Flagship smartphone users are getting a significant boost to their phone’s local processing intelligence. If you own a OnePlus 15 or an OPPO Find X9 Ultra, a major update is now rolling out to your phone’s system system intelligence engine.
OPPO and OnePlus have begun pushing comprehensive feature updates for their core On-Device AI Models, which handle offline artificial intelligence tasks without sending sensitive telemetry to remote cloud servers.
The fresh software patches bring noticeable upgrades to existing system-level Large Language Models (LLMs) and Multimodal engines. Here is everything you need to know about the new packages, their download sizes, and how to get them installed on your device today.
What’s Included in the Update?
The system intelligence hub relies on distinct machine learning packages to keep user data private while performing complex processing locally. The latest firmware updates update two primary components:
┌────────────────────────────────────────────────────────────────────────┐
│ ON-DEVICE AI MODEL UPDATE │
├───────────────────────────────┬────────────────────────────────────────┤
│ Model Component │ Package Size / Action │
├───────────────────────────────┼────────────────────────────────────────┤
│ Large Multimodal Model │ ~2.2 GB (New Installation / Upgrade) │
│ Aesthetics LLM │ ~644 MB Update (Full Size: ~1.3 GB) │
└───────────────────────────────┴────────────────────────────────────────┘
1. Large Multimodal Model (~2.2 GB)
Size: ~2.2 GB
Role: Serves as the primary underlying architecture for cross-modal understanding across system features.
Functionality: Powers context-aware visual searches, voice query understanding, real-time image analysis, and local generative text parsing without relying on an active internet connection.
Installation Time: Takes approximately 50 to 60 minutes to complete download and background compilation depending on connection speed.
2. Aesthetics LLM (~644 MB Patch / ~1.3 GB Total)
Size: ~644 MB differential update package (brings total footprint to ~1.3 GB)
Role: Drives photo gallery intelligence, automatic scene curation, and intelligent image scoring.
Functionality: Automatically curates photo memories, isolates blurry duplicate shots, organizes album highlights, and suggests lighting, exposure, and color corrections inside the stock Photos app.
Installation Time: Requires roughly 15 minutes to complete downloading and local indexing.
Why Local AI Processing Matters
Unlike traditional cloud-based AI tools, these updates execute routines using the Snapdragon’s local Neural Processing Unit (NPU). Keeping models running directly on-device delivers key advantages:
Complete Data Privacy: Photos, personal logs, and text data processed by the Aesthetics LLM or Large Multimodal Model never leave the physical storage of your phone.
Zero-Latency Offline Access: Key tools operate seamlessly even when connected to flight mode or spotty mobile network zones.
Battery & Power Efficiency: Offloading processing to local hardware NPUs avoids constant Wi-Fi/5G data transmission, preserving background battery performance over prolonged sessions.
This roll-out aligns with ongoing system optimization efforts across both brand ecosystems. Users keeping track of system releases can also explore how ColorOS 17 builds surface for OPPO Find X9 Series & OnePlus 15, showing how both brands continue to unify their core software architectures.
How to Check and Install Updates
To ensure your device is running the latest AI features, follow these steps:
Open Settings on your OnePlus 15 or OPPO Find X9 Ultra.
Scroll down and select System & Apps (or search for On-device AI models in the top search bar).
Tap on On-device AI models.
Look for pending updates next to Large Multimodal Model or Aesthetics LLM.
Tap Update or Install.
Tip: Make sure Automatically download and update over Wi-Fi is toggled ON to receive local model improvements as soon as they drop.
Final Thoughts
As smartphone manufacturers move toward local intelligence, periodic updates to machine-learning models are becoming as essential as traditional security patches. With these latest packages installed, your OnePlus 15 or OPPO Find X9 Ultra will handle scene classification, photo organization, and system assistant tasks faster and more accurately—all while keeping your data fully private on your device.
