Allowances
Vendor publishes no figure
weekly limit, figure not published
›The vendor's own wording
"Local messages and cloud chats share your plan's usage allowance. Weekly limits may also apply." The page gives no weekly figure for any plan.Open the source page
Narrowed for specific models
These are not extra limits. Each one lowers the plan-wide allowance above for a single model, so the plan is worth what its best-covered model can spend, not this figure.

Subscription versus your own API key
This compares two ways of working the same way — in an IDE or CLI, where BYOK tools make a direct API key a real option. It is not a claim that subscriptions are cheaper than the API in general.

Usage terms
Quoted from the vendor's own terms. We do not give legal advice.
The Terms of Use, under "What you cannot do", state: "You may not use our Services for any illegal, harmful, or abusive activity. For example, you may not: ... Automatically or programmatically extract data or Output (defined below)." The same list also prohibits users from "circumvent any rate limits or restrictions or bypass any protective measures or safety mitigations we put on our Services". Note that the clause carries no carve-out for API access — the exemption is not in the wording, so the separation rests on billing rather than on the prohibition itself: OpenAI's pricing page attaches the Codex allowances above to the ChatGPT plan and offers API access as a separate option, "Pay for Codex usage based on API pricing".
