Does a chatbot have a soul? Sort of.

"We believe this is the first documented case of a large-scale cyberattack executed without substantial human intervention," Anthropic said earlier this month.

Anthropic today released Opus 4.5, its flagship frontier model, and it brings improvements in coding performance, as well as some user experience improvements that make it more generally competitive with OpenAI’s latest frontier models.

Perhaps the most prominent change for most users is that in the consumer app experiences (web, mobile, and desktop), Claude will be less prone to abruptly hard-stopping conversations because they have run too long. The improvement to memory within a single conversation applies not just to Opus 4.5, but to any current Claude models in the apps.

Users who experienced abrupt endings (despite having room left in their session and weekly usage budgets) were hitting a hard context window (200,000 tokens). Whereas some large language model implementations simply start trimming earlier messages from the context when a conversation runs past the maximum in the window, Claude simply ended the conversation rather than allow the user to experience an increasingly incoherent conversation where the model would start forgetting things based on how old they are.

An outage at internet infrastructure giant Cloudflare took down several big websites and services, including ChatGPT, Claude, Spotify, and X.

The frenzy of AI deals and cloud partnerships reached another zenith Tuesday morning as Microsoft, Nvidia, and Anthropic announced a surprise alliance that includes a $5 billion investment by Microsoft in Anthropic — which, in turn, committed to spend at least $30 billion on Microsoft’s Azure cloud platform.

Nvidia, meanwhile, committed to invest up to $10 billion in Anthropic to ensure the Claude maker’s frontier models are optimized for its next-generation Grace Blackwell and Vera Rubin chips.

The deal reflects growing moves by major AI players to collaborate across the industry in an effort to build and expand capacity and access to next-generation AI models. Microsoft recently renegotiated its partnership with OpenAI and has been increasingly partnering with others in the industry.

Anthropic has been closely tied to Amazon, which has committed to invest a total of $8 billion in the startup. Anthropic says in a post that Amazon remains its “primary cloud provider and training partner” for AI models. We’ve contacted Amazon for comment on the news.

OpenAI, for its part, recently announced a seven-year, $38 billion agreement with Amazon to expand its AI footprint to the Seattle tech giant’s cloud infrastructure.

Beyond the massive capital flows, the Microsoft-Nvidia-Anthropic partnership expands where enterprise customers can access Anthropic’s technology. According to the announcement, Microsoft customers will be able to use its Foundry platform to access Anthropic’s next-generation frontier models, identified as Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5.

Microsoft also committed to continuing access for Claude across its Copilot family, ensuring the models remain available within GitHub Copilot, Microsoft 365 Copilot, and Copilot Studio.

Anthropic, the developer behind Claude AI, says a Chinese state sponsored group used its model to automate most of a cyber espionage operation against about 30 companies with Claude handling up to 90% of the technical work.

Researchers from Anthropic said they recently observed the “first reported AI-orchestrated cyber espionage campaign” after detecting China-state hackers using the company’s Claude AI tool in a campaign aimed at dozens of targets. Outside researchers are much more measured in describing the significance of the discovery.

Anthropic published the reports on Thursday here and here. In September, the reports said, Anthropic discovered a “highly sophisticated espionage campaign,” carried out by a Chinese state-sponsored group, that used Claude Code to automate up to 90 percent of the work. Human intervention was required “only sporadically (perhaps 4-6 critical decision points per hacking campaign).” Anthropic said the hackers had employed AI agentic capabilities to an “unprecedented” extent.

“This campaign has substantial implications for cybersecurity in the age of AI ‘agents’—systems that can be run autonomously for long periods of time and that complete complex tasks largely independent of human intervention,” Anthropic said. “Agents are valuable for everyday work and productivity—but in the wrong hands, they can substantially increase the viability of large-scale cyberattacks.”

ChatGPT maker OpenAI, exercising newfound freedom under its renegotiated Microsoft partnership, will expand its cloud footprint for training and running AI models to Amazon’s infrastructure under a new seven-year, $38 billion agreement.

The deal, announced Monday, positions Amazon as a major infrastructure provider for Microsoft’s flagship AI partner, highlighting seemingly insatiable demand for computing power and increasingly complex alliances among big companies seeking to capitalize on AI.

It comes as Microsoft, Amazon, and big tech companies attempt to reassure investors who’ve grown concerned about a possible bubble in AI spending and infrastructure investment.

Under its new Amazon deal, OpenAI is slated to begin running AI workloads on Amazon Web Services’ new EC2 UltraServers, which use hundreds of thousands of Nvidia GPUs. Amazon says the infrastructure will help to run ChatGPT and train future OpenAI models.

Amazon shares rose nearly 5% in early trading after the announcement.

“Scaling frontier AI requires massive, reliable compute,” said OpenAI CEO Sam Altman in the press release announcing the deal. “Our partnership with AWS strengthens the broad compute ecosystem that will power this next era and bring advanced AI to everyone.”

Matt Garman, the AWS CEO, said in the release that Amazon’s cloud infrastructure will serve as “a backbone” for OpenAI’s ambitions.

In an interview with CNBC, Dave Brown, Amazon’s vice president of compute and machine learning services, said the new agreement represents “completely separate capacity” that AWS is building out for OpenAI. “Some of that capacity is already available, and OpenAI is making use of that,” Brown told CNBC.

Amazon has also been deepening its investment in AI infrastructure for Anthropic, the rival startup behind the Claude chatbot. Amazon has invested and committed a total of $8 billion in Anthropic and recently opened Project Rainier, an $11 billion data center complex for Anthropic’s workloads, running on hundreds of thousands of its custom Trainium 2 chips.

Microsoft has been expanding its own relationship with Anthropic, adding the startup’s Claude models to Microsoft 365 Copilot, GitHub Copilot, and its Azure AI Foundry platform

Up to this point, OpenAI has relied almost exclusively on Microsoft Azure for the computing infrastructure behind its large language models. The new deal announced by Microsoft and OpenAI last week revised that relationship, giving OpenAI more flexibility to use other cloud providers — removing Microsoft’s right of first refusal on new OpenAI workloads.

At the same time, OpenAI committed to purchase an additional $250 billion in Microsoft services. Microsoft still holds specific IP rights to OpenAI’s models and products through 2032, including the exclusive ability among major cloud platforms to offer OpenAI’s technology through its Azure OpenAI Service.

OpenAI’s new $38 billion deal with Amazon builds on a relationship that began earlier this year, when Amazon added OpenAI’s first open-weight models in five years to its Bedrock and SageMaker services. Released under an open-source license, those models weren’t bound by OpenAI’s exclusive API agreement with Microsoft, letting Amazon offer them on its platforms.

The latest announcement is part of a series of deals by OpenAI in recent months with companies including Oracle and Google — committing hundreds of billions of dollars overall for AI computing capacity, and raising questions about the long-term economics of the AI boom.

Amazon’s third-quarter profits rose 38% to $21.2 billion, but a big part of the jump had nothing to do with its core businesses of selling goods or cloud services.

The company reported a $9.5 billion pre-tax gain from its investment in the AI startup Anthropic, which was included in Amazon’s non-operating income for the quarter.

The windfall wasn’t the result of a sale or cash transaction, but rather accounting rules. After Anthropic raised new funding in September at a $183 billion valuation, Amazon was required to revalue its equity stake to reflect the higher market price, a process known as a “mark-to-market” adjustment.

To put the $9.5 billion paper gain in perspective, the Amazon Web Services cloud business — historically Amazon’s primary profit engine — generated $11.4 billion in quarterly operating profits.

At the same time, Amazon is spending big on its AI infrastructure buildout for Anthropic and others. The company just opened an $11 billion AI data center complex, dubbed Project Rainier, where Anthropic’s Claude models run on hundreds of thousands of Amazon’s Trainium 2 chips.

Amazon is going head-to-head against Microsoft, which just re-upped its partnership with ChatGPT maker OpenAI; and Google, which reported record cloud revenue for its recent quarter, driven by AI. The AI infrastructure race is fueling a big surge in capital spending for all three cloud giants.

Amazon spent $35.1 billion on property and equipment in the third quarter, up 55% from a year earlier.

Andy Jassy, the Amazon CEO, sought to reassure Wall Street that the big outlay will be worth it.

“You’re going to see us continue to be very aggressive investing in capacity, because we see the demand,” Jassy said on the company’s conference call. “As fast as we’re adding capacity right now, we’re monetizing it. It’s still quite early, and represents an unusual opportunity for customers and AWS.”

The cash for new data centers doesn’t hit the bottom line immediately, but it comes into play as depreciation and amortization costs are recorded on the income statement over time.

And in that way, the spending is starting to impact on AWS results: sales rose 20% to $33 billion in the quarter, yet operating income increased only 9.6% to $11.4 billion. The gap indicates that Amazon’s heavy AI investments are compressing profit margins in the near term, even as the company bets on the infrastructure build-out to expand its business significantly over time.

Those investments are also weighing on cash generation: Amazon’s free cash flow dropped 69% over the past year to $14.8 billion, reflecting the massive outlays for data centers and infrastructure.

Amazon has invested and committed a total of $8 billion in Anthropic, initially structured as convertible notes. A portion of that investment converted to equity with Anthropic’s prior funding round in March.
