AI QUALITY GATE

70,000× cheaper than a bad render.

Greenlight catches risks in your video early — before it renders. One API call. Any model.

from greenlight import Greenlight

gl = Greenlight(api_key="gl_live_...")

verdict = gl.gate.frame(
    image="storyboard/03.png",
    prompt="wide shot, neon-lit alley, one running figure, rain",
    model="veo-3.1",
)

if verdict.passed:          # score 8.2 / 10  ·  PASS
    render(shot)
else:
    render(verdict.autofix) # prompt rewritten, re-scored, cleared

Model-agnostic — works with Sora · Veo · Kling · Runway · Luma.

Three gates, before a single frame renders.

Idea, prompt, and every frame get checked automatically — before you spend anything on a render.

Frames scoring under your threshold (default 7/10) are re-refined and regenerated automatically — no manual input.

Numbers above are illustrative — wire to live metrics before launch.

The cost of a mistake is a funnel. Gate it before it renders.

Every generation pipeline — image, video, or dubbing — renders first and judges later. A single 10-second video shot costs $1.20 on Runway and up to ~$7 on Sora 2 Pro per attempt, and every failed reroll pays it again. What matters most isn’t catching the mistake — it’s catching it very early. A weak idea, an ambiguous prompt, a broken frame: all visible before you generate, all cheap to fix there. Greenlight gates every idea at the wide top of the funnel — nothing reaches render at the bottom without clearing every check above it.

COST TO CATCH IT BEFORE RENDER

Shift-left QA for creative generation: the cost of a defect rises the later you catch it.

Built as infrastructure, not another dashboard.

Greenlight is an API. Drop one call into your generation pipeline and gate every asset before it renders. No SDK lock-in, no model lock-in.

from greenlight import Greenlight
gl = Greenlight(api_key="gl_live_...")

report = gl.gate.storyboard(
    frames=[{"image": f.url, "prompt": f.prompt} for f in shots],
    model="veo-3.1",
    threshold=7.0,
    audience="gen-z, indonesia, tiktok",
)

for shot in report.frames:
    print(shot.verdict, shot.score, shot.notes)
