The short answer

Flexible ads (Meta's flexible ad format) take up to 10 images and videos in one ad and let delivery pick single image, video or carousel per person. Dynamic creative mixes your assets into combinations and, since June 2024, may no longer be available for Sales or App promotion. Single ads give the cleanest read. On our board, winning image ads run 2.8 versions on average against 1.4 for videos.

The three options, side by side

Meta has renamed and merged these features several times, so we checked the current help center pages (October 2026) before writing this. Here is what each one is today.

Flexible ads: what Meta says

Per Meta's help page, when you choose Flexible as the format, "you can select up to 10 images and videos in a single ad campaign" (the format itself is chosen at the ad level), and the delivery system "will automatically determine what media or media combination, such as single image, video or carousel, to show to people". You can group certain media with different combinations of text.

Three details that matter in practice:

  • Objectives. The format is listed for Traffic, Engagement, Sales and App promotion, with some conversion location limits (for Traffic, website; for Sales, website, app or message destinations).
  • Availability. The same page says the feature "may not be available to you" and points to multi-media ads and creative customization if it's missing from ad setup. Interfaces differ by account.
  • Not the same as flexible media. Meta also has a feature called flexible media, which lets a single image or video run in extra placements. Meta's own note: flexible media decides whether one asset can be used in more placements, while the flexible ad format chooses among several assets and formats.

Dynamic creative: still here, but not for sales

Dynamic creative takes your elements (images, videos, headlines, primary texts, CTAs) and combines them automatically. Meta's create guide lists up to 10 images and/or videos and up to 5 headline and 5 CTA options.

The key line from About dynamic creative: "as of June 2024, you may no longer be able to use dynamic creative when creating ad sets on ads manager when you select sales or app promotion as your objective." Meta recommends the flexible ad format for a similar result. Dynamic creative also caps out at 1,000 ads per account and doesn't work with multi-language ads or asset customization.

Meta is also direct about testing: because results are aggregated across variations, "using dynamic creative as a substitute for split testing is not recommended."

Advantage+ creative is a different layer

People often lump Advantage+ creative in with the two above. It is not a format. It is a set of enhancements Meta can apply to whatever ad you build: brightness and contrast, music, text overlays, image animation, video effects, CTA changes, AI image and text variations, and more. Meta says some enhancements "may be turned on by default" and that "the media and text you upload may be adjusted".

That has a testing consequence. If enhancements are on, the ad people see may not be exactly the ad you approved, and two "identical" test ads may be served differently. For a clean creative test, check the enhancements section and the advanced preview, and switch off what you don't want. Meta's page on turning off enhancements notes some can only be changed in the advanced preview.

What the winning ads on our board suggest

From the outside, the Ad Library doesn't tell you which format an ad uses. It does show how many versions an ad runs. On the Ad Radar board (October 9, 2026: 2,443 live Meta ads above $50k in estimated spend), versions split sharply by format:

FormatAdsAvg. versions per adRuns 2+ versionsRuns 5+ versions
Image4752.843%76 ads (16%)
Video1,9681.425%45 ads (2%)

2.8

average versions per winning image ad

1.4

average versions per winning video ad

16%

of winning image ads run 5+ versions

Image winners carry about twice as many versions as video winners. Statics are cheap to multiply (new headline, new photo, new background), and multi-asset setups like flexible ads or dynamic creative make that easy. We can't confirm which setup each brand uses, so read this as a pattern in how statics are run, not proof of a format.

Version count also tracks the top tier for both formats. Among images, 3.7% of single-version ads reach Ad Radar's top tier, against 43% of those with five or more. Variants are part of the winner score, so the gap is partly built in. More on reading versions in ad variants as a scaling signal.

Which to use when

Use single ads when you need to learn. New concepts, hook tests and anything you will make a decision on. One asset per ad gives one clean result. This is the default for the testing stage of the creative testing framework.

Use flexible ads when you need to scale a set you already trust. Put a proven video, its static version and two cuts in one flexible ad and let delivery pick. You give up per-asset clarity in exchange for fewer ads to manage and placement-by-placement format choice.

Use dynamic creative only on objectives where it's still offered, and only for element mixes (headline x image x CTA) on non-sales goals, such as traffic to a quiz or lead form.

Treat Advantage+ creative enhancements as a separate decision for every ad. Leave them on where you want Meta to experiment, turn them off where you need a controlled test.

A setup you can copy

TESTING CAMPAIGN (learn)
  Ad set: broad, highest volume
  Ads: SINGLE image/video ads, one concept or hook each
  Advantage+ creative: review enhancements; turn off any that change
                       the message you are testing
  Read: 2-3x target CPA per ad (rule of thumb)

SCALING CAMPAIGN (spend)
  Ad 1: winning video as a single ad (keep post ID / social proof)
  Ad 2: FLEXIBLE ad with the winner's family:
        - full video, 15s cut, 30s cut
        - static image with the strongest line
        - group text: original copy + 1 short version
  Advantage+ creative: enhancements on where tested and acceptable

NON-SALES (e.g. traffic to a quiz)
  Dynamic creative allowed: 2-3 images x 3 headlines x 2 CTAs

Figures marked as estimated spend come from Ad Radar's model of engagement on public Meta Ad Library ads. They are estimates, labeled as such, and are best used to rank ads against each other.

Questions

What is the flexible ad format on Meta?

It is an ad format where you upload up to 10 images and videos to one ad, and Meta's delivery system decides whether to show a single image, a video or a carousel to each person based on placement and audience. You can group media with different text. Meta lists it for the Traffic, Engagement, Sales and App promotion objectives.

Is dynamic creative going away?

Partly. Meta's help center says that as of June 2024 you may no longer be able to use dynamic creative when creating ad sets with the Sales or App promotion objective, and recommends the flexible ad format instead. Existing dynamic creative campaigns were not affected at the time. Other objectives can still use it.

What is the difference between flexible ads and Advantage+ creative?

The flexible ad format chooses among the media you upload and the format to show them in. Advantage+ creative is a set of enhancements applied to an ad, such as brightness adjustments, music, text overlays or AI-generated variations. Some enhancements are on by default. You can use both on the same ad and turn individual enhancements off.

Should I use flexible ads for creative testing?

Not for a clean test. Like dynamic creative, flexible ads report results at the ad level, so you can't easily say which asset won. Use single-asset ads when you need to know which concept or hook is better, and flexible ads to scale a set of assets you already trust.
