Jean2 supports Anthropic, OpenAI, Google, MiniMax, OpenRouter, Z.AI, Z.AI Coding (Codex plan), and DeepSeek. Mix and match. Switch per session.

Add an API key

Location: Settings → Credentials

Click the gear icon (top-right) to open Settings. On mobile, tap the three-dots menu first.

Pick your provider, click Set, paste your API key, click Save. That's it. Models from that provider are now available in every session.

You can add keys for multiple providers. The agent doesn't care which one you use. Bring whatever you've got.

Connect via OAuth

Location: Settings → OAuth

Some providers support OAuth instead of API keys. Codex (ChatGPT Plus/Pro subscription) works this way. Click Connect, follow the link to log in, approve the connection. Done.

No API key needed. Tokens are stored server-side.

Use your models

Once a provider is connected, its models show up in the model selector at the bottom of every chat. Pick one. Start talking.

Models are organized by label (Budget, Standard, Premium) so you can use cheap models for routine work and reach for the expensive ones when it matters.

What's next

Models: customize context windows, capabilities, variants
Preconfigs: bundle a model + tools + prompt into an agent personality
Quick Start: your first conversation, end to end
