Functions

func GetAllModels added in v0.2.0 

func GetAllModels() map[ModelID]Model

GetAllModels returns both static and dynamic models

func IsCopilotAnthropicModel added in v0.3.0 

func IsCopilotAnthropicModel(apiModel string) bool

IsCopilotAnthropicModel returns true if the given API model name is an Anthropic model served through the GitHub Copilot API (detected by name containing "claude").

func LoadModelCache added in v0.3.0 

func LoadModelCache() error

LoadModelCache loads previously cached dynamic models into SupportedModels. Cached models do not overwrite static entries (Azure, VertexAI, Bedrock).

func RefreshProviderModels added in v0.2.0 

func RefreshProviderModels(ctx context.Context, provider ModelProvider, apiKey string, bearerToken string, baseURL string) error

RefreshProviderModels fetches and registers models from a provider

func RegisterDynamicModel added in v0.2.0 

func RegisterDynamicModel(model Model)

RegisterDynamicModel adds a dynamically discovered model

func ResolveOllamaBaseURL added in v0.2.0 

func ResolveOllamaBaseURL(configured string) string

func ResolveOllamaRawBaseURL added in v0.2.0 

func ResolveOllamaRawBaseURL(configured string) string

ResolveOllamaRawBaseURL returns the raw Ollama base URL without the /v1 suffix, suitable for calling native Ollama endpoints like /api/tags.

func SaveModelCache added in v0.3.0 

func SaveModelCache() error

SaveModelCache saves dynamically discovered models to a local cache file. This allows models to be available immediately on the next startup.
