Nano Banana 2 vs GPT Image 2 for AI Personas

Nano Banana 2 and GPT Image 2 are both excellent, and both will frustrate you if you use them for the wrong job. The choice is not "which is better" overall, it is "which fits this shot." For AI influencer and UGC work, the tradeoff comes down to realism, resolution, and how much prompt effort you want to invest.

GPT Image 2: peak realism, with effort

GPT Image 2 is the stronger candidate for realism. It can produce images that read as genuinely photographed rather than rendered, but it earns that result only with descriptive, deliberate prompting: specific framing, light, lens feel, and texture. It also generates at lower resolutions, so it is best when realism is the priority and you plan to upscale afterward if you need size.

• Best for: maximum realism, candid-feeling shots, prompters willing to write detailed scene language.
• Watch for: lower native resolution; vague prompts give mediocre results.

Nano Banana 2: high resolution and reference edits

Nano Banana 2 supports resolutions up to 4K and is excellent at identity-locked edits from a reference, which makes it the workhorse for same-face sets at large sizes. The tradeoff is finish: its output tends to have a more polished, slightly more "AI" look than GPT Image 2. For many lifestyle feeds that polish is fine, and the resolution plus reference fidelity are worth it.

• Best for: resolutions up to 4K, identity-locked edits from a reference, fast same-face sets.
• Watch for: a more polished, less raw look than GPT Image 2.

A simple routing rule

If the shot needs to feel as real as possible and you will craft the prompt, start with GPT Image 2. If you need high resolution or a same-face edit from a reference, start with Nano Banana 2.
