Claude Max and ChatGPT Pro subscriptions cost 40-70x API rates
SemiAnalysis shows a $200 sub is worth $8,000-$14,000 in API usage.
In January, researchers calculated the real cost of Claude Code subscriptions when converted to API rates, finding a $200/month subscription would cost roughly $2,700 at API prices. SemiAnalysis has now repeated the experiment across all provider tiers using extended coding tasks until weekly limits were exhausted. The current figures are noticeably higher: for Anthropic, the number has nearly tripled to $8,000/month for Claude Max 20x, and for OpenAI, ChatGPT Pro now draws an eye-popping $14,000/month via API—a 70x multiple over the $200 subscription price.
These findings highlight the massive discount subscription users receive compared to direct API consumption. SemiAnalysis believes this unprofitability will push providers to reserve all new models and features for API users exclusively. Additionally, Fable (Mythos), a popular feature, will disappear from subscriptions starting June 22 and only be available via extra usage. For power users, this shift could mean losing access to cutting-edge capabilities unless they switch to costly API plans.
- SemiAnalysis found Claude Max 20x subscription ($200/month) costs 40x less than the API equivalent ($8,000/month).
- ChatGPT Pro subscription ($200/month) costs 70x less than its API equivalent ($14,000/month).
- New models and features may be held back from subscriptions; Fable (Mythos) will be removed from subscriptions on June 22.
Why It Matters
Subscription AI services offer huge discounts, but advanced features may shift to API tiers, reducing value for casual users.
