ChatEvaluate

ChatEvaluate[chat,text]

appends text and its follow-up to the ChatObject chat.

ChatEvaluate[text]

represents an operator form of ChatEvaluate that can be applied to a ChatObject.

Details and Options

  • ChatEvaluate is used to continue the conversation in a ChatObject.
  • ChatEvaluate requires external service authentication, billing and internet connectivity.
  • The following options can be specified:
  • Authentication Inheritedexplicit user ID and API key
    LLMEvaluator InheritedLLM configuration to use
    ProgressReporting$ProgressReportinghow to report the progress of the computation
  • If LLMEvaluator is set to Inherited, the LLM configuration specified when the chat was created is used, and no additional prompts are appended.
  • If LLMEvaluator is not set to Inherited, any prompts specified by the option may be added.
  • LLMEvaluator can be set to an LLMConfiguration object or an association with any of the following keys:
  • "MaxTokens"maximum amount of tokens to generate
    "Model"base model
    "PromptDelimiter"string to insert between prompts
    "Prompts"initial prompts
    "StopTokens"tokens on which to stop generation
    "Temperature"sampling temperature
    "ToolMethod"method to use for tool calling
    "Tools"list of LLMTool objects to make available
    "TopProbabilities"sampling classes cutoff
    "TotalProbabilityCutoff"sampling probability cutoff (nucleus sampling)
  • Valid forms of "Model" include:
  • namenamed model
    {service,name}named model from service
    <|"Service"service,"Name"name|>fully specified model
  • The generated text is sampled from a distribution. Details of the sampling can be specified using the following properties of the LLMEvaluator:
  • "Temperature"tAutomaticsample using a positive temperature t
    "TopProbabilities"kAutomaticsample only among the k highest-probability classes
    "TotalProbabilityCutoff"pAutomaticsample among the most probable choices with an accumulated probability of at least p (nucleus sampling)
  • The Automatic value of these parameters uses the default for the specified "Model".
  • Multiple prompts are separated by the "PromptDelimiter" property of the LLMEvaluator.
  • Possible values for Authentication are:
  • Automaticchoose the authentication scheme automatically
    Inheritedinherit settings from chat
    Environmentcheck for a key in the environment variables
    SystemCredentialcheck for a key in the system keychain
    ServiceObject[]inherit the authentication from a service object
    assocprovide explicit key and user ID
  • With AuthenticationAutomatic, the function checks the variable "OPENAI_API_KEY" in Environment and SystemCredential; otherwise, it uses ServiceConnect["OpenAI"].
  • When using Authenticationassoc, assoc can contain the following keys:
  • "ID"user identity
    "APIKey"API key used to authenticate
  • ChatEvaluate uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.

Basic Examples  (1)

Create a new chat:

Add a message and a response to the conversation:

Scope  (3)

Start a new conversation:

Continue an existing conversation:

Use the function as an operator:

Options  (10)

Authentication  (4)

Provide an authentication key for the API:

Look for the key in the system keychain:

Specify the name of the key:

Look for the key in the system environment:

Authenticate via a service object:

LLMEvaluator  (6)

Specify the service used to generate the answer:

Specify both the service and the model:

By default, the text generation continues until a termination token is generated:

Limit the amount of generated samples (tokens):

Specify that the sampling should be performed at zero temperature:

Specify a high temperature to get more variation in the generation:

Specify the maximum cumulative probability before cutting off the distribution:

Specify the service and the model to use for the generation:

Specify a prompt to be automatically inserted:

Possible Issues  (1)

Evaluating a chat session with a specific service embeds the authentication information:

With the default setting AuthenticationInherited, the authentication will not work on a different service:

Use Authentication->Automatic or provide explicit authentication for the new service to reconnect:
