Providers — 108 Integrations

Beluga AI v2 ships with 108 provider implementations across 15 categories. Every provider follows the same registry pattern: import the package, and it auto-registers via init(). Switch between providers by changing an import path and configuration — no code changes required.

Each provider page documents configuration options, code examples, and guidance on when to choose that provider. All examples use the github.com/lookatitude/beluga-ai module path and handle errors explicitly.

Registry Pattern

Every provider category uses the same pattern:

import (
    "github.com/lookatitude/beluga-ai/llm"
    _ "github.com/lookatitude/beluga-ai/llm/providers/openai"     // auto-registers
    _ "github.com/lookatitude/beluga-ai/llm/providers/anthropic"  // auto-registers
)

// Create by name
model, err := llm.New("openai", cfg)

// Discover available providers
names := llm.List() // ["anthropic", "openai", ...]

Adding Custom Providers

Any provider category can be extended by implementing the interface and calling Register() in init():

func init() {
    llm.Register("my-provider", func(cfg config.ProviderConfig) (llm.ChatModel, error) {
        return &myModel{apiKey: cfg.APIKey}, nil
    })
}

See the API Reference for complete interface definitions, or browse individual provider pages for configuration details and usage examples.
