Real-world math: GPT-6.1 Terra's half price is offset by 2-3x token usage, costing more than Sol

A Reddit user compared GPT-6.1 Terra (Xhigh) vs GPT-6.1 Sol (Medium) using Artificial Analysis data. Terra scores slightly lower across benchmarks (Terminal-Bench 46% vs 48%, HLE 44% vs 50%, SciCode 53% tie) despite costing half per token ($5/$1 vs $10/$2 per 1M output/input). But reaching 'similar' intelligence requires bumping Terra to xhigh, burning 2-3x more tokens — so 'cost to run intelligence index' ends up higher ($365 vs $361). Verdict: Terra is fine for simple, well-specified tasks, but as a Sol replacement it's a false economy.
