Required range: -9007199254740991 <= x <= 9007199254740991
owned_by
string
required
model_type
enum<string>
required
Available options:
llm,
embeddings,
images,
speech_to_text,
text_to_speech
input_modalities
string[]
required

Modalities this model accepts as input, mirroring the registry's capabilities.modalities.input (e.g. ["text", "image"]). Clients use it to decide whether an attachment — an image, audio clip, or video — can be sent to this model at all.

output_modalities
string[]
required

Modalities this model can produce, mirroring the registry's capabilities.modalities.output. Unconstrained strings rather than a closed enum so a new registry modality reaches clients without a breaking schema change.

parameter_count
integer | null
required

Total parameter count of the weights behind this model, mirroring the registry's modelCard.parameterCount. Null when the registry does not record one (closed-weight API models, or entries nobody has filled in yet).

Required range: -9007199254740991 <= x <= 9007199254740991
active_parameter_count
integer | null
required

Parameters active per token for mixture-of-experts models, mirroring the registry's modelCard.activeParameterCount. Null for dense models and whenever unrecorded.

Required range: -9007199254740991 <= x <= 9007199254740991
release_date
string<date> | null
required

Public release date of the model as an ISO calendar date (YYYY-MM-DD), mirroring the registry's modelCard.releaseDate. Null when unrecorded.

capabilities
object
required

Curated public generation capabilities for this model.
