Users report severe usability issues with Claude Opus 5, suggesting the "just scale more" approach may be hitting a wall in user experience.
- Verbose Output: Despite instructions to be concise (e.g., using Zinsser's style), the model produces extremely wordy and frustrating outputs.
- Functional Failures: The model reportedly argues with instructions, stops mid-task, and behaves unusably, leading some users to cancel subscriptions.
- Divergence: While benchmark scores may rise, the daily utility is declining, raising questions about the effectiveness of scaling laws for practical use.
