Opus 5.5: is it really a game changer for coding?

A long-time OpenAI user, who has consistently found OpenAI models superior for coding and product development compared to Claude and Gemini, is now inquiring about Opus 5.5. Despite previous experiences where Claude's occasional superiority was temporary and more expensive, the user is hearing significant buzz about Opus 5.5 being a "game changer." They are seeking extensive user experiences to compare its cost and performance to OpenAI models, specifically for coding, and to understand if its real-world usage matches the hype and benchmarks.

Unlike previous Claude versions that offered only temporary and costly advantages, Opus 5.5 is now being discussed as a potential long-term challenger to OpenAI's coding superiority.
