Anthropic's Sonnet 5.5 nears Opus at half the price
Image source: AnthropicThe Rundown: Anthropic just rolled out Claude Sonnet 5.5, a 30% faster mid-tier model joining Opus in its new 5.5 family, with big gains over the last Sonnet in knowledge work and coding, and even rivaling Opus on certain tests at half the price.The details: - 5.5 keeps its predecessor’s pricing, with Anthropic saying jobs cost up to 30% less and top Sonnet 5's best on low/medium effort for around 1/10 the cost.
- Sonnet also comes in at a 56 on AA’s Intelligence Index, behind only 5.5 Opus and surpassing Fable 5.1 and GPT-6 Astra’s 53.
- It nearly ties Opus 5.5 on AA's several office-work tests, while coding jumps put it near or ahead of both Opus and Astra on several development benchmarks.
- The model’s cyber skills also earned the first Sonnet-tier guardrails, with the same security fallbacks seen previously in Opus and Fable restrictions.
More data will not fix a bad AI decision
The Rundown: Data has fueled the first wave of AI. The next will be shaped by how well organizations translate their knowledge, expertise, and operational logic into forms AI can use. In this whitepaper, we explore how businesses can bridge the gap between information and decision-making.What you'll learn:- The limits of a data-centric approach to AI
- Why operational knowledge is becoming a strategic AI asset
- Practical ways to make expertise AI-ready
AI leaders continue to sound the self-improving AI alarm
Image source: University of CambridgeThe Rundown: Anthropic’s Jack Clark, OpenAI’s Jakub Pachocki, AI pioneers Geoffrey Hinton and Yoshua Bengio, and other leading AI voices co-authored a paper urging preparation for an “intelligence explosion,” where models building better versions of themselves create years of advances in months.The details:- Anthropic's own tracking shows AI now completes 26% of the lab's R&D work on its own, with humans just steering from above, up from just 1% in March.
- The paper's math shows how fast things could scale, with one post-automation scenario cutting a year of today's AI progress to just five weeks.
- Proposed fixes include caps on how fast capabilities can climb, options to pause specific jobs inside data centers, and outside auditors embedded in labs.
- At the extreme end of the range of outcomes, according to the paper: “the marginalization or extinction of humanity.”
Pick the right Claude model with one quick test
The Rundown: In this guide, you will learn how to choose between Claude Opus 5.5, Opus 5, and Fable 5.1. We'll give all three the same launch-email brief, then check which one catches the errors and which needs the most fixing.Step-by-step:- Open a new Claude chat, click the model name beside the send button, and pick Opus 5.5 at its default effort
- Paste the fictional Worknote brief from the full guide. It hides two errors to catch: an old launch date and an unproven “save five hours every week” claim. Add: “Use only the supplied brief. List the errors in version 1, then write a launch email”
- Run the same brief and prompt on Fable 5.1 and Opus 5, in another chat. Keep settings identical and give each model one attempt
- Score each email on the right date, price, and trial terms, plus whether it caught both errors. Note how long each fix takes, then rerun any failure at higher effort
What are CIOs prioritizing in 2027?
The Rundown: Only 48% of digital initiatives hit targets. But why? Uncover findings from 2,500+ chief information officers (CIOs) on where to invest, how AI strategies are shifting, and what separates leading CIOs from the rest.In this webinar, you’ll learn how to:- Benchmark against leading organizations

- Navigate new AI strategies
AMD strikes $8.2B deal for Fei-Fei Li's World Labs
Image source: World LabsThe Rundown: Advanced Micro Devices (AMD) just agreed to acquire World Labs, the startup from “godmother of AI” Fei-Fei Li that builds models to generate 3D worlds, in an $8.2B all-stock deal — with the AI pioneer joining as the chip giant’s new chief scientist. The details: - Li wrote that AMD CEO Lisa Su backed the lab early on, and the teams have been tuning how World Labs' models train and run on AMD GPUs since last year.
- Both AMD and Nvidia invested in World Labs' $1B round in February, with the deal now giving AMD a lab that its rival (and the CEO’s cousin) was also funding.
- Li will report directly to Su, saying that her team needs to get “closer to the hardware” since AI without that focus stays “hobbled in efficiency.”
- World's first product, Marble, launched last November and turns text, photos, or video into editable 3D spaces, with a newer Atlas currently in early access testing.
