What do AI subscriptions cost? From $5 to $500 a month

If you want to pay for an AI assistant like ChatGPT, Claude or Gemini, the standard price is around $20 a month. That is according to a price comparison from Fello AI and an article from Notebookcheck. Prices are in US dollars and may look different in Denmark because of VAT and currency.

Around $20 is the norm

According to Fello, ChatGPT Plus costs $20, Claude Pro $20, Google AI Pro $19.99 and Perplexity Pro $20 a month. On Anthropic's own pricing page, Claude Pro costs $17 a month if you pay for a full year at a time, and $20 if you pay month to month.

The cheapest subscriptions, according to Fello, are Google AI Plus at $4.99 (reduced from $7.99 on June 8), ChatGPT Go at $8 and Grok X Subscription Plus at $8. DeepSeek offers a free web chat.

Expensive plans for heavy users

Above the standard tier, it quickly gets expensive. Claude Max 5x starts at $100 a month. According to Fello and Notebookcheck, Max 20x costs $200, but Claude's own pricing page only says "from $100" for both Max plans.

Fello lists ChatGPT Pro in tiers at $100, $200 and $500, Google AI Ultra at $99.99 and an Ultra plan with higher limits at $199.99. Notebookcheck mentions ChatGPT Pro at $200.

The sources disagree on Grok. Fello lists Grok Super at $100 and Grok Ultra at $200, while Notebookcheck in July listed SuperGrok at about $30 and Heavy at about $300. This may be because prices have changed since July.

For businesses, Claude's team plans cost $20 per user per month with annual billing and $25 with monthly billing. Premium seats cost $100 with annual billing and $125 with monthly billing.

For developers: price per million tokens

If AI is used in your own applications, you pay for usage instead. The price is quoted per million tokens, meaning small chunks of text that the model reads (input) and writes (output). According to Fello, GPT-6 Luna costs $0.10 and $0.50, while mid-range models like GPT-6.1 Sol and Claude Sonnet 5.5 cost $2 and $10. The top model GPT-5.5 Pro costs $30 and $180. These API prices were only found at Fello.

Which one is worth choosing?

According to Notebookcheck, the difference lies not in the price but in how you use them. Claude is highlighted for programming, Perplexity for research with source citations, ChatGPT as an all-rounder and Gemini for integration with Google's services.

Fello itself sells a Mac app that bundles ChatGPT, Claude, Gemini, Grok and DeepSeek for $9.99 a month. That information comes from the provider itself.
