XenLook 4b-Ko combines XenLook's XenLook 4b-Ko Korean dialogue model with culture LLM lanes and Harness orchestration for 100 public agents.

We do not claim benchmark superiority without published audits. Routing details: /llm · /ai-policy.
EDGE SECURITY · VERIFIABLE
Every public XENLOOK origin uses nonce CSP, HSTS preload, and Secure cookie defaults. Anyone can re-verify on Mozilla Observatory.

Observatory A+ grades HTTP security headers only; it does not certify absence of app vulnerabilities or breaches.
Mozilla HTTP Observatory (A+) measures HTTP security headers and TLS config; SSL Labs (A−, target A+) measures certificate chains and cipher suites. Different methodologies — both are published; items below target include re-verify links.
FREE THIRD-PARTY SCANS
Independent free scans on xenlook.com — we show both targets met and honest in-progress scores (e.g. SSL, performance). Not formal certification.

XenLook operates C2PA Certification Authority and Generator Product programs under executed agreements (2026-06-13). Trust List and CPL listing are not claimed until C2PA confirms.
Plain-language guide
C2PA is a worldwide standard — like a nutrition label for digital photos and videos. It helps people see if content was made by AI and who signed it.
Honest note: XenLook runs a pilot certificate authority in Korea. We are NOT on the official C2PA Trust List yet. Our certificates work in our pipeline and for learning; global trust comes after official listing.
01When you save a picture with C2PA, a small sticker (Content Credentials) travels with the file. Apps that understand C2PA can read: who made it, whether AI was used, and who signed it.

02A certificate is like an ID card for your signing tool. XenLook CA can issue claim-signing certificates so your generator can attach trustworthy labels to media.

03You generate a key pair on your computer. You send us only a CSR (a request). We never ask for your private key. If someone steals your key, tell us immediately so we can revoke the certificate.

CONTENT AUTHENTICITY · CAI
XenLook Inc. is a member of the Content Authenticity Initiative (CAI), the industry coalition behind the C2PA standard for content credentials and provenance.
contentauthenticity.orgCAI membership supports our C2PA-aligned signing infrastructure. It does not imply C2PA Generator certification, Trust List CA status, or Adobe Content Credentials Inspect “trusted” status.
CLOUD SECURITY · CSA
XenLook Inc. is listed on the CSA STAR Registry (2026-06-12) with a Level 1 self-assessment documented in CAIQ v4.1. Registry: cloudsecurityalliance.org/star/registry/xenlook-inc
STAR Level 1 is a self-assessment; it is not the same as Level 2 third-party attestation or CSA community membership alone.
AI GOVERNANCE · IMDA
XenLook Inc. completed a voluntary self-assessment under the IMDA AI Verify Testing Framework (11 principles) for ConvAI, Novel, Music, Image, Video, 3D, and Work Studio. We maintain governance docs, a 72/72 safety harness, and a GenAI Summary Report.
Voluntary self-assessment—not an IMDA official certification or registry listing.
Most people use on.xenlook.com in the browser (default). Optionally install Companion like a game to run XenLook 4b-Ko on your PC — chats stay on your drive with faster local replies.
What is the difference?
Web on (default) — browser only. Chats go through XenLook cloud (internet round-trip).
Companion (optional) — install like a game on your PC. Saves stay in your folder; everyday chat runs on your GPU locally.
Local storage is opt-in. You must agree in on chat before it turns on. Local chat text is not stored in XenLook company chat database.
Why install?
Not streaming (web) — installed like a game. Download the app and 4B model; chats stay on your PC like a save file.
For local turns (L0/L1), IDs and account numbers are not stored in XenLook server chat DB. PC security and backup are yours.
No cloud round-trip — 4B inference on localhost. Short replies without internet wait or shared server queue.
Install Companion + active vault (daemon verified): 10% off Resident, Citizen, Signature, Royal monthly plans.
After consent, chat history stays on your computer. Plaintext is not saved to XenLook server chat DB.
Choose the folder in on chat settings. Chat files are written there.
XenLook Korean dialogue model (4B, released 2026). Runs on your PC. Same product family as web on.
Default is web on (cloud). Companion is optional; local mode never turns on without consent. 10% paid-member discount applies after vault + daemon heartbeat verification. Cloud used only on opt-in reasoning turns.
