-Components are only loaded and registered when using [`~ModularPipeline.load_components`] or [`~ModularPipeline.load_components`]. The example below uses [`~ModularPipeline.load_components`] to create a second pipeline that reuses all the components from the first one, and assigns it to a different collection
-
-```py
-pipe.load_components()
-pipe2 = ModularPipeline.from_pretrained("YiYiXu/modular-demo-auto", components_manager=comp, collection="test2")
-```
-
-Use the [`~ModularPipeline.null_component_names`] property to identify any components that need to be loaded, retrieve them with [`~ComponentsManager.get_components_by_names`], and then call [`~ModularPipeline.update_components`] to add the missing components.
-
-```py
-pipe2.null_component_names 
-['text_encoder', 'text_encoder_2', 'tokenizer', 'tokenizer_2', 'image_encoder', 'unet', 'vae', 'scheduler', 'controlnet']
-
-comp_dict = comp.get_components_by_names(names=pipe2.null_component_names)
-pipe2.update_components(**comp_dict)
-```
-
-To add individual components, use the [`~ComponentsManager.add`] method. This registers a component with a unique id.
-
-```py
-from diffusers import AutoModel
-
-text_encoder = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
-component_id = comp.add("text_encoder", text_encoder)
-comp
-```
-
-Use [`~ComponentsManager.remove`] to remove a component using their id.
-
-```py
-comp.remove("text_encoder_139917733042864")
-```
-
-## Retrieve a component
-
-The [`ComponentsManager`] provides several methods to retrieve registered components.
-
-### get_one
-
-The [`~ComponentsManager.get_one`] method returns a single component and supports pattern matching for the `name` parameter. If multiple components match, [`~ComponentsManager.get_one`] returns an error.
-
-| Pattern     | Example                          | Description                               |
-|-------------|----------------------------------|-------------------------------------------|
-| exact       | `comp.get_one(name="unet")`      | exact name match                          |
-| wildcard    | `comp.get_one(name="unet*")`     | names starting with "unet"                |
-| exclusion   | `comp.get_one(name="!unet")`     | exclude components named "unet"           |
-| or          | `comp.get_one(name="unet&#124;vae")`  | name is "unet" or "vae"                   |
-
-[`~ComponentsManager.get_one`] also filters components by the `collection` argument or `load_id` argument.
-
-```py
-comp.get_one(name="unet", collection="sdxl")
-```
-
-### get_components_by_names
-
-The [`~ComponentsManager.get_components_by_names`] method accepts a list of names and returns a dictionary mapping names to components. This is especially useful with [`ModularPipeline`] since they provide lists of required component names and the returned dictionary can be passed directly to [`~ModularPipeline.update_components`].
-
-```py
-component_dict = comp.get_components_by_names(names=["text_encoder", "unet", "vae"])
-{"text_encoder": component1, "unet": component2, "vae": component3}
-```
-
-## Duplicate detection
-
-It is recommended to load model components with [`ComponentSpec`] to assign components with a unique id that encodes their loading parameters. This allows [`ComponentsManager`] to automatically detect and prevent duplicate model instances even when different objects represent the same underlying checkpoint.
-
-```py
-from diffusers import ComponentSpec, ComponentsManager
-from transformers import CLIPTextModel
-
-comp = ComponentsManager()
-
-# Create ComponentSpec for the first text encoder
-spec = ComponentSpec(name="text_encoder", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", type_hint=AutoModel)
-# Create ComponentSpec for a duplicate text encoder (it is same checkpoint, from the same repo/subfolder)
-spec_duplicated = ComponentSpec(name="text_encoder_duplicated", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder", type_hint=CLIPTextModel)
-
-# Load and add both components - the manager will detect they're the same model
-comp.add("text_encoder", spec.load())
-comp.add("text_encoder_duplicated", spec_duplicated.load())
-```
-
-This returns a warning with instructions for removing the duplicate.
+Components loaded by the pipeline are automatically registered in the manager. You can inspect them right away.
 
-```py
-ComponentsManager: adding component 'text_encoder_duplicated_139917580682672', but it has duplicate load_id 'stabilityai/stable-diffusion-xl-base-1.0|text_encoder|null|null' with existing components: text_encoder_139918506246832. To remove a duplicate, call `components_manager.remove('<component_id>')`.
-'text_encoder_duplicated_139917580682672'
-```
-
-You could also add a component without using [`ComponentSpec`] and duplicate detection still works in most cases even if you're adding the same component under a different name.
-
-However, [`ComponentManager`] can't detect duplicates when you load the same component into different objects. In this case, you should load a model with [`ComponentSpec`].
-
-```py
-text_encoder_2 = AutoModel.from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", subfolder="text_encoder")
-comp.add("text_encoder", text_encoder_2)
-'text_encoder_139917732983664'
-```
+## Inspect components
 
-## Collections
+Print the [`ComponentsManager`] to see all registered components, including their class, device placement, dtype, memory size, and load ID.
 
-Collections are labels assigned to components for better organization and management. Add a component to a collection with the `collection` argument in [`~ComponentsManager.add`].
-
-Only one component per name is allowed in each collection. Adding a second component with the same name automatically removes the first component.
+The output below corresponds to the `from_pretrained` example above.
 
 ```py
-from diffusers import ComponentSpec, ComponentsManager
-
-comp = ComponentsManager()
-# Create ComponentSpec for the first UNet
-spec = ComponentSpec(name="unet", repo="stabilityai/stable-diffusion-xl-base-1.0", subfolder="unet", type_hint=AutoModel)
-# Create ComponentSpec for a different UNet
-spec2 = ComponentSpec(name="unet", repo="RunDiffusion/Juggernaut-XL-v9", subfolder="unet", type_hint=AutoModel, variant="fp16")
-
-# Add both UNets to the same collection - the second one will replace the first
-comp.add("unet", spec.load(), collection="sdxl")
-comp.add("unet", spec2.load(), collection="sdxl")

-This makes it convenient to work with node-based systems because you can:
-
-- Mark all models as loaded from one node with the `collection` label.
-- Automatically replace models when new checkpoints are loaded under the same name.
-- Batch delete all models in a collection when a node is removed.
+The table shows models (with device, dtype, and memory info) separately from other components like schedulers and tokenizers. If any models have LoRA adapters, IP-Adapters, or quantization applied, that information is displayed in an additional section at the bottom.
 
 ## Offloading
 
 The [`~ComponentsManager.enable_auto_cpu_offload`] method is a global offloading strategy that works across all models regardless of which pipeline is using them. Once enabled, you don't need to worry about device placement if you add or remove components.
 
 ```py
-comp.enable_auto_cpu_offload(device="cuda")
+manager.enable_auto_cpu_offload(device="cuda")
 ```
 
 All models begin on the CPU and [`ComponentsManager`] moves them to the appropriate device right before they're needed, and moves other models back to the CPU when GPU memory is low.
 
-You can set your own rules for which models to offload first.
+Call [`~ComponentsManager.disable_auto_cpu_offload`] to disable offloading.
+
+```py
+manager.disable_auto_cpu_offload()
+```
