xAI is testing Grok 4.20 to take on GPT-5, may launch this month

bleepingcomputer.com Unknown 2025-12-01 03:34:44

Elon Musk-owned xAI is testing Grok 4.20, a new model update to Grok 4, which already competes with GPT-5 in some benchmarks, such as ARC-AGI 2. GPT-5 is one of the best models for coding, and it competes with Claude Opus 4.1 head-to-head in some coding challenges. On the other hand, Grok falls a bit short when it comes to building full-fledged apps. But that might change soon as xAI is testing Grok 4.20. In a post on X, Elon Musk teased Grok 4.20 for a late August launch. Previously, Elon

Apple brings OpenAI's GPT-5 to iOS and macOS

OpenAI's GPT-5 model went live for most ChatGPT users this week, but lots of people use ChatGPT not through OpenAI's interface but through other platforms or tools. One of the largest deployments is iOS, the iPhone operating system, which allows users to make certain queries via GPT-4o. It turns out those users won't have to wait long for the latest model: Apple will switch to GPT-5 in iOS 26, iPadOS 26, and macOS Tahoe 26, according to 9to5Mac.

An AI Model for the Brain Is Coming to the ICU

wired.com Emily Mullin 2025-12-01 03:00:00

The Cleveland Clinic is partnering with San Francisco–based startup Piramidal to develop a large-scale AI model that will be used to monitor patients’ brain health in intensive care units. Instead of being trained on text, the system is based on electroencephalogram (EEG) data, which is collected via electrodes placed on the scalp and then read out by a computer in a series of wavy lines. EEG records the brain’s electrical activity, and changes in this activity can indicate a problem. In an ICU

The great EV buying frenzy has officially begun.

How attention sinks keep language models stable

We discovered why language models catastrophically fail on long conversations: when old tokens are removed to save memory, models produce complete gibberish. We found models dump massive attention onto the first few tokens as "attention sinks"—places to park unused attention since softmax requires weights to sum to 1. Our solution, StreamingLLM, simply keeps these first 4 tokens permanently while sliding the window for everything else, enabling stable processing of 4 million+ tokens instead of j
