Use your subscription
Without a subscription, model usage is paid from your Ellipsis credits. To use your own Claude or ChatGPT plan instead:
- Open Models > Subscriptions and choose Add subscription.
- Pick the provider and paste its credential:
- Claude: the token printed by
claude setup-token. API keys aren't accepted. - Codex: the contents of
~/.codex/auth.jsonafter runningcodex -c cli_auth_credentials_store="file" loginand signing in with ChatGPT. Treat this file as a password.
- Claude: the token printed by
- Choose Save & verify.
A Claude subscription pays for Claude models, and a Codex subscription pays for GPT models. GLM-5.2 and MiniMax M3 always use credits. A subscription belongs to the person who added it; see Pricing for which sessions it covers. A session uses credits if, when it starts, your subscription isn't verified or your Codex login can't be refreshed. After a session starts, a failed subscription request fails the session instead of switching to credits.
