Microsoft’s Copilot has yet to add a true Deep Research option; its Think Deeper skill is essentially a lightweight version. Lightweight limitationsPreviously, ChatGPT’s Deep Research had a few drawbacks. It was available only to paid subscribers with Plus, Team, Edu, and Enterprise plans. It also limited the number of queries you could submit per month — 120 for Pro users and 10 for other subscribers. Depending on your question, Deep Research could take as long as 30 minutes to deliver results. However, the new lightweight version helps overcome these barriers.

Once you reach your limit for the full version of Deep Research, your queries automatically default to the lightweight version. Moreover, the lighter version is much quicker than the full one.

    Netflix introduces a new ‘dialogue only’ subtitles option (crowd cheers)

    Elyse Betters Picaro / ZDNETNearly half of all Americans use subtitles when they watch TV, a recent study showed, so Netflix is making them even better.In a blog post this week, Netflix announced a new subtitle option — dialogue only. Also: I discovered Netflix’s secret genre codes and my watchlist exploded – how they workRight now, if you turn on subtitles, you’ll see not just words that are spoken, but other audio cues like [cell phone rings] or [dog barks] ([or squelching noises] for Stranger Things fans). You’ll also see the names and titles of songs that play. With the new setting, captions will only display spoken words. No background sounds will appear. It’s a small change, but it’s an improvement for the many people who turn on captions to make sure they catch every word over the bustle of kids, dogs, or other family members around them, or people watching with lower volume at night. Also: The best Netflix VPNs: Expert tested and reviewedIt’s not just background noise causing difficulty, though, as a New York Times report indicates the issue stems largely from the way audio is mixed for cheaper televisions and phones.
