ChatGPT o3 is here! And it’s one of the most powerful AI models OpenAI has released. With faster performance, better reasoning, and broader capabilities, it’s already changing how individuals and teams use AI. In this guide, we’ll explore what makes ChatGPT o3 different and how to share access securely and cost-effectively.
In 16th April 2025, OpenAI introduced ChatGPT o3, the latest and most advanced version of its popular AI chatbot model. If you've seen people on Reddit, Discord, or tech blogs talking about “chatgpt o3” or asking how to access the chatgpt new model, you're not alone. This new release has sparked a wave of excitement — and for good reason.
So, what exactly is ChatGPT o3?
To put it simply, o3 is part of a new generation of AI models developed by OpenAI. It’s designed to be smarter, faster, and more capable than anything before it — even GPT-4. With improved reasoning, better memory, and the ability to process more complex instructions, ChatGPT o3 represents a major step forward in how we interact with AI.
But here’s the key thing: ChatGPT o3 is only available in paid plans—Plus, Pro, and Team. If you're on the free tier, you won't get access to this new power. That’s why more people are either upgrading their plans or looking for ways to share ChatGPT accounts with others.
So why is everyone talking about it? Because it feels like the biggest leap since GPT-4. As demand grows, people are looking for smart ways to access o3 and share it with friends, teammates, or clients. And that’s where safe sharing methods (which we’ll talk about later) start to matter.
If you’ve used ChatGPT before, jumping into ChatGPT o3 might feel like switching from a good smartphone to a pro-level camera phone. Everything’s just... better. The responses are sharper, it remembers things more naturally, and it doesn’t get confused as easily.
So what makes ChatGPT o3 so different? And more importantly—how do you actually use those upgrades in real life?
Let’s break it down
We’ve all been there—you have a cool idea, maybe a few bullet points in Notion, but nothing that looks pitch-ready. That’s where ChatGPT o3 really shines.
Instead of giving you generic answers, it can take those rough notes and build out a structured pitch, product summary, or even a slide deck. It organizes your mess into something you’d actually be proud to share.
Prompt idea:
“I’m launching an AI travel planner. Here’s my messy outline—can you clean this up into a startup pitch?”
The result? A clear, confident pitch that sounds like you hired a copywriter. This is where tools like ChatGPT o3 mini come in handy too—lightweight but powerful enough to do serious work, especially on mobile or shared team access.
Writing with o3 is like having a co-writer who actually listens. You give it your voice, your goal, and it delivers content that feels natural—not overly formal, not robotic.
Need a quick landing page? An email that doesn’t sound spammy? A product description with personality? ChatGPT o3’s new model can do it all without needing 10 rounds of revision.
Prompt idea:
“Can you write a fun but professional email introducing my new productivity app to early users?”
Perfect for solo creators, small teams, or even account-sharing setups where multiple people need content quickly but don’t have time to brief a human writer every time.
What really sets ChatGPT o3 apart is how it handles decision-making. Ask it something like “Which payment platform is best for freelancers?”—and instead of giving you a wall of text, it’ll walk you through pros and cons like a smart advisor.
It’s not just copying from Google results, it’s actually reasoning based on what you care about.
And yep, ChatGPT o3 mini high can do this, too. Even on lightweight devices, the performance doesn’t drop.
Prompt idea:
“Compare Stripe vs. PayPal for a freelance business. Focus on fees, ease of use, and client experience.”
This is where o3 becomes more than a tool—it becomes part of how you think through your work.
Let’s say you upload a chart, a graph, or a photo. With ChatGPT o3, it doesn’t just see the image—it understands it. You can ask things like:
“Can you explain what this chart says about sales trends?”
Or even:
“Here’s a screenshot of a product listing. What could be improved in terms of UX or messaging?”
This multimodal upgrade is huge for creators, marketers, or anyone who works visually. No more bouncing between tools. o3 handles it.
Let’s say you’re running a small team — maybe you’re building apps, writing content, designing AI art, or even reselling access to advanced models — and everyone on your crew needs access to ChatGPT o3.
Now sure, you could go the official route with ChatGPT Team, but let’s run the numbers real quick.👉 The Team plan costs $30 per seat, with a minimum of two seats — that’s $60/month minimum. Want 20 people to access ChatGPT o3 through Team? You’re looking at:
💸 20 seats × $30 = $600/month
That’s a lot. Especially for indie founders, student groups, or small AI projects trying to stay lean. The thing is, ChatGPT o3 is already included in all paid plans, whether you're on Plus, Pro, or Team — so you're paying for the same model, just wrapped in a different package.
Instead of spending hundreds on extra seats, savvy users are doing this:
DICloak is especially popular among teams using ChatGPT o3 mini high for daily tasks.
Need to share a single Plus account with 20 users? DICloak has you covered.
Let’s do some quick math:
| Setup | Monthly Cost (20 users) |
|---|---|
| ChatGPT Plus + DICloak | $45 ($20 + $25) |
| ChatGPT Pro + DICloak | $225 ($200 + $25) |
| Official ChatGPT Team Plan | $600 |
Yep — that’s up to 80% cheaper, and you’re getting the exact same ChatGPT o3 access, including all the power of the chatgpt o3 mini model.
For account sellers, small agencies, and bootstrapped teams, this combo offers way more flexibility and you’re not locked into OpenAI’s user-per-seat pricing model.
Sharing access to ChatGPT o3 with your team, clients, or account buyers can be super cost-effective. But it also comes with risks if you don’t do it the right way.
OpenAI doesn’t officially support shared accounts, and they monitor things like login activity, device types, and IP addresses to flag suspicious behavior. If too many people log into the same account from different places or devices, it could trigger a warning—or worse, a permanent ban.
That’s why if you're planning to share access to ChatGPT o3, especially the ChatGPT o3 mini high model on a paid plan, it’s important to protect the account properly.
DICloak has a built-in password manager that keeps your ChatGPT login safe. That means no team member or user can view saved passwords or copy cookies—making it much harder for anyone to steal or misuse your account.
Browser extensions can pose security risks, as some may steal data or compromise your account. By blocking them, you ensure team members can’t install anything that might jeopardise the account or monitor user activity.
Developer tools in browsers let users dig into the code behind a webpage. That’s great for debugging, but not when you’re sharing access to something as valuable as a chatgpt new model account. DICloak blocks access to dev tools to prevent any tampering with your session or login.
Some websites are full of malware, distractions, or even phishing scams. With DICloak, you can block users from visiting blacklisted websites including the Chrome Web Store so they can’t install sketchy extensions or accidentally click into something harmful.
When a team member or client no longer needs access, DICloak can automatically deactivate their profile. This makes sure no one keeps using the account behind your back and helps you stay secure without extra work.
DICloak also offers an API so you can automatically add or remove users from your shared ChatGPT o3 setup. Perfect for account sellers or companies who need to manage access for lots of people quickly and safely.
DICloak updates regularly, and you can make sure everyone on your team is using the same, latest version. That means fewer bugs, fewer support issues, and a smoother experience when using ChatGPT o3 mini together.
Note: This guide focuses on how to share your ChatGPT o3 under the ChatGPT Plus plan account.

Once you're logged into DICloak, head to the dashboard and create a new browser profile. Fill in basic details like:
Setting up a static residential proxy is highly recommended; it helps keep the login IP consistent, which reduces the chance of ChatGPT detecting suspicious login behaviour.
💡 DICloak's lesson: Why is a Static Proxy Important for Account Sharing?
When multiple users access a shared ChatGPT account from different locations, ChatGPT may flag this as suspicious activity. That can lead to login interruptions or even account restrictions.Using a static proxy helps solve this problem. It ensures that every login appears to come from the same consistent IP address, no matter where your team members are. This keeps your ChatGPT account sharing activity stable, private, and far less likely to trigger platform security alerts.
Next, customise your fingerprint settings, including your operating system, user agent, language, timezone, Webgl, device memory, and more. With over 20 fingerprint options to choose from, DICloak helps make each profile look unique and stay consistent.
In the Advanced Settings, make sure to turn on the Multi-open feature to allow several users to access the shared profile at the same time. It is perfect for ChatGPT account sharing across distributed teams.
You can also set default websites (like https://chatgpt.com/) to auto-open whenever the profile is launched.
Tip: Enable cloud sync to store login sessions safely and ensure every member can access the ChatGPT shared account without issues.
Open the newly created browser profile and log into your ChatGPT account. This will store login credentials and cookies, so team members won’t need to enter them again later.
To protect your ChatGPT account and prevent accidental exposure, go to the global browser settings and adjust:
Now it’s time to invite your team. Start by creating a Member Group and assigning basic permissions. We recommend only allowing team members to open or close profiles this keeps access straightforward and secure.
Next, go to Member Settings → Internal Members and add your teammates. Make sure to assign them to the correct Profile Group and Member Group, and define their roles. Once that’s set, just share the login credentials with them.
Make sure you’ve selected the correct Member Group and Profile Group. This ensures your team members have access to the right profiles with the appropriate permissions.
With this setup, it’s easy to manage who can use the shared ChatGPT account, while also preventing unauthorised access or misuse.
That’s it! Your team members can now log into DICloak using their username and password, and start using the ChatGPT account profile you’ve set up.With DICloak, sharing a ChatGPT account is safer and more convenient than ever. You won’t need to worry about multiple users logging in or your account getting flagged. Plus, your personal information stays protected, with no risk of misuse.
