+
+    Supported providers - IBM watsonx.ai, IBM watsonx.orchestrate, Red Hat AI
+    inference on IBM Cloud, OpenAI SDK compatible providers, IBM Consulting
+    Advantage.
+
+    Construct via the ``__init__`` (which initialises the underlying provider
+    client) and then call the instance methods, e.g.::
+
+        inf = InferenceClient(
+            provider="watsonx",
+            api_key=WX_API_KEY,
+            url=WX_URL,
+            project_id=PROJECT_ID,
+            model_id="ibm/granite-3-8b-instruct",
+        )
+        models = inf.get_models()
+        results = inf.run_iterative_inference(messages, number_of_iterations=3)
+
+    Switching models / agents
+    -------------------------
+    The model (or WXO agent) does NOT have to be supplied up front. You can:
+
+    - pass ``model_id`` / ``agent_id`` to ``__init__`` (the default for all calls),
+    - switch the default later with ``set_model(...)`` / ``set_agent(...)``,
+    - or override per call by passing ``model_id`` / ``agent_id`` directly to
+    ``run_chat_inference`` / ``run_iterative_inference``.
+
+    Example::
+
+        inf = InferenceClient(provider="ica", api_key=ICA_API_KEY)  # no model up front
+        inf.set_model(inf.get_models()[0])                          # pick one later
+        inf.run_chat_inference(messages)                            # uses it
+        inf.run_chat_inference(messages, model_id="other-model")    # one-off override
+
+    Unified ``url`` parameter
+    -------------------------
+    A single ``url`` parameter replaces the old per-provider URL arguments. Its
+    meaning depends on the provider (see ``__init__``). The legacy ``base_url``
+    and ``instance_url`` keyword arguments are still accepted as aliases.
+
+    Progress bars
+    -------------
+    ``run_iterative_inference`` and ``run_batch_inference`` show a marimo
+    progress bar by default. Toggle the default with ``progress_bar`` on
+    ``__init__``, or override per call with the ``progress_bar`` argument. When
+    marimo is not installed (or not running in a marimo context) the bar is
+    silently skipped and the loops behave identically.
+
+    The provider client created during initialisation is stored on
+    ``self.client`` and used implicitly by all methods. ``self.provider`` and
+    ``self.model_id`` / ``self.agent_id`` act as defaults that individual method
+    calls may override.

+        region:     RHAI region, default "us-east" (rhai only).
+

+        ------------
+        auth_type:    One of:
+                        "ibm_iam" (default) - IBM Cloud
+                        "cpd" - IBM watsonx orchestrate software (cloud pak for data),

+        is_local:     True when targeting a local Developer Edition server.
+        api_version:  WXO API version, default "v1".
+        agent_id:     Default WXO agent ID used by chat / iterative methods.
+
+        model / agent (optional)
+        -------------------------
+        model_id / agent_id are optional up front. They can be set later via
+        ``set_model`` / ``set_agent`` or overridden per call. See the class
+        docstring.
+
+        progress_bar:
+            Whether to show a marimo progress bar while iterating in
+            ``run_iterative_inference`` / ``run_batch_inference``. Defaults to
+            True. This is the instance default; each call accepts a
+            ``progress_bar`` argument to override it. Silently ignored when
+            marimo is not installed or not running in a marimo context.

+        Run the same single-turn inference over a list of objects.
+
+        Each object in ``items`` is converted into a messages list (via
+        ``message_builder``) and sent through ``run_chat_inference``. Results are
+        returned in the same order as the input, one entry per item - even in
+        async mode.
+
+        Unlike ``run_iterative_inference`` (which is a single growing
+        conversation), this runs each item as an independent, stateless call -
+        useful for scoring / extracting / classifying a collection of documents.
+
+        Parameters
+        ----------
+        items:
+            List of input objects. Each may be anything ``message_builder`` knows
+            how to turn into a messages list. If ``message_builder`` is omitted,
+            each item must already be a messages list

+            Override the instance provider. One of "watsonx", "openai", "rhai",
+            "wxo", "ica".
+        model_id:
+            Required for openai / rhai / ica; used for wxo when no agent_id is
+            given. Defaults to the instance model_id.
+        params:
+            Extra generation params forwarded per call. Defaults to the instance
+            params.
+        agent_id:
+            WXO agent ID (wxo provider only). Defaults to the instance agent_id.
+        on_item_complete:
+            Optional callback(index, item, result) called after each item - use
+            this to persist results to a database as they come in. ``result`` is
+            None when that item failed. In async mode it fires as each call
+            finishes (so not necessarily in input order) and may run on a worker
+            thread, so keep it thread-safe.
+        progress_bar:
+            Show a marimo progress bar over the items. Defaults to the instance
+            ``self.progress_bar`` setting. Silently ignored when marimo is
+            unavailable.
+        include_item:
+            When True, each return entry is a dict
+            ``{"index": int, "item": <original pre-message_builder item>,
+            "result": <response dict or None>}`` instead of the bare result.
+        async_mode:
+            When True, dispatch the calls concurrently using a thread pool
+            (the provider clients are blocking I/O, so threads give real
+            parallelism). Order of execution is not preserved, but the returned
+            list is still aligned positionally with ``items``.
+        max_workers:
+            Maximum number of concurrent worker threads when ``async_mode`` is
+            True. Defaults to 8.
+
+        Returns
+        -------
+        A list aligned positionally with ``items``. Each entry is the raw
+        response dict (or None for items that failed) when ``include_item`` is
+        False, or the ``{"index", "item", "result"}`` dict when it is True.
