The image + video engine behind a companion chat app.
Companion chat products live and die on message volume, not generation volume — most requests are text. Xavira is the part that fires when a user asks for a photo or a clip: fast enough not to stall the conversation, cheap enough to give away a first few for free.
This page is for developers building AI girlfriend or companion chat apps, where a persistent character talks with users and occasionally sends a photo or video clip. Xavira supplies that image and video layer over a REST API: fast photoreal (realistic-sharp-v1), sharper photoreal (realistic-v2) for a premium tier, or anime (anime-pure-v1) — all from one character, billed per credit.
Which models
Pick based on speed vs. sharpness — every model shares the same character and credit system.
realistic-sharp-v1RecommendedCheapest and fastest photoreal option — the right default when most users generate a handful of images per chat session.
anime-pure-v1Anime companions on the same API, same character primitive, same per-credit price.
realistic-v2Offer as a premium, sharper photo tier — same companion, better face and prompt adherence, at 2 credits instead of 1.
video-v1A short clip from the character’s existing avatar for the "send me a video" moment, no separate video pipeline to build.
Example prompts
Prose, not weighted tokens — Xavira adds the character’s traits and a quality prefix server-side.
“sitting cross-legged on the couch, oversized hoodie, warm lamp light, phone in hand, cozy evening at home”
“masterpiece, best quality, fitted crop top, low-rise jeans, looking over shoulder at viewer, soft indoor evening light, cowboy shot”
“bathroom mirror selfie, oversized t-shirt, damp hair, soft evening light, casual candid”

Real example
A companion chat platform: 1000+ characters, unlimited chat, image and video generation on request. It is a separate product from Xavira — same founder, no shared infrastructure or codebase — included here because the shape of its generation traffic (huge chat volume, occasional image/video request) is exactly the pattern this API is priced and built for.
