Types

type Model

type Model struct {
	// contains filtered or unexported fields
}

Model adapts langchaingo llms.Model to intent.LLM.

func MustNewOpenAI

func MustNewOpenAI(opts ...OpenAIOption) *Model

MustNewOpenAI is like NewOpenAI but panics on error.

func NewModel

func NewModel(model lclang.Model, info intent.Model) *Model

NewModel wraps a langchaingo model.

func NewOpenAI

func NewOpenAI(opts ...OpenAIOption) (*Model, error)

NewOpenAI returns an intent.LLM backed by OpenAI via langchaingo. Unset fields are populated from OPENAI_MODEL, OPENAI_API_KEY, and OPENAI_BASE_URL when present.

func (*Model) Generate

func (m *Model) Generate(ctx context.Context, req intent.Request) (intent.Response, error)

func (*Model) Model

func (m *Model) Model() intent.Model

func (*Model) Stream

func (m *Model) Stream(ctx context.Context, req intent.Request) (intent.Stream, error)

type OpenAIOption

type OpenAIOption func(*openaiConfig)

OpenAIOption configures an OpenAI-backed intent.LLM.

func WithOpenAIAPIKey

func WithOpenAIAPIKey(key string) OpenAIOption

WithOpenAIAPIKey sets the OpenAI API key.

func WithOpenAIBaseURL

func WithOpenAIBaseURL(baseURL string) OpenAIOption

WithOpenAIBaseURL sets a custom OpenAI-compatible base URL.

func WithOpenAIInfo

func WithOpenAIInfo(info intent.Model) OpenAIOption

WithOpenAIInfo sets model metadata exposed through intent.Model.

func WithOpenAIModel

func WithOpenAIModel(name string) OpenAIOption

WithOpenAIModel sets the OpenAI model name.
