Real User Reviews: ChatGPT 5.5 vs Claude Opus 4.7 (April 2026)
REDDIT . r/OpenAI & r/singularity
“GPT-5.5 is the first model that actually feels like it understands what I’m trying to do. It debugged a 3-day bug in one shot and explained exactly why previous attempts failed.”
– Dan Shipper, CEO of Every
X / TWITTER . DEVELOPER
“Opus 4.7 still feels rock-solid for architecture, but GPT-5.5 is noticeably more hands-off on heavy execution. Claude is the senior architect; GPT-5.5 is the all-round executor.”
