Summarization

Generate concise summaries from long text using abstractive summarization models.

For full API reference (summarize(), summarizeMany(), options, result types, and custom providers), see the Core Summarization guide.

Recommended Models

Model	Size	Speed	Use Case
`Xenova/distilbart-cnn-6-6`	~300MB	⚡⚡	General-purpose summarization
`Xenova/distilbart-cnn-12-6`	~400MB	⚡	Higher quality summaries

Configurable Length

Based on the Text Summarizer showcase app:

import { transformers } from '@localmode/transformers';
import { summarize } from '@localmode/core';

const model = transformers.summarizer('Xenova/distilbart-cnn-6-6');

// Short summary
const { summary: brief } = await summarize({
  model,
  text: longDocument,
  maxLength: 60,
  minLength: 20,
});

// Medium summary
const { summary: medium } = await summarize({
  model,
  text: longDocument,
  maxLength: 150,
  minLength: 60,
});

// Detailed summary
const { summary: detailed } = await summarize({
  model,
  text: longDocument,
  maxLength: 300,
  minLength: 100,
});

Meeting Notes Example

Based on the Meeting Assistant showcase app — combine speech-to-text with summarization:

import { transcribe, summarize } from '@localmode/core';

// First transcribe the meeting audio
const { text: transcript } = await transcribe({
  model: speechModel,
  audio: meetingAudio,
});

// Then summarize the transcript
const { summary } = await summarize({
  model: summarizerModel,
  text: transcript,
  maxLength: 200,
  minLength: 60,
});

Best Practices

Summarization Tips

Set length constraints — Use maxLength and minLength to control summary size
Input length matters — Models have a max input length; very long texts may need chunking
Abstractive output — Summaries are generated text, not extracted sentences
Use AbortSignal — Summarization can take several seconds; support cancellation
