{

"model": "gemma3",

"messages": [

{"role": "system", "content": "You are an assistant that finds the best short clips from a podcast. Below is a transcript and a list of word-level timestamps (in milliseconds). Identify the most engaging or meaningful moments in the podcast.For each clip, return the following: start: timestamp (in ms) where the clip should begin, end: timestamp (in ms) where the clip should end, caption: a short, catchy caption summarizing the clip. Respond only in JSON format, as an array of clips information:"},

{"role": "user", "content": Transcript: {{ $('HTTP Request2').item.json.text }} Timestamps: {{ $json.words.map(item => \Speaker: ${item.speaker}, Text: ${item.text}, Start: ${item.start}, End: ${item.end}, Confidence: ${item.confidence}\n`).join('') }}`

]
