Is this useful if I am using pi coding agent? It can swicth between models mid session?

"Interesting tool! While rate limits are a major friction point right now, I wonder if this is a 'transient' problem. As competition between LLM providers intensifies, we’re seeing a rapid 'race to the bottom' in pricing and massive increases in quotas. Do you think cross-tool handoff remains a viable long-term category, or will it eventually be rendered obsolete by better infrastructure and higher limits?"

what's the point of this? Given the same context, it will again make same errors and backtracking.
