Humanity has entered the singularity, says Altman

Welcome back, Superhuman. The wait is (apparently) over. Humanity has entered the singularity, according to a weekend interview from Sam Altman. The OpenAI CEO described “the singularity” as an era of rapid advancement, not an event. And he might have a point — we just got yet another cutting-edge model on Friday.

Today: ChatGPT Work can access your most-used websites, how to clean and prepare messy data with ChatGPT, and get the latest prompts and trending social posts.

1. Anthropic launches Claude Opus 5, a cheaper near-frontier model: Claude Opus 5 matches Fable 5’s performance on many benchmarks, at roughly half the price. The model is now live across all Anthropic platforms, and the AI leader says it excels at agentic coding and enterprise work. It’s also available in fast mode, which runs at 2.5x its normal speed. Anthropic published an Opus 5 Prompting Guide to help you get the most value out of the model.

2. Microsoft launches cheaper in-house models: The tech giant released public previews for MAI-Image-2.5-Pro and MAI-Voice-2-Flash, two new models joining a family that powers Bing, PowerPoint, OneDrive, Dynamics 365, and Azure. The launch is part of Microsoft’s broader push to reduce its reliance on OpenAI after amending its partnership in April to reduce exclusivity between the two firms. Explore the new models.

3. ChatGPT Work can now access your logged-in websites: You can now sign OpenAI's newest productivity agent into your most-used websites so it can get work done for you. The agent stays logged in across sessions, so you only have to sign it in once. Sam Altman touted ChatGPT Work’s capabilities in a weekend post, saying the agent built a custom website for him and his friends to plan and coordinate a trip.

Friday’s most-clicked story: Black Forest Labs launched FLUX 3, a new model that can generate images and video+audio jointly. The lab calls its outputs “truer to life” across every style.

Stale data can ruin even the smartest model. Your agent deserves data you (and your customers) can trust.

Coresignal is the data layer that keeps agents grounded in reality.

Rallying behind open-weight AI. It’s not often that someone’s first social media post gets 60M views. But that’s what happened to Nvidia CEO Jensen Huang on Friday. The post was a public letter explaining why open models matter. The statement joins hundreds of others speaking out against a potential ban on open weight Chinese models.

The argument against open weight. The primary reason to ban open weight models is safety. In recent months, open weight models — which anyone can download, run, and modify — have started to match the performance of top frontier ones. Once an open model is released, anyone can use it however they choose with essentially no guardrails. But many tech leaders think this risk is worth the reward.

The argument supporting open weight. At least 25 tech firms have publicly voiced support for open weight models, including Nvidia, Microsoft, IBM, and Dell. Their reasoning is that open weight AI creates competition that drives down costs and distributes AI’s benefits broadly across the economy. Without open weight models, AI could become concentrated among just a handful of frontier labs.

Defining the decade ahead. The final decision will play a major role in how AI and society develop over the coming years. It will also heavily influence the initial public offerings of Anthropic and OpenAI, both of which are planning to list as soon as this year. Notably, Anthropic is the only major AI lab that has not endorsed the letter.
