[Analysis: Anthropic's subscription plan offers approximately 5 times the value of OpenAI's] According to a report by SemiAnalysis, after testing subscription quotas from multiple AI companies, it was found that based on API equivalent value calculations, Anthropic's Opus 5.5 subscription at the same tier offers over 5 times the value of OpenAI GPT-6.1 Sol. The report states that OpenAI recently halved the $200 Pro tier quota; subscriptions account for only about 10% of Anthropic's revenue but can occupy over 40% of its inference compute capacity.
