call

call(values, config?): Promise<ChainValues>
Run the core logic of this chain and add to output if desired.

Wraps _call and handles memory.
Parameters
- values: any
- Optionalconfig: any
Returns Promise<ChainValues>
Inherited from LLMChain.call
- Defined in langchain/src/chains/llm_chain.ts:180

invoke

invoke(input, options?): Promise<ChainValues>
Invoke the chain with the provided input and returns the output.
Parameters
- input: ChainValues
  Input values for the chain run.
- Optionaloptions: any
Returns Promise<ChainValues>
Promise that resolves with the output of the chain run.
Inherited from LLMChain.invoke
- Defined in langchain/src/chains/base.ts:86

predict

predict(values, callbackManager?): Promise<string>
Format prompt with values and pass to LLM
Parameters
- values: any
  keys to pass to prompt template
- OptionalcallbackManager: any
  CallbackManager to use
Returns Promise<string>
Completion from LLM.
Example
```
llm.predict({ adjective: "funny" })

`Static`deserialize

deserialize(data): Promise<LLMChain<string, any>>
Load a chain from a json-like object describing it.
Parameters
- data: SerializedLLMChain
Returns Promise<LLMChain<string, any>>

- Defined in langchain/src/chains/llm_chain.ts:258

`Static`fromLLM

fromLLM(fields): LLMChain<string, any>
Static method to create a new TaskPrioritizationChain from a BaseLanguageModel. It generates a prompt using the PromptTemplate class and the task prioritization template, and returns a new instance of TaskPrioritizationChain.
Parameters
- fields: Omit<LLMChainInput<string, any>, "prompt">
  Object with fields used to initialize the chain, excluding the prompt.
Returns LLMChain<string, any>
A new instance of TaskPrioritizationChain.
