Which models sit behind the paywall?

Both plans hand you a roster of models with different personalities and costs.

Claude models verified from docs.anthropic.com. All four carry a 1M-token context window, 128K max output tokens, and a knowledge cutoff near June 2026. A separate Mythos preview line exists with limited access.

03 - Limits & context

How fast do you run out?

Claude publishes dynamic limits; ChatGPT doesn't publish fixed caps at all.

Claude ProRolling + weekly, dynamic
Usage limitEvery 5 hours + weekly (1x baseline)
Context window1M tokens
Counter
A rolling limit every 5 hours and a weekly limit, at 1x baseline usage
What drains it
Model used, chat length, and file size - no fixed message count
Reset style
Dynamic and smooth, depends on what you ask and how long it is

Claude's limits are dynamic rather than a fixed number of messages. Long chats, big files, and heavier models draw the limit down faster.

Context window~54k / 256k everyday / reasoning (reported)
Counter
OpenAI does not publish fixed message caps for Plus
Reported context
About 54k tokens for everyday use and 256k for reasoning models - reported, not official
Daily chat
Everyday text chat is effectively unlimited subject to abuse limits
Heavy tasks
Reasoning or agent tasks reportedly use dynamic 5-hour allocations

ChatGPT Plus has no published usage caps. Everyday chat is broadly allowed, while heavy reasoning and agent work draw down dynamic allocations shown in your usage dashboard.

Exact limits and reset schedules change - verify against each vendor's current usage page before relying on numbers.
