DeepSeek has released its latest AI models, the V4 Pro and Flash versions, a bit over a year after it went viral and became the top rated free app on Apple's App Store in the US. “Welcome to the era of cost-effective 1 million context length,” DeepSeek said in its announcement . Context length is what you call the maximum number of tokens that an AI model can remember, so the bigger it is, the more coherent and consistent an AI is when it comes to extended conversations. OpenAI’s recently announced GPT‑5.5 has a context window ranging from 400,000 to 1 million, for instance. The new model is still open-source, allowing users to download its code and modify it if they want. DeepSeek says V4 Pro has enhanced agentic capabilities and claims that it rivals top closed-source models when it comes to reasoning. It also says that it trails only Gemini-3.1-Pro in rich world knowledge. Meanwhile, V4 Flash isn’t quite as powerful as the V4 Pro, but it has faster response times. Still, its reasoning abilities closely approach V4 Pro, DeepSeek says, and it performs on par with with the Pro version on simple Agent tasks. Shortly after DeepSeek topped the App Store charts, it was banned for use by US federal agencies and on government-owned devices. Authorities believed it was a national security risk and posed a threat to US AI stocks. South Korea also paused downloads of its app over privacy concerns. 🚀 DeepSeek-V4 Preview is officially live & open-sourced!

Microsoft is planning to get rid of more US employees via its first voluntary buyout program, CNBC reports . The buyout program will reportedly be offered to US employees at "the senior director level and below whose years of employment and age add up to 70 or higher," and could cover up to 7 percent of the company's US workforce. With around 125,000 employees in the US as of June 2025 , that could mean up to 8,750 will be offered a paid exit when Microsoft begins its program in May. That's a smaller figure than the 15,000 or so employees the company laid off in May and July of 2025, but still significant, particularly if the majority of employees do take the buyout. "Our hope is that this program gives those eligible the choice to take that next step on their own terms, with generous company support," Microsoft's executive vice president and chief people officer Amy Coleman shared in a memo viewed by CNBC . Engadget has contacted Microsoft to confirm the existence of the voluntary buyout program and other details CNBC reported. We'll update this article if we hear back. Microsoft used its 2025 layoffs to streamline layers of management and its video game business, but these new cuts may have a lot more to do with AI. Not necessarily because the company's adoption of AI tools has made employees redundant, but rather because Microsoft continues to aggressively spend on AI infrastructure. The company said it spent $37.5 billion in capital expenditures during Q2 2026, much of which went toward data center buildout.
