Description
Hacker Newsroom AI for 28 April recaps 5 major AI Hacker News stories, moving through microsoft openai reset, mercor voice breach, meta manus blocked, dirac tops terminalbench.
1. Microsoft OpenAI Reset
The next story is Bloomberg’s report that Microsoft and OpenAI have ended their exclusive, revenue-sharing deal, with Microsoft no longer taking a cut of OpenAI’s revenue and the partnership opening to other clouds. That matters because it reshapes one of AI’s most important business arrangements.
2. Mercor Voice Breach
The next story is about 4 terabytes of voice samples reportedly stolen from 40,000 AI contractors at Mercor, and the article argues that pairing clean voice recordings with ID scans creates a deepfake-ready breach that raises the stakes for fraud, impersonation, and biometric security. Hacker News reaction was alarmed but split, with many saying voice verification was always a bad tradeoff, while others questioned the realism of the proposed defenses and whether the writeup overstates the timeline or the company’s public response.
3. Meta Manus Blocked
The next story is about China blocking Meta’s $2 billion takeover of the AI startup Manus. The article says Beijing ordered the deal unwound under investment and export-control rules, and it matters because it shows how tightly AI talent and offshore dealmaking are now being policed.
4. Dirac Tops TerminalBench
The next story is about Dirac, an open-source coding agent that the author says topped TerminalBench 2.0 with Gemini-3-flash-preview while cutting API costs and improving code quality, which matters because it argues that tighter context management can make agents both cheaper and better. Hacker News was split between excitement over the AST-driven editing and batch operations, and skepticism about whether the win came from the harness, the model, or benchmark-specific tricks.
5. Prompt API
The next story is about Chrome’s Prompt API, which brings Gemini Nano into the browser so sites and extensions can ask for summaries, search, filtering, and other AI tasks locally. The article argues that this could make on-device AI practical for everyday web features.
That's it for today, I hope this is going to help you build some cool things.
