Functions ¶

func Cosine ¶

func Cosine(a, b []float32) float32

Cosine returns the cosine similarity between two vectors.

Types ¶

type Provider ¶

type Provider interface {
	Embed(ctx context.Context, text string) ([]float32, error)
	Dims() int
	Name() string
}

Provider generates vector embeddings for text.

func NewLocal ¶

func NewLocal() Provider

NewLocal returns a local stub provider that generates deterministic pseudo-vectors from SHA-256 hashes. Useful for testing and offline use. NOT semantically meaningful — use OpenAI/Voyage for real semantic search.

func NewOpenAI ¶

func NewOpenAI(apiKey, model string) Provider

NewOpenAI creates an OpenAI embedding provider. model: "text-embedding-3-small" (1536 dims) or "text-embedding-3-large" (3072 dims)

func NewVoyage ¶

func NewVoyage(apiKey, model string) Provider

NewVoyage creates a Voyage AI embedding provider. model: "voyage-code-3" (optimized for code)
