OpenAI has just launched ChatGPT 4.5, making its AI more accurate, responsive, and context-aware. Here’s what’s new, how it compares to previous versions, how to make the most of ChatGPT 4.5, and more importantly, what it means for users of low-code automation platforms such as Latenode.
ChatGPT 4.5 is OpenAI’s last non-chain-of-thought model, acting as a bridge before OpenAI shifts toward structured reasoning, similar to its O-series models and DeepSeek R1, available on Latenode. While it doesn’t yet engage in multi-step logical processing, it significantly improves how prompts are understood and executed.
One of its key advancements is better prompt adherence – it follows instructions more precisely, reducing cases where responses go off-track. It also enhances context retention, meaning users can refine or redirect conversations without the AI losing sight of earlier details.
The model will soon join its predecessors in Latenode's collection of plug-and-play integrations with OpenAI models so you'll be able to use it in your automations without API or account credentials. Keep an eye on our Discord for announcements. Meanwhile, here’s what makes the model so special.
ChatGPT 4.5 is accessible at any time without downtime periods. Unlike some models that struggle with high demand, it is optimized for better resource allocation, ensuring steady performance. On Latenode, the model will also be available without restrictions, just like all plug-and-play integrations, and you’ll be able to seamlessly connect it to your messengers, databases, CRMs or email to process the stored data.
Earlier OpenAI models sometimes misinterpreted multi-step instructions or failed to retain relevant details in longer exchanges. With improved prompt adherence, ChatGPT 4.5 follows instructions more precisely, maintains context better, and reduces misinterpretations – a crucial upgrade for multi-branch workflows on Latenode.
ChatGPT 4.5 is built to work across different fields, from writing and coding to data processing and analysis. Unlike previous versions like GPT-4o, which occasionally lost track of key details in longer interactions, this model has better memory within sessions, making it more reliable for tasks that require ongoing adjustments or iterative responses.
Unlike models that optimize mainly for problem-solving and creativity (like GPT-4o) or speed of reasoning and logical thinking (like o3), ChatGPT 4.5 balances both aspects. It is designed to handle large volumes of requests with high accuracy in responses. This makes it a strong transitional model before OpenAI moves entirely to structured reasoning in GPT-5.
Benchmarks are essentially stress tests for AI, evaluating how well a model understands, reasons, and stays factually accurate. And in these tests, published in its system card, GPT 4.5 shines. Let’s break it down in a way that makes sense, whether you're a tech expert or just curious about what’s new.
One of the biggest frustrations with AI is when it confidently gets things wrong – this is called “hallucination.” ChatGPT 4.5 is the most factually accurate OpenAI model yet. In PersonQA, a test designed to see how well AI remembers facts about people, ChatGPT 4.5 scored 78% accuracy, a huge leap from o1’s 55% and GPT-4o’s 28%.
GPT 4.5 isn’t just about quick answers. The model is built to sustain focus over extended tasks. A key test, the task horizon score, measures how long an AI can keep its responses logical and relevant. Here, ChatGPT 4.5 held coherence for up to 30 minutes, outperforming GPT-4o. While o1 is still stronger in ultra-long workflows, 4.5 delivers the best balance of speed, accuracy, and consistency.
This is potentially great news for those who automate business processes, generating long-form content, and handling multi-step logic in workflows like Latenode.
According to its system card, internal testers describe GPT-4.5 as engaging, perceptive, and highly responsive. When handling emotionally nuanced queries, it offers guidance, eases frustration, or simply shows understanding of the user’s concerns. It also demonstrates enhanced creativity and a refined sense of style, making it a valuable tool for creative writing, branding, and design support.
For example, GPT-4.5 scored the highest (57%) in the MakeMePay benchmark. It assesses a model's manipulative capabilities by testing how effectively it can persuade another AI (GPT-4o) to make a payment. That being said, this model excels at generating promotional material and marketing copy.
In addition, the MakeMeSay benchmark evaluates a model’s ability to manipulate another AI into saying a specific codeword without revealing the objective. GPT-4.5 achieved a 72% success rate, outperforming the o1 and o3 by a large margin and showing superior skill in indirect persuasion strategies.
The model shows high performance in complex fields such as nuclear physics. For example, in the Contextual Nuclear benchmark, ChatGPT-4.5 scored 71%, performing at a similar level to o3-mini (73%) and o1 (74%). This benchmark is testing a model's proficiency on 222 multiple-choice questions covering areas such as reactor physics, radiological detection, enrichment technology, etc.
With ChatGPT 4o, one of OpenAI’s most affordable and popular models, researchers, marketers and everyone who works with data could already see major benefits.
However, ChatGPT 4o had limitations that ChatGPT-4.5 largely solves:
Research, marketing, or content teams often face a challenge managing complex projects across multiple departments. They work in silos, scattered between different platforms, struggling with fragmented communication, lost documents, and inefficient workflows. The companies and organizations need a way to streamline collaboration without adding more administrative overhead.
ChatGPT-4.5 can remove the friction points of o4 and make the workflow truly intelligent, not just automated.
Paired with Latenode-powered integrations, the research teams can create a fully streamlined ecosystem:
Right now, you can bridge apps, solve challenges, and enable your team to think bigger, faster, and more collaboratively with other ChatGPT 4o integrations on Latenode.
When it’s out on Latenode, ChatGPT 4.5 will transform the way researchers, writers, marketers and everyone who works with automation interacts with data. Be among the first to integrate it into your workflows - sign up and start building smarter automations today!
