ByteDance's AI office agent app Doubao Work said on October 29 that it is opening third-party models to business customers, adding Kimi K3.1 Pro from Moonshot AI, GLM-5.3 from Zhipu, and DeepSeek-V4.1-Flash as the first batch1. The models appear in the app's model picker alongside ByteDance's own Doubao models and are available on team and enterprise subscription plans, switched on by default.
Unified billing and admin controls
Companies do not need to buy access from each model provider or file a separate application. Usage is deducted from the AI credits the organization already holds in Doubao Work. Administrators can control who uses which model, granting access at the level of individual members, departments, groups, or the entire company. They can also enable every model from a single provider at once or set up one model on its own.
ANALYSIS The single-bill, single-permission-system design removes much of the procurement friction enterprises face when evaluating multiple model vendors side by side. It also positions Doubao Work's agent layer — which can work across files, browsers, and desktop apps — as the primary product, rather than any single underlying model.
Shift in product positioning
Until now, Doubao Work had been largely a showcase for ByteDance's own Doubao models. Letting enterprises route tasks to rival Chinese models reframes the app as a model-agnostic orchestration surface. Teams can now choose a model by task — for example, a coding-focused model for engineering work and a different model for long documents.
ByteDance did not say which additional third-party models would follow the first batch.
Parallel moves across Chinese agent tools
The update fits a wider pattern among Chinese desktop agent products. Xiaomi's MiMo Desktop added DeepSeek, GLM, Kimi, and Qwen models the same week. Several other agent tools have made similar moves.
Doubao Work has also added recent feature updates including an infinite creation canvas, one-click import of chat history, skills, and memory from other AI tools, and the ability to save recorded computer actions as reusable skills.
DeepSeek recently cleared Beijing's AI export registration for overseas deployment[3].
