The composer: models, resolution, concepts

The composer is the message box at the bottom of chat — but it is also where you control how images get made: which model, what aspect ratio, what resolution, how many concepts. The input grows as you write longer briefs and caps at a comfortable height.

The models

• Nano Banana — the default, and the fast, economical pick for drafts and exploring directions. 2 credits per image, fixed at 1K.
• Nano Banana 2 — the step up for client-ready work, and what we use for ~99% of finished shots. From 4 credits per image, up to 2K/4K.
• Nano Banana Pro — the realism-focused option when skin, fabric, and light need to survive close inspection. 8 credits per image at 1K/2K, 16 at 4K.

Why offer more than one? It is a quality-and-cost ladder. Start on Nano Banana to explore cheaply, step up to Nano Banana 2 for the shots you will actually ship, and reach for Pro when fine detail has to survive close inspection. Spend credits where they earn it.

Resolution: 1K, 2K, 4K

For client work, generate at 2K minimum — 1K turns blurry as soon as anyone zooms. Resolution is not just output size: higher resolution measurably improves the model’s output quality. Go 4K when your input image is at least 2K on a side, when the product has fine detail, or when there is text on the product that must render correctly. The practical rule: start at 2K; if the result is not crisp enough, go to 4K.

Concepts and variations

• Concepts = different creative interpretations of one brief. Ask for "a woman wearing the t-shirt" with 3 concepts and you might get golden hour, editorial, and lifestyle-UGC takes — three directions for the price of one brief.
• Variations = the same prompt run again. Each run differs slightly in the fine details, which is exactly what you want for accuracy-critical products like jewelry: generate variations and keep the one where the details land.

Loop and Vision

• Loop (experimental) — Awa keeps generating, self-evaluating, and retrying until the result meets the brief. Use it when you know exactly what you want on a hard subject (fine jewelry, precise detail) and would rather spend credits than rounds of manual feedback. It multiplies cost and time per image — that is the tradeoff, and why it is off by default.
• Vision (off by default) — lets Awa actually look at the frames it generated and critique them. Adds time per generation; worth switching on for complex products, unnecessary for routine shots.

Aspect ratio

Set aspect ratio to match the destination before generating — square for PDP grids, portrait for stories, landscape for banners — rather than cropping afterwards.
