Libraries

How to use inferencerlabs/MiMo-V2.5-LM-MLX-9bit 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("inferencerlabs/MiMo-V2.5-LM-MLX-9bit")

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)

Pi new

How to use inferencerlabs/MiMo-V2.5-LM-MLX-9bit 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/MiMo-V2.5-LM-MLX-9bit"

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/MiMo-V2.5-LM-MLX-9bit"
        }
      ]
    }
  }
}

     "messages": [
       {"role": "user", "content": "Hello"}
     ]
   }'

See MiMo-V2.5 MLX in action - demonstration videos

Tested on a M3 Ultra 512GB RAM using Inferencer app v1.11.1

Text inference: ~28 tokens/s @ 2000 tokens (debug build)
Omnimodal inference: Not included in this language model (LM) only version
Memory usage: ~323 GiB

Q9 typically achieves near lossless accuracy in our coding test

Quantization (bpw)	Perplexity	Token Accuracy	Missed Divergence
Q3.5	197.0	44.05%	72.00%
Q4.5	1.35937	89.75%	28.98%
Q5.5	1.24218	94.60%	17.55%
Q6.5	1.21875	96.85%	16.03%
Q8.5	1.21875	97.65%	9.92%
Q9	1.21093	97.80%	9.60%
Base	1.20312	100.0%	0.000%

Perplexity: Measures the confidence for predicting base tokens (lower is better)
Token Accuracy: The percentage of correctly generated base tokens
Missed Divergence: Measures severity of misses; how much the token was missed by

Quantized with a modified version of MLX
