ByteDance's Volcengine Ark Coding Plan has launched GLM-5.1, integrating multiple domestic large models like Minimax M2.7 and DeepSeek-V3.2. This update allows developers to access leading models with a single subscription, reducing trial costs. However, users report issues with resource limits and service quality, highlighting challenges in the "model supermarket" approach. Major cloud providers, including Alibaba Cloud and Tencent Cloud, are advancing multi-model integration strategies. Alibaba's "Bailian Coding Plan" and Tencent's updated subscription services reflect a shift towards "model marketplaces." This trend emphasizes platform integration over individual model capabilities, with competition focusing on service stability and ecosystem capabilities.
