OpenAI's GPT-5 Development Faces Delays and Data Challenges

The ambitious AI model, codenamed Orion, struggles with high costs, insufficient training data, and internal setbacks, raising concerns about its feasibility.

• OpenAI's GPT-5, also known as Orion, has been in development for over 18 months but remains behind schedule and over budget.
• The company faces a major obstacle: a lack of sufficient publicly available data to train the model, leading to the creation of synthetic data and custom datasets, which have yielded mixed results.
• Training costs for Orion have skyrocketed, with a single six-month training run estimated at $500 million, far exceeding GPT-4's $100 million training cost.
• Internal turmoil at OpenAI has compounded challenges, with over two dozen key executives and researchers departing this year, including co-founder Ilya Sutskever and CTO Mira Murati.
• Rivals such as Anthropic and Google have made significant progress, with some in the industry rating their models as more advanced than OpenAI's GPT-4.
