Pi new

How to use inferencerlabs/IQuest-Coder-V1-40B-Loop-Instruct-MLX-6.5bit with Pi:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "inferencerlabs/IQuest-Coder-V1-40B-Loop-Instruct-MLX-6.5bit"

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": "inferencerlabs/IQuest-Coder-V1-40B-Loop-Instruct-MLX-6.5bit"
        }
      ]
