1. Apple Researchers Train Small Networks to Route RAG Queries, Reaching 99% Recall About 8x Faster on a FAISS Index
Apple published a research highlight on amortized maximum inner product search (MIPS), from its ICML 2026 paper “Amortizing Maximum Inner Product Search with Learned Support Functions,” which trains small neural networks once, offline, for a fixed database of keys so that retrieval is tuned to the distribution of queries a production system actually sees, such as short user questions against long curated passages in RAG. The approach rests on the observation that the function mapping a query to its best inner product with any key is the set’s support function, which is convex and whose gradient is the best-matching key. SupportNet, a loosely constrained input convex neural network, learns one support function per cluster and replaces centroid routing in inverted file (IVF) indexes; KeyNet directly predicts the best-matching key, kept consistent with the support function by a loss derived from Euler’s theorem for homogeneous functions, and acts as a query rewriter in front of an unmodified IVF index. Both are trained by regression on sampled queries paired with exhaustive-search ground truth, in sizes from 1% to 20% of the database size with 16 layers. On Natural Questions (about 2.6 million passages in 128 clusters), a small SupportNet reached 95% routing recall in 1.74 ms versus 3.36 ms for centroid routing, and while scanning 5% of the database the learned routers found the right partition 90% to 93% of the time versus 87.5%. With a FAISS IVF index, the largest KeyNet reached 99% recall in 0.23 ms versus 1.8 ms for the raw query, and needed up to 11x fewer scanned keys for that recall (0.009% versus 0.10% of the database). Apple recommends KeyNet when inference speed is the bottleneck and SupportNet when a calibrated score is needed or compute is tight, and says both are reasonably robust to mild query distribution shift.

2. Apple Creator Studio Update With Assistants Built on Apple Models and OpenAI Starts Rolling Out
Apple began rolling out on November 5 the Apple Creator Studio update it announced on October 27, 9to5Mac reports, after originally giving only a November window. Per Apple’s announcement as quoted by 9to5Mac, the new intelligent assistants are built on a combination of Apple-built models and OpenAI: in Logic Pro for Mac (beta) the assistant can start a song, set up a vocal track from a single prompt or refine an active project, and in Keynote, Pages and Numbers (beta) it understands document context to design and animate slides, draft and restructure text, and calculate, visualize and organize data, including recommending chart types with a one-tap preview and building tables using world knowledge. The update also brings Model Context Protocol support that lets external AI agents and tools read content, perform edits and run automated actions in Keynote, Pages and Numbers, Generate Fill in Pixelmator Pro, and MotionVFX effects and Content Hub stock video in Final Cut Pro. Apple’s October announcement said the assistants require an Apple Intelligence-capable device and U.S. English, and that the update is free for existing subscribers ($12.99 a month or $129 a year for new ones).

3. First iOS 27.3 and macOS 27.3 Public Betas Bring New Siri AI App Actions and the Apple Intelligence Health App to Public Testers
Apple released the first public betas of iOS 27.3, iPadOS 27.3 and macOS 27.3 on November 5, two days after the developer betas, putting the redesigned, Apple Intelligence-based Health app and expanded Siri AI capabilities in front of public testers. On iPhone, new Siri AI actions in Apple’s apps let users ask Siri to make and save a playlist, schedule an iMessage to send later or create a Journal entry, and the Health app’s Insights tab gathers sleep, activity and other trends on iPhones that support Apple Intelligence. On the Mac, 9to5Mac lists more complex Siri AI actions in Messages, Music, Calendar, Photos and Reminders, file and folder management and Safari tab organization through Siri AI. Testers enroll through the free Apple Beta Software Program at beta.apple.com. Source Source
4. iOS 27.3 Beta Code Points to Third-Party AI Chatbots Such as ChatGPT and Claude on HomeView
Apple appears to be preparing support for third-party AI chatbot apps on its HomeView home hub, based on code in the iOS 27.3 beta, 9to5Mac reported on November 5, citing the leaker pdfu. Earlier in the month pdfu spotted an unused ConversationalApps flag; in the 27.3 beta, PebblePlay, which pdfu describes as HomeView’s CarPlay bridge, gains a Conversational Apps category along with bidirectional audio routing, session management and groundwork for interruptions, though pdfu says the feature is “still not fully wired up.” Apple uses such category flags to decide which kinds of third-party apps may run on the device, as it does with CarPlay. Apple has not announced the feature or a timeline. Source
