SemiAnalysis: Anthropic Subscriptions Offer 5x More Value Than OpenAI

Subscription Value Analysis

SemiAnalysis reports that Anthropic subscriptions currently offer approximately 5x the API-equivalent value of OpenAI subscriptions for daily users. This finding is based on a detailed comparison of Opus 5.5 versus GPT 6.1 Sol, where Anthropic maintains a significant advantage even after accounting for OpenAI's lower per-token pricing for the Sol class. The analysis highlights that subscription value must be evaluated as a tuple of (plan, model, workload) rather than a static dollar amount, as credit cost ratios differ significantly from API price ratios.

OpenAI's Recent Changes

OpenAI recently implemented a 50% reduction in the API-equivalent value of its $200 subscription plan. Existing subscribers retain their previous limits until October 29, while new subscribers face immediate reductions. OpenAI also introduced a new $500 tier, which offers 21% more Astra tokens than the previous $200 plan but provides lower API-equivalent value for Sol class models due to recent price cuts. The $500 plan's primary feature is 300 TPS Ultrafast performance, currently under testing.

Anthropic's Strategy

Anthropic's approach involves reducing API-equivalent value for premium models, particularly Fable 5.1, where the gap between list price and subscription value is significant. For example, at 100% usage, Opus 5.5 subscriptions could result in a -369% gross margin, whereas Fable 5.1 yields 1%. However, at a realistic 20% average usage rate, margins improve to 6% and 80% respectively. Anthropic has adjusted token limits for Opus models following price cuts, increasing limits by 20% for Max plans and 50% for Pro plans, though this does not fully offset the API price reductions.

Market Context

• Chinese Labs: Offer subscriptions with API-equivalent values approximately 12x lower than OpenAI's, with better value at higher tiers.
• Third-Party Wrappers: Services like Cursor and Cognition (Devin) generally offer worse value than first-party plans.
• Impact on Revenue: Subscriptions account for only 10% of Anthropic's total revenue but consume over 40% of inference compute, significantly impacting blended revenue per MW.
