Veo 3.1 (video)

bash

gen-ai generate -m veo-3.1 -p "a drone shot over a snowy ridge at golden hour" \
  --ar 16:9 -r 1080p -d 8 --audio-gen

json

{ "name": "picsart_generate",
  "arguments": { "model": "veo-3.1", "prompt": "a drone shot over a snowy ridge", "duration": 8, "resolution": "1080p", "generateAudio": true } }

Veo clips are chainable with gen-ai extend (+7s per segment). Full params for every Veo / Gemini / Imagen / Lyria model are in Parameters below.

Nano Banana Pro (image)

bash

gen-ai generate -m gemini-3-pro-image -p "a cinematic product render of a smart speaker" --ar 16:9 -r 4K

Gemini TTS & Lyria (audio)

bash

gen-ai generate -m gemini-2.5-pro-tts -p "Here is your daily briefing."   # speech
gen-ai generate -m lyria-3-pro -p "uplifting cinematic orchestral score"  # music

Parameters

Full parameter surface for every model, sourced from gen-ai models info <id> --json. CLI flags show the primary short form; the canonical --kebab-case long form always works too.
