In my experience yes. Been using Claude since day one and wanted to experiment with Pi for fun, and try to get my costs down. I found the open models more expensive, eventually had to plug my Pi set up into an OpenAI subscription, that was the only way to get good value… Then I realised OpenAI is way behind Opus 5.5 and their subscription is far less generous with usage, so I’ve come full circle and am back on Claude Code.
