OpenAI's next-generation Orion model of ChatGPT, rumored to arrive by the end of the year, may not live up to expectations.According to a report, Orion shows a smaller improvement over its predecessor, GPT-4, compared to the improvement seen between GPT-4 and GPT-3.Orion is stronger in general language capabilities but doesn't perform reliably better than GPT-4 in coding applications.The AI industry is facing a training data bottleneck, as the supply of high-quality text and data for training new models is dwindling.
