Libraries

How to use FahrenheitResearch/FR-Argus-4B with MLX:

# Make sure mlx-lm is installed
# pip install --upgrade mlx-lm

# Generate text with mlx-lm
from mlx_lm import load, generate

model, tokenizer = load("FahrenheitResearch/FR-Argus-4B")

prompt = "Write a story about Einstein"
messages = [{"role": "user", "content": prompt}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True
)

text = generate(model, tokenizer, prompt=prompt, verbose=True)

How to use FahrenheitResearch/FR-Argus-4B with Pi:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "FahrenheitResearch/FR-Argus-4B"

Configure the model in Pi

# Install Pi:
npm install -g @mariozechner/pi-coding-agent
# Add to ~/.pi/agent/models.json:
{
  "providers": {
    "mlx-lm": {
      "baseUrl": "http://localhost:8080/v1",
      "api": "openai-completions",
      "apiKey": "none",
      "models": [
        {
          "id": "FahrenheitResearch/FR-Argus-4B"
        }
      ]
    }
  }
}

Run Pi

# Start Pi in your project directory:

	# FahrenheitResearch/FR-Argus-4B

	This model [FahrenheitResearch/FR-Argus-4B](https://huggingface.co/FahrenheitResearch/FR-Argus-4B) was
	converted to MLX format from [mlx-community/Qwen3-4B-Instruct-2507-4bit](https://huggingface.co/mlx-community/Qwen3-4B-Instruct-2507-4bit)
	using mlx-lm version 0.31.3.

	## Use with mlx

	```bash
	pip install mlx-lm
	```

	```python
	from mlx_lm import load, generate

	model, tokenizer = load("FahrenheitResearch/FR-Argus-4B")

	prompt = "hello"

	if tokenizer.chat_template is not None:
	messages = [{"role": "user", "content": prompt}]
	prompt = tokenizer.apply_chat_template(
	messages, add_generation_prompt=True, return_dict=False,
	)

	response = generate(model, tokenizer, prompt=prompt, verbose=True)
	```
