long will it take to travel 300 miles?
```
