Methods

apply

apply(inputs, config?): Promise<ChainValues[]>
Parameters
- inputs: ChainValues[]
- Optionalconfig: any[]
Returns Promise<ChainValues[]>
Deprecated
Use .batch() instead. Will be removed in 0.2.0.

Call the chain on all inputs in the list
Inherited from LLMChain.apply
- Defined in langchain/src/chains/base.ts:258

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" })
```

prepOutputs

prepOutputs(inputs, outputs, returnOnlyOutputs?): Promise<Record<string, unknown>>
Parameters
- inputs: Record<string, unknown>
- outputs: Record<string, unknown>
- returnOnlyOutputs: boolean = false

run

run(input, config?): Promise<string>
Parameters
- input: any
- Optionalconfig: any
Returns Promise<string>
Deprecated
Use .invoke() instead. Will be removed in 0.2.0.
Inherited from LLMChain.run
- Defined in langchain/src/chains/base.ts:190

serialize

serialize(): SerializedLLMChain
Returns SerializedLLMChain
Deprecated
Inherited from LLMChain.serialize
- Defined in langchain/src/chains/llm_chain.ts:274

`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>>
Inherited from LLMChain.deserialize
- Defined in langchain/src/chains/llm_chain.ts:258

`Static`fromLLM

fromLLM(fields): LLMChain<string, any>
A static factory method that creates an instance of TaskExecutionChain. It constructs a prompt template for task execution, which is then used to create a new instance of TaskExecutionChain. The prompt template instructs an AI to perform a task based on a given objective, taking into account previously completed tasks.
Parameters
- fields: Omit<LLMChainInput<string, any>, "prompt">
  An object of type LLMChainInput, excluding the "prompt" field.
Returns LLMChain<string, any>
An instance of LLMChain.
