## Summary

Leiphone tested GPT 6.1 Sol and Claude Sonnet 5.5 through Claude Code on three tasks: a 3D escape room, a policy investigation, and a chemistry explainer. Both models cost the same per token on OpenRouter, yet Sol's total bill was $38.5 against $10.9 for Sonnet 5.5, about 3.5 times higher. The author attributes the gap to differences in agent action paths, such as Sol's extra source archiving and cross-checking, rather than to the price per token.
