## Why it is here

Quinn Nelson (22:49) after a summer of testing the iOS 27 Siri AI beta: how it works under the hood (AFM 3 Core models, per the description) and how to use it best. 294k views.

## Description (written by Gemini from the video)

**Summary**  
Quinn Nelson of Snazzy Labs reviews his summer testing Apple’s overhauled Siri AI and Apple Intelligence architecture in iOS. He breaks down the underlying Apple Foundation Model (AFM) tier system, explores why Siri frequently fails or hallucinates, inspects the backend logs via the Apple Intelligence Report, and demonstrates workarounds using App Intents and automated Shortcuts.

**What is shown**  
* **[00:20]** Siri failing to query Instagram follower information directly.  
* **[01:14]** Breakdown diagram illustrating how LLMs tokenize text and predict next tokens.  
* **[02:51]** Graphic overview of the third-generation Apple Foundation Models (AFM 3 Core, Core Advanced, Cloud, Cloud Image, and Cloud Pro).  
* **[04:22]** Camera-based visual lookup analyzing a jalapeño plant and providing watering advice.  
* **[05:46]** Prompting Siri for Instagram statistics, resulting in a hallucinated view count cited from a blank iMessage link.  
* **[07:58]** iOS Settings walkthrough showing local semantic indexing in Spotlight and App Intents toggles per app.  
* **[10:46]** Siri retrieving birthdays mentioned in messages, but refusing to update contact cards.  
* **[11:18]** Asking Siri to text the presenter's brother, which sends only the single letter "A" without confirmation.  
* **[12:04]** Siri refusing to read or summarize a direct URL due to system prompt restrictions.  
* **[13:23]** Inspecting the raw text logs and system prompt within `Settings > Privacy & Security > Apple Intelligence Report`.  
* **[14:47]** Testing Siri offline in Airplane Mode: basic timers, alarms, and flashlight work, while seven other simple requests fail.  
* **[16:48]** On-screen context demos: tapping messages, emailing calendar attendees about running late, and evaluating an eBay listing for a Nintendo 3DS XL.  
* **[17:50]** Camera visual query demos: identifying a Charli XCX *brat* vinyl and opening Amazon, identifying a moss rose, and calculating a 20% tip split from a receipt.  
* **[19:33]** Multi-part trip query calculating rental car and estimated fuel costs between Durham and Wilmington, NC.  
* **[20:41]** Siri falsely confirming a Rivian R2 was unlocked when the vehicle was unreachable, and mistakenly enabling climate control on a Kia EV9 via Apple CarKey instead of Rivian.  
* **[21:15]** Prompting Shortcuts in natural language to build an automated action pulling YouTube video view counts.

**Claims & numbers**  
* The presenter claims AFM 3 Core is a 3-billion-parameter dense on-device model running on iPhone 15 Pro and later.  
* The presenter claims AFM 3 Core Advanced is a 20-billion-parameter sparse MoE model (1 to 4 billion active parameters) on A19 Pro and later devices, loaded dynamically from NAND flash storage into RAM.  
* The presenter states an iPhone 17 Pro has 12 GB of RAM.  
* The presenter states Apple Cloud Pro runs on Nvidia GPUs inside Google data centers via Private Cloud Compute.  
* The presenter claims the extracted system prompt instructions total approximately 102,000 characters across 21 sections (including 23,000 characters on platform behavior, 19,000 on citations, 9,500 on guardrails, and 350 characters for Siri's personality description).  
* The presenter claims that across 247 logged requests in his Apple Intelligence Report, every single one showed offloading to Private Cloud Compute rather than executing strictly on-device.

**Notable quotes**  
* **[03:49]** "The idea is that Apple can choose a set based on your prompt and largely stick with it as there are only occasional opportunities to swap..."  
* **[15:39]** "Perception is all local, but almost all cognition is in the cloud right now."  
* **[20:31]** "Short commands in succession beat one long command almost every time."

**Assessment**  
This is a hands-on tech review and technical breakdown, not an official launch video. The author demonstrates both live successes and failures on real hardware while inspecting actual iOS diagnostic logs and system prompts.
