# OpenAI Model for ADK-Go This package provides an OpenAI model implementation for the [ADK-Go](https://github.com/google/adk-go) framework. ## Usage `go get github.com/byebyebruce/adk-go-openai` ```go package main import ( "context" "fmt" "log" "os" openai "github.com/byebyebruce/adk-go-openai" go_openai "github.com/sashabaranov/go-openai" "google.golang.org/adk/agent" "google.golang.org/adk/agent/llmagent" "google.golang.org/adk/cmd/launcher" "google.golang.org/adk/cmd/launcher/full" "google.golang.org/adk/tool" "google.golang.org/adk/tool/functiontool" ) type Input struct { City string `json:"city" jsonschema:"city name"` } type Output struct { WeatherSummary string `json:"weather_summary" jsonschema:"weather summary in the given city"` } func GetWeather(ctx tool.Context, input Input) (Output, error) { log.Println("Getting weather for city: ", input.City) return Output{ WeatherSummary: fmt.Sprintf("Today in %q is sunny\n", input.City), }, nil } func main() { ctx := context.Background() modelName := "gpt-5.1" openaiCfg := go_openai.DefaultConfig(os.Getenv("OPENAI_API_KEY")) if baseURL := os.Getenv("OPENAI_BASE_URL"); baseURL != "" { openaiCfg.BaseURL = baseURL } weatherTool, err := functiontool.New(functiontool.Config{ Name: "weather", Description: "Returns weather in a city", }, GetWeather) if err != nil { log.Fatalf("Failed to create tool: %v", err) } model := openai.NewOpenAIModel(modelName, openaiCfg) a, err := llmagent.New(llmagent.Config{ Name: "weather_agent", Model: model, Description: "Agent to answer questions about weather in a city.", Instruction: "Your SOLE purpose is to answer questions about the current weather in a specific city. You MUST refuse to answer any questions unrelated to weather.", Tools: []tool.Tool{ weatherTool, }, }) if err != nil { log.Fatalf("Failed to create agent: %v", err) } config := &launcher.Config{ AgentLoader: agent.NewSingleLoader(a), } l := full.NewLauncher() if err = l.Execute(ctx, config, os.Args[1:]); err != nil { log.Fatalf("Run failed: %v\n\n%s", err, l.CommandLineSyntax()) } } ``` ## For Ollama `export OPENAI_BASE_URL='http://localhost:11434/v1/'` ## Example [Example](example)
