AI21 与 Deel 联手后训练 Nemotron 3.5 Super，3 周在薪酬领域超过 Claude Opus 5.5
AI21 拿 NVIDIA 的 Nemotron 3.5 Super 做后训练，只花 3 周就在薪酬领域跑赢了 Claude Opus 5.5。做垂直场景落地的团队可以看看他们怎么把领域数据和后训练流程结合的。
AI21 Labs 宣布与薪酬和 HR 合规公司 Deel 合作，基于 NVIDIA 的 Nemotron 3.5 Super 进行后训练，仅用 3 周时间让模型在全球薪酬（global payroll）领域的表现超过 Claude Opus 5.5。两家公司分工明确：AI21 提供多年积累的模型后训练经验，Deel 提供薪酬与合规领域的专业知识。
合作细节在 NVIDIA GTC Berlin 上披露，AI21 联合创始人兼 CEO Ori Goshen 与 Deel 的 Matias Michael 进行了对谈。这条路径被 AI21 称为'owned intelligence'——即企业通过后训练获得自有的垂直领域模型，而不是直接调用通用大模型。
对开发者与企业买家的启示是：通用旗舰模型在细分合规领域并非不可超越，选对基础模型并注入领域数据，3 周即可在特定基准上拿到领先成绩。这类垂直后训练案例对考虑自建模型的企业有直接参考价值。
👉 We brought years of model post-training expertise. 👉 @emetbydeel brought leading payroll and HR compliance domain expertise.
🤝 Together, we post-trained @nvidia's Nemotron 3.5 Super to surpass Claude Opus 5.5 on a global payroll model in just 3 weeks. Co-founder and CEO @origoshen sat down with @emetbydeel's @_MatiasMichael at @NVIDIA GTC Berlin to discuss how.
