npm install -g @earendil-works/pi-coding-agent
# Add to ~/.pi/agent/models.json:
{
  "providers": {
    "mlx-lm": {
      "baseUrl": "http://localhost:8080/v1",
      "api": "openai-completions",
      "apiKey": "none",
      "models": [
        {
          "id": "ipetrukha/LFM2.5-350M-MLX-8bit"
        }
      ]
    }
  }
}

LFM2.5-350M-MLX-8bit

Re-quantization of LiquidAI/LFM2.5-350M (revision 9e6c6ccf47cd318696e137d381a7ded8fe4df09f) with mlx-lm 0.31.3: affine, 8 bit, group size 64, no per-layer overrides — the same recipe as LiquidAI/LFM2.5-350M-MLX-8bit.

The one difference: this checkpoint stores quantization scales and biases in bfloat16, while the official MLX quant stores them in float32. Published so cross-engine benchmarks compare engines under one activation dtype.

Reproduce:

mlx_lm.convert --hf-path LiquidAI/LFM2.5-350M -q --q-bits 8 --q-group-size 64
