IBM CEO Krishna Says Open-Weight Models Perform Well and Cost Little
IBM CEO Arvind Krishna said the performance gap between open-weight models and frontier models has narrowed from 70 points versus 20 or 30 points in 2024 to 70 points versus 50 points by late 2025. He noted that the token cost of current open-weight models is only 10% to 25% of that of frontier models, while their effectiveness reaches 90% of frontier models. He believes most enterprises will therefore choose open-weight models for the vast majority of routine tasks and use frontier models only for a small number of tasks.
