Bases: LLMAgent

Selects actions for AgentService based on a ReACT style LLM Prompt and a configured set of Tools.

NOTE: Deprecated. Use at your own risk.

WARNING: This model should only be used with LLMs that use the older model versions of gpt-4 (gpt-4-0314) and gpt-3.5-turbo (gpt-3.5-turbo-0301). Those models will be discontinued on 9-13-2023. Use of this agent after that date will likely lead to complete reasoning failures.
