Pi

Pi includes Rewyyn providers for pay-as-you-go and Go. It picks the right API for each paid or Go model. Free-tier chat models require Rewyyn and return HTTP 403 from Pi.

Configure

Both providers read the key from REWYYN_API_KEY. Create a personal API key.

export REWYYN_API_KEY="oc_sk_..."
pi --model rewyyn/claude-sonnet-5-5

You can also run /login in Pi and select the provider. Pi stores the key in ~/.pi/agent/auth.json.

/login rewyyn

Go

Use the rewyyn-go provider with a key from a workspace with a Go subscription.

pi --model rewyyn-go/kimi-k3

Models

Select a model as <provider>/<model-id>, using IDs from the Console or Go table. List the models Pi knows about with --list-models.

pi --list-models rewyyn-go

Set a default in ~/.pi/agent/settings.json, or press Ctrl+S in the /model picker.

{
  "defaultProvider": "rewyyn-go",
  "defaultModel": "kimi-k3"
}

Run pi update --models when a new Console model doesn’t appear yet.

Console MCP

Pi v0.99.0 and later support MCP. Add the Console MCP server, then sign in from the browser.

pi mcp add rewyyn-console --url https://rewyyn.org/console/mcp
pi mcp login rewyyn-console
