DeepSeek has released DeepSeek-Math-V2, an open-source math model that reaches gold-medal performance on IMO 2025 tasks. It scored 118 out of 120 on the 2024 Putnam exam and solved 5 of 6 IMO problems, beating top human results. On IMO ProofBench it reached 61.9 percent, close to Google’s Gemini Deep Think and far above GPT-5. The model uses a generator-verifier setup where one model writes a proof and another checks each step, helping it fix weak logic. By open-sourcing it, DeepSeek is giving the community access to high-level mathematical reasoning usually kept behind closed labs.

AI companies are moving into online shopping as they search for steadier revenue. OpenAI recently added a “shopping research” feature in ChatGPT that helps users find products by asking simple questions like finding a vacuum or choosing a gift. Perplexity launched a free shopping tool with PayPal that lets people buy from more than 5,000 merchants and even try items on with virtual avatars. Google has also started showing ads inside AI Mode. These tools help AI firms make money and collect valuable intent data that improves personalization and keeps users engaged.

OpenAI is updating ChatGPT so you can use voice right inside a normal chat instead of switching to a separate screen. You can now talk to ChatGPT while watching its replies appear on the page, including any images or maps it shows. Earlier, voice mode hid everything behind a full-screen interface, which made it hard to review messages or see missed responses. The new setup lets you move between talking and typing more smoothly, though you still have to tap “end” to stop voice input. The update is rolling out across web and mobile, with an option in Settings to switch back to the old separate mode.
