Post-training optimization has also gained relevance. Researchers are developing new methods to enhance model performance after the initial training phase, potentially offering a way to improve capabilities without relying solely on expanding the training dataset.
That said, GPT-5 is still an embryo of a complete model with significant development work ahead. Sam Altman, OpenAI's CEO, has indicated that it won't be ready for deployment this year or next. This extended timeline could prove advantageous, allowing researchers to address current limitations and potentially discover new methods for model enhancement, considerably improving GPT-5 before its eventual release.
