OpenAI launched three GPT-4.1 series models, as well as new reasoning models o3 and o4-mini, achieving significant optimizations in multimodal processing, code capabilities, instruction following, reasoning, and cost. At the same time, the scaling law on the inference side is still ongoing during the development of the o3 model, verifying the correctness of the direction of expansion of the reinforcement learning paradigm. The average daily token call volume of the Doubao large model has exceeded 12.7 trillion, which is three times that of December 2024. The launch of the Doubao 1.5 Deep Thinking model is expected to further promote user usage. Alibaba AI open source community MoDa launched the new MCP Plaza on April 15, exclusively launching new MCP services such as Alipay and MiniMax, continuing to accelerate the expansion of the MCP ecosystem. CICC believes that MCP accelerates the development of the AI industry. 1) It is beneficial to software companies that have data, customers, and scenarios. AI products are expected to drive the company's ARPU increase and project unit price increase; 2) The demand for model privatization increases, which is beneficial to all-in-one machines, hyper-convergence, and B-side service outsourcing companies.
