Summary

The creator found that Claude Sonnet 5.5 can handle his 'create clips from a long video' task and runs much faster than Opus 5.5, so he switched models for that task. The lesson: for routine, well-defined jobs, a smaller, faster model is often enough.

Key points

• Sonnet 5.5 completed the 'create clips from a long video' workflow successfully.
• Sonnet 5.5 was much faster than Opus 5.5 on this task.
• Match the model to the task: if a cheaper, faster model handles it, switch to it.
• Test your recurring tasks on smaller models before defaulting to the largest one.
