Nano Banana prompts failing? Why Gemini ignores text

Updated: August 19, 2025

Nano Banana prompts — Introduction

Many users say Nano Banana — Google Gemini’s viral 3D image tool — sometimes ignores text prompts or returns wrong edits. The issue surfaced across social feeds and support forums this week as the Nano-Banana trend exploded. Google’s tool also helped Gemini climb app charts.

Why it matters: creators and brands use prompt wording to get precise edits. When a tool ignores instructions it wastes time and damages trust. This short guide explains common causes and simple fixes.

Why Nano Banana prompts not working — main causes

Users and testers point to three main causes:

Safety filters and content rules. Google’s moderation can block or alter prompts that touch on protected topics. That can make the tool refuse or change edits. Users on Reddit and LiveMint reported results weakened by stricter filters.
Server load and timeouts. The viral spike has pushed Gemini usage up. Sudden high demand can cause timeouts or repeat images. Google support threads show many “same image” and timeout reports.
Prompt ambiguity or missing context. Nano Banana is strong with clear, specific prompts. Vague prompts or tiny edits (e.g., “make it cooler”) can be ignored or misread. Testers noted the model follows precise instructions best.

Quote: “The longer I use it, the more disappointed I am,” one user wrote in a LiveMint report summarizing social complaints. “It may be due to Google’s strict security policy.”

How to fix Nano Banana prompts not working — step-by-step

Try these fast fixes — copy-paste or adapt them:

Be explicit and short. Use exact action words: “Replace background with studio grey; keep face and hair unchanged.” Example prompt:
“Create a 1/7 scale realistic figurine of the person in the photo on a grey studio base; preserve face details; no text.”
Avoid sensitive content. Reword anything that could trigger moderation (politics, violence, gore). If the tool blocks edits, try neutral phrasing.
Change style flags. Add style tokens like “photoreal, studio light, shallow depth” to guide the model. Example:
“Photoreal figurine, studio key light, shallow depth, no logos.”
Lower generation temperature / use the same seed. If using API or advanced settings, set temperature to 0 to get consistent outputs. Google community staff recommends prompt tweaks and stable settings for repeatable results.
Try again later or report. If servers are busy, wait a few minutes or send in-app feedback. Many support threads show Google asks users to report issues for fixes. Google Help

User tips and testing notes

Test small changes. Generate two results and compare.
Keep files simple (one clear face per image). Complex scenes lower success.
Follow community prompt guides (many outlets list tested templates).

Expert view: Android Authority’s hands-on found Nano Banana “far from perfect, but a lot of fun” — meaning it works well in many cases but still needs careful prompting.

Frequently Asked Questions

Why are my Nano Banana prompts not working?

Prompts can fail when Google’s safety filters block content, servers are overloaded, or the prompt is vague. Use clear, specific instructions and avoid sensitive topics. If problems persist, report the issue in the Gemini app.

How to fix Nano Banana prompts that are ignored?

Rewrite prompts to be specific: include style, subject, and exact changes. Try negative prompts like “no logos” and set generation controls (temperature 0) if using API. Also wait and retry if servers are busy.
