The platform aims to help users quickly build and deploy AI applications and lower the barrier to AI usage.

Tongyi Qianwen offers several flagship models, including Max, Plus, Flash, and Coder. Tongyi Qianwen Max is suitable for complex tasks and has the strongest capabilities; Plus strikes a balance between performance, speed, and cost; Flash is suitable for simple tasks, is fast, and extremely low-cost; Coder is an excellent code model, adept at tool invocation and environment interaction. These models differ in context length, input/output pricing, etc., allowing users to choose based on their actual needs.

Tongyi Qianwen provides various models for text generation, including commercial versions (Max, Plus, Flash), open-source versions (Qwen3, Qwen2.5), and the ultra-long document model Long. These models are suitable for different text generation tasks, such as article creation, dialogue generation, and text summarization.

The Alibaba Cloud Bailian platform not only provides the Tongyi Qianwen series models but also integrates third-party models such as DeepSeek, Kimi, and GLM-4.5, offering users more choices. These third-party models have advantages in specific domains and can meet users' diverse needs.

The pricing of Tongyi Qianwen models varies depending on the model type, version, context length, and the number of input and output tokens. Flagship models like Max, Plus, and Flash have their own pricing strategies, allowing users to choose the appropriate model based on their actual usage. Some models also offer tiered pricing, where the unit price decreases as the number of tokens increases.

The Alibaba Cloud Bailian platform provides new users with a certain free quota, including the number of tokens and validity period. Users can experience the functions of various models within the free quota. After the free quota is used up, users need to pay according to the prices stipulated by the platform.

Choosing the right model requires considering the complexity of the task, the requirements for speed and cost, and the required modality. For complex tasks, Tongyi Qianwen Max or Plus can be chosen; for simple tasks, Flash can be chosen; for code generation tasks, Coder can be chosen; for multimodal tasks, VL, Audio, or Omni can be chosen. At the same time, attention should also be paid to factors such as the model's context length, input/output pricing, and free quota.
