Use Unlimited Monthly when Codex CLI, Codex IDE, SDK, or agent usage repeats across the month. Both unlimitedcodex packages include unlimited token consumption with 4 concurrent connections and manual setup delivery.
Canonical facts

| Best check | Run /v1/models and one tiny endpoint request before a long coding-agent task. |
When Weekly is enough
Weekly fits uncertain work: testing whether a client, editor, SDK, or agent can use the delivered base URL, API key, and model IDs without committing to a month.
It also works for hackathons and demo weeks where the calendar is the real constraint and the team can plan around 4 concurrent connections.
When Monthly is better
Monthly fits repeat usage: ongoing Codex CLI work, app builds, agency projects, endpoint testing, and repeated agent loops across several weeks.
Choose Monthly only when the workflow has passed small endpoint checks and the 4-connection boundary is enough for expected parallel work.
Verification checklist
Choose Weekly when the workload may end within a few days.
Choose Monthly when the workflow repeats across more than one sprint.
Allow 10 minutes to 5 hours for manual delivery before the work window starts.
Cap active API calls at 4 concurrent connections.
Use the package picker if the timeline is unclear.
