SottoASR Transcript Cleanup — LFM2.5-350M MLX 5-bit (soup_30)

sottoasr.app · Full precision (bf16) · MLX 4-bit (smaller)

Overview

MLX 5-bit affine quantization of juanquivilla/sotto-cleanup-lfm25-350m. Recommended for Apple Silicon — best size/quality trade-off.

What's new in soup_30

soup_30 extends v45 with targeted training data for five failure modes (multi-number sentences, year-context drift, disconnected number lists, within-input duplicates, long-form preservation), each generated programmatically and audited with a Qwen3.6-27B judge.

Metric v45 soup_30
Number accuracy 95.9% 96.5%
Adversarial benchmark (greedy) 76% 86%

See the bf16 model card for the full pipeline and benchmark numbers.

Usage

from mlx_lm import load, generate
from mlx_lm.sample_utils import make_sampler

model, tokenizer = load("juanquivilla/sotto-cleanup-lfm25-350m-mlx-5bit")
sampler = make_sampler(temp=0.0)

text = "talk about server three sixty"
prompt = f"### Input:\n{text}\n\n### Output:\n"
output = generate(model, tokenizer, prompt=prompt, max_tokens=512, sampler=sampler)
if "###" in output:
    output = output[:output.index("###")].strip()
print(output)
