Same brief, side by side

Both models got the same two briefs, once each. Both at 1K, Lite's only size.

Test 1: product photo with on-image text

Brief: a ceramic coffee mug printed with "Route 42 Coffee Co.", on a wood table, shot as a commercial flat-lay.

Nano Banana 2 Lite:

What's visibly different: both render the two-line label cleanly. Nano Banana 2 keeps slightly sharper wood grain and a tighter depth of field; Lite is softer in the background. For a thumbnail or a listing image, either works.

Test 2: fine detail and texture

Brief: a close-up portrait of a watchmaker with small gears, a loupe, skin texture and warm directional light.

What's visibly different: this is where the gap shows. Nano Banana 2 resolves the gear teeth and the loupe reflection; Lite goes soft in the same region. For anything a viewer will zoom into, macro product shots, technical illustration, small text, that's what the extra $0.003 at 1K buys, and 2K or 4K widens it further.

Which to choose

• Volume at 1K: Lite, $0.033 flat. Social thumbnails, drafts, A/B variants.
• 2K or 4K output: Nano Banana 2. Lite stops at 1K.
• Fine detail people will zoom into: Nano Banana 2.
• PNG or JPG choice: Nano Banana 2. Lite has no output_format.
• Until November 8: Nano Banana 2 at 1K is $0.018 on sale, below Lite's $0.033. After the sale, Lite is the cheaper 1K again.
• Mixed pipeline: draft on Lite, re-render the winner on Nano Banana 2 at the size you ship.

Switching between them

Both run on POST /v1/tasks, but the schemas differ. Lite rejects resolution and output_format with HTTP 400, and its references go in image_urls instead of image_input.
