My New Hobby: Challenging AI Code Assistants

This article describes a developer's hobby of pitting AI code assistants against each other to solve coding problems. The author compares OpenCode and Cursor, noting that Cursor consumes 5-6x more tokens and introduces unnecessary code and bugs. A specific bug fix cost $4.5 and 6.9M tokens with Cursor, while OpenCode fixed it with 35k tokens. The author critiques Cursor's harness as inefficient and noisy, despite its cheap model, and suggests it may only be suitable for creating new features, not simple bug fixes.
