hey there — i’m niraj 👋
i build software, memes, and sometimes chaos.
but today, i just wanna talk about OpenAI DevDay 2025 — the biggest drop of AI updates this year.
so grab a chai ☕ and let’s break it down like a human, not a press release.
what even is OpenAI DevDay?
it’s OpenAI’s yearly “show-and-tell” day where they roll out all the cool stuff they’ve been secretly building.
this year’s event happened on October 6, 2025, in San Francisco — and yep, the energy was insane.
sam altman took the stage. the internet broke (again).
and now every developer is rethinking what their next AI project could be.
🔥 big reveals that blew my mind
1. ChatGPT turned into an app store
no jokes. ChatGPT isn’t just a chat tool anymore — it’s turning into a full-on platform.
you can now build and host apps inside ChatGPT.
imagine saying:
“find a flat in Surat”
and it pulls data live from a Zillow-like app inside ChatGPT.
that’s wild. and the best part — OpenAI launched an SDK for devs to build these apps easily.
basically, ChatGPT = your new mini-browser for AI apps.
2. agent kit — build your own AI assistant
they dropped something called the Agent Kit, which helps you create your own automated agents.
think of it like building your own Jarvis… but for real tasks:
emails, scheduling, even customer support.
this is where small startups (like yours or mine) can win big — fast, smart, and niche-specific agents.
3. codex just got smarter
remember Codex, the model that writes code for you?
it just got an upgrade — faster, cleaner, and more accurate.
developers everywhere are already calling it “autocomplete on steroids.”
4. OpenAI x Jony Ive (yes, that guy from Apple)
OpenAI’s now working with Jony Ive to design new AI hardware — ambient devices that blend into daily life.
think minimal, elegant, and human-first.
no screens, no chaos — just seamless AI interaction.
5. pulse — your daily AI feed
they also teased a new feature called Pulse inside ChatGPT — personalized daily updates, like a smarter news feed.
no ads yet (thank god).
but if they pull this off right, Pulse could replace your morning scroll through Twitter, Threads, or LinkedIn.
what this means (for builders like us)
| trend | why it matters | what to do |
|---|---|---|
| ChatGPT = app platform | open playground for builders | start building plug-in style AI tools |
| agent automation | mini-assistants are the future | pick a niche + build an agent for it |
| hardware evolution | AI beyond screens | experiment with voice or IoT inputs |
| enterprise shift | companies finally ready to pay | create B2B-ready AI services |
this isn’t just “cool tech.”
it’s the start of AI becoming an ecosystem — where chat, tools, and real-world devices merge.
my honest take
openai isn’t just dropping features — they’re building an operating system for intelligence.
as a builder, this is our cue.
not to compete with OpenAI…
but to build on top of it.
wanna jam on this?
i’m planning to host a small AI jam session soon — where we’ll:
- brainstorm ideas around these new SDKs
- sketch a few agent concepts
- talk about building audience + monetization
if you’re down, drop a comment or DM me.
let’s build something dope — together.
