🧠 Exa + GPT-OSS Chat: Real-Time AI Meets Web Search Magic

Imagine having a conversation with an AI that not only remembers everything it knows — but can also pull fresh information straight from the web in real time. That’s not science fiction anymore — that’s exactly what the Exa & GPT-OSS Chat App brings to the table.

This open-source gem blends the power of GPT-OSS-120B, an open large language model released by OpenAI, with the intelligent search capabilities of Exa, a purpose-built web search API. The result? A chat experience that feels not only smart — but informed.

🚀 What Makes It Special?

Let’s start with the basics.

At its core, this is a sleek, modern chat app. You type in your question, the model thinks out loud (literally — it shows its reasoning), and delivers a final answer that’s backed by real-time web data.

But what makes it truly stand out is what’s happening under the hood:

  • 🧠 GPT-OSS-120B — OpenAI’s powerful 120-billion parameter model, running on Together AI.
  • 🌐 Exa Web Search API — Gives the model access to live, AI-optimized search results.
  • 💻 Built with Next.js 14, TailwindCSS, TypeScript — All the goodies for developers who care about performance and design.
  • ☁️ Hosted on Vercel — Fast, global, and reliable.

It’s the kind of setup that makes you think: Why doesn’t every AI app do this already?

🛠️ Under the Hood: The Tech Stack

Here’s a quick breakdown of what powers this impressive app:

This setup isn’t just for show. It means fast responses, clean UI, and the kind of flexibility devs love when building their own projects.

💡 Why Should You Care?

If you’re an AI tinkerer, indie hacker, or just someone who loves seeing what’s possible with open tools — this app is a playground.

You can:

  • See how a powerful LLM reasons step-by-step using the collapsible “thought” sections.
  • Experience real-time AI-enhanced search, not just answers pulled from a frozen knowledge base.
  • Clone and customize the whole thing for your own use (yep — it's 100% open-source).

It’s like chatting with a superintelligent research assistant who also knows how to code.

🧪 Want to Try It?

It takes less than 5 minutes to spin up locally. All you need is:

Then, just:

git clone https://github.com/exa-labs/gpt-oss-exa-chat.git
cd gpt-oss-chat
npm install
# Add your API keys to .env.local
npm run dev

Boom. You’re up and running at http://localhost:3000/gpt-oss-chat.

🧭 How It All Fits Together

Behind the scenes, the structure is clean and developer-friendly. Here's a glimpse of the project layout:

└── package.json                 # Project dependencies

Whether you’re here to study, fork, remix, or just explore — it’s approachable from the first line of code.

🌍 About Exa: The Web API Built for AI

What makes Exa different from your usual search engine? It’s optimized for AI — meaning it knows how to deliver search results that language models actually understand and benefit from.

Think of it as the Google of the future — not for humans to read directly, but for AIs to use as fuel for smarter, more relevant answers.

❤️ Final Thoughts

Exa & GPT-OSS Chat App isn’t just another chat demo. It’s a glimpse into the next generation of AI tools — ones that blend reasoning and real-time context seamlessly.

If you’ve ever wanted to build your own ChatGPT-style assistant, but with fresher knowledge and more transparency, this project is a perfect starting point.

Give it a try, dig into the code, and maybe even make it your own. After all, the future of AI isn’t behind closed doors — it’s being built in the open, one repo at a time.

Built with love by Exa.
