An Artificial Analysis benchmark chart compares Sonnet 5.5, Haiku 5.5, GPT-6.1 Sol and GPT-6.1 Terra across reasoning efforts: Terra is massively faster than Sol (91 vs 61-81 tokens/s) and cheaper per task (e.g. $0.26 vs $0.59 at High), while Sol scores higher on intelligence (55 vs 51 at Max). The author argues most enterprise clients don't need the best model — they want good-enough at the lowest cost for customer service and routine office work, making cost per token the decisive metric.
