var ErrUnsupportedProvider = fmt.Errorf("init_chat_model: unsupported provider")

ErrUnsupportedProvider is returned when the provider id has no registered factory.

Functions ¶

func InitChatModel ¶

func InitChatModel(ctx context.Context, providerModel string) (llms.Model, error)

InitChatModel resolves a "provider:model" string to a chat model, e.g. "openai:gpt-5" or "anthropic:claude-opus-5". If no provider prefix is present, it defaults to "openai".

func Register ¶

func Register(provider string, f Factory)

Register registers a factory for a provider id (e.g. "openai", "anthropic").

Types ¶

type Factory ¶

type Factory func(ctx context.Context, model string) (llms.Model, error)

Factory builds a chat model. It receives the model name and returns a Model.

func Lookup ¶

func Lookup(provider string) (Factory, bool)

Lookup returns the factory for a provider, if registered.
