If you already pay for ChatGPT Plus, Claude Max, GitHub Copilot, or one of the other plans listed below, Manifest can route through the subscription instead of an API key. Auth is OAuth, a device code, or a pasted subscription token, depending on the provider.
Supported subscriptions
The Kimi Coding Plan serves k3, k3-256k, kimi-for-coding and
kimi-for-coding-highspeed. If a tier or a fallback still points at
kimi-k3, click Refresh models on the connection and pin one of these
ids instead.
Connect a subscription
Open the Subscriptions page
In the dashboard sidebar, open Providers → Subscriptions and click
Connect on the provider.
Complete the auth flow
Manifest opens the provider’s OAuth page, shows you a device code to enter,
or asks you to paste a token, depending on the provider. Once it’s saved,
you’re routed.

Standard OAuth against auth.openai.com. Once approved, requests route
through the Codex backend at chatgpt.com/backend-api/codex/responses
rather than the public OpenAI API. Tokens refresh automatically.
Generate a token with the Claude CLI (claude setup-token) and paste it into
Manifest. Requests carry the anthropic-beta: oauth-2025-04-20 header so
Anthropic recognizes the subscription token. Available models match what your
plan grants in claude.ai.
GitHub’s device-code flow. Manifest gives you a short user code, you visit
github.com/login/device, paste it, and
approve. No API key is ever issued. Requests then go to
api.githubcopilot.com/chat/completions using a short-lived token Manifest
refreshes for you. MiniMax’s device-code flow. Manifest gives you a short user code to approve,
then requests use the Anthropic protocol via api.minimax.io/anthropic
(international) or api.minimaxi.com/anthropic (China).
Paste the subscription token issued by Z.ai and pick a region in the
connect form. Requests route to api.z.ai (outside China, the default)
or open.bigmodel.cn (China Mainland).
Paste the subscription token from your OpenCode account. Requests use the
Anthropic protocol against opencode.ai/zen/go, authenticated via the
x-api-key header.
Subscription auth is rate-limited by the provider’s plan, not by Manifest. If
you hit a plan ceiling, requests fall through to your next
fallback model, usually a different provider on an API key. Why mix subscriptions and API keys
A common setup: subscription as the primary (predictable monthly cost), API-key provider as the fallback for when you hit the plan limit or want a model the subscription doesn’t include.
Pin your subscription model to your default or a custom tier and add API-key models to the fallback list. Manifest handles the switch.
