Functions

func DetectPipelineTag 

func DetectPipelineTag(modelDir string) string

DetectPipelineTag reads config.json in modelDir and returns a local pipeline tag for routing. Sentence-transformers repositories are treated as embedding models even when the hub metadata was not persisted in older manifests.

func EnsureLocalModelFiles 

func EnsureLocalModelFiles(modelDir string, m *LocalModel) (bool, error)

func EnsureModelDir 

func EnsureModelDir(baseDir, namespace, name string) error

EnsureModelDir creates the directory for a model if it doesn't exist.

func FindMMProj 

func FindMMProj(modelDir string) string

FindMMProj looks for a multimodal projector GGUF file in the model directory.

func FindMMProjFiles added in v0.9.37 

func FindMMProjFiles(modelDir string) ([]string, error)

FindMMProjFiles returns multimodal projector GGUF files ordered with conventionally named mmproj files first, then metadata-detected projectors.

func FindMTPFiles added in v0.9.37 

func FindMTPFiles(modelDir string) ([]string, error)

FindMTPFiles returns Multi-Token Prediction companion GGUF files.

func FindWeightGGUFRelPaths added in v0.9.37 

func FindWeightGGUFRelPaths(modelDir string) ([]string, error)

FindWeightGGUFRelPaths returns main-model GGUF paths while excluding filename- and metadata-identified companion modules.

func InferenceModelID 

func InferenceModelID(lm *LocalModel) string

InferenceModelID returns the public model identifier used for local inference APIs.

func IsASRArchitecture 

func IsASRArchitecture(architecture string) bool

IsASRArchitecture reports whether the HuggingFace architecture is an automatic speech recognition model.

func IsASRModelFamily 

func IsASRModelFamily(name string) bool

IsASRModelFamily reports whether a model id/name belongs to a known ASR family served by the Python ASR runtime.

func IsEmbeddingArchitecture 

func IsEmbeddingArchitecture(architecture string) bool

IsEmbeddingArchitecture reports whether the HuggingFace architecture is treated as a local embedding model by csghub-lite.

func IsPythonEmbeddingArchitecture added in v0.9.8 

func IsPythonEmbeddingArchitecture(architecture string) bool

IsPythonEmbeddingArchitecture reports whether the HuggingFace architecture is supported by csghub-lite's Python embedding runtime.

func ListModelsInNamespace 

func ListModelsInNamespace(baseDir, namespace string) ([]string, error)

ListModelsInNamespace returns all model directories under a namespace.

func ListNamespaces 

func ListNamespaces(baseDir string) ([]string, error)

ListNamespaces returns all namespace directories under the model base dir.

func ManifestPath 

func ManifestPath(baseDir, namespace, name string) string

func MaxModelLen added in v0.9.31 

func MaxModelLen(modelDir string, format Format) (int64, error)

MaxModelLen returns the model's native maximum context length. GGUF models carry this value in their metadata header; SafeTensors models use the Hugging Face config.json stored alongside the weights.

func ModelDir 

func ModelDir(baseDir, namespace, name string) string

ModelDir returns the directory for a specific model.

func PublicModelIDs 

func PublicModelIDs(models []*LocalModel) map[string]string

PublicModelIDs returns stable short model IDs keyed by each model's full storage ID. OpenCSG and imported models preserve short IDs for compatibility; external registry models use source/namespace/name and therefore do not collide across registries.

func RegistryModelDir added in v0.9.53 

func RegistryModelDir(baseDir, artifactSource, namespace, name string) string

RegistryModelDir keeps historical OpenCSG/import paths stable while namespacing external registries so identical repository IDs can coexist.

func RemoveRegistryModelDir added in v0.9.53 

func RemoveRegistryModelDir(baseDir, artifactSource, namespace, name string) error

func SaveManifestInDir 

func SaveManifestInDir(modelDir string, m *LocalModel) error

SaveManifestInDir writes a manifest to a prepared model directory before it is installed.
