Stop burning on GPUs.
Start generating.
Running adult AI in-house is brutal: expensive GPU servers, fragile ML pipelines, payment processors that drop you every few months, never-ending maintenance. We've already absorbed all of it. You add a single integration and ship.

UNCENSORED · BLURREDSelf-host vs. plug us in.
Production-grade GPU rental on a reputable cloud runs $1.50–$3/hour. At scale you stack always-on workers, ops engineers, content-moderation APIs, and the payment-processor cancellation cycle on top. Side-by-side, aligned with each Xavira plan:
How we calculated this +
Xavira side: pure per-credit math at the cheapest pack rate the volume qualifies for: Starter 4.9¢, Builder 4.4¢, Scale 3.9¢, Volume 3.4¢, Enterprise ≤2.8¢.
Self-host side, GPU rental: production-grade GPU on a reputable cloud at ~$1.50/hour for L40S-class, ~$2–3/hour for A100/H100 at higher tiers. Workers stay always-on (you can't tolerate cold-start latency for paying users). One worker handles ~3,500–7,000 imgs/day at warm 50–100% util.
Self-host side, ops + moderation: a fractional ML/ops engineer scales linearly with volume (0.2 FTE on Starter, 1 full FTE on Enterprise). Content-moderation APIs (text + vision) add ~$0.005/image at scale. Adult-merchant payment-processor cuts run 6–10% vs Xavira's bundled rate, plus periodic re-onboarding when a processor drops you (3–6 month cycle).
What's still NOT in the column: the 3-month upfront engineering build, R2/S3 storage + egress, NSFW vision-classifier licensing at enterprise scale, on-call rotations. Real-world DIY all-in is often 1.5–2× the numbers shown.
What you can build.
One character. Any scene. Same face.
Every character your users create is remembered. Drop the same character into ten different prompts and they look like themselves in all ten. Other tools regenerate the face from scratch every time; that's how the "drift" you see on most AI sites happens. We don't.
- Identity locked across thousands of follow-up images
- Works with a trait combo OR with a photo your user uploads
- Under 5 seconds per image, same speed every time
HD costs the same as SD. No paywalled "premium" tier.
Six curated resolution presets: portrait, landscape, square; SD or HD on each. Every preset is 1 credit. No upcharge for HD, no "premium" quality tier you have to upsell. Default is SD-portrait (560×720) for fast, cheap prototyping; flip to HD-portrait (896×1152) when you want maximum detail.
- 6 presets · same 1-credit price across all of them
- HD lives behind a single parameter, not a paywall
- Always-on sharpening pass on every gen, every preset
The whole prompt vocabulary, yours.
The closed-enum traits lock identity. Everything else lives in the free-text prompt: eye color, freckles, beauty marks, makeup, tattoos, piercings, outfit details, hair styling, lighting setup, mood, framing, camera, location. No 25-slider UI. Natural language, anything you can describe.
- Eyes · blue / hazel / amber / freckles
- Makeup · winged liner / red lip
- Tattoos · sleeve / line tattoos
- Outfit · sweater / dress / lingerie
- Lighting · golden hour / studio
- Pose · candid / editorial
- Camera · 35mm / shallow DoF
- Location · cafe / bedroom / rooftop
Photoreal or anime. One integration.
Your users pick photoreal portrait or anime / stylized illustration. Both at 1 credit per image. Both with the same identity-consistency. No separate integration, no separate billing, no separate quotas.
- Photoreal: sharp, photographic, magazine-style portraits
- Anime: vibrant, stylized, illustration-quality
- Pre-tuned: no settings for your users to get wrong
Your users' characters, in motion.
Any character that exists in your app can be brought to life with a short motion clip. Slow head turn, gentle smile, hair flowing in a breeze: the user describes the movement, we deliver the clip. 5 credits per video.
- ~5-second clips, smooth motion
- Async: you tell us where to deliver the result, we send it
- Same character identity carries through into the video

Three steps. No setup.
From signup to your first generation, end-to-end, in about three minutes.
Sign up & mint a key
Email or Google/Apple OAuth. Generate an API key from the Profile page. Get starter credits to try before you pay.
Create a character
Pick traits (gender, ethnicity, age, hair, build) or upload a reference image. We generate the avatar and cache the face identity on disk.
Generate anything
Drop the character ID into any prompt. Same face. Any scene. Any outfit. Any lighting. Repeat as often as you want.
Photoreal. SFW or NSFW, your call.
One model, one integration, one per-credit price. Switch from editorial portrait to adult content with a prompt change, no separate endpoint, no separate billing, no model swap. Identity stays consistent across both.
Editorial · lifestyle · portrait
Photographic quality at 1 credit per image. Mix of characters, the brown-haired set on the bottom row is one character in three scenes, showing identity-consistency.
Uncensored · adult · photoreal 18+ blurred
Same model, same 1 credit, same per-character consistency. We blur the preview here so the landing stays SFW. Register to see the uncensored output running live in your portal playground.

What it actually takes to run this yourself.
Spinning up adult AI image and video generation in-house looks deceptively simple from the outside: "download a model, throw it on a GPU, done". Here's what really happens:
Before your first paid customer
Setup a GPU pool. Wire up identity persistence. Build text and vision content filters. Implement permanent image and video storage. Build signed webhook delivery with retries. Wire up billing, credits, refunds. Get all of it through testing.
Just to keep GPUs warm
Production-grade GPUs run $1-5 per hour. To keep latency reasonable for your users you can't scale to zero; that's a permanent monthly bill before a single end-user generates anything. Add storage, bandwidth, payment processing.
Or your product dies
Model releases break everything every few months. Libraries silently bump version requirements. CUDA drivers update. Queues get throttled. Cold starts balloon. Without dedicated ML ops people, your stack rots, and so does your product.
Payment processor drops you
Adult-content merchants get cancelled by Stripe, PayPal, and most banks routinely. Every cycle means re-onboarding to a new processor, updating webhooks, re-implementing fraud handling. We've solved this once, for everyone.
We've already eaten all of this. You skip 3 months, $30k+ of upfront spend, and the permanent operational burden.
From 3.4¢ per image.
No subscriptions. No monthly minimums. No "seats". No auto-renew. Buy a credit pack, use it when you want, top up when you run out.

Frequently asked questions.
Is adult content actually allowed?
Yes, adult content is allowed by design. Consensual sexual imagery between adults is what the API is built for. We block specifically for CSAM, non-consensual content, identifiable real persons without consent, bestiality, extreme violence, and a handful of other categories. Full list at Moderation Policy.
Do you train on my Customer Data?
No. Your prompts, reference images, and outputs are never used to train our models or any third-party models without your explicit, separately-obtained consent. Full data flow in the Privacy Policy + DPA.
Why no Stripe? Why crypto?
Adult-content merchants get cancelled by Stripe routinely. We use Finby (SEPA + BTC + USDT + USDC) as our payment processor specifically to provide a stable settlement rail. Prepaid only. See the Refund Policy.
How do you keep the face consistent?
When a character is created, we capture an identity fingerprint from the base image and remember it for that character. Every subsequent generation reuses that fingerprint instead of guessing the face again. Result: the same person across thousands of follow-up images, and no extra wait time per generation.
Can I upload my own face / reference image?
Yes. POST /v1/characters accepts either trait-mode (closed enums) or reference-image-mode (an HTTPS URL up to 20 MB). We rehost the reference on our R2 bucket so the avatar URL is permanent. From that moment, every generation against this character carries the identity from your reference.
How fast is it?
Most images finish in under 5 seconds. Videos take about a minute and a half. We keep a warm pool of GPUs so your users rarely hit a cold start. Real-time numbers visible on your dashboard once you sign in.
What happens when moderation blocks a request?
HTTP 422 moderation_blocked with a tier + category in error.details. No credit charged. For wrongly-blocked gens, customers can appeal via /moderation.
Why not just run the models myself?
You can. It costs ~3 months of engineering work to wire up, $1,500-$3,500 a month in always-on GPU compute (you can't scale to zero or your latency goes through the floor), 2-3 ML-ops engineers to maintain, and every 3-6 months your payment processor cancels your adult-content account and you start over. Most teams that try it migrate to us inside a year. We've already eaten all of that; you skip it.
Is there a free tier?
Sign up is free and gets you a small starter Credit balance so you can exercise the full API end-to-end before paying anything. There's no card on file, no trial countdown, no auto-charge. You buy a Credit pack when you actually want to ship.
What does "no subscriptions" actually mean?
You never have a recurring charge. You buy Credit packs ($20 / $90 / $400) when you want, you use them when you want, you top up when you run out. No monthly minimum. No annual commitment. No "seats". No auto-renew. Credits live 12 months from the purchase date.
