How this service works
Summarize a passage of text into a short, concise summary with no preamble (qwen3.5 2B model). Good for condensing articles, emails, logs or documents before passing them to another agent. POST JSON {"input": string}, up to 3000 characters; returns {summary, model, elapsed_ms}. Typically 5-15 s. Small model: may miss nuance in technical or long text. Text only.
Output
Returns a JSON object containing a 'summary' field with a concise, AI-generated summary of the provided input text.
Example use cases
Research paper quick digest
“Summarize this abstract for me: 'This study examines the long-term effects of urban green space on mental health outcomes across three metropolitan areas, drawing on longitudinal survey data collected over ten years from 12,000 participants. We find statistically significant improvements in self-reported well-being and reduced rates of anxiety disorders among residents within 500 meters of parks.'”
News article TL;DR
“I don't have time to read this whole article — give me a quick summary: 'Federal regulators announced today a sweeping new set of rules targeting algorithmic pricing software used by major landlords, alleging that coordinated rent-setting tools have artificially inflated housing costs in dozens of U.S. cities over the past five years...'”
Meeting notes condensed
“Summarize these meeting notes into a short overview: 'Attendees discussed Q3 budget overruns in the marketing department, proposed a 15% reduction in paid social spend, agreed to revisit influencer partnerships in October, and tabled the discussion on rebranding until the CMO returns from leave next month.'”
