Claude Code usage limits: what the messages mean, and how to keep working

What Claude Code's session, weekly, Opus and Sonnet limit messages mean, what Anthropic suggests, and how to carry the task on with another agent in Mirasim.

Mirasim's agent and model picker open in a session, where you can switch to another agent and keep the conversationMirasim's agent and model picker open in a session, where you can switch to another agent and keep the conversation

The short answer

Claude subscription plans include a rolling usage allowance. When it runs out, Claude Code stops sending requests until the reset time in the message. The session and weekly limits cover every model, so switching models doesn't help; the Opus and Sonnet limits cover only that model family, so /model to another family keeps you going.

MessageWhat it coversSwitching models helps?
You've hit your session limit · resets …All models, rolling session windowNo
You've hit your weekly limit · resets …All models, weekly allowanceNo
You've hit your Opus limit · resets …Opus models onlyYes, to a non-Opus model
You've hit your Sonnet limit · resets …Sonnet models onlyYes, to a non-Sonnet model

Usage counts against the session and weekly allowances at the same time, so one heavy burst can use up the week before the session window resets.

What Anthropic suggests

  • Wait for the reset time in the message. In the CLI, “Continue automatically at usage limit” in /config picks the task up after the reset; in the desktop app, the session-limit card has “Auto-continue when limits reset” (the weekly-limit card doesn't).
  • Run /usage to see your plan limits and when they reset.
  • For the Opus or Sonnet limit, run /model and pick a model from another family. The next request re-reads the whole conversation without cache hits.
  • Run /usage-credits to buy additional usage on Pro, Max and Ultra, or to request it from your admin on Team and Enterprise.
  • For higher base limits, upgrade your plan at claude.com/pricing.

Keep the task going in Mirasim

  1. Claude Code hits a limit

    The message shows when it resets

  2. Switch the agent in the same pane

    Codex, Kimi Code, DeepSeek Harness or another agent

  3. The conversation comes along

    Same pane, same transcript; the new agent picks up from there

  • Switching agents carries the conversation over, so the task doesn't start from scratch.
  • Or stay on Claude Code and pick a model under Built-in, which runs on Mirasim credit rather than your Claude plan.
  • Each saved account shows its live quota: the plan, how much of each current window is used, and when it resets. Open the account card at the bottom left › Usage.

Questions

Does switching models reset the limit?
Not for the session or weekly limit, which cover every model. For the Opus or Sonnet limit, a model from another family keeps you working.
How do I see how much I have left?
Run /usage in Claude Code, add the rate_limits fields to a custom status line, or click the usage ring in the Claude desktop app. In Mirasim, the Usage panel shows each account's windows and reset times.
Can I buy more usage?
On Pro, Max and Ultra, /usage-credits buys additional usage; on Team and Enterprise it asks your admin. See Anthropic's support article on usage credits for how it's billed.
Does Mirasim raise my Claude limits?
No. Your Claude plan's limits are Anthropic's. Mirasim lets the same session carry on with another agent, or with a built-in model on Mirasim credit.
