Switch model tiers
How the fast/standard/premium model picker works and what decides which one you can use.
Every chat message is sent to one of three model tiers, chosen from the model picker in the composer:
- fast — lowest cost, lowest latency. Available on every plan, including Free.
- standard — a stronger general-purpose model.
- premium — the strongest available model, for the hardest tasks.
What decides which tiers you can use
Your plan decides which model tiers you're allowed to call — this is checked on the server for every request, not just hidden in the UI. If a tier isn't included in your plan, the picker won't let you send with it.
What's not here yet
An Auto mode that picks a tier for you based on the request is planned but not implemented — today you always pick the tier yourself.
Cost
Every message's exact prompt/completion token count and USD cost is recorded and debited from your organization's ledger balance in the same transaction as the reply — see How it works for the full request lifecycle, and Check your quota and add credit for how to see your remaining daily quota.
