Where Seedream 4.5 stands out

Light and atmosphere: sunsets, window light and night scenes come out the most dramatic of the three models we run.
2K output, which also works as a 1.5–2× upscale for phone photos.
Product and ad scenes from one sentence.

The trade-off: Seedream re-frames more freely. In our tests it re-composed the living room and cropped the dog tighter. If your framing must stay exactly the same, use Nano Banana 2.

Frequently asked questions

Is this Seedream 4.5 or 4.0?

Seedream 4.5 (bytedance-seed/seedream-4.5 via OpenRouter). If it is down, the edit falls back to Nano Banana 2 instead of failing.

What resolution do I get?

Up to 2K on the long side, keeping your photo’s aspect ratio.

Which model should I pick?

Small edits (clothes, objects, light, colour): start with the free standard edit (Nano Banana 2 Lite). Big scene changes: Nano Banana 2 keeps your framing best. For the most dramatic light and 2K output: Seedream 4.5. In our five tests the Lite model missed two big scene changes; both 2-credit models got all five.

What does it cost?

One free standard edit per day without an account. After that, credits: a standard edit is 1 credit and Nano Banana 2 or Seedream 4.5 is 2 credits. Packs start at $9.90 for 120 credits, so a 2-credit edit is about 14–17¢. Failed edits are refunded automatically.

Is it really free without sign-up?

Yes. Every visitor gets one free standard edit per day with no account, email or card. More edits use credits: packs start at $9.90 for 120 credits (about 8¢ an edit), and a standard edit costs 1 credit.

Do you keep my photos?

No. Your photo is sent to the AI model only to make the edit, then discarded. We never store the photo or the result on our servers, and we never use them for training. The edited photo is returned straight to your browser.
