Qwen3-Coder Has a 1M Token Context Window. Claude Has 200K. Why Am I Still Paying for Claude?

I asked myself this question seriously for the first time when I was loading a legacy monolith into Claude Code for the fourth time in a week watching the context fill up, watching Claude start forgetting earlier files, watching me manually re-paste context like it was 2023. Qwen3-Coder has a 1M token context window. Claude Opus 4.5 has 200K. On a large enough codebase, that’s not a marginal difference that’s whether the entire repository fits in one session or not. And the benchmark gap isn’t what you’d expect either. Qwen3-Coder-Next scores 70.6% on SWE-Bench Verified.
