| For more details on how to get a quantized model, refer to the
:doc:`Model Optimization guide <openvino_docs_model_optimization_guide>`, and
:doc:`NNCF tool quantization guide <basic_quantization_flow>`.
Model Caching
#############################
Model Caching helps reduce application startup delays by exporting and reusing the compiled
model automatically. The following two compilation-related metrics are crucial in this area:
| **First Ever Inference Latency (FEIL)**
| Measures all steps required to compile and execute a model on the device for the
first time. It includes model compilation time, the time required to load and
initialize the model on the device and the first inference execution.
| **First Inference Latency (FIL)**
| Measures the time required to load and initialize the pre-compiled model on the
device and the first inference execution.
UMD Dynamic Model Caching
+++++++++++++++++++++++++++++
UMD model caching is a solution enabled by default in the current NPU driver.
It improves time to first inference (FIL) by storing the model in the cache
after the compilation (included in FEIL), based on a hash key. The process
may be summarized in three stages:
1. UMD generates the key from the input IR model and build arguments
2. UMD requests the DirectX Shader cache session to store the model
with the computed key.
3. All subsequent requests to compile the same IR model with the same arguments
use the pre-compiled model, reading it from the cache instead of recompiling.
OpenVINO Model Caching
+++++++++++++++++++++++++++++
OpenVINO Model Caching is a common mechanism for all OpenVINO device plugins and
can be enabled by setting the ``ov::cache_dir`` property. This way, the UMD model
caching is automatically bypassed by the NPU plugin, which means the model
will only be stored in the OpenVINO cache after compilation. When a cache hit
occurs for subsequent compilation requests, the plugin will import the model
instead of recompiling it.
For more details about OpenVINO model caching, see the
:doc:`Model Caching Overview <openvino_docs_OV_UG_Model_caching_overview>`.
Supported Features and properties

The default mode for the NPU device is LATENCY.
Limitations
#############################
* Currently, only the models with static shapes are supported on NPU.
* If the path to the model file includes non-Unicode symbols, such as in Chinese,
the model cannot be used for inference on NPU. It will return an error.
* Running the Alexnet model with NPU may result in a drop in accuracy.
At this moment, the googlenet-v4 model is recommended for classification tasks.

Query Device Properties - Configuration
=======================================
.. meta::
:description: Learn the details on the process of querying different device
properties and configuration values at runtime.
The OpenVINO™ toolkit supports inference with several types of devices (processors or accelerators).
This section provides a high-level description of the process of querying of different device properties and configuration values at runtime.
This article provides an overview of how to query different device properties
and configuration values at runtime.
OpenVINO runtime has two types of properties:
- Read only properties which provide information about the devices (such as device name or execution capabilities, etc.)
and information about configuration values used to compile the model (``ov::CompiledModel``) .
- Mutable properties which are primarily used to configure the ``ov::Core::compile_model`` process and affect final
inference on a specific set of devices. Such properties can be set globally per device via ``ov::Core::set_property``
or locally for particular model in the ``ov::Core::compile_model`` and the ``ov::Core::query_model`` calls.
- **Read only properties** which provide information about devices, such as device
name and execution capabilities, and information about configuration values
used to compile the model - ``ov::CompiledModel``.

can be set globally per device via ``ov::Core::set_property`` or locally for a
particular model in the ``ov::Core::compile_model`` and ``ov::Core::query_model``
calls.
An OpenVINO property is represented as a named constexpr variable with a given string name and a type.
The following example represents a read-only property with a C++ name of ``ov::available_devices``,
a string name of ``AVAILABLE_DEVICES`` and a type of ``std::vector<std::string>``:

The Automatic Device Selection mode, or AUTO for short, uses a "virtual" or a "proxy" device,

The logic behind the choice is as follows:
1. Check what supported devices are available.
2. Check precisions of the input model (for detailed information on precisions read more on the ``ov::device::capabilities``).
3. Select the highest-priority device capable of supporting the given model, as listed in the table below.
4. If model’s precision is FP32 but there is no device capable of supporting it, offload the model to a device supporting FP16.

How AUTO Works
##############
To put it simply, when loading the model to the first device on the list fails, AUTO will try to load it to the next device in line, until one of them succeeds.
What is important, **AUTO starts inference with the CPU of the system by default**, as it provides very low latency and can start inference with no additional delays.

This way, the devices which are much slower in compiling models, GPU being the best example, do not impact inference at its initial stages.
For example, if you use a CPU and a GPU, the first-inference latency of AUTO will be better than that of using GPU alone.
Note that if you choose to exclude CPU from the priority list or disable the initial CPU acceleration feature via ``ov::intel_auto::enable_startup_fallback``, it will be unable to support the initial model compilation stage. The models with dynamic input/output or stateful :doc:`stateful<openvino_docs_OV_UG_model_state_intro>` operations will be loaded to the CPU if it is in the candidate list. Otherwise, these models will follow the normal flow and be loaded to the device based on priority.
