Choose by bottleneck
The limits, not the vibes, are the real difference at $20/month.
Choose Plus for message volume and breadth
160 messages / 3 hours, up to 3,000 reasoning messages / week, images and files included. Hitting a cap downgrades the model instead of blocking you.
Choose Claude Pro for long documents and Claude Code
~45 messages / 5 hours but a 200K-token context window (6× Plus). Includes Claude Code in the same usage windows. Hard stop when the window is spent.

What the limits mean in practice
How the tracked numbers above play out in real workflows.
Message limits: 3× more volume on Plus
ChatGPT Plus allows 160 flagship-model messages per 3 hours; Claude Pro allows about 45 per 5 hours, and long attachments burn it faster. If you chat all day, Plus's caps are much harder to hit.
Context: 6× more depth on Claude Pro
Claude Pro reads about 200K tokens of context versus roughly 32K on Plus in the ChatGPT interface. For briefs, codebases, and long manuscripts, Claude holds the whole document where ChatGPT cannot.
Failure mode matters
When you hit the cap, ChatGPT falls back to a lighter model and keeps working; Claude stops until the 5-hour window resets. Deadline workers should weigh that hard stop seriously.
