Pros & Cons from Real Users

Pros

  • GPT-5.5 has been outstanding for AI agents and coding work. It feels smarter, more persistent, and better at handling complex technical tasks than previous models. I use it for debugging, writing code, planning agent workflows, and working through multi-step software problems. It is especially strong when I need clear reasoning, structured output, and practical code that I can actually use.

Cons

  • GPT-5.5 still works best with clear instructions and enough project context. For large codebases or production-level changes, I still review the code carefully before shipping it.
