How to use majentik/BigBang-v1-MLX-2bit with Pi:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "majentik/BigBang-v1-MLX-2bit"

Configure the model in 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": "majentik/BigBang-v1-MLX-2bit"
        }
      ]
    }
  }
}

BigBang-v1-MLX-2bit

MLX 2bit (affine, group size 32) quantized variant of endless-frontier/BigBang-v1 (text tower quantized; vision tower and projector retained in BF16) for Apple silicon via mlx-lm.

Provenance

Source: endless-frontier/BigBang-v1 @ revision fe313c9057ca2c51a07c7cf141915dc8cc3f620e (Apache-2.0 (upstream LICENSE)).
Quantized with mlx_lm.convert (mlx-lm 0.31.3): affine, 2-bit, group size 32.

Smoke gate

Before upload this pack passed a deterministic coherence gate: greedy 48-token chat generation loaded through mlx_lm.load, judged for emptiness, repetition loops, multi-script gibberish, and special-token debris. Verdict: ok.

Usage

pip install mlx-lm
mlx_lm.generate --model majentik/BigBang-v1-MLX-2bit --prompt "Hello"
