# Cezen AI Suite — Entry Level Installer

# Nexus One AI — Installer
|

# Usage:
|
||||
# sudo bash install.sh → Phase 1 (drivers + schedules reboot → Phase 2)
|
||||
# sudo bash install.sh --phase=2 → Phase 2 (all software, run after reboot)
|
||||
# sudo bash install.sh → auto-detect tier, Phase 1
|
||||
# sudo bash install.sh --tier=starter → Starter tier, Phase 1
|
||||
# sudo bash install.sh --tier=basic → Basic tier, Phase 1
|
||||
# sudo bash install.sh --tier=pro → Pro tier, Phase 1
|
||||
# sudo bash install.sh --tier=max → Max tier, Phase 1
|
||||
# sudo bash install.sh --phase=2 --tier=... → Phase 2 only (post-reboot)
|
||||
# sudo bash install.sh --software-only → install on customer-owned hardware
|
||||
# sudo bash install.sh --feasibility-only → scan hardware and exit
|
||||
# sudo bash install.sh --skip-model-pull → install Ollama without preloading models
