Provider Property

Sets or returns the identifier for the current service provider.

Syntax

object.Provider [= value ]

Remarks

The Provider property returns a numeric identifier for the current provider. If no provider has been selected, this property returns zero. Changing this property selects the provider used for inference. This is used with the ModelName property to specify the service and model the client will use. This property cannot be changed while there is an active connection to a service provider.

Constant Value Description

llmProviderNone 0 No provider specified.

llmProviderLocal 1 Local inference provider, such as LM Studio or Ollama.

llmProviderOpenAI 2 OpenAI provider using the ChatGPT models.

llmProviderAnthropic 3 Anthropic provider using the Claude models.

llmProviderGoogle 4 Google AI provider using the Gemini models.

llmProviderMicrosoft 5 Microsoft Azure AI Foundry provider using OpenAI-compatible models.

llmProviderMistral 6 Mistral AI provider using the Mistral models.

The provider identifiers are predefined values used by the control to select an internal provider definition. In some cases, applications may be able to use a compatible provider by selecting the provider whose API format it supports, and then setting the BaseUrl and ModelName properties to the appropriate values. For example, a provider which implements an OpenAI-compatible API may be used by selecting llmProviderOpenAI and specifying the provider's endpoint and model name.

The Provider and ProviderName properties are reciprocal. Changing the value of one property automatically changes the value of the other.

Changing the current provider also resets the ModelName and ModelFlags properties to the default model for the selected provider, and resets the BaseUrl property to the default endpoint for that provider. Applications should always set the provider identifier first, and then change the model name or endpoint URL if necessary.

Setting this property to llmProviderNone clears the values of the BaseUrl, ModelName and ModelFlags properties.

    If LlmClient1.SendMessage() Then

    Else
        MsgBox LlmClient1.LastErrorString, vbExclamation
    End If
