On October 29, the team subscription and enterprise subscription editions of ByteDance's Doubao Work officially fully integrated third-party models. The first batch launched three external large models: Kimi K3.1Pro, GLM5.3, and DeepSeek V4.1Flash. After the feature goes live, it is enabled by default. Enterprise users do not need to make additional purchases, and the tokens consumed by calls will be deducted directly from the AI points already in their accounts.

This move marks that the office Agent product has broken its previous limitation of relying on a single self-developed model and taken a key step toward a diversified model ecosystem.

As a product that combines Agent DNA from multiple parties, Doubao Work initially supported only the self-developed Doubao large model. After this feature upgrade, platform administrators can refine permissions by member, department, group, or all employees, and can configure model invocation permissions for different office scenarios, including Doubao desktop, mobile, web, and Feishu embedded versions.

Currently, offering diverse model choices to B2B users has become an industry trend. Competitors such as Tencent WorkBuddy, Xiaomi MiMo Desktop, and Alibaba Qwen Office have all successively introduced third-party models. Industry insiders point out that finely configuring different tiers of models can help enterprises effectively manage token costs according to task complexity, achieving cost reduction and efficiency gains amid growing AI computing power consumption.

At the same time, ByteDance is also advancing product integration for enterprise-level services. Coze Enterprise Edition, which belongs to the same ecosystem, announced on the same day that it will stop accepting new customer purchases starting November 30, 2026.
