# Providers Overview
|
|
|
|
The goal of Llama Stack is to build an ecosystem where users can easily swap out different implementations for the same API. Examples for these include:
|
|
- LLM inference providers (e.g., Fireworks, Together, AWS Bedrock, Groq, Cerebras, SambaNova, vLLM, etc.),
|
|
- Vector databases (e.g., ChromaDB, Weaviate, Qdrant, FAISS, PGVector, etc.),
|
|
- Safety providers (e.g., Meta's Llama Guard, AWS Bedrock Guardrails, etc.)
|
|
|
|
Providers come in two flavors:
|
|
- **Remote**: the provider runs as a separate service external to the Llama Stack codebase. Llama Stack contains a small amount of adapter code.
|
|
- **Inline**: the provider is fully specified and implemented within the Llama Stack codebase. It may be a simple wrapper around an existing library, or a full fledged implementation within Llama Stack.
|
|
|
|
Importantly, Llama Stack always strives to provide at least one fully inline provider for each API so you can iterate on a fully featured environment locally.
|
|
|
|
## Agents
|
|
Run multi-step agentic workflows with LLMs with tool usage, memory (RAG), etc.
|
|
|
|
## DatasetIO
|
|
Interfaces with datasets and data loaders.
|
|
|
|
## Eval
|
|
Generates outputs (via Inference or Agents) and perform scoring.
|
|
|
|
## Inference
|
|
Runs inference with an LLM.
|
|
|
|
## Post Training
|
|
Fine-tunes a model.
|
|
|
|
## Safety
|
|
Applies safety policies to the output at a Systems (not only model) level.
|
|
|
|
## Scoring
|
|
Evaluates the outputs of the system.
|
|
|
|
## Telemetry
|
|
Collects telemetry data from the system.
|
|
|
|
## Tool Runtime
|
|
Is associated with the ToolGroup resouces.
|
|
|
|
## Vector IO
|
|
|
|
Vector IO refers to operations on vector databases, such as adding documents, searching, and deleting documents.
|
|
Vector IO plays a crucial role in [Retreival Augmented Generation (RAG)](../..//building_applications/rag), where the vector
|
|
io and database are used to store and retrieve documents for retrieval.
|
|
|
|
#### Vector IO Providers
|
|
The following providers (i.e., databases) are available for Vector IO:
