How to Create a Consistent AI Influencer (Same Face Every Post)

A consistent AI influencer comes from one locked reference image, not from a clever prompt. Generate the face once, keep that single image, and upload it as a reference every time you make a new shot — then describe only what changes. On VdoBloom that means Nano Banana 2.1 at 3 credits for 1K with up to 14 reference images, a character sheet for the angles you will need, and pose variations at 6 credits an image when you want several shots of the same person in one run.

Why an AI influencer drifts between posts

Image models do not remember anyone. Every generation starts from zero and interprets your words freshly, so “a woman with dark hair in a beige jumper” gives you a slightly different woman each time — different face shape, different hair, different age. The drift is not noise you can prompt away; it is the model doing exactly what you asked, from scratch, again.

The fix is to stop describing the person and start showing them. A reference image carries the identity that words cannot. Prompts then describe the scene, the pose and the light, and leave the face alone. That is the whole method, and every step below is a way of protecting one chosen reference.

Step 1: generate the face once, and choose carefully

Decide the position before the face. A beauty influencer, a fitness creator and a home-cooking channel need different people. Write down the age range, the look, the wardrobe register and the setting — these become the fixed part of every future prompt.
Generate the portrait. In the image generator, describe the person and the shot: framing, angle, lens feel, light and background. Aim for a clean, evenly lit, front-facing or three-quarter shot with nothing over the face.
Keep the cost low while you experiment. Muse Image is 1 credit and Seedream 5 Flash is 2; Nano Banana 2.1 is 3 credits at 1K, 4 at 2K and 6 at 4K. There is no reason to iterate at 4K on a face you have not settled on.
Stop when the face is right, and save the file. From here on, that image is the influencer.

You can also build the person inside the UGC Ad Creator, which generates several influencer images at once from settings — gender, age, ethnicity, background, style, camera placement, coverage and aspect ratio — and then carries the image you pick through a product shot and a talking video. See the AI influencer generator page for that route.

Step 2: build a reference set before you need it

A single front-facing portrait is enough for a front-facing feed. The moment you need a side view, a back view or a walking shot, one image runs out. Two VdoBloom tools cover that gap:

The character sheet at the character sheet tool produces front, side and back views of the same person.
Pose variations turns one prompt into several shots of the same person, changing pose, camera, setting and framing while the person, outfit and body stay fixed. It runs 2, 4 or 6 variations at a time, and the default model is Nano Banana at 6 credits per image.

Do this early. Building a reference set from a face you are still unsure about wastes it. More detail is in keeping a character consistent across images, and the character sheet guide covers the angles themselves.

Step 3: write one fixed descriptor block and never change it

Consistency comes from a frozen paragraph you paste into every prompt, followed by the variable part. The block describes what must not change; the variable part describes the shot.

The fixed block, as an example:

“A woman in her late twenties, dark brown wavy shoulder-length hair, warm light-brown skin, small mole on the left cheek, wearing a plain oatmeal knit jumper. Keep the face, hair and skin tone exactly as in the reference image.”

Then the variable part changes per post: “Sitting at a wooden kitchen table with a coffee cup, morning window light from the left, three-quarter shot at eye level, shallow depth of field.”

Reuse the exact wording every time. Retyping the block from memory is how variation creeps back in.

Step 4: upload the same reference every time

This is the step people skip. The prompt block anchors the description; the reference image anchors the identity. Upload the chosen portrait every single time, even for a shot that seems obvious. If the reference is a real person rather than a generated one, get their agreement first.

Reference capacity varies, and it decides which model you should use for a consistent feed:

Model	Reference images it accepts	Credits
Nano Banana 2.1	Up to 14	3 / 4 / 6 by resolution
Nano Banana 2	Up to 14	15 flat
GPT Image 2.5 Flare and Sunburst	Up to 16	3 / 5 / 8 by resolution
Seedream 5 Lite	Up to 14	6
GPT Image 2	Up to 10	3 / 5 / 8 by resolution
Riverflow 2.0 Pro	Up to 10	18 at 1K and 2K, 27 at 4K

Multiple references are useful rather than redundant: the portrait plus a full-body shot plus the character sheet gives the model the face and the silhouette, which is what keeps a walking or seated shot from turning into a different person.

Step 5: keep wardrobe, light and location in a second locked block

Feeds look consistent when the non-human variables are consistent too. Write a second frozen paragraph for the look — “warm natural light, muted neutral palette, soft grain, 50mm perspective” — and reuse it. Changing the light every post is a bigger visual break than a slightly different nose.

Step 6: fix drift with an edit, not a re-roll

When a shot comes back almost right but the face has moved, do not regenerate. Upload the good face and the drifted shot to the image editor and ask for the one change you want. A reference-based edit holds the identity far better than a fresh generation with the same words, because it has both images in front of it.

Prompt examples

Close-up for a caption post: “Head-and-shoulders portrait of the person in the reference image, looking slightly off camera, soft window light from the right, plain warm-grey wall. Keep the face, hair and skin tone exactly as in the reference.”
Product-in-hand shot: “Waist-up shot of the person in the reference image holding a glass bottle at chest height in a bright kitchen; keep the face and outfit unchanged, product label facing the camera, shallow depth of field.”
Street walk for a Reel: “Full-body walking shot of the person in the reference image on a city pavement, mid-step, golden-hour side light; keep the outfit from the reference, 35mm perspective, motion in the background.”
Seated talking head: “The person in the reference image seated at a desk facing the camera, arms relaxed, softbox light from the front-left, tidy study background. No text, no logos.”
Outfit change without a face change: “Same person as the reference image, now wearing a charcoal blazer over a white shirt, against a plain studio backdrop, even light. Keep the face, hair and skin tone identical.”

Note the pattern: every example names what must not change, and none re-describes the face.

Common mistakes

Re-describing the face in words instead of uploading it. The most common cause of a feed that looks like a different person every day.
Generating at 4K while the face is still undecided. Nano Banana 2.1 costs twice as much at 4K as at 1K; settle the face cheap, render the winner high.
Changing the light and the location every post. An identical face will still not look like one creator.
Using a full-body shot as the only reference. The face occupies too few pixels; pair it with a portrait.
Skipping the exclusions. Add “no text, no logos, no watermark” — invented lettering makes a polished feed look fake faster than anything else.
Forgetting the disclosure. These are generated faces — if the account presents itself as a human creator, say so.

Which model to pick

Default: Nano Banana 2.1 at 3 credits for 1K, up to 14 references, 15 aspect ratios including the vertical crops a feed needs.
Best identity retention: GPT Image 2.5 Flare or Sunburst, 3 to 8 credits, up to 16 references.
Cheapest iteration: Muse Image at 1 credit, fixed 2K, 10 references on the edit side.
Multiple shots in one run: pose variations, 6 credits an image on the default model, 2 to 6 variations at a time.
Many angles of one character: the character sheet tool, which returns front, side and back.

Credits are priced before every run. New accounts get 10 free credits with no card — three 1K portraits on Nano Banana 2.1, or ten on Muse Image. The Lite plan is $15 a month for 300 credits, or $10 a month billed yearly; one-time packs start at $10.39 for 200 credits and never expire; India plans start at ₹199 a month. See the pricing page.

Frequently asked questions

How do I keep an AI influencer’s face consistent?

Lock one reference image and upload it with every generation, paste an identical description of the person into every prompt, and change only the scene, pose and light. A model that accepts many references helps: Nano Banana 2.1 takes up to 14, and GPT Image 2.5 up to 16.

Do I need a character sheet?

Only if you need angles you cannot describe — a side view, a back view, a full-body silhouette. The character sheet tool returns front, side and back views of one person, which make better references than a single portrait.

How much does it cost to make an AI influencer?

The face is cheap: 1 credit on Muse Image, 2 on Seedream 5 Flash, or 3 on Nano Banana 2.1 at 1K. The 10 free signup credits cover a first portrait and several variations. Pose variations cost 6 credits an image on the default model.

Can I use an AI influencer for commercial posts?

Yes. Output from a paid plan is watermark-free with commercial rights. Keep the disclosure honest if the account presents itself as a human creator — do not imply a generated person is a real, unedited one.

How do I get several poses of the same person in one run?

Use pose variations. Give it a reference image, a base prompt and a variation strength — subtle locks the identity and changes only the pose, bold allows more cinematic diversity — then choose 2, 4 or 6 images. The person, outfit and body stay fixed while pose, camera, scene and framing change.

Open the image generator and make the first portrait of your character — the 10 free signup credits are enough to settle a face before you commit.
