Quick answer
Claude Code documents max 20× prompt allowance as No prompt count is published; five-hour limits were doubled on 2026-05-06. Anthropic defines Max 20× as twenty times the Pro per-session allowance, shared across Claude and Claude Code, and no longer publishes a prompts-per-window estimate.

Why does this limit matter?
A larger allowance supports sustained agent work but still needs model and context budgeting.
This value is scoped to Max 20×; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Inspect /status and the selected model before calculating how many sessions remain.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- The earlier prompt ranges predate the May 2026 doubling of Claude Code five-hour limits and the removal of the peak-hours reduction; they are retained only as history.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
