Class BabyAGI

Class responsible for managing tasks, including their creation, prioritization, and execution. It uses three chains for these operations: creationChain, prioritizationChain, and executionChain.

Example

const babyAGI = BabyAGI.fromLLM({
  llm: new OpenAI({ temperature: 0 }),
  vectorstore: new MemoryVectorStore(new OpenAIEmbeddings()),
  maxIterations: 3,
});

const result = await babyAGI.call({
  objective: "Write a weather report for SF today",
});
