Since the beginning of 2025, we have been seeing the launch of one amazing model after another \u2013 from DeepSeek-R1<\/a> and o3-mini to Grok 3<\/a> and Claude 3.7<\/a> Sonnet. The latest addition to this ever-expanding list of advanced AI models is the much-awaited OpenAI GPT-4.5. This new model in the GPT series brings \u201cVibe Check\u201d along with enhanced capabilities to ChatGPT\u2019s chatbot interface. It brings LLM supremacy back to OpenAI as it competes with the latest models like Grok 3 and Claude 3.7 Sonnet<\/a>. In this blog, we will explore the features of GPT-4.5, its performance, how to access it, and even some hands-on applications. We will also see how it compares with other OpenAI models such as GPT-4o, o1<\/a>, and o3-mini<\/a> (high).<\/p>\n

What is GPT-4.5?<\/h2>\n

GPT-4.5 is the latest model by OpenAI and the last model in the GPT series. The first hint of this model was given weeks ago by Sam Altman, when he had released the roadmap for OpenAI. Internally code named \u2018Orion\u2019, this is OpenAI\u2019s last \u201cnon-chain-of-thought\u201d model. This means that unlike other models like o3-mini, Grok 3, or DeepSeek R1, GPT-4.5 gives direct answers without explaining its reasoning step-by-step.<\/p>\n

It relies on learned patterns to produce responses quickly, but may struggle with complex logic-based tasks. It\u2019s trained using \u201cUnsupervised Learning\u201d, to be an inherently intelligent model with better world knowledge. The model also boasts of significantly reduced hallucination rates, along with enhanced contextual knowledge and writing skills. This is why GPT-4.5\u2019s answers sound more natural, without getting over burdened with a lot of reasoning.<\/p>\n

Training Approach<\/h2>\n

Unlike all the latest reasoning models like o1 and o3, GPT-4.5 takes a different training approach. Its core training parts include:<\/p>\n

    \n
  1. Scaled Up Pretraining & Post-training:<\/b> GPT-4.5 is trained using unsupervised learning at a larger scale, leading to better pattern recognition and world knowledge. The model relies on expanded compute and data for training, along with architectural and optimization improvements.<\/span><\/li>\n
  2. Focus on Unsupervised Learning:<\/b> T<\/span>he model relies on scaling unsupervised learning to improve factual accuracy and intuition. This leads to reduced hallucination rates and more reliable responses across various topics.<\/span><\/li>\n
  3. Human Collaboration Training:<\/b> It employs scalable techniques that were developed to train larger models using data derived from smaller models. These methods enhance steerability, making the model better at understanding nuances and following human intent.<\/span><\/li>\n
  4. Reinforcement Learning & Supervision:<\/b> The model uses Supervised Fine-Tuning (SFT) and Reinforcement Learning from Human Feedback (RLHF) to refine responses. Moreover, additional safety techniques ensure responsible AI behavior and minimize harmful outputs. The model was even stress-tested under OpenAI\u2019s Preparedness Framework before release.<\/span><\/li>\n<\/ol>\n

    Key Features of GPT-4.5<\/h2>\n

    Now that we have understood the details regarding the GPT-4.5\u2019s training and its core design, let us look at some of its key features:<\/p>\n
