# Enable a model

`POST /v1/workspaces/{workspaceId}/models/{id}:enable`

Transitions a model to STATE_ENABLED, making it available for agent variations in the workspace

## Path parameters

- `workspaceId` string, required
- `id` string, required

## Request body

- EnableModelRequest — Enable model request
  - `workspaceId` string — Workspace ID.
  - `id` string — Model ID

## Response `200`

OK

- Model
  - `metadata` ResourceMetadata, required — Standard metadata for persistent, named resources (e.g., agents, tools, prompts)
    - `id` string, required — Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...")
    - `accountId` string, required — Account this resource belongs to for multi-tenant isolation (prefixed ULID)
    - `workspaceId` string, required — Workspace this resource belongs to for organizational grouping (prefixed ULID)
    - `name` string, required — Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly
    - `externalId` string — External ID for the resource (e.g., a workflow ID from an external system)
    - `labels` object — Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"}
    - `profileId` string, required — ID of the actor (user or service account) that created this resource
    - `createdAt` string, date-time, required — Timestamp when this resource was created
    - `bundleKey` string — Optional bundle ownership key. When set, indicates the resource is managed by a configuration bundle identified by this key. Used by BulkWorkspaceResources.Apply to track which resources belong to which bundle for reconciliation / soft-delete on re-apply.
    - `updatedAt` string, date-time — Timestamp when this resource was last updated
  - `spec` ModelSpec, required
    - `provider` string — The model provider (e.g., "anthropic", "openai", "google")
    - `family` string — The model family (e.g., "claude-sonnet-4.6", "gpt-5.4", "gemini-2.5-flash")
    - `maxInputTokens` integer — Maximum number of input tokens the model supports
    - `maxOutputTokens` integer — Maximum number of output tokens the model can generate
    - `inputPricePerMillionTokens` string — Cost per million input tokens in cents (e.g., 300 = $3.00)
    - `outputPricePerMillionTokens` string — Cost per million output tokens in cents (e.g., 1500 = $15.00)
  - `info` ModelInfo — ModelInfo carries server-derived, read-only details about a model.
    - `provider` 'AI_PROVIDER_UNSPECIFIED' | 'AI_PROVIDER_OPENROUTER', enum — The AI provider this model routes through (via its provider key).
    - `aiProviderKey` ResourceMetadata — Standard metadata for persistent, named resources (e.g., agents, tools, prompts)
      - `id` string, required — Unique identifier for the resource (prefixed ULID, e.g., "agent_01HXK...")
      - `accountId` string, required — Account this resource belongs to for multi-tenant isolation (prefixed ULID)
      - `workspaceId` string, required — Workspace this resource belongs to for organizational grouping (prefixed ULID)
      - `name` string, required — Human-readable name for the resource (e.g., "Customer Support Agent", "Email Tool") Required for resources that users interact with directly
      - `externalId` string — External ID for the resource (e.g., a workflow ID from an external system)
      - `labels` object — Arbitrary key-value pairs for categorization and filtering Examples: {"environment": "production", "team": "platform", "version": "v2"}
      - `profileId` string, required — ID of the actor (user or service account) that created this resource
      - `createdAt` string, date-time, required — Timestamp when this resource was created
      - `bundleKey` string — Optional bundle ownership key. When set, indicates the resource is managed by a configuration bundle identified by this key. Used by BulkWorkspaceResources.Apply to track which resources belong to which bundle for reconciliation / soft-delete on re-apply.
      - `updatedAt` string, date-time — Timestamp when this resource was last updated
    - `agentVariationCount` integer — Number of agent variations currently provisioned on this model. Useful for previewing how many variations a swap would affect.
  - `state` 'STATE_UNSPECIFIED' | 'STATE_ENABLED' | 'STATE_DISABLED', enum, required — Whether the model is usable in this workspace. Output only. Use the :enable and :disable actions to transition.
