Keep the client. Choose the route.
A Router key connects supported clients. Model availability depends on credentials, permissions, and protocol support.

Compare accounts by remaining weekly quotas, each quota’s reset date, and banked resets. Stale data stays clearly marked. API keys and personal subscriptions are separate access paths.

DeepSeek 4.1 Flash
Create a free Router account and check Billing for an available no-card DeepSeek trial: $1 of usage or 5M tokens, whichever comes first, once per verified email. The dollar limit usually applies first. Paid access through Modal Shared Endpoints or Fireworks requires a card. The 5M-token monthly Router quota and your usage cap are separate controls. Other Modal models are not included.
modal/deepseek-v4.1-flashThe paid route is metered at $0.30 / 1M input tokens, $0.03 / 1M cached input tokens, and $1.20 / 1M output tokens, up to your monthly usage cap. Access also depends on shared platform capacity and the serving endpoint being available; check your authenticated catalog before connecting a client.

Before your first request
Does a Router key include a model subscription?
No. A Router API key authenticates routed requests; provider credentials and Codex subscriptions remain separate. Platform-funded DeepSeek needs an available trial allowance or paid billing; other provider routes use your own credentials.
Can I use DeepSeek with Codex?
Yes. Use a model advertised by /v1/models?capability=codex_responses. The Modal route supports native Responses forwarding; the authenticated catalog is the authority for your available models. Follow the Codex setup guide.
How are requests funded?
Sign-up and Codex account monitoring are free. Check Billing for an available no-card DeepSeek trial and its remaining allowance. Paid DeepSeek is pay as you go, with no monthly base fee and a card on file. Your own provider keys are billed by your provider.
Will Router switch my local Codex account automatically?
No. You choose the account for a local Codex session. Router shows quotas and reset times so you can decide which account to use.
How do I get access?
Continue to ZergAI to check current account access. Existing users can sign in. Access and any billing requirements are confirmed in ZergAI, not inferred from this page.
