If you've been refreshing your feed looking for a massive "GPT-5" drop today, you might be looking in the wrong place. But honestly, what happened today is arguably more important for how your daily apps actually function.
September 26, 2025, marks a weirdly specific turning point in the "AI Wars." It isn't just about faster chatbots. It's about the plumbing—the data, the lawsuits, and the massive infrastructure deals that decide who actually wins the next decade of computing.
The OpenAI Data Retention Deadline
The biggest sleeper hit in ai news today september 26 2025 is actually a legal expiration date. Today, OpenAI's obligation to indefinitely retain consumer ChatGPT and API content—a mandate born from the high-profile New York Times litigation—officially ended.
What does that mean for you? Basically, OpenAI is returning to its standard data retention practices. If you're a privacy nerd, this is a win. The company is no longer legally shackled to keeping every single prompt you've ever typed for the sake of a courtroom discovery process. It’s a return to "normalcy," but it also signals that the legal heat from legacy media is shifting into a new, more manageable phase for the AI giants.
The GitHub Copilot CLI Goes Agentic
If you’re a dev, you probably saw the GitHub Copilot CLI update that went live over the last 24 hours. They’ve moved past simple autocompletion. The new "Agent Mode" in the terminal is now officially in public preview.
I’ve been playing with it, and it's kinda wild. Instead of just suggesting a line of code, you can basically tell it, "Hey, refactor this entire directory to use the new authentication SDK," and it just... does it. It’s not perfect—it still hallucinates the occasional library—but the jump from "fancy autocomplete" to "junior dev in a box" is officially here.
The $100 Billion Infrastructure Boom
You can't talk about ai news today september 26 2025 without mentioning the sheer amount of money being poured into physical hardware. The OpenAI and NVIDIA strategic partnership is hitting high gear today with new details on the "Vera Rubin" platform deployment.
We are talking about 10 gigawatts of power. To put that in perspective, that’s enough to power roughly 7 million homes, all dedicated to training the next generation of superintelligence. While the software gets the headlines, the real story today is the massive power grid expansion required to keep these models running. It's why we're seeing OpenAI team up with SoftBank for $1 billion investments in energy companies like SB Energy.

Why "Nano Banana" is Still Trending
Google’s "Nano Banana" (Gemini 2.5 Flash Image) is still the talk of the town, even weeks after its initial release. Today, new benchmarks surfaced comparing it to ByteDance’s Seedream 4.0.
Honestly, the "Nano Banana" name is still hilarious, but the tech is serious. It's currently the gold standard for on-device image generation. If you've seen those viral 3D figurines all over your social feed today, those are almost certainly generated using the Nano Banana API. It's fast, it's cheap, and it's why Google is currently seeing a massive surge in new Gemini users.
What Most People Are Missing
While everyone is focused on the US and Europe, India just made a massive move. 12 different companies in India just finalized a pact to deploy 38,000 GPUs for a national foundation model. This is about "sovereign AI"—nations realizing they can’t just rely on Silicon Valley forever. They want models that understand local dialects and cultural nuances better than a model trained mostly on Western Reddit threads.
Practical Steps for Your Weekend
The AI landscape is moving way too fast to just "read the news." Here is how you should actually use this info:

- Check your OpenAI settings: Since the data retention order ended today, go into your ChatGPT settings and double-check your privacy and "Chat History & Training" toggles. You have more control now than you did yesterday.
- Test the Copilot CLI: If you’re a coder, install the latest
ghextension. Try the agentic refactoring. It’ll save you three hours of grunt work on Monday. - Audit your "Sovereign" Tech: If you're running a business, start looking at how "local" your AI is. With the rise of national models (like the new Indian pact), the cost of localized API calls is likely to drop significantly in the coming months.
The "move fast and break things" era has been replaced by the "build power plants and win lawsuits" era. It’s less flashy, sure, but it’s how the tech becomes permanent.
