Generating Media

Generating media

Every model belongs to a mode (image / video / audio) and an input type that describes what goes in and what comes out. Understanding the input type tells you which inputs a model needs.

Input types

The two-letter codes you'll see across the catalog and in picsart_model_info:

Code	Meaning	Typical inputs
t2i	text → image	prompt
i2i	image → image	prompt + image
t2v	text → video	prompt
i2v	image → video	prompt + image
v2v	video → video	prompt + video
a2v	audio → video	prompt + audio
tts	text → speech	text + voice
sts	speech → speech	audio
sfx	sound effects	prompt
music	music	prompt

Providing inputs

CLI — pass files as local paths or URLs. Local files are uploaded for you before the request is submitted:

# image-to-video: animate a still
gen-ai generate -m wan-2.7-i2v -p "gentle parallax, drifting clouds" -i ./hero.png

# video-to-video: restyle a clip
gen-ai generate -m seedance-2.0-video-edit -p "claymation style" --video ./clip.mp4

MCP — pass imageUrls / videoUrl (must be reachable URLs):

{ "name": "picsart_generate",
  "arguments": { "model": "wan-2.7-i2v", "prompt": "gentle parallax", "imageUrls": ["https://example.com/hero.png"] } }

Model-specific parameters

Beyond the common params (aspectRatio, resolution, duration, count…), each model has its own surface — for example, Veo 3.1 accepts startFrame/endFrame keyframes and generateAudio, while ElevenLabs models accept voiceId and language.

Discover the exact surface:

gen-ai models info veo-3.1 --json          # full paramConfig
gen-ai generate -m veo-3.1 -p "x" --dry-run  # preview the resolved payload

{ "name": "picsart_model_params", "arguments": { "model": "veo-3.1" } }

In the CLI, model-specific params are flags (--start-frame, --voice, …). Via MCP, pass them in the extra object.

Outputs

A generation returns one or more result URLs. Control delivery:

• CLI: downloaded to ./output by default; use --no-download (URL only), --download <dir>, or --save-to-drive.
• MCP: results: [{ url }] plus a resource_link per output. Optionally written to Drive when enabled.

Some models return multiple results from one call (e.g. an Explore model returning several images) — the result items array simply has more than one entry.

Validate before you spend

echo '{"prompt":"test","duration":99}' | gen-ai validate -m seedance-2.0

{ "name": "picsart_validate_params", "arguments": { "model": "seedance-2.0", "params": { "duration": 99 } } }
