Claude Code and other CLIs

Use supported command-line tools with a vendor account or with models available through ZeroLog.

Two ways to connect a CLIYou choose the connection mode first. With your own vendor account, Claude Code or Codex signs in inside a private workspace you own, the vendor bills you and the vendor's limits apply. With models on ZeroLog, you use ZeroLog chat or ZeroLog Code with a catalogue model, your ZeroLog credit pays per request and your account limits apply.Models on ZeroLogYour own vendor accountnative CLIcatalogue modelPick the connectionmode firstPrivate workspace you own.Claude Code: /login in the CLI.Codex: device sign-inVendor bills you.Vendor limits apply,unchangedRequest refused:follow the vendor's messageZeroLog chat orZeroLog Code.Pick a catalogue modelYour ZeroLog credit pays,per request.

  1. Pick the connection mode first.
  2. Your own vendor account: in a private workspace you own, sign in to Claude Code with /login inside the CLI, or to Codex with device sign-in.
  3. The vendor bills you, and the vendor's plan limits apply unchanged. If a request is refused, follow the vendor's message.
  4. Models on ZeroLog: use ZeroLog chat or ZeroLog Code and pick a model from the catalogue.
  5. Your ZeroLog credit pays per request and your account limits apply. If a request fails, pick another available model.

Available tools are Claude Code and Codex. Their sign-in and usage follow the mode you choose.

Native accounts and catalogue tools

Choose the connection mode first. Native Claude Code and Codex use vendor accounts; ZeroLog Code uses catalogue models.

Setup, billing and limits for each mode.
Your own vendor account Models on this service
How you set it Use the native Claude Code /login or Codex device sign-in in a private workspace. Use ZeroLog chat or ZeroLog Code and select a model from the catalogue.
Who bills you The vendor, under your subscription. Your ZeroLog credit, per request.
Which limits apply That vendor's plan limits, unchanged. This service does not raise them, extend them, or send a request past them. Your ZeroLog balance and account limits.
If a request fails The vendor's limits apply. If a request is refused, follow the vendor's message. If a request fails, choose another available model and try again.

Choose the account you want to use

Your vendor subscription and ZeroLog usage have separate billing and limits. A ZeroLog account limit does not change the limits set by your vendor.

Models on this service

Use a ZeroLog model

Choose a model from the catalogue. Requests count toward your ZeroLog usage and account limits.

Where usage appears

Your own vendor account

Your vendor tracks this usage under its account and subscription.

Models on this service

ZeroLog shows this usage with your other account activity. Your account limits apply.

The /goal continuation command belongs to ZeroLog chat; it is not automatically a native Claude Code or Codex command. See native sign-in and tool handover. A native login alone does not establish access to every vendor model. Settings, then AI accounts, shows whether each vendor account is connected and starts the Codex sign-in. Claude Code always signs in inside the CLI.
