Claude Sonnet 4.5 beats Qwen 3.5 in coding tests.

This is less about raw benchmark bragging and more about who breaks less when workflows get messy in real coding sessions.

• –Anthropic’s official release emphasizes sustained coding performance, agent workflows, and computer-use gains, which aligns with the video’s “completion + recovery” framing.
• –In practical dev work, error recovery quality often matters more than first-pass speed because it determines whether agents can finish tasks without manual rescue.
• –Qwen 3.5 remains a serious challenger on openness and value, but this comparison suggests a remaining gap on robustness in longer coding runs.
• –Teams should treat this as directional signal, then run repo-specific evals before standardizing model choice across production tooling.
