Ran Out of Nano Banana or Veo? How App Limits Work in 2026

You are halfway through a set of product shots and Gemini stops making images. Or Flow says you have no credits left for another Veo take. This guide explains how those caps are built, where Google and OpenAI publish real numbers (and where they do not), and what your options are when the allowance is gone.

The quick version: the Gemini and ChatGPT apps do not promise a fixed number of images per day. Gemini works with compute-based limits that come back every 5 hours, up to a weekly ceiling, and paid plans get a multiple of the free allowance. Only Flow lists exact credits per Veo clip. If you would rather not wait, Kadraris charges per result: Nano Banana Pro is from $0.07 per image and Veo 3.1 Fast is from $0.354 per video, with no plan to buy.

All plan figures below were read from Google and OpenAI help and pricing pages on October 4, 2026, with links to each page. Both companies reserve the right to change limits, so open the source before you pay for anything.

The one place with hard numbers: Veo credits in Flow

Flow, Google's video tool, is the exception. Every Veo generation there spends credits, and the Flow credits help page lists them.

Credits you get:

Credits a single clip costs:

Dividing one table by the other (monthly pool only):

• AI Plus: 10 Fast clips or 2 Quality clips per month.
• AI Pro: 50 Fast clips or 10 Quality clips per month.
• Daily 50 credits on their own: 5 Lite clips or 2 Fast clips, and not enough for one Quality clip.

Gemini app: multipliers instead of counts

In the Gemini app, Google describes limits as relative, not absolute. The Gemini Apps limits page says your allowance depends on how complex the prompts are, which models and features you call, and how long the chat is. What changes between plans is the multiplier.

Prices are from gemini.google/subscriptions and features from the limits page, both read on 2026-10-04.

How to read this:

• Free accounts can make Nano Banana 2 images. How many depends on what else you did in the same 5-hour window.
• The Pro image model starts at AI Plus. Google frames it as redoing an image with Nano Banana Pro.
• No paid plan, no video. The video help page now talks about generating video with Gemini Omni, while the plans page names Veo 3.1 Lite on AI Pro and Veo 3.1 on Ultra.
• Ignore "100 Pro images a day" claims. That count came from an older version of the help page. Google now publishes only multipliers, so I do not quote counts.

ChatGPT: limits exist, numbers do not

OpenAI publishes no daily image count for any plan. Here is how the ChatGPT pricing page words it (read 2026-10-04):

According to the Free tier FAQ, images have a separate limit from normal chat, and ChatGPT warns you when you reach it. That warning includes the reset time, which is the only trustworthy number for your own account. The "2-3 images a day on Free" figure you see quoted traces back to 2025 statements and user reports, not to the current pricing page.

Reset times side by side

• Gemini app: comes back every 5 hours until the weekly limit (source). After that, chat keeps working on the lighter Flash-Lite model.
• Flow, daily credits: 50 every day. Leftovers vanish at the end of the day (source).
• Flow, monthly credits: renewed at the start of each billing cycle. Leftovers do not carry over (source).
• ChatGPT: no fixed schedule. The limit message tells you how long to wait (source).

Subscription allowance or pay per result?

A plan gives you a monthly allowance for a flat fee. How many images it buys depends on how much you lean on everything else in the app. Paying per result flips that: there is no allowance at all, each image or clip has its own price.

When each one makes sense:

• Pick a plan if you use the whole Gemini package (chat, storage, Deep Research) and images are a side benefit.
• Pick pay per result if images and clips are the actual job and your volume jumps around, say 5 in a quiet week and 300 when a campaign starts.
• Remember what an API limit means. Through an API you face a rate limit (requests per minute, see Google's usage tiers), not an allowance. Nothing you paid for expires at month end.

Kadraris prices for the same models

Kadraris has no subscription and no daily quota. The minimum top-up is $10, the balance does not expire, and every price is visible on the Generate button before you send anything.

Things worth knowing about these prices:

• Batches are linear. 100 Pro images cost 100 × from $0.07 per image. Ten Fast clips cost 10 × from $0.354 per video.
• Veo is priced per clip. Each generation is 8 seconds, and 720p costs the same as 1080p.
• Image prices are for the base resolution. 4K output costs more. Plug your own counts into the AI cost calculator.
• Failures are free. If a generation fails, the hold on your balance is released in full, so you pay $0.

A concrete case: 50 Veo 3.1 Fast clips would eat the entire monthly Flow pool on AI Pro. On Kadraris the same 50 clips cost 50 × from $0.354 per video, paid as you make them, and whatever balance you do not spend is still there next month.

Moving a stuck project over

1. Create an account and add funds by card.
2. Open Kadraris Studio and choose Nano Banana Pro or Veo 3.1 Fast from the model list.
3. Paste the prompt you were using in Gemini. The cost appears before you press Generate.
4. For scripts and apps, call the same model through the API with your key:

curl "https://kadraris.com/v1/generate?wait=60" \
  -H "Authorization: Bearer $KADRARIS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "nano-banana-pro",
    "input": {
      "prompt": "Bakery window sign that reads \"Fresh bread 6 AM\", soft dawn light",
      "aspect_ratio": "4:5"
    }
  }'

The task comes back with estimated_cost before any work starts. More on Veo costs in Veo 3.1 API pricing, and on picking an image model in GPT Image 2.5 vs Nano Banana Pro vs FLUX.2.

Questions

Gemini refuses to make an image. Is it always the limit?

No. Check these in order:

• The 5-hour or weekly limit. Gemini shows a notice as you get close.
• Your plan. Nano Banana Pro and video need Google AI Plus or higher.
• A Workspace account. At work or school, your admin and license decide what is switched on.
• The prompt itself. Requests involving public figures or anything against Google's policies get declined no matter how much allowance is left. Rephrase instead of waiting.

If I skip a day in Flow, do I get double credits tomorrow?

No. Daily credits that you do not use are gone at the end of the day, and the monthly pool does not roll into the next cycle either (source). A Kadraris balance works differently: it stays until you spend it.

Can I try Nano Banana Pro in Gemini without paying?

Not according to the current limits page. Accounts with no plan get Nano Banana 2 within the standard allowance. The Pro model starts at AI Plus.

Is ChatGPT Pro really unlimited for images?

OpenAI calls it "Unlimited and faster image creation", but it still sits behind abuse guardrails. Plus is simply marked "Limits apply", with no number. Once you hit a cap, the in-app message is the only place that shows when it lifts.
