AI 编程工具 Cursor 发布 Composer 2 模型,性能超 Opus 4.6,价格降至前代 14%

Gate News 消息,3 月 20 日,AI 编程工具 Cursor 发布第三代自研编程模型 Composer 2。标准版定价为每百万 token 输入 0.50 美元、输出 2.50 美元,较上一代 Composer 1.5 降价约 86%。同时推出快速版(每百万 token 输入 1.50 美元、输出 7.50 美元),并将其设为默认选项。

Cursor 公布的基准测试显示,Composer 2 在编程 Agent 基准 Terminal-Bench 2.0 上得分 61.7%,超过 Opus 4.6 的 58.0%,但低于 GPT-5.4 的 75.1%。在软件工程基准 SWE-bench Multilingual 上得分 73.7%(上一代为 65.9%),在 Cursor 自研的 CursorBench 上得分 61.3%(上一代为 44.2%)。

Cursor 表示,性能提升来自首次对基座模型进行继续预训练(continued pretraining),并通过强化学习训练模型完成需要数百步操作的长周期编程任务。该模型仅在 Cursor 内可用,不作为独立 API 对外提供。Cursor 的母公司 Anysphere 目前估值 293 亿美元。
