The open-source model ecosystem has become a focal point of global AI governance: OpenAI and Anthropic have reportedly lobbied to restrict open-source AI models, while over 20 tech giants—including Microsoft, NVIDIA, and Meta—have jointly endorsed open-weight models [1][6][21]. Meanwhile, Alibaba's Qwen AI Platform enables unified orchestration of 100+ models and autonomous Agent invocation, generating short videos in just 15 seconds [2]; the Claude Code team reduced system prompt length by over 80% without sacrificing performance, redefining context engineering paradigms [13][14].
