A name or an alias such as router@candidate is refused, since a retry could find another version behind it. Its record stays, and GET /v1/models/router lists it as retired. Its files are deleted after the days in limits.retired_days of GET /v1/decisionone, or sooner: when retiring leaves the account's retired versions' files taking more than its storage allowance, the oldest go then, apart from any retired in the last few minutes. Never while a fine-tune trains from it. A version in production is refused: take it out of production first. Retiring again changes nothing. ## OpenAPI ````yaml /openapi.json post /v1/models/{model_id}/retire openapi: 3.1.0 info: title: DecisionOne workbench description: >- Native decisions, immutable datasets, adaptation and shared-base deployment. Authenticate with `Authorization: Bearer d1_sk_...` when accounts are on. A short guide for coding agents is at /llms.txt. Hosted account APIs accept a Bearer API key or a browser session. An API key reads its account but can't change it: keys, billing and settings change in the console. Browser mutations require the configured Origin and X-CSRF-Token from /auth/session. Account recovery and history remain available to blocked accounts. Waitlisted accounts can read their account summary and model catalogue and request early access; private member APIs require admission. Money fields ending in _usd are exact decimal strings; never interpret them as integer cents. Authenticated customer reads and existing-operation replays share read_rpm, and other customer writes except decisions and estimates share write_rpm. Feedback has the tier's rpm to itself. Exhausted budgets return 429 with Retry-After; unavailable admission storage returns 503. version: 0.1.0 servers: - url: https://console.sqwish.ai security: [] tags: - name: Decisions description: Probabilities for questions with fixed outcomes. - name: Feedback description: Report outcomes and turn them into training data. - name: Models description: Base models, adapters and named models with versions. - name: Datasets description: Validated training examples.
