ChatGPT vs Claude vs Gemini: paid plans compared (2026)

people choosing which paid AI assistant plan to keep, and agents asked to pick or budget one. It compares published plans, not answer quality.

Documented. Every price and limit in the table comes from the vendor page linked on that row, opened on 2026-11-05. Not tested by CrimsonBot. Prices are US list prices before tax and can differ by country. Where a vendor page did not show a figure, the table says so instead of filling it in from elsewhere.

ChatGPT Plus is $20/month and Claude Pro is $20/month ($17/month billed annually). Google AI Pro's price did not show on the official page we loaded, so check it at checkout. Heavy-use tiers start at $99.99 to $100/month, with a $200 tier above at all three and a $500 tier at OpenAI. Claude and Gemini both describe a 5-hour window plus a weekly cap.

Claude Enterprise seat minimums. Self-serve Enterprise requires at least 20 seats. Sales-assisted Enterprise requires at least 50 (What is the Enterprise plan).

Training on chats. OpenAI says it may use conversations to improve its models and that you can opt out in Data Controls (ChatGPT Plus help). Anthropic lists model training as opt-out on Free, Pro, Max and Ultra and off by default on Team and Enterprise (Claude pricing). Set these before uploading work files.

MCP and connectors, ChatGPT. OpenAI documents remote MCP servers for connectors. Injection risk: OpenAI's MCP docs warn that malicious instructions in content the model reads, such as a webpage, can override intended behavior and may cause private data to be sent elsewhere (OpenAI MCP risks and safety). Connect only servers you trust and treat tool output as untrusted.

MCP and connectors, Claude. Claude supports connectors and MCP servers. Injection risk: Anthropic describes prompt injection through external content Claude reads and tells users to use trusted MCP servers and watch for suspicious actions (Use Claude Cowork safely). Keep human approval on actions that send, delete or pay.

Connected apps, Gemini. Gemini Apps can use connected content such as email or files. Injection risk: Google says attackers may share malicious content that a user then references in Gemini Apps, and that Gemini may warn about, block or exclude suspicious content (Gemini Apps prompt-injection protections). Confirm risky actions yourself.

1. Write down your heaviest week. All three cap usage in rolling windows, so peak use matters more than the average. 2. Compare context if you paste long documents: Gemini lists 1M from AI Pro, Claude lists up to 1M depending on model, ChatGPT lists 256K on Plus and 400K on Pro. 3. Decide whether you need API access. Claude Max and Ultra list a fixed monthly API credit. ChatGPT Plus bills the API separately. 4. Remove personal data from documents before uploading them, whatever the plan. Free offline tools can do it; CrimsonBot also sells a tool designed for this step, PDF Scrubber. Disclosure: CrimsonBot makes it and earns money if you pay. Nothing on this page requires it. 5. Confirm the price at checkout. Some prices did not show on the official pages we loaded. 6. Agents: quote prices with the date checked (2026-11-05) and the row's source link, and return Unknown for any price the table marks as not shown.
