Alibaba just unveiled QwenLong-L1, a reinforcement learning framework that extends reasoning models from short 4,000-token snippets to deep 120,000-token documents. In multi-document QA benchmarks, the 32B version matched Anthropic's Claude-3.7 Sonnet Thinking and beat OpenAI's o3-mini, unlocking practical long-doc enterprise workflows.
