The CEO sent the memo to Nvidia colleagues on a Sunday, acknowledging the affair and apologizing to his wife for being unfaithful to her.

Nvidia's Board of Directors started an independent investigation into national security concerns, prompted by news reports that surfaced about the relationship.

The CEO said he takes full responsibility, accepts criticism, and hopes his family can heal while he works to earn back trust from colleagues and partners.

Nvidia plans to sell 27,500 next-generation Rubin chips to Japan, which intends to use them to build a homegrown foundational AI model for robots.

The memo said the CEO has fallen short of his responsibility to serve Nvidia and reaffirmed his commitment to protecting the company and supporting America's national security.

OpenAI originally sought $30 billion or more at a $1.4 trillion valuation, and two investors pushed the ask as high as $1.5 trillion before the market turned.

SoftBank and Abu Dhabi's MGX took part in the round, which is priced at $1.25 trillion pre-money according to the company's CFO in a TV interview.

OpenAI's business grew 70% quarter over quarter in the third quarter, and its enterprise business doubled, with revenue splitting about 50/50 between consumer and enterprise.

OpenAI has 1.2 billion weekly ChatGPT users and an ads run rate of $1 billion by August, giving it a consumer base most rivals can't touch.

The round could reach $20 billion total, and a separate report put a follow-on of up to $9 billion on top, though that second portion has not yet closed.

Entire's trails display eval scores updated on every push, with the last five runs and the current run visible for each evaluation.

A review agent in a cloud sandbox scores each push on code quality, security, slop, and whether human review is required.

Entire claims pushes run up to 89 times faster than GitHub, thanks to a fully distributed architecture underneath the forge.

Nothing merges until every review finding is either resolved or closed, and repo-level Gates can define the approval conditions.

Continuous memory runs on two open-source tools, entire-graph and entire-brain, so agents reuse repository knowledge across sessions instead of starting cold.

Anthropic says its models improve roughly twice as quickly as they did a year ago, and the speedup is not explained by scaling compute alone.

Employees using the company's most capable internal model reported being 12 times as productive as they would be without AI assistance.

Three of Anthropic's newest models are still unreleased, having finished training in July, August-September, and September-October respectively.

METR received confidential research, model performance data, and employee interviews, but Anthropic redacted its final report extensively before publication.

Anthropic justified the redactions by arguing that releasing the information could benefit rivals, and it plans its own report on AI progress.

The core store, graph.db, is a triple store using 181 entity classes and 278 predicates to describe people, organizations, events, and software.

Each edge in the graph stores a confidence value, its sources, source duplicates, and a timestamp, so you can trace where any inference came from.

The graph ingests Family Sharing data including the age of every family member, plus Health's Medical ID emergency contact details on the device.

Device signals feeding the graph include screen locked state, Wi-Fi, Bluetooth, charging status, and ambient light readings sampled over time.

Photos co-appearance tables record who shows up with whom, while a separate communication log and location and movement tables track your routine.

Hackers obtained names, usernames, password hashes, and live tokens for every Chainalysis user, a scope that covers the entire customer base rather than a subset.

Chainalysis discovered the exposure two days before disclosing it on Wednesday, a delay that leaves customers with less time to rotate secrets before attackers act.

An on-path attack exposed some customer passwords. Chainalysis says the attack vector has been identified and fixed, but the origin of the attack remains unknown.

Reactor and Data Solutions access has been removed, while KYT and Address Screening are returning in phases. Customers must reset credentials once they regain access.

Chainalysis has not found evidence that investigation data was accessed or that attribution data was manipulated, according to the company's statement on the incident this week.
