FAQ

What models can I use?

Gemini 2.5 (text), Banana / Nano Banana Pro (image), and Sora 2, Veo 3.1 Fast, Hailuo 2.3, Kling 2.6, Seedance 1.0 Pro Fast (video).

Banana vs Nano Banana Pro?

• Banana: fast, up to 3 reference images, great for quick iterations.
• Nano Banana Pro: premium quality, up to 8 references, resolutions 1K/2K/4K.

How do Sora references work?

Use an image for First‑Frame or a video for Remix. The backend automatically makes local images accessible via a public URL when required.

What is a PID?

For Sora, the Result node shows a Process ID (PID). Use it for remix/debugging and status checks.

Why can’t I connect some nodes?

Handles enforce types: 🟡 Text, 🟢 Image, 🔵 Video. Incompatible ports are blocked.

Can I chain results into a new generation?

Yes. Connect a Result node output to a Prompt node to iterate, change models, or combine modalities.

Veo tips

• First/Last frames: connect 1–2 images to control the animation endpoints.
• Reference mode (REFERENCE_2_VIDEO): requires veo3_fast, 1–3 images, and 16:9.
• 1080p output is available only with 16:9 and may take longer; fallback behavior can yield 720p first.

How are workflows saved?

Your graph is auto‑saved to the cloud. Create snapshots, share public links, and remix.

Where do I manage credits?

Open the Pricing page to view remaining credits and upgrade.

Are my API keys safe?

Yes. The frontend stores no keys. A secure Backend‑for‑Frontend proxy handles all provider calls.
