Introduction
OpenAI has officially launched GPT-4.5, its next-generation general-purpose large language model. This highly anticipated update brings several improvements, including better accuracy, enhanced user interaction, and broader knowledge. OpenAI on Thursday announced the research preview of GPT-4.5, a general-purpose large language model. It will initially be open to software developers and people with ChatGPT Pro subscriptions.
In this blog, we will dive deep into the features, capabilities, and accessibility of ChatGPT 4.5, including details about the ChatGPT 4.5 release, how to use ChatGPT 4.5 free, and information on the GPT 4.5 API.
What’s New in ChatGPT 4.5?
1. Improved Accuracy and Reduced Hallucinations
One of the biggest issues with AI models has been their tendency to generate incorrect information. The model presents inaccurate information less frequently than predecessors, OpenAI said in a blog post. OpenAI has significantly improved GPT-4.5’s accuracy, ensuring that users receive more reliable responses.
2. More Natural Conversations
Early testing shows that interacting with GPT‑4.5 feels more natural. Its broader knowledge base, improved ability to follow user intent, and greater ‘EQ’ make it useful for tasks like improving writing, programming, and solving practical problems.
The AI now understands nuances better, making conversations feel more human-like and engaging.
3. Lower Latency and Faster Responses
Thanks to optimizations in its neural network, ChatGPT 4.5 provides quicker response times without sacrificing accuracy. Whether you’re writing an article, coding, or asking complex questions, GPT-4.5 delivers answers faster than ever.
4. Better Multimodal Capabilities
GPT-4.5 demonstrated a lower hallucination rate than OpenAI’s GPT-4o and o1 models in one test, the company said in a report accompanying Thursday’s release. This means it handles both text and visual inputs more efficiently, making it ideal for AI-driven content creation, image analysis, and more.
5. Integration with Microsoft Azure
GPT-4.5 is available in preview through Microsoft’s Azure AI Foundry, CEO Satya Nadella announced on X. This makes it easier for businesses and developers to integrate GPT-4.5 into their products using GPT 4.5 API.
ChatGPT 4.5 Release Date & Availability
When is ChatGPT 4.5 Releasing?
With over 400 million weekly active users, OpenAI intends to bring GPT-4.5 to those with ChatGPT Plus and Team subscriptions next week, the company’s research lead, Alex Paino, a member of the company’s technical staff, said on a livestream.
Who Can Access It?

Will ChatGPT 4.5 Be Free?
Many users are wondering whether ChatGPT 4.5 free access will be available. At launch, GPT-4.5 is only accessible to ChatGPT Pro and Plus users. However, OpenAI may later introduce a free tier with limited capabilities, similar to previous versions.
GPT 4.5 API: How Developers Can Use It
The GPT 4.5 API allows developers to integrate the new AI model into their applications. Here’s what you need to know:
- Access: Available via Microsoft Azure AI Foundry
- Performance: More efficient with reduced hallucination rates
- Use Cases: Chatbots, AI-powered assistants, automated writing tools, coding support
- Pricing: Expected to be similar to GPT-4 API but with additional features
Sam Altman’s Thoughts on GPT-4.5
Not the Best Model, But Still Impressive
At the same time, the new model won’t be the state of the art in benchmarks, OpenAI co-founder and CEO Sam Altman said in a Thursday X post, describing the model as having “a magic to it I haven’t felt before.”
Future Roadmap for OpenAI
Two weeks later, Altman wrote in an X post that the company wants to get better at sharing a roadmap publicly.
OpenAI has confirmed that GPT-4.5 is a “giant, expensive model,” and the company is working on adding more GPUs to support its rollout. Altman said GPT-4.5 would be coming out, followed by a GPT-5 that would draw on a wider variety of OpenAI’s technology.
Impact on the AI Market
Competition with Chinese AI Labs
The release of the artificial intelligence model comes a month after markets reckoned with the efficient approach employed by Chinese lab DeepSeek. This suggests that AI competition is heating up globally.
Nvidia’s Market Reaction
The market capitalization of Nvidia, whose chips are widely used among AI model developers, declined nearly $600 billion in a single day. This highlights how influential AI developments are on the tech industry.
Conclusion: What’s Next for ChatGPT 4.5?
GPT-4.5 is a significant step forward, bringing more natural conversations, improved accuracy, and better developer tools via the GPT 4.5 API. While it may not be the most advanced AI model ever, OpenAI is setting the stage for GPT-5, which will push the boundaries even further.
For now, if you want to experience ChatGPT 4.5 free, you might have to wait for OpenAI to introduce a free tier. Until then, ChatGPT Pro and Plus users can enjoy the latest advancements.
Stay tuned for more updates on ChatGPT 4.5 release and the future of AI!
