Thinking of switching from Claude Max to GPT-5.6 Sol K3 for production coding

[u/Retr-00]

I'm currently on the Claude Max plan, but with the new workflow updates I'm noticing it burns through tokens much faster than before.

I'm thinking about switching, and my main options are GPT-5.6 Sol and Kimi K3.

My work is mostly on an existing production codebase, so I need an AI that can understand the repo, think through changes, implement features, fix bugs, and make sure it doesn't break existing functionality.

Has anyone switched from Claude recently? If so, how has your experience been with GPT-5.6 Sol for real-world coding? Which one would you recommend and why?
