Exposes model metadata for a provider and model from the registry.

load_full_metadata(model_spec)

Functions

get_model_metadata(provider_id, model_name)

@spec get_model_metadata(atom(), String.t()) :: {:ok, map()} | {:error, term()}

Exposes model metadata for a provider and model from the registry.

This is the canonical way to access model metadata, delegating to the provider registry's internal metadata storage.

Parameters

  • provider_id - Provider atom identifier (e.g., :anthropic)
  • model_name - Model name string (e.g., "claude-3-sonnet")

Returns

{:ok, metadata_map} if found, {:error, reason} otherwise.

Examples

{:ok, metadata} = ReqLLM.Model.Metadata.get_model_metadata(:anthropic, "claude-3-sonnet")
metadata["cost"]
#=> %{"input" => 3.0, "output" => 15.0}

load_full_metadata(model_spec)

@spec load_full_metadata(String.t()) :: {:ok, map()} | {:error, term()}

Loads full metadata from JSON files for enhanced model creation.

Attempts to load complete model metadata from provider files in the priv/models_dev directory for the given model specification.

Parameters

  • model_spec - Model specification string in "provider:model" format

Returns

{:ok, metadata_map} if metadata is found and valid, {:error, reason} otherwise.

Examples

{:ok, metadata} = ReqLLM.Model.Metadata.load_full_metadata("anthropic:claude-3-sonnet")
metadata["cost"]
#=> %{"input" => 3.0, "output" => 15.0}
