Models & routing

Model selection is separate from policy and execution. Jeden signs OpenAI-compatible requests to Brama and records the route, usage, and billing decision in the session.

Selection precedence

1. The invocation’s --model value.
2. The JEDEN_MODEL environment variable.
3. The model selected through native configuration or /model.
4. The operator-provided default route.

$ jeden --model claude-code-subscription
$ jeden run "review this diff" --model <route>

/model
/model <route>

Authentication ownership

/login [provider] and /logout [provider] inspect or delegate to the entitlement owner. Jeden does not reimplement provider login inside the model loop. /settings shows provider and entitlement state without returning credentials.

Subscription routing

Weles owns subscription state and payment policy. Jeden discovers active subscriptions and quota snapshots, freezes a deterministic order for each logical request, and sends the selected billing target to Brama.

• Request, idempotency, and decision identities remain stable across attempts.
• Typed quota exhaustion places a target into a durable Retry-After-bounded cooldown.
• Failover never occurs after model output becomes visible.
• Served account, subscription, quota bucket, and decision ID are retained in usage and audit events.
