Sonnet 5.5 vs GPT 6.1 Sol: Chess match reveals vast differences in AI token usage

By PulseAugur Editorial · [1 sources] ·

A user conducted a chess match between Anthropic's Sonnet 5.5 and OpenAI's GPT 6.1 Sol, facilitated by MCP. The game revealed significant differences in token consumption and reasoning depth, with Sonnet 5.5 using substantially more output and input tokens, and a much larger portion of its output dedicated to reasoning. Despite Sonnet 5.5's higher token usage, both models made strategic errors, with Sonnet 5.5 overlooking a key defense and proposing an illegal move. The user also noted a stark contrast in subscription usage impact, with Sonnet 5.5 consuming a considerable percentage of their monthly allowance while GPT 6.1 Sol showed minimal impact. AI
