Aliases
Call a name like "fast" or "smart" instead of a model ID, and repoint it here without a deploy. Its fallbacks are tried in order when the model fails. A project's own alias overrides the one for every project.
| ALIAS | APPLIES TO | CALLS | THEN | UPDATED | |
|---|---|---|---|---|---|
fast | Every project | anthropic/claude-haiku-5-5 | openai/gpt-6-luna | 6/10/2026 | |
smart | Every project | anthropic/claude-sonnet-5-5 | openai/gpt-6.1-sol | 21/10/2026 | |
draft | MailSimp | anthropic/claude-haiku-5-5 | — | 28/10/2026 |
Save the same alias and scope again to repoint it. Replies to an alias carry x-oneway-alias, and x-oneway-model names the model that answered.
Calling a model
The same key works for every model; switching is a one-word change.
