# Llama Stack Playground
|
|
|
|
```{note}
|
|
The Llama Stack Playground is currently experimental and subject to change. We welcome feedback and contributions to help improve it.
|
|
```
|
|
|
|
The Llama Stack Playground is an simple interface which aims to:
|
|
- Showcase **capabilities** and **concepts** of Llama Stack in an interactive environment
|
|
- Demo **end-to-end** application code to help users get started to build their own applications
|
|
- Provide an **UI** to help users inspect and understand Llama Stack API providers and resources
|
|
|
|
## Key Features
|
|
|
|
#### Playground
|
|
Interactive pages for users to play with and explore Llama Stack API capabilities.
|
|
|
|
##### Chatbot
|
|

:autoplay:

|
:playsinline:
|
|

|
|
:loop:
|
|
:width: 100%
|
|
```
|
|
- **Chat**: Chat with Llama models.
|
|
- This page is a simple chatbot that allows you to chat with Llama models. Under the hood, it uses the `/inference/chat-completion` streaming API to send messages to the model and receive responses.
|
|
- **RAG**: Uploading documents to memory_banks and chat with RAG agent
|
|
- This page allows you to upload documents as a `memory_bank` and then chat with a RAG agent to query information about the uploaded documents.
|
|
- Under the hood, it uses Llama Stack's `/agents` API to define and create a RAG agent and chat with it in a session.
|
|
|
|
##### Evaluations

|
|
```
|
|
- **Evaluations (Scoring)**: Run evaluations on your AI application datasets.
|
|
- This page demonstrates the flow evaluation API to run evaluations on your custom AI application datasets. You may upload your own evaluation datasets and run evaluations using available scoring functions.
|
|
- Under the hood, it uses Llama Stack's `/scoring` API to run evaluations on selected scoring functions.
|
|
|
|
```{eval-rst}

|
|
```
|
|
- **Evaluations (Generation + Scoring)**: Use pre-registered evaluation tasks to evaluate an model or agent candidate
|
|
- This page demonstrates the flow for evaluation API to evaluate an model or agent candidate on pre-defined evaluation tasks. An evaluation task is a combination of dataset and scoring functions.
|
|
- Under the hood, it uses Llama Stack's `/eval` API to run generations and scorings on specified evaluation configs.
|
|
- In order to run this page, you may need to register evaluation tasks and datasets as resources first through the following commands.
|
|
```bash
|
|
$ llama-stack-client datasets register \
|
|
--dataset-id "mmlu" \
|
|
--provider-id "huggingface" \
|
|
--url "https://huggingface.co/datasets/llamastack/evals" \
|
|
--metadata '{"path": "llamastack/evals", "name": "evals__mmlu__details", "split": "train"}' \
|
|
--schema '{"input_query": {"type": "string"}, "expected_answer": {"type": "string"}, "chat_completion_input": {"type": "string"}}'
|
|
```
|
|
|
|
```bash
|
|
$ llama-stack-client benchmarks register \
|
|
--eval-task-id meta-reference-mmlu \
|
|
--provider-id meta-reference \
|
|
--dataset-id mmlu \
|
|
--scoring-functions basic::regex_parser_multiple_choice_answer
|
|
```

```
|
|
- **API Providers**: Inspect Llama Stack API providers
|
|
- This page allows you to inspect Llama Stack API providers and resources.
|
|
- Under the hood, it uses Llama Stack's `/providers` API to get information about the providers.
|
|
|
|
- **API Resources**: Inspect Llama Stack API resources
|
|
- This page allows you to inspect Llama Stack API resources (`models`, `datasets`, `memory_banks`, `benchmarks`, `shields`).
|
|
- Under the hood, it uses Llama Stack's `/<resources>/list` API to get information about each resources.
|
|
- Please visit [Core Concepts](https://llama-stack.readthedocs.io/en/latest/concepts/index.html) for more details about the resources.
