Performance Benchmarks

Measured Benchmarks (Apple M1)

Metric	4-bit	8-bit	16-bit
Tokens/sec	84.99	52.29	32.34
TTFT	11.77 ms	19.14 ms	30.93 ms

Benchmarked on Apple M1 with 8GB unified memory. Average over 5 runs with 256 max tokens.

Multi-Quantization Comparison

Evaluate your hardware budget and choose the optimal precision:

Variant	Disk Size	VRAM Footprint	Target Apple Silicon Hardware	Key Advantage
4-bit MLX (This Repository)	~450 MB	~490 MB	M1 / M2 / M3 / M4 (8GB+ Unified Memory)	Ultra-compact footprint, maximum generation speed; negligible memory pressure.
8-bit MLX	~855 MB	~900 MB	M1 / M2 / M3 / M4 (8GB+ Unified Memory)	Near-lossless precision with an extremely lightweight footprint.
16-bit MLX	~1620 MB	~1690 MB	M1 / M2 / M3 / M4 (8GB+ Unified Memory)	Full unquantized precision; zero perplexity penalty for reference evaluation.

Who Should Use This?

Your Hardware	Recommended Quantization
M1/M2/M3/M4 (8GB – 16GB)	4-bit — Best balance of speed, low memory, and multitasking capability
M1/M2/M3/M4 Pro/Max (18GB – 36GB)	8-bit — Higher quality reasoning with comfortable memory headroom
M1/M2/M3/M4 Max/Ultra (36GB – 192GB)	16-bit — Unquantized full precision, zero quality degradation

General guidance:

Use 4-bit if you want to run this model alongside IDEs, browsers, and background development tools.
Use 8-bit if you have 16GB+ unified memory and require superior reasoning and code accuracy.
Use 16-bit for research, benchmarking, evaluation, or high-end workstation deployments.

LM Studio & Local Inference Setup Guide

To prevent runaway loops and ensure correct conversational turn-taking, configure custom stop tokens in your local inference runtime:

<|im_start|>
<|im_end|>
<|endoftext|>

Prompt Template Formatting

System Prefix: <|im_start|>system\n
System Suffix: <|im_end|>\n
User Prefix: <|im_start|>user\n
Assistant Suffix: <|im_end|>\n<|im_start|>assistant\n

Reproduction

To reproduce this conversion:

pip install mlx-lm==0.31.3
python3 -m mlx_lm.convert --hf-path togethercomputer/Tev1-0.8B-experimental --mlx-path output/Tev1-0.8B-experimental-mlx-4bit -q --q-bits 4

Limitations & Known Issues

4-bit group-wise quantization introduces minor precision loss compared to unquantized weights; for deep mathematical derivations or precision-critical reasoning, test the 8-bit or 16-bit variants.
High context sequences (>32K tokens) require sufficient unified memory headroom; ensure unified memory is not overcommitted.
This is a weight-only MLX conversion designed specifically for Apple Silicon GPUs (M1/M2/M3/M4 series).
