GPT-4.5 marks a significant advancement in OpenAI's AI models, emphasizing a strategy of increasing size and complexity. Launched as a research preview, the model requires a $200 monthly subscription to access. Unlike competing models that prioritize efficiency and cost-effectiveness, OpenAI focuses on maximizing model capabilities to improve emotional nuance and interaction understanding. Key features include web search capabilities, file uploads, and improved reliability, with investments in infrastructure to support future model expansion.
If you know more things, you don't need to make things up," says Mia Glaese, who leads OpenAI's alignment team and human data team. This underscores the design philosophy behind GPT-4.5, aimed at reducing hallucination by increasing model size.
OpenAI promised to invest billions into building the AI infrastructure required to fuel more massive models, reinforcing its commitment to 'bigger is better' in AI development strategies.
