Just last October, Andrej Karpathy dismissed AI agents: “They just don’t work.” Now he says 80 percent of his coding is agent-based and calls it the “biggest change to my basic coding workflow in ~2 decades.” A typically measured voice is joining the agent coding hype, but with some warnings attached.
OpenAI is charging around $60 per 1,000 impressions for its initial ChatGPT ads, far above typical online advertising rates in the low single digits and closer to what advertisers pay for premium TV spots like NFL games, according to The Information. The ads show up below ChatGPT responses in the free and lower-cost "Go" tiers.
OpenAI is also reportedly charging per impression rather than per click. Advertisers typically prefer click-based billing because it's easier to measure results. The decision to go with impressions likely reflects how AI chatbot users behave differently than traditional search users: they click on external links far less often. Perplexity uses the same approach, also charging per 1,000 impressions.
The move toward advertising—at premium prices and in a format that's less appealing to advertisers—suggests OpenAI needs to ramp up revenue quickly to justify its high valuation to investors. Sam Altman previously called ChatGPT advertising a last resort and a potential dystopia.
Microsoft has unveiled its new AI inference chip, Maia 200. Built specifically for inference workloads, the chip delivers 30 percent better performance per dollar than current-generation chips in Microsoft's data centers, the company claims. It's manufactured using TSMC's 3-nanometer process, packs over 140 billion transistors, and features 216 GB of high-speed memory.
According to Microsoft, the Maia 200 is now the most powerful in-house chip among major cloud providers. The company claims it delivers three times the FP4 performance of Amazon's Trainium 3 while also outperforming Google's TPU v7 in FP8 calculations—though independent benchmarks have yet to verify these figures.
Microsoft says the chip already powers OpenAI's GPT 5.2 models and Microsoft 365 Copilot. Developers interested in trying it out can sign up for a preview of the Maia SDK. The Maia 200 is currently available in Microsoft's Iowa data center, with Arizona coming next. More technical details about the chip are available here.
Nvidia invests $2 billion in cloud provider Coreweave, buying shares at $87.20 each. The two companies are expanding their existing partnership to build AI data centers with more than 5 gigawatts of capacity by 2030.
As part of the deal, Coreweave will deploy multiple generations of Nvidia hardware, including the Rubin platform, Vera processors, and Bluefield storage systems. The partners also plan to integrate Coreweave's software into Nvidia's reference architectures for cloud providers and enterprise customers.
Coreweave went public in March 2025 and specializes in AI-optimized cloud services. The company is involved in expanding OpenAI's Stargate project. OpenAI has also invested several billion dollars in Coreweave.
Internal crisis meetings, a leader who cried “bullshit” and convinced no one, and billion-dollar negotiations that fell apart: Bloomberg reveals the backstory behind Apple’s decision to partner with Google.
The story sounds simple: ChatGPT launched, jobs in AI-exposed fields disappeared. But a new study shows the decline started months before the chatbot arrived. The researchers argue we shouldn’t pin all labor market problems on AI.
