Brace yourselves, tech enthusiasts, as OpenAI is about to release its newest and most impressive AI language model yet – GPT-4.5. This revolutionary model boasts of better writing capabilities, improved world knowledge, and a refined personality compared to previous versions.
But wait, before you get too excited, OpenAI wants to make it clear that GPT-4.5 is not a frontier model and may not perform as well as some of its predecessors. However, with its advanced pattern recognition abilities and problem-solving skills, this model is ideal for tasks like writing, programming, and practical problem-solving.
According to leaked documents from the company ahead of the official announcement, GPT-4.5 has been trained using new supervision techniques along with traditional methods like supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF). This approach has resulted in significant improvements in computational efficiency compared to its predecessor GPT-4.
But what about hallucinations? Well, according to OpenAI’s research team member Raphael Gontijo Lopes during the company’s livestream event, GPT-4.5 hallucinates much less than its predecessor models but slightly more than their o1 reasoning model.
Interestingly enough,GPT-4.5 will only be available for ChatGPT Pro users initially,similarly how Operator was released previously.This aligns with OpenAI’s plans of eventually integrating all their technology into one system – the highly anticipated GPT-5 which might be launched as soon as late May according to reports.
CEO Sam Altman has hinted at incorporating their latest o3 reasoning model in the upcoming GTP-5 system during the 12 days of Christmas announcements last December.OpenAI also recently released o3-mini last month,but it seems like o3 will only be included in GPT-5.
This aligns with OpenAI’s ultimate goal of creating an all-encompassing model that could potentially be labeled as artificial general intelligence (AGI). So while GPT-4.5 may not be a frontier model, it is certainly a step closer towards OpenAI’s grand vision. Get ready to experience a warmer, more intuitive and emotionally nuanced conversation with the launch of GPT-4.5 – the largest and most knowledgeable AI language model by OpenAI yet.
