Models & Subscriptions

Kimaki gives you access to every model OpenCode supports: Anthropic, OpenAI, Google, and more. You can authenticate with an API key, or use your existing Claude Pro/Max and ChatGPT/Codex subscriptions via OAuth so you pay nothing extra per token.

The /login command

Run /login in any project channel. Kimaki walks you through a short flow:
  /login
    │
    ▼
  ┌──────────┐      ┌──────────┐      ┌──────────┐
  │ provider │ ───▶ │  method  │ ───▶ │   auth   │
  │ (anth/   │      │ (OAuth/  │      │ (modal)  │
  │  openai) │      │  key)    │      │          │
  └──────────┘      └──────────┘      └──────────┘
  1. Pick a provider. Connected providers show a checkmark.
  2. Pick a method. Choose OAuth to use a subscription, or API key to paste a key.
  3. Authenticate. For OAuth, open the link and authorize; some providers ask you to paste a short code back. For API keys, enter the key in a modal.

Using subscriptions instead of API credits

The reason to choose OAuth is cost. When you log in with OAuth, Kimaki authenticates the same way the native CLIs do, so your subscription covers inference and per-token costs show as zero.
  • Anthropic — log in with your Claude Pro or Claude Max subscription. Kimaki requests the inference scope and treats requests as Claude Code requests, so subscription usage applies.
  • OpenAI / Codex — log in with your ChatGPT subscription to use Codex models without per-token API billing.
If you already authenticated OpenCode on this machine (for example with the OpenCode CLI), those credentials are reused. You may not need to /login at all.

Multiple accounts and rotation

You can store more than one OAuth account per provider. When a run hits a rate limit or auth failure, Kimaki automatically rotates to the next account so your work keeps going.
Manage the account pool from the CLI:
# List all stored Anthropic + OpenAI accounts (active one marked)
kimaki multioauth list

# Per-provider management
kimaki multioauth anthropic list
kimaki multioauth anthropic remove <index-or-email>

kimaki multioauth openai list
kimaki multioauth openai check     # test all accounts for usage limits
kimaki multioauth openai remove <index-or-email>

Choosing the model after login

Once a provider is connected, pick the model:
  • /model — choose provider, model, and (if supported) a thinking-level variant. Store it per session, per channel, or globally.
  • Agent files — define a model + variant + permissions once and switch with a single /<name>-agent command. This is faster than the /model menus when you switch often.
See Model & Agent Switching for the full agent-file workflow.

API keys instead of subscriptions

Prefer a plain API key? Choose API key in the /login method step and paste it. You can also set the model directly in your project's opencode.json:
{
  "model": "anthropic/claude-sonnet-4-20250514"
}
Format is provider/model-name, for example openai/gpt-5.3-codex or google/gemini-3-pro-preview.
