Alibaba's proprietary Qwen3.7-Max can run for 35 hours autonomously and supports external harnesses like Anthropic's Claude Code

Alibaba’s Qwen Team released Qwen3.7-Max, a proprietary AI model that it says can sustain about 35 hours of continuous autonomous execution for complex agentic tasks. Unlike earlier Qwen releases, the model is not open source and is available through Alibaba-controlled access points, positioning it closer to paid frontier offerings from OpenAI and Google.

The release shows how leading labs are shifting from chatbots toward long-running agents that can plan, execute, and recover over extended workflows. Alibaba’s move away from open source may improve monetization, but China-based endpoints could limit adoption among Western enterprises with strict compliance, security, or data residency requirements.
