What is ChatGPT-4.5?

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.

Key Features of ChatGPT-4.5:

Enhanced Context Handling – Keeps conversations on track without losing relevant details, even in complex one-shot prompts.
Improved Data Accuracy – Reduces hallucinations in AI-generated content. Great for text generation, processing, and iteration
Faster Response Time – Processes complex queries with increased efficiency.

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.

What Makes ChatGPT-4.5 So Special?

Consistent Availability Without Restrictions

Chat GPT 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.

More Efficient Prompt Interpretation

Earlier OpenAI models sometimes misinterpreted multi-step instructions or failed to retain relevant details in longer exchanges. With improved prompt adherence, Chat GPT 4.5 follows instructions more precisely, maintains context better, and reduces misinterpretations – a crucial upgrade for multi-branch workflows on Latenode.

Adaptive for Different Tasks with Optimized Context Retention

Chat GPT 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.

Balanced Performance Across Efficiency and Intelligence

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.

Why ChatGPT-4.5 Stands Out: Breaking Down the Benchmarks

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.

More Reliable, Fewer Hallucinations

One of the biggest frustrations with AI is when it confidently gets things wrong – this is called “hallucination.” GPT-4.5 is the most factually accurate OpenAI model yet. In PersonQA, a test designed to see how well AI remembers facts about people, Chat GPT 4.5 scored 78% accuracy, a huge leap from o1’s 55% and GPT-4o’s 28%.

Handling Longer, More Complex Tasks

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, Chat GPT 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.

Sharper Creativity and Tone Adaptation

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.

More Knowledgeable Than GPT-4o, on Par with O-Series

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.

ChatGPT-4.5 VS ChatGPT 4o In Terms of Usecases

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.

Summarization of research papers – ChatGPT 4o processes dense academic texts and generates structured summaries, helping teams get quick insights.
Research synthesis – It assists in comparing findings from multiple sources, making literature reviews easier.
Logical problem solving – ChatGPT-4o does a good job at breaking down complex questions into smaller, more manageable chunks, providing structured explanations. However, it often relies on pattern recognition, occasionally missing deeper contextual relationships between concepts.
Assistance in hypothesis generation – You could use ChatGPT 4o to brainstorm hypotheses based on existing data, but it sometimes generated ideas lacking strong empirical backing or misrepresented causal relationships.

However, ChatGPT 4o had limitations that ChatGPT-4.5 largely solves:

Context limitations – When working with highly interdisciplinary research, the model struggled to maintain deeper connections between different fields.
Limited text length – Unlike GPT- 4.5, the 4o version often truncates long responses, making it difficult to generate comprehensive reviews or lengthy articles. Writers, researchers and marketers had to manually piece together fragmented outputs.
Inconsistent tone – Some texts generated by 4o required manual refinement to align with academic standards. GPT-4.5 is built with better adherence to your guidelines, including the tone and style.
Difficulty with specialized terminology – In some domains, like medicine, science or law, ChatGPT 4o occasionally misinterprets technical language, leading to oversimplified or inaccurate explanations. That is not the case with ChatGPT-4.5, which means better performance at low-code scenarios.
