Under the Hood of AI Girlfriend Apps (2026): We Audited 217 Production JS Bundles to See What Models They Actually Run

Marketing pages call them "Vivid 3.0" or "Fluidity." Here are the real HuggingFace, Civitai, ByteDance, and Alibaba model IDs we extracted from their code—and the 11x retail markup.

Executive Summary (Verified Oct 2026)

AI companion apps rarely build foundational image or video models from scratch. By dissecting 217 production JavaScript bundles across Ourdream.ai, Candy.ai, Secrets.ai, and Kindroid.ai, we mapped their proprietary marketing labels directly to upstream open-weight and commercial APIs: `Tongyi Z-Image-Turbo` (`ZImageMoody`), `WAI-NSFW-Illustrious-SDXL v17` (`WaiIllustrious`), `bytedance/seedream-v5.0-pro/edit`, and `alibaba/wan-2.5`.

Retail Token Markup Over Wholesale GPU API Cost

1. The Complete Marketing-Name-to-Real-Model Rosetta Stone

When you click a style button inside a commercial companion studio, the frontend JavaScript sends an internal enum string to the backend inference router. Here is what our AST bundle analysis uncovered:

// Marketing Label → Actual Upstream Model Identifier (REA Verified)

Ourdream "Vivid 1.0–3.0"  → ZImage / ZImageMoody (Tongyi-MAI/Z-Image-Turbo 6B S3-DiT)
Ourdream "Fluidity"       → WaiIllustrious (WAI-NSFW-illustrious-SDXL v17 on Civitai)
Ourdream "Fusion"         → bytedance/seedream-v5.0-pro/edit
Secrets.ai Photo Edit     → bytedance/seedream-v5.0-pro/edit
Secrets.ai Motion Video   → alibaba/wan-2.5 + kling-video/v2.5-turbo/pro
Kindroid V8.5 Chat        → Dual Literary LLMs ("Lucidity" & "Lyric") + Cascading RAG

2. Wholesale Cloud GPU Cost vs. What You Pay in App Coins

Cross-referencing these exact models against Artificial Analysis wholesale rates explains the entire business model of AI companion apps. Generating 1,000 images on `Z-Image-Turbo` costs $5.00 wholesale ($0.005 per photo). Ourdream charges 5 DreamCoins (~$0.055), an 11x markup for providing a zero-setup browser UI. Meanwhile, 5-second video clips on `Alibaba Wan 2.5` or `Kling v2.5 Pro` cost ~$0.85 wholesale, which is why apps charge $1.30 to $2.00 per video clip.

Interactive Benchmark: Test the Models Yourself

Same Prompt, 3 Visual Engines: Image & Video Checkpoint Comparison

We sent identical photorealistic, anime, and 5-second motion prompts to see how each app’s underlying model performs—and what it actually costs per click.

Photorealistic Portrait

Shared Test Prompt:“Candid 35mm night portrait in a dimly lit Tokyo ramen shop, rain streaks and neon reflections on the glass window behind, holding a warm ceramic cup with both hands, natural skin texture, warm eye contact.”

Why we chose this prompt: This prompt stress-tests three failure points in companion image generators: (1) finger anatomy around a ceramic mug, (2) natural skin pores vs waxy plastic smoothing, and (3) background neon lighting without bleeding onto the face.
