OpenAI is killing off GPT-4o in two weeks

The model that powered your entire 2024 workflow? Gone February 13th.

GPT-4o, GPT-4o mini, and o1-preview are all getting sunset as OpenAI clears the deck for newer models
If you've been using the API or have custom workflows built on these, you've got 13 days to migrate or break
ChatGPT users on free and paid plans will automatically shift to newer models (no action needed for the chat interface)

This isn't just a version update. OpenAI is aggressively phasing out models that millions of developers and businesses have integrated into production systems. API users need to update their code or face service interruptions.

⚠️ Why this matters: OpenAI is moving faster than your deployment cycle. If you're running 4o in production, this is your wake-up call that "stable" doesn't mean "permanent" in the LLM game. The pace of model obsolescence is accelerating, and two weeks' notice is the new normal.

Quick action: Check your API calls now. If you're hitting gpt-4o endpoints, swap to gpt-4o-2024-11-20 or the latest supported version. Don't wait until February 12th.

Nvidia's $100B OpenAI bet just hit a wall

The biggest AI investment ever planned is now in serious trouble.

Nvidia was set to pour $100 billion into OpenAI, but the deal's now stalled over concerns about OpenAI's shift from nonprofit to for-profit status
The holdup centers on whether OpenAI can legally transition while honoring its original mission and existing investor agreements
If this falls through, it reshapes the entire power dynamic in AI. Nvidia would lose its deepest foothold in the leading LLM company, and OpenAI loses its manufacturing muscle

OpenAI's been trying to restructure from its nonprofit roots into a full for-profit entity to attract massive capital. But that transition is messier than anyone expected, and now one of the biggest checks ever written is frozen mid-air.

⚠️ Why this matters: This isn't just about one deal. If Nvidia can't lock in OpenAI, they'll pivot that $100B somewhere else, maybe Anthropic, maybe their own models, maybe a dark horse we haven't heard of yet.

The AI arms race just got more unpredictable. Meanwhile, OpenAI's restructuring drama shows that even the most hyped startups can't escape their founding DNA without serious legal turbulence.

👀 Watch for: Which company Nvidia courts next if this craters. My money's on them hedging across multiple players rather than going all-in anywhere again.

Instagram finally lets you escape someone's Close Friends list

Because sometimes you don't want to see their 2am rants, and blocking feels too dramatic.

You'll soon be able to remove yourself from anyone's Close Friends list without them getting notified or you having to unfollow/block
Right now, if someone adds you to their inner circle, you're stuck seeing their stories unless you mute, unfollow, or block (all nuclear options)
This is Instagram's quiet acknowledgment that social media intimacy shouldn't be one-sided and viewers deserve control too

The feature is currently in testing and could roll out in the coming weeks. It's a small UX tweak, but it shifts the power dynamic in how we manage digital relationships.

✅ Why this matters: Social platforms are finally realizing that consent goes both ways. Just because someone wants you in their audience doesn't mean you signed up for it. This is part of a bigger trend where platforms give users more granular control over what they consume, not just what they post.

Try this: If you're drowning in Close Friends content you didn't ask for, start muting liberally now. When this feature drops, you can clean house without the awkwardness.
