Namespace AgentPrism · Assembly AgentPrism.OpenAI.dll

Builds the catalog shown in the user interface from the model definitions in the provider options.

public static class OpenAIModelCatalog

Remarks

AgentPrism carries no built-in model list. This is a deliberate decision: OpenAI model names and prices change much faster than a NuGet package is released. A list embedded in code becomes misleading in a short time.

Measured: an earlier built-in list contained none of the models a real account could reach; a call to gpt-4.1-mini from that list returned HTTP 403 model_not_found.

The catalog comes from the OpenAIProviderOptions.Models option. The catalog is not a validation list: a model name that is absent here can still be used, and the provider sends the request to OpenAI as it is. The catalog only feeds the model picker screen and the cost calculation of the user interface.
