How to use m-i/Step-3.5-Flash-mixed-2-8bit with Pi:
Start the MLX server
# Install MLX LM: uv tool install mlx-lm # Start a local OpenAI-compatible server: mlx_lm.server --model "m-i/Step-3.5-Flash-mixed-2-8bit"
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": "m-i/Step-3.5-Flash-mixed-2-8bit" } ] } } }Run Pi
# Start Pi in your project directory: pi
