Claude Opus 5 vs GPT-5.5: Same $5 In, Who Wins Out?

I'm calling this one for Claude Opus 5 if you write code for a living, and for GPT-5.5 if you'd rather pay for cheaper output on agent-heavy work. Opus 5 charges $25 per million output tokens against GPT-5.5's $30. Small gap on paper, real gap on a busy week. Neither dominates everything, but the value flips depending on your workload. Let's break down where each earns its keep.

Never did trust a number you could argue both ways, but the code-vs-agents split rings true. Reminds me of sorting honest claims from padded ones — the same $5 buys different work depending who's holding the pen. I'd pay the extra for code that holds up.
