YouTube Summariser Qwen3.5 4B

This is a Tuned Tensor fine-tune of Qwen/Qwen3.5-4B for generating concise Markdown summaries of YouTube transcripts.

It is intended for local/offline use with the youtube-summariser CLI and similar transcript summarization workflows.

Usage

Install recent local model dependencies first. This checkpoint was exported with Transformers 5.6.2 metadata.

pip install 'transformers>=5.6.2' torch accelerate safetensors huggingface_hub

Download locally for the CLI:

huggingface-cli download weijianzhg/youtube-summariser-qwen3.5-4b \
  --local-dir ./youtube-summariser-qwen3.5-4b

youtube-summariser 'https://youtu.be/VIDEO_ID' \
  --local-model ./youtube-summariser-qwen3.5-4b

For long videos, use the CLI's automatic long-video mode so full transcripts are chunked and synthesized instead of truncated:

youtube-summariser 'https://youtu.be/VIDEO_ID' \
  --local-model ./youtube-summariser-qwen3.5-4b \
  --summary-strategy auto

Limitations

This is a small task-specific fine-tune trained on a small dataset. It is useful for testing local YouTube summarization behavior, but long videos should be summarized with a chunked/map-reduce workflow rather than a single prompt. Generated summaries may omit details or make mistakes; check important claims against the original transcript.
