Apple's iOS 27.3 update rolls out on Tuesday, and Siri AI's cross-app actions arrive as part of a Developer Preview for testing before general release.

The new "app skills" feature lets third-party developers combine multiple tasks into a single Siri action, a step beyond the smaller feature set Apple opened previously.

Users won't need to mention an app's name while it's in the foreground, during a Live Activity, or in an ongoing conversation with Siri AI.

Apple's own apps, including Calendar, Files, Finder, Journal, Mail, Maps, Messages, Music, Notes, Photos, Preview, Reminders, Safari, Shortcuts, and Weather, all get expanded Siri AI capabilities.

Ride share users can request a ride by voice, follow Live Activity updates while they wait, and change pickup with "Hey Siri, change my ride pickup to a new address."

Self-hosting GLM 5.1 cost about a tenth of using OpenAI's Codex or Anthropic's Claude Code, according to Revolut's internal comparison of its inference bills.

The model has roughly 754 billion total parameters, with 40 billion activated per token, and needs about 380 GB of GPU memory just for weights.

Revolut serves GLM-5.3 on 56 Nvidia B200 GPUs, hitting sub-3-second time to first token on context windows around 256,000 tokens.

The biggest gains came from NVFP4 quantization, disaggregated prefill and decode, and tuned hyperparameters and context lengths, with GPU count mattering less.

Engineers get roughly 200 tokens per second during the workday and about 800 tokens per second after 5 pm, with flat billing and no end-of-month bill shock.

The same C++ SAM 2 code ran on GPUs in a macOS laptop, an iOS phone, and an Android phone without per-platform rewrites.

On a MacBook Pro, the graph ran about 1.5x faster than Apple MLX using fp16 for the image encoder plus mask decoder.

A coding agent rewrote operations that triggered CPU fallback on WebGPU, swapping in GPU-compatible arithmetic to keep work on the GPU.

The API supports direct weight ingestion, so you can load weights straight from checkpoints without an intermediate conversion step.

Planned updates include direct ML Drift backend support, more NPU-friendly operations, automatic full-graph quantization, and expanded dynamic shapes for image sizes, batches, and sequence lengths.

OpenAI counts any user query that triggers a web search as a search, which is how ChatGPT reached a volume equal to 20 percent of Google's.

Microsoft's CEO said Bing held about 3 percent of the search market after more than a decade of effort, a useful baseline for how hard this gap is.

OpenAI's consumer product lead announced the sponsored product imagery change at a press event on Monday, replacing plain logo-and-link placements.

OpenAI likely routes a significant share of ChatGPT searches through Microsoft Bing plus its in-house search index, with some speculation about Google results too.

OpenAI sees ads as its path to profitability ahead of an IPO potentially slated for early next year, and says earlier ads produced no lasting backlash.

The complaint alleges Brave's browser has a default setting that bypasses website paywalls, and that it shows its own ads in place of the publisher's ads on pages.

The plaintiffs claim Brave has earned more than $100 million by copying and reselling publishers' work without consent or permission, according to the filing in federal court.

AI companies pay Brave for real-time web content from its search index. The suit says the Brave Search API is used by some of the biggest names in AI.

The lawsuit cites the Digital Millennium Copyright Act, alleging Brave circumvented technological measures that protect paywalled articles from unauthorized access and copying.

Relief sought includes a permanent injunction, statutory and actual damages, and restitution and disgorgement of all revenue and profits. The case sits in the Southern District of New York.

Google will make Gemini, Gemini Notebook, Gemini in Classroom, and Google Search opt-out by default for K-12 schools when the changes roll out in the coming months.

Admins must manually enable AI tools. There is no per-tool toggle, so schools choose between allowing all Google AI features or none of them at once.

Blocked students lose access to Google Search entirely and see a school-facing message explaining why, which means the AI decision directly affects everyday research workflows.

Google's Guided Learning mode offers one-on-one tutoring without giving full answers, and it sits alongside the standard Gemini-based AI version inside Search.

Schools unhappy with the approach can switch to DuckDuckGo, which lets you disable AI features, though Google's Chromebook footprint makes that a harder sell in practice.
