In short: these messages mean Google Flow wants you to slow down. Stop sending, wait, and come back at a calmer pace. There is no safe way around them, and trying again and again usually makes the wait longer. For long lists, space your prompts out, take breaks between files, and run one list at a time.
Google does not publish Flow's exact limits, and they can change. What follows is based on the messages Flow shows and on what many users report on Google's AI developer forum.
The messages
| Flow says | What it means |
|---|---|
| You're requesting generations too quickly. Please wait a moment and try again. | Too many requests in a short time. Usually the lighter of the two, but users report it can last from minutes to several hours. |
| We noticed some unusual activity… | A stronger stop on the account. Generations fail until it is lifted, and users report it can last much longer. |
| Not enough credits | Not a speed limit: your account has run out of credits for that model. |
If you use Flow in Arabic, it shows the same messages in Arabic.
What to do now
- Stop sending. If a list is running in Prompt Batch, press Stop.
- Wait. Give it at least an hour before trying again. After "unusual activity", wait longer.
- Don't retry in a loop. Pressing Generate again and again, or opening another tab or browser to keep going, tends to make the stop last longer.
- Test with one prompt by hand. When it works again, start back slowly.
- Still stuck after a day? Use the Feedback option inside Flow. Google's forum moderators point Flow users there.
How to see them less
- Space your prompts out. In Prompt Batch, raise Seconds between prompts to 30 or more for long lists. Slower runs are gentler on your account.
- Take breaks. Run one file, then rest before the next one, instead of running lists back to back all day.
- One list at a time. Don't run several lists in parallel, in several tabs or on several computers, on the same account.
- Make each prompt count. Test a few prompts first and fix them before running fifty. Fewer retries means fewer requests.
- Send by hand if you prefer. In Prompt Batch, turn on I press send myself (safer): the extension prepares each prompt and you press Flow's send arrow yourself.
What Prompt Batch does for you
- It waits at least 10 seconds between prompts, a little different each time, and never less, even if a setting is changed.
- It stops the whole list on its own when Flow reports unusual activity, and tells you to wait about an hour.
- It stops on its own when your Flow credits run out.
- On other errors it marks the row as failed and moves to the next one. So if you see "requesting generations too quickly" during a run, press Stop yourself and wait.
Prompt Batch does not get around Flow's limits, and it is not made or endorsed by Google. It does in your own account what you would do by hand, and you are responsible for following Google's terms.
Questions
Is there a way around the limit?
No, and we don't recommend looking for one. The limits protect Flow and your account. The only reliable fix is to wait and come back at a calmer pace.
How long does it last?
Google does not say. Users report anything from a few minutes to several hours, and sometimes longer after "unusual activity". Waiting without retrying is what helps most.
Does it only happen with extensions?
No. Users report seeing it while working by hand too, especially after many generations close together.
Will my account be safe with Prompt Batch?
Prompt Batch works at a calm pace and stops on Flow's strongest warning, but no tool can promise how Google will treat an account. Use it at a pace you are comfortable with, and follow Google's terms.
