But basically you get ~300Mn input tokens and ~100Mn output tokens per month with Sonnet on the $100 plan. These are split across 50 sessions you are allowed, each session is 5 hrs starting from the first time you send a message until 5 hrs after the first message. During this time, you get ~6Mn input and ~2Mn output tokens for Sonnet. Claude Code seems to use a mix of Sonnet and Haiku, and Haiku has 2x the limits of Sonnet.

So if you absolutely maxed out your 50 sessions every month, that's $2400 worth of usage if you instead had used the API. So it's a great deal. It's not $100 worth of API credits you're buying, so they don't run out like that. You can exhaust limits for a given session, which is at most a 5 hr wait for your next one, or you can run out of 50 sessions, I don't know how strongly they enforce that limit and I think that limit is BS, but all in all the value for money is great, way better than using the API.

How Rate Limits Work: With the Max plan, your usage limits are shared across both Claude and Claude Code:

Shared rate limits: All activity in both Claude and Claude Code counts against the same usage limits.

Message variations: The number of messages you can send on Claude varies based on message length, conversation length, and file attachments.

Coding usage variations: Expected usage for Claude Code will vary based on project complexity, codebase size, and auto-accept settings.

On the Max plan (5x Pro/$100), average users:

- Send approximately 225 messages with Claude every 5 hours, OR

- Send approximately 50-200 prompts with Claude Code every 5 hours

On the Max plan (20x Pro/$200), average users:

- Send approximately 900 messages with Claude every 5 hours, OR

- Send approximately 200-800 prompts with Claude Code every 5 hours
