I've found a better way to work: I only use "5.6 sol ultra-high reasoning" during the planning phase, and use "5.6 Terra ultra-high reasoning" for regular work. Discuss and outline the architecture and workflow with 5.6 sol, and save the discussion results directly as a markdown file. Then, open 5.6 terra and ask it to follow that markdown to complete the specific coding and testing tasks. If it's a long-term development project, you don't really need to set the speed to 1.5x acceleration. Because even with 1.5x acceleration, even 5.6 terra will use up its 5-hour quota. If it runs out, and you don't immediately pull out a magic little card to pay for more quota, but just sit there waiting, it's pointless. Instead, it's better to set it to normal speed and let 5.6 Terra output steadily and consistently. After using it continuously for over 24 hours, I'm very sure that with ultra-high reasoning enabled, 5.6 Terra's performance is significantly better than the previous generation chatGPT 5.5. As for the previous generation GPT 5.5, I honestly don't think it has any issues for work anymore; frankly, it's already sufficient. The main significance of 5.6 for me is during research and discussions; it's a more intelligent collaborator, and its spoken Chinese expression has also improved somewhat. In purely scientific discussions, it's a more reliable partner than 5.5.
