🦜️🔗 LangChain Go
⚡ Building applications with LLMs through composability ⚡
🤔 What is this?
This is the Go language implementation of LangChain.
📖 Documentation
🎉 Examples
See ./examples for example usage.
package main
import (
"context"
"log"
"gitee.com/zzcadmin/langchaingo/llms/openai"
)
func main() {
llm, err := openai.New()
if err != nil {
log.Fatal(err)
}
prompt := "What would be a good company name for a company that makes colorful socks?"
completion, err := llm.Call(context.Background(), prompt)
if err != nil {
log.Fatal(err)
}
log.Println(completion)
}
$ go run .
Socktastic!
