		"model": "xunker/CodeLens-7B-MLX",
		"prompt": "Once upon a time,",
		"max_tokens": 512,
		"temperature": 0.5
	}'

Use Docker images

docker run --gpus all \
    --shm-size 32g \
    -p 30000:30000 \

+# [CodeLens-7B-MLX](https://huggingface.co/xunker/CodeLens-7B-MLX)
+MLX version of [sriksven/CodeLens-7B](https://huggingface.co/sriksven/CodeLens-7B) in various oQ levels and dtypes.

+## Why choose FP16 over BFLOAT16/BF16?
+On older Apple Silicon (M1 and M2), fp16 can be faster. Here are the details from [Muhammad Raza](https://muhammadraza.me/2026/gguf-vs-mlx-decision-guide/#two-traps-that-will-flip-your-results):
+> A lot of MLX builds ship as bf16, and **on the M1 and M2 that data type does not get the accelerated path that fp16 does**. During prefill those weights run un-accelerated and the penalty multiplies across every input token, which is part of why some “MLX is slow” reports come from older hardware. [...]
+>
+> If you are on an M1 or M2 and MLX feels sluggish, check this before you blame the format.
+## Hardware and Software
+These were converted to MLX using [oMLX](https://github.com/jundot/omlx) [0.4.4](https://github.com/jundot/omlx/releases/tag/v0.4.4) on a 32GB Macbook Pro 2021 (M1 Pro). I cleared all my RAM so you don't have to.
