Working with Prompts

// Create a versioned prompt
prompt, _ := provider.CreatePrompt(ctx, "chat-template",
    `You are a helpful assistant. User: {{.query}}`,
    llmops.WithPromptDescription("Main chat template"),
)

// Get a prompt
prompt, _ := provider.GetPrompt(ctx, "chat-template")

// Render with variables
rendered := prompt.Render(map[string]any{"query": "Hello!"})

Direct SDK Access

For Opik-specific features:
