`roberta` model family

Tasks

Feature Extraction

Supported architectures and task heads

The Hugging Face values below are copied from checkpoint metadata at the recorded revision. The TRTMC task contract comes from the exact E2E recipe. Architecture identity selects or describes a source graph; it does not imply that TRTMC reproduces every Hugging Face head with the same model_type. For example, an encoder recipe may consume the base model and intentionally return hidden states instead of the checkpoint's pretraining or classification logits.

Declared recipes

Each row comes from a model-owned E2E manifest. It declares a test recipe; it is not a live pass receipt for every hardware target.

Family-owned configuration

This family does not declare a family-owned --set namespace. Use the explicit CLI options shown below and the shared configuration namespaces documented in Configure Runtime Behavior.

Family-specific CLI contracts

Inputs and options below are filtered by the declared E2E task and the methods and configuration fields used by that family's native runtime implementation. The global CLI parser accepts a wider union of flags; flags absent here are not declared for this family.

`trtmc encode`

Return the encoder hidden-state representation for text.

Declared recipes: camembert-base, camembert-base-tp4, roberta-base, roberta-base-tp4, roberta-large, roberta-large-tp4, xlm-roberta-base, xlm-roberta-base-tp4

trtmc encode <bundle.bundle> --prompt "<text>"

Supported input or option	Requirement	Runtime behavior
`--prompt <TEXT>`	Required	Text input passed to the encoder.

Bundle lifecycle commands

These commands apply to every declared recipe in this family; they do not add task inputs or model capabilities.

`trtmc build`

Build one exact checkpoint into a TensorRT-Model-Connect bundle.

trtmc build <hf-id> --output <bundle.bundle>

`trtmc inspect`

Inspect bundle metadata, runtime identity, and packaged sections.

trtmc inspect <bundle.bundle>

See the CLI Reference for all options and limitations.
