The shared view suggests that while many people exclusively use Claude, intensely pushing these models to their limits quickly reveals each lab's capability boundaries.
The author's experience is that starting with GPT-5.3, OpenAI shows a distinct advantage in instruction following; however, this doesn't mean it universally outperforms Claude across all scenarios. The key is understanding the nuances between different frontier models to fully leverage their respective strengths.
