Libraries

How to use inferencerlabs/GLM-5.2-MLX-Q4.8-INF 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/GLM-5.2-MLX-Q4.8-INF")

prompt = "Write a story about Einstein"
messages = [{"role": "user", "content": prompt}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True
)

GLM 5.2

See GLM 5.2 in action: demonstration videos

Tested with an M3 Ultra 512 GiB using Inferencer app v2.0.4

Text Inference: ~15.8 tokens/s @ 1000 tokens ~417 GiB

Q4.8-INF uses the data-agnostic INF method tuned to yield maximum general accuracy within a 512 GiB memory budget.

Due to system memory and time constraints, the figures shown below are from the conversion of GLM 5.1.

Quantization (bpw)	Perplexity	Token Accuracy	Missed Divergence
Q4.5	1.35937	89.75%	28.98%
Q4.8-INF	1.21093	97.70%	10.65%
Q5.5	1.24218	94.60%	17.55%
Q6.5	1.21875	96.85%	16.03%
Q8.5	1.21875	97.65%	9.92%
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.
