+Many model repos have a widget that allows anyone to run inferences directly in the browser. These widgets are powered by [Inference Providers](https://huggingface.co/docs/inference-providers), which provide developers streamlined, unified access to hundreds of machine learning models, backed by our serverless inference partners.
 
-Here are some examples:
-* [Named Entity Recognition](https://huggingface.co/spacy/en_core_web_sm?text=My+name+is+Sarah+and+I+live+in+London) using [spaCy](https://spacy.io/).
-* [Image Classification](https://huggingface.co/google/vit-base-patch16-224) using [🤗 Transformers](https://github.com/huggingface/transformers)
-* [Text to Speech](https://huggingface.co/julien-c/ljspeech_tts_train_tacotron2_raw_phn_tacotron_g2p_en_no_space_train) using [ESPnet](https://github.com/espnet/espnet).
-* [Sentence Similarity](https://huggingface.co/osanseviero/full-sentence-distillroberta3) using [Sentence Transformers](https://github.com/UKPLab/sentence-transformers).
+Here are some examples of current popular models:
 
-You can try out all the widgets [here](https://huggingface-widgets.netlify.app/).

+- [Flux Kontext](https://huggingface.co/black-forest-labs/FLUX.1-Kontext-dev) - Open-weights transformer model for image editing
+- [Falconsai's NSFW Detection](https://huggingface.co/Falconsai/nsfw_image_detection) - Image content moderation
+- [ResembleAI's Chatterbox](https://huggingface.co/ResembleAI/chatterbox) - Production-grade open source text-to-speech model.

 ## Enabling a widget
 
-A widget is automatically created for your model when you upload it to the Hub. To determine which pipeline and widget to display (`text-classification`, `token-classification`, `translation`, etc.), we analyze information in the repo, such as the metadata provided in the model card and configuration files. This information is mapped to a single `pipeline_tag`. We choose to expose **only one** widget per model for simplicity.
+Widgets are displayed when the model is hosted by at least one Inference Provider, ensuring optimal performance and reliability for the model's inference. Providers autonomously chose and control what models they deploy.
+
+The type of widget displayed (text-generation, text to image, etc) is inferred from the model's `pipeline_tag`, a special tag that the Hub tries to compute automatically for all models. The only exception is for the `conversational` widget which is shown on models with a `pipeline_tag` of either `text-generation` or `image-text-to-text`, as long as they’re also tagged as `conversational`. We choose to expose **only one** widget per model for simplicity.
 
-For most use cases, we determine the model type from the tags. For example, if there is `tag: text-classification` in the [model card metadata](./model-cards), the inferred `pipeline_tag` will be `text-classification`.
+For some libraries, such as `transformers`, the model type can be inferred automatically based from configuration files (`config.json`). The architecture can determine the type: for example, `AutoModelForTokenClassification` corresponds to `token-classification`. If you're interested in this, you can see pseudo-code in [this gist](https://gist.github.com/julien-c/857ba86a6c6a895ecd90e7f7cab48046).

 **You can always manually override your pipeline type with `pipeline_tag: xxx` in your [model card metadata](./model-cards#model-card-metadata).** (You can also use the metadata GUI editor to do this).

-## How can I control my model's widget HF-Inference API parameters?
+The list of all providers and the tasks they support is available in [this documentation page](https://huggingface.co/docs/inference-providers/index#partners).
 
-Generally, the HF-Inference API for a model uses the default pipeline settings associated with each task. But if you'd like to change the pipeline's default settings and specify additional inference parameters, you can configure the parameters directly through the model card metadata. Refer [here](https://huggingface.co/docs/inference-providers/detailed_parameters) for some of the most commonly used parameters associated with each task.
+For models without provider support, you can still showcase functionality using [example outputs](#example-outputs) in your model card.
 
-For example, if you want to specify an aggregation strategy for a NER task in the widget:
+You can also click _Ask for provider support_ directly on the model page to encourage providers to serve the model, given there is enough community interest.
 
-```yaml
-inference:
-  parameters:
-    aggregation_strategy: "none"
-```
+## Exploring Models with the Inference Playground

+Before integrating models into your applications, you can test them interactively with the [Inference Playground](https://huggingface.co/playground). The playground allows you to:
 
-```yaml
-inference:
-  parameters:
-    temperature: 0.7
-``` 
-
-Inference Providers allows you to send HTTP requests to models in the Hugging Face Hub programmatically. It is an abstraction layer on top of External providers. ⚡⚡ Learn more about it by reading the [
-Inference Providers documentation](/docs/inference-providers). 
-Finally, you can also deploy all those models to dedicated [Inference Endpoints](https://huggingface.co/docs/inference-endpoints).
+- Test different [chat completion models](https://huggingface.co/models?inference_provider=all&sort=trending&other=conversational) with custom prompts
+- Compare responses across different models
+- Experiment with inference parameters like temperature, max tokens, and more
+- Find the perfect model for your specific use case
+
+The playground uses the same Inference Providers infrastructure that powers the widgets, so you can expect similar performance and capabilities when you integrate the models into your own applications.
