Fetching Models

The useModels hook from @anuma/sdk/expo fetches available LLM models from the API. The starter app wires it into a modal picker so users can select which model to use for each message.

Hook Initialization

  const { models, isLoading: isLoadingModels } = useModels({
    getToken: getIdentityToken,
    baseUrl: API_BASE_URL,
  });

The hook takes getToken (a function returning a Privy identity token) and an optional baseUrl. It returns the models array and an isLoading flag.

Model Picker

The ModelPickerSheet component renders a searchable modal list of available models. Each model shows its name and provider, with a checkmark on the selected one. The selected model ID is passed to sendMessage on each request.

Model Shape

Each model object contains:

• id — the model identifier passed to the API (e.g. openai/gpt-4o)
• name — display name
• provider — the model provider name
