Only resell models can be assigned; included models are already available to all projects. Assigning needs the model to be enabled by an org admin and not disabled. Unassigning is always allowed. Unassigning stops flows of the project that use the model from running. ## OpenAPI ````yaml https://api-trial.cognigy.ai/openapi/openapi-viewer.json patch /v2.0/inplatform/largelanguagemodels/{largeLanguageModelId}/assigned openapi: 3.0.0 info: title: Cognigy.AI REST-ful-API Reference version: 2026.23.0 description: > ### Introduction This is the [OpenAPI 3.0](https://swagger.io/specification/) documentation of the [REST](https://en.wikipedia.org/wiki/Representational_state_transfer)-ful Cognigy.AI API. ### Cross-Origin Resource Sharing This API features Cross-Origin Resource Sharing (CORS) implemented in compliance with [W3C spec](https://www.w3.org/TR/cors/), which allows cross-domain communication from the browser. All responses include a wildcard same-origin header, making the API fully accessible. ### Authentication Cognigy.AI offers three forms of authentication: - API Key - CXone Token - BasicAuth An API Key is a security token. You can use API Keys in your path or HTTP header. Never expose your API Key and keep it safe and secure. Revoke the API Key if it got exposed or stolen. Basic Auth is only used for API calls regarding the Management-UI. ### Error Handling This API uses HTTP status codes equal or above 400 to indicate errors. Error details are generated in compliance with [RFC 7807 - "Problem Details for HTTP APIs"](https://tools.ietf.org/html/rfc7807). Every error response contains a traceId, which should be provided to the Cognigy.AI Technical Support when reporting an error. contact: name: Cognigy Technical Support url: https://www.cognigy.com email: support@cognigy.com servers: - url: https://api-trial.cognigy.ai/new/ description: Cognigy.AI API security: - APIKeyHeader: [] - APIKeyQueryParam: [] - CXoneTokenHeader: [] - BasicAuth: [] tags: - name: Cognigy.AI REST-ful API description: The Cognigy.AI REST-ful API externalDocs: description: Cognigy.AI Documentation url: https://docs.cognigy.com/docs/ paths: /v2.0/inplatform/largelanguagemodels/{largeLanguageModelId}/assigned: patch: tags: - In-Platform LLMs summary: Assign or unassign a resell In-Platform LLM to or from a project description: >- Makes a resell in-platform LLM available to a project (`assigned` set to `true`) or removes it from the project (`assigned` set to `false`) by updating the LLM's `assignedToProjects`.
