Introduction of GPT 4.5 and Its Implications

GPT 4.5 has been announced as OpenAI's latest iteration, representing a significant advancement in the field of large language models. While the model boasts an increase in size and improved performance, it lacks the reasoning capabilities found in newer models, leading experts to suggest that simply scaling up may not yield game-changing advancements. Its benchmarks indicate moderate performance improvements, but the model is criticized for its high processing costs and relatively slower response times. Ultimately, experts are beginning to question the effectiveness of merely increasing model size without enhancing underlying reasoning capabilities.
