"2. **Size**: Llamas typically grow to be between 5 and 6 feet (1.5 to 1.8 meters) tall at the shoulder and weigh between 280 and 450 pounds (127 to 204 kilograms).\n", "Their packs they bore, until the very end.\n",
"3. **Habitat**: Llamas are native to the Andean highlands, where they live in herds and roam freely. They are well adapted to the harsh, high-altitude climate of the Andes.\n", "The Spanish came, with guns and strife,\n",
"4. **Diet**: Llamas are herbivores and feed on a variety of plants, including grasses, leaves, and shrubs. They are known for their ability to digest plant material that other animals cannot.\n", "But llamas stood firm, for life.\n",
"5. **Behavior**: Llamas are social animals and live in herds. They are known for their intelligence, curiosity, and strong sense of self-preservation.\n",
"6. **Purpose**: Llamas have been domesticated for thousands of years and have been used for a variety of purposes, including:\n",
"\t* **Pack animals**: Llamas are often used as pack animals, carrying goods and supplies over long distances.\n",
"\t* **Fiber production**: Llama wool is highly valued for its softness, warmth, and durability.\n",
"\t* **Meat**: Llama meat is consumed in some parts of the world, particularly in South America.\n",
"\t* **Companionship**: Llamas are often kept as pets or companions, due to their gentle nature and intelligence.\n",
"\n", "\n",
"Overall, llamas are fascinating animals that have been an integral part of Andean culture for thousands of years.\u001b[0m\n" "Now, they roam free, in fields so wide,\n",

How do I use it?*\\n\\nYou can finetune using any of our recipes with the ``lora_`` prefix, e.g. :ref:`lora_finetune_single_device<lora_finetune_recipe_label>`. These recipes utilize\\nLoRA-enabled model builders, which we support for all our models, and also use the ``lora_`` prefix, e.g.\\nthe :func:`torchtune.models.llama3.llama3` model has a corresponding :func:`torchtune.models.llama3.lora_llama3`.\\nWe aim to provide a comprehensive set of configurations to allow you to get started with training with LoRA quickly,\\njust specify any config with ``_lora`` in its name, e.g:\\n\\n.. code-block:: bash\\n\\n tune run lora_finetune_single_device --config llama3/8B_lora_single_device\\n\\n\\nThere are two sets of parameters to customize LoRA to suit your needs. Firstly, the parameters which control\\nwhich linear layers LoRA should be applied to in the model:\\n\\n* ``lora_attn_modules: List[str]`` accepts a list of strings specifying which layers of the model to apply\\n LoRA to:\\n\\n * ``q_proj`` applies LoRA to the query projection layer.\\n * ``k_proj`` applies LoRA to the key projection layer.\\n * ``v_proj`` applies LoRA to the value projection layer.\\n * ``output_proj`` applies LoRA to the attention output projection layer.\\n\\n Whilst adding more layers to be fine-tuned may improve model accuracy,\\n this will come at the cost of increased memory usage and reduced training speed.\\n\\n* ``apply_lora_to_mlp: Bool`` applies LoRA to the MLP in each transformer layer.\\n* ``apply_lora_to_output: Bool`` applies LoRA to the model's final output projection.\\n This is\", document_id='url-doc-0', token_count=512)\n",

The magnitude component\\nis a scalar vector that adjusts the scale, while the direction component corresponds to the original LoRA decomposition and\\nupdates the orientation of weights.\\n\\nDoRA adds a small overhead to LoRA training due to the addition of the magnitude parameter, but it has been shown to\\nimprove the performance of LoRA, particularly at low ranks.\\n\\n*Sounds great! How do I use it?*\\n\\nMuch like LoRA and QLoRA, you can finetune using DoRA with any of our LoRA recipes. We use the same model builders for LoRA\\nas we do for DoRA, so you can use the ``lora_`` version of any model builder with ``use_dora=True``. For example, to finetune\\n:func:`torchtune.models.llama3.llama3_8b` with DoRA, you would use :func:`torchtune.models.llama3.lora_llama3_8b` with ``use_dora=True``:\\n\\n.. code-block:: bash\\n\\n tune run lora_finetune_single_device --config llama3/8B_lora_single_device \\\\\\n model.use_dora=True\\n\\n.. code-block:: yaml\\n\\n model:\\n _component_: torchtune.models.lora_llama3_8b\\n use_dora: True\\n\\nSince DoRA extends LoRA', document_id='url-doc-0', token_count=512)\n",

"## Agentic API 101\n",
"\n",
"This document talks about the Agentic APIs in Llama Stack. Before you begin, please ensure Llama Stack is installed and set up by following the [Getting Started Guide](https://llama-stack.readthedocs.io/en/latest/getting_started/index.html).\n",
"\n",
"Starting Llama 3.1 you can build agentic applications capable of:\n",
"\n",
"- breaking a task down and performing multi-step reasoning.\n",
"- using tools to perform some actions\n",
" - built-in: the model has built-in knowledge of tools like search or code interpreter\n",
" - zero-shot: the model can learn to call tools using previously unseen, in-context tool definitions\n",
"- providing system level safety protections using models like Llama Guard.\n",
"\n",
"An agentic app requires a few components:\n",
"- ability to run inference on the underlying Llama series of models\n",
"- ability to run safety checks using the Llama Guard series of models\n",
"- ability to execute tools, including a code execution environment, and loop using the model's multi-step reasoning process\n",
"\n",
"All of these components are now offered by a single Llama Stack Distribution. Llama Stack defines and standardizes these components and many others that are needed to make building Generative AI applications smoother. Various implementations of these APIs are then assembled together via a **Llama Stack Distribution**.\n",

# Quickstart Guide
Llama-Stack allows you to configure your distribution from various providers, allowing you to focus on going from zero to production super fast.
This guide will walk you through how to build a local distribution, using ollama as an inference provider.
We also have a set of notebooks walking you through how to use Llama-Stack APIs:
- Inference
- Prompt Engineering
- Chatting with Images
- Tool Calling
- Memory API for RAG
- Safety API
- Agentic API
Below, we will learn how to get started with Ollama as an inference provider, please note the steps for configuring your provider will vary a little depending on the service. However, the user experience will remain universal-this is the power of Llama-Stack.
Prototype locally using Ollama, deploy to the cloud with your favorite provider or own deployment. Use any API from any provider while focussing on development.
# Ollama Quickstart Guide # Ollama Quickstart Guide

"Prompt Guard is a classifier model trained on a large corpus of attacks, which is capable of detecting both explicitly malicious prompts (Jailbreaks) as well as prompts that contain injected inputs (Prompt Injections). We suggest a methodology of fine-tuning the model to application-specific data to achieve optimal results.\n",

"PromptGuard is a BERT model that outputs only labels; unlike Llama Guard, it doesn't need a specific prompt structure or configuration. The input is a string that the model labels as safe or unsafe (at two different levels).\n",

"Llama Guard 3 comes in three flavors now: Llama Guard 3 1B, Llama Guard 3 8B and Llama Guard 3 11B-Vision. The first two models are text only, and the third supports the same vision understanding capabilities as the base Llama 3.2 11B-Vision model. All the models are multilingual–for text-only prompts–and follow the categories defined by the ML Commons consortium. Check their respective model cards for additional details on each model and its performance.\n",

"## Agentic API 101\n",
"\n",
"This document talks about the Agentic APIs in Llama Stack. Before you begin, please ensure Llama Stack is installed and set up by following the [Getting Started Guide](https://llama-stack.readthedocs.io/en/latest/getting_started/index.html).\n",
"\n",
"Starting Llama 3.1 you can build agentic applications capable of:\n",
"\n",
"- breaking a task down and performing multi-step reasoning.\n",
"- using tools to perform some actions\n",
" - built-in: the model has built-in knowledge of tools like search or code interpreter\n",
" - zero-shot: the model can learn to call tools using previously unseen, in-context tool definitions\n",
"- providing system level safety protections using models like Llama Guard.\n",
"\n",
"An agentic app requires a few components:\n",
"- ability to run inference on the underlying Llama series of models\n",
"- ability to run safety checks using the Llama Guard series of models\n",
"- ability to execute tools, including a code execution environment, and loop using the model's multi-step reasoning process\n",
"\n",
"All of these components are now offered by a single Llama Stack Distribution. Llama Stack defines and standardizes these components and many others that are needed to make building Generative AI applications smoother. Various implementations of these APIs are then assembled together via a **Llama Stack Distribution**.\n",

"#### Key Highlights:\n",
"- **`WeatherTool` Class**: A custom tool that processes weather information requests, supporting location and optional date parameters.\n",
"- **Agent Creation**: The `create_weather_agent` function sets up an agent equipped with the `WeatherTool`, allowing for weather queries in natural language.\n",
"- **Simulation of API Call**: The `run_impl` method simulates fetching weather data. This method can be replaced with an actual API integration for real-world usage.\n",
"- **Interactive Example**: The `weather_example` function shows how to use the agent to handle user queries regarding the weather, providing step-by-step responses."
