IBM CEO Krishna Says Open-Weight Models Perform Well and Cost Little
English text is being prepared.
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.

IBM CEO Arvind Krishna 表示在企业内部部署开放权重模型极具价值。他指出，2024 年闭源前沿模型在性能上显著优于开源方案。前沿模型在基准测试中可能会得到 70 分，而开放权重模型可能只有 20 或 30 分。但到了 2025 年末双方的差距缩小了，不再是 70 分对 20 或 30 分，而是 70 分对 50 分。今天的开放权重模型的 Token 成本仅为前沿模型的 10% 到 25%，而在有效性上达到了前沿模型的 90%。“对任何企业来说，这都是一个简单的问题：如果有一种方案成本仅为顶尖方案的 10%，且有效性达到后者的 90%，你会选择它，还是愿意支付高出 10 倍的成本？”他认为大多数企业会选择避免承担额外的成本。绝大多数常规任务可以使用开放权重模型，而少数任务可以使用前沿模型。
