12      result, _ := goai.GenerateText(
13          context.Background(),
14          openai.Chat("gpt-4o"),
15          goai.WithPrompt("Explain goroutines."),
16      )
17      fmt.Println(result.Text)
18  }

Works with

result, _ := goai.GenerateText(ctx,
    openai.Chat("gpt-4o"),
    goai.WithPrompt("Hello."),
)
fmt.Println(result.Text)

02StreamText

stream, _ := goai.StreamText(ctx,
    anthropic.Chat("claude-sonnet-4-6"),
    goai.WithMessages(msgs...),
)
for chunk := range stream.TextStream() {
    fmt.Print(chunk)
}

03GenerateObject[T]

type Recipe struct {
    Name   string   `json:"name"`
    Steps  []string `json:"steps"`
}
recipe, _ := goai.GenerateObject[Recipe](ctx,
    google.Chat("gemini-2.5-flash"),
    goai.WithPrompt("Pho recipe"),
)

04Tools & Agent Loop

calc := goai.Tool{
    Name:    "calc",
    Execute: evalMath,
}
result, _ := goai.GenerateText(ctx, model,
    goai.WithTools(calc),
    goai.WithMaxSteps(5), // auto loop
    goai.WithPrompt("127 * 43?"),
)

05TokenSource

// Auto-refresh OAuth tokens
ts := provider.CachedTokenSource(
    func(ctx) (*provider.Token, error) {
        tok, _ := oauth.Exchange(ctx, code)
        return &provider.Token{
            Value: tok.AccessToken,
            ExpiresAt: tok.Expiry,
        }, nil
    },
)
model := openai.Chat("gpt-4o",
    openai.WithTokenSource(ts),
)
