Sweep Next-Edit 1.5B (MLX)

A 1.5B parameter model for next-edit autocomplete, quantized to 8bit MLX format.

Model Description

Sweep Next-Edit predicts your next code edit before you make it. It runs locally on your laptop in under 500ms (with speculative decoding) and outperforms models over 4x its size on next-edit benchmarks. More details here.

Usage

pip install mlx-lm

from mlx_lm import load, generate

model, tokenizer = load("Farok/sweep-next-edit-1.5b-mlx")

prompt = "hello"

if tokenizer.chat_template is not None:
    messages = [{"role": "user", "content": prompt}]
    prompt = tokenizer.apply_chat_template(
        messages, add_generation_prompt=True, return_dict=False,
    )

response = generate(model, tokenizer, prompt=prompt, verbose=True)

Model Details

• Format: MLX (8bit)
• Parameters: 1.5B
• Context Length: 8192 tokens
• Base Model: Qwen2.5-Coder

Example

The model uses a specific prompt format with file context, recent diffs, and current state to predict the next edit. See run_model.py for a complete example.
