Properties

accelerationPreference ↔ AccelerationPreference

Preferred hardware acceleration backend for this model.

getter/setter pair

archive ↔ ArchiveArtifact

getter/setter pair

artifactType ↔ ModelArtifactType

High-level artifact classification, complementary to the artifact oneof above. Allows catalog entries to carry a coarse type tag without resolving the full strategy variant.

getter/setter pair

builtIn ↔ bool

getter/setter pair

category ↔ ModelCategory

getter/setter pair

checksumSha256 ↔ String

Lowercase hex SHA-256 checksum for the primary artifact. Per-file checksums for multi-file artifacts live on ModelFileDescriptor.

getter/setter pair

compatibility ↔ ModelRuntimeCompatibility

Framework/format compatibility declarations. framework (field 5) is the canonical/preferred runtime when no explicit preferred_framework is set.

getter/setter pair

contextLength ↔ int

getter/setter pair

createdAtUnixMs ↔ Int64

getter/setter pair

customStrategyId ↔ String

getter/setter pair

downloadSize → int?

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

downloadSizeBytes ↔ Int64

getter/setter pair

downloadUri → Uri?

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

downloadUrl ↔ String

Portable URL/URI string for catalog metadata and download planning. SDK/platform adapters own native HTTP execution, authentication/session state, browser fetch handles, URLSession/background-transfer objects, and permission prompts.

getter/setter pair

expectedFiles ↔ ExpectedModelFiles

Manifest of files that are expected on disk after fetch/extraction.

getter/setter pair

format ↔ ModelFormat

getter/setter pair

framework ↔ InferenceFramework

getter/setter pair

hashCode → int

Calculates a hash code based on the contents of the protobuf.

no setter, inherited

id ↔ String

getter/setter pair

info_ → BuilderInfo

no setter

isAvailable ↔ bool

getter/setter pair

isAvailable → bool

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

isBuiltIn → bool

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

isDownloaded → bool

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

isDownloaded ↔ bool

getter/setter pair

isFrozen → bool

Returns true if this message is marked read-only. Otherwise false.

no setter, inherited

lastUsedAtUnixMs ↔ Int64

getter/setter pair

localFilePath → String?

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

localPath ↔ String

Stable path or URI string after platform adapters have normalized native file handles. Do not place Android SAF/content URI permissions, iOS security-scoped bookmarks, browser FileSystemHandle objects, or other OS-governed capabilities in this C++-owned metadata field.

getter/setter pair

memoryRequiredBytes ↔ Int64

Separate from download_size_bytes: this is the estimated runtime RAM requirement used by compatibility checks and model selection UIs.

getter/setter pair

metadata ↔ ModelInfoMetadata

Structured public catalog metadata, including the model description.

getter/setter pair

multiFile ↔ MultiFileArtifact

getter/setter pair

name ↔ String

getter/setter pair

nullableContextLength → int?

Available on ModelInfo, provided by the ProtoModelInfoHelpers extension

no setter

preferredFramework ↔ InferenceFramework

getter/setter pair

registryStatus ↔ ModelRegistryStatus

Durable registry state. Live byte progress belongs to download_service.DownloadProgress, not ModelInfo.

getter/setter pair

routingPolicy ↔ RoutingPolicy

Hybrid (on-device vs cloud) routing policy for this entry.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

singleFile ↔ SingleFileArtifact

getter/setter pair

source ↔ ModelSource

getter/setter pair

statusMessage ↔ String

getter/setter pair

supportsLora ↔ bool

getter/setter pair

supportsThinking ↔ bool

getter/setter pair

syncPending ↔ bool

getter/setter pair

thinkingPattern ↔ ThinkingTagPattern

Thinking/reasoning metadata. supports_thinking remains the boolean capability flag; this optional pattern declares model-specific tags.

getter/setter pair

unknownFields → UnknownFieldSet

no setter, inherited

updatedAtUnixMs ↔ Int64

getter/setter pair

usageCount ↔ int

getter/setter pair
