OpenAI to Release GPT-4.5 and GPT-5 — Here’s How It Works

The Biggest AI Leap Yet: OpenAI’s Roadmap for GPT-4.5 and GPT-5

Artificial intelligence is evolving faster than ever, and OpenAI just confirmed its most ambitious AI roadmap yet—the release of GPT-4.5 and GPT-5.

These new AI models promise to deliver unmatched intelligence, better usability, and a unified experience for users. If you’ve been frustrated with choosing between different models, OpenAI is about to simplify everything.

But how do these updates change AI as we know it? What are the key differences between GPT-4.5 and GPT-5? And what does this mean for ChatGPT free users, Plus subscribers, and Pro users?

Let’s break it all down.

What Is OpenAI’s Plan for GPT-4.5 and GPT-5?

OpenAI is eliminating complicated AI model choices and creating a seamless, all-in-one AI system.

Here’s what’s coming:

• GPT-4.5 (Internally Called Orion): The final non-chain-of-thought model before OpenAI shifts towards unified intelligence.
• GPT-5: A next-generation AI model that merges different AI tools, making ChatGPT and OpenAI’s API more powerful than ever.
• No More Model Picker: OpenAI admits that selecting different models has made AI unnecessarily complicated. They plan to return to a “magic unified intelligence” experience.

The goal? AI that “just works” without needing manual adjustments.

When Will GPT-4.5 and GPT-5 Be Released?

While OpenAI has not given an exact release date for GPT-4.5 and GPT-5, here’s what we know:

what we know:

1. GPT-4.5 (Orion) is coming first – This will be the last model before OpenAI transitions to a fully integrated AI system.
2. GPT-5 will follow soon after – It will unify OpenAI’s different AI models and bring major new capabilities.
3. ChatGPT Free Users Will Get GPT-5 – OpenAI confirmed that GPT-5 will be available for free users, but at a standard intelligence level.
4. ChatGPT Plus and Pro Will Get More Power – Paid subscribers will have access to higher intelligence levels with GPT-5.

How Will GPT-5 Be Different from GPT-4.5?

GPT-4.5 vs. GPT-5: What’s Changing?

How Will GPT-5 Be Different from GPT-4.5?

GPT-4.5, known internally as Orion, is OpenAI’s last non-chain-of-thought model, improving speed, accuracy, and context retention. However, it still operates separately from OpenAI’s O-series models.

GPT-5, on the other hand, will unify OpenAI’s AI models, eliminating the need for a model picker. It will integrate voice, search, deep research, and advanced reasoning, making ChatGPT smarter and more intuitive.

While GPT-4.5 enhances what GPT-4 started, GPT-5 takes AI to the next level, offering more intelligent, seamless, and context-aware responses across all user tiers.

OpenAI is getting rid of standalone models like O-series and integrating everything into GPT-5.

This means AI that knows when to think for a long time, when to generate instant responses, and when to use tools like voice and deep research.

Will GPT-5 Be Free? What About ChatGPT Plus and Pro?

Yes—GPT-5 will be available for free users, but with limitations.

Here’s how OpenAI is structuring access:

• ChatGPT Free Tier → Unlimited GPT-5 access (standard intelligence level, subject to abuse thresholds).
• ChatGPT Plus Subscribers → Higher intelligence level access.
• ChatGPT Pro Users → Even more advanced intelligence and AI capabilities.

If you want the most advanced version of GPT-5, ChatGPT Pro will be the best option

Why OpenAI Is Removing Standalone AI Models

OpenAI’s announcement confirms a major shift—no more standalone O-series models.

Instead of releasing separate AI models, GPT-5 will:

• Unify all OpenAI’s AI tools into one system.
• Make AI decisions smarter and more intuitive.
• Eliminate the need for a model picker.

Sam Altman and OpenAI’s team have made it clear—they want to make AI work without friction.

What Can GPT-5 Do? OpenAI’s Next-Gen AI Features

GPT-5 will introduce a new level of intelligence, with:

✅ Advanced Reasoning – Better at handling complex, multi-step questions.
✅ Integrated Search & Deep Research – Can pull real-time information like Google Search.
✅ Voice & Visual Capabilities – ChatGPT won’t just be text-based—it will understand and respond to voice and visual input.
✅ Smarter Decision-Making – The AI will know when to think longer and when to respond instantly.
✅ Better AI Memory – Retains past conversations and remembers context better than GPT-4.

These upgrades mean GPT-5 will feel more like a personal AI assistant than ever before.

How Will GPT-5 Change ChatGPT and AI?

If you’ve used ChatGPT, you know the frustration of:

• Switching between models.
• Limited real-time information.
• AI responses that feel robotic or inconsistent.

GPT-5 fixes these problems by:

🚀 Making ChatGPT smarter, faster, and more human-like.
🌎 Unifying OpenAI’s AI models into one seamless system.
📢 Giving free users access to a powerful AI model (without needing a subscription).

This is OpenAI’s biggest AI leap yet.
