# Evals
# Evaluations
[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/drive/10CHyykee9j2OigaIcRv47BKG9mrNm0tJ?usp=sharing)
The Llama Stack provides a set of APIs in Llama Stack for supporting running evaluations of LLM applications.
- `/datasetio` + `/datasets` API
- `/scoring` + `/scoring_functions` API
- `/eval` + `/benchmarks` API
Llama Stack provides the building blocks needed to run benchmark and application evaluations. This guide will walk you through how to use these components to run open benchmark evaluations. Visit our [Evaluation Concepts](../concepts/evaluation_concepts.md) guide for more details on how evaluations work in Llama Stack, and our [Evaluation Reference](../references/evals_reference/index.md) guide for a comprehensive reference on the APIs.
### 1. Open Benchmark Model Evaluation
This first example walks you through how to evaluate a model candidate served by Llama Stack on open benchmarks. We will use the following benchmark:
- [MMMU](https://arxiv.org/abs/2311.16502) (A Massive Multi-discipline Multimodal Understanding and Reasoning Benchmark for Expert AGI): Benchmark designed to evaluate multimodal models.
- [SimpleQA](https://openai.com/index/introducing-simpleqa/): Benchmark designed to access models to answer short, fact-seeking questions.
This guides walks you through the process of evaluating an LLM application built using Llama Stack. Checkout the [Evaluation Reference](../references/evals_reference/index.md) guide goes over the sets of APIs and developer experience flow of using Llama Stack to run evaluations for benchmark and application use cases. Checkout our Colab notebook on working examples with evaluations [here](https://colab.research.google.com/drive/10CHyykee9j2OigaIcRv47BKG9mrNm0tJ?usp=sharing).
#### 1.1 Running MMMU
- We will use a pre-processed MMMU dataset from [llamastack/mmmu](https://huggingface.co/datasets/llamastack/mmmu). The preprocessing code is shown in in this [Github Gist](https://gist.github.com/yanxi0830/118e9c560227d27132a7fd10e2c92840). The dataset is obtained by transforming the original [MMMU/MMMU](https://huggingface.co/datasets/MMMU/MMMU) dataset into correct format by `inference/chat-completion` API.
## Application Evaluation
[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/meta-llama/llama-stack/blob/main/docs/getting_started.ipynb)
Llama Stack offers a library of scoring functions and the `/scoring` API, allowing you to run evaluations on your pre-annotated AI application datasets.
In this example, we will show you how to:
1. Build an Agent with Llama Stack
2. Query the agent's sessions, turns, and steps
3. Evaluate the results.
##### Building a Search Agent
```python
import datasets
from llama_stack_client.lib.agents.agent import Agent
from llama_stack_client.lib.agents.event_logger import EventLogger
ds = datasets.load_dataset(path="llamastack/mmmu", name="Agriculture", split="dev")
ds = ds.select_columns(["chat_completion_input", "input_query", "expected_answer"])
eval_rows = ds.to_pandas().to_dict(orient="records")
```
- Next, we will run evaluation on an model candidate, we will need to:
- Define a system prompt
- Define an EvalCandidate
- Run evaluate on the dataset
```python
SYSTEM_PROMPT_TEMPLATE = """
You are an expert in Agriculture whose job is to answer questions from the user using images.
First, reason about the correct answer.
Then write the answer in the following format where X is exactly one of A,B,C,D:
Answer: X
Make sure X is one of A,B,C,D.
If you are uncertain of the correct answer, guess the most likely one.

session_id = agent.create_session("test-session")
#### 1.2. Running SimpleQA
- We will use a pre-processed SimpleQA dataset from [llamastack/evals](https://huggingface.co/datasets/llamastack/evals/viewer/evals__simpleqa) which is obtained by transforming the input query into correct format accepted by `inference/chat-completion` API.
- Since we will be using this same dataset in our next example for Agentic evaluation, we will register it using the `/datasets` API, and interact with it through `/datasetio` API.
for prompt in user_prompts:
response = agent.create_turn(
messages=[
{
"role": "user",
"content": prompt,
}
],
session_id=session_id,
)
```python
simpleqa_dataset_id = "huggingface::simpleqa"
_ = client.datasets.register(
dataset_id=simpleqa_dataset_id,
provider_id="huggingface",

},
)
eval_rows = client.datasetio.get_rows_paginated(
dataset_id=simpleqa_dataset_id,
rows_in_page=5,
)
```
```python
client.benchmarks.register(
benchmark_id="meta-reference::simpleqa",

},
"max_tokens": 4096,
"repeat_penalty": 1.0,
},
},
},
)
for log in EventLogger().log(response):
log.print()
```
### 2. Agentic Evaluation
- In this example, we will demonstrate how to evaluate a agent candidate served by Llama Stack via `/agent` API.
- We will continue to use the SimpleQA dataset we used in previous example.
- Instead of running evaluation on model, we will run the evaluation on a Search Agent with access to search tool. We will define our agent evaluation candidate through `AgentConfig`.
##### Query Agent Execution Steps
Now, let's look deeper into the agent's execution steps and see if how well our agent performs.
```python
# query the agents session
from rich.pretty import pprint
session_response = client.agents.session.retrieve(
session_id=session_id,
agent_id=agent.agent_id,
)
pprint(session_response)
```
As a sanity check, we will first check if all user prompts is followed by a tool call to `brave_search`.
```python
num_tool_call = 0
for turn in session_response.turns:
for step in turn.steps:
if (
step.step_type == "tool_execution"
and step.tool_calls[0].tool_name == "brave_search"
):
num_tool_call += 1
print(
f"{num_tool_call}/{len(session_response.turns)} user prompts are followed by a tool call to `brave_search`"
)
```
##### Evaluate Agent Responses
Now, we want to evaluate the agent's responses to the user prompts.
1. First, we will process the agent's execution history into a list of rows that can be used for evaluation.
2. Next, we will label the rows with the expected answer.
3. Finally, we will use the `/scoring` API to score the agent's responses.
```python
agent_config = {
"model": "meta-llama/Llama-3.1-405B-Instruct",
"instructions": "You are a helpful assistant",
"sampling_params": {
"strategy": {
"type": "greedy",

## Testing & Evaluation
Llama Stack provides built-in tools for evaluating your applications:
1. **Benchmarking**: Test against standard datasets
2. **Application Evaluation**: Score your application's outputs
3. **Custom Metrics**: Define your own evaluation criteria
Here's how to set up basic evaluation:
```python
# Create an evaluation task
response = client.benchmarks.register(
benchmark_id="my_eval",
dataset_id="my_dataset",
scoring_functions=["accuracy", "relevance"],
)
# Run evaluation
job = client.eval.run_eval(
benchmark_id="my_eval",
benchmark_config={
"type": "app",
"eval_candidate": {"type": "agent", "config": agent_config},
},
)
# Get results

@ -17,25 +17,31 @@ Here are some example PRs to help you get started:
## Testing the Provider
Before running tests, you must have required dependencies installed. This depends on the providers or distributions you are testing. For example, if you are testing the `together` distribution, you should install dependencies via `llama stack build --template together`.
### 1. Integration Testing
- Create integration tests that use real provider instances and configurations
- For remote services, test actual API interactions
- Avoid mocking at the provider level since adapter layers tend to be thin
- Reference examples in {repopath}`tests/api`
### 2. Unit Testing (Optional)
- Add unit tests for provider-specific functionality
- See examples in {repopath}`llama_stack/providers/tests/inference/test_text_inference.py`
Integration tests are located in {repopath}`tests/integration`. These tests use the python client-SDK APIs (from the `llama_stack_client` package) to test functionality. Since these tests use client APIs, they can be run either by pointing to an instance of the Llama Stack server or "inline" by using `LlamaStackAsLibraryClient`.
Consult {repopath}`tests/integration/README.md` for more details on how to run the tests.
Note that each provider's `sample_run_config()` method (in the configuration class for that provider)
typically references some environment variables for specifying API keys and the like. You can set these in the environment or pass these via the `--env` flag to the test command.
### 2. Unit Testing
Unit tests are located in {repopath}`tests/unit`. Provider-specific unit tests are located in {repopath}`tests/unit/providers`. These tests are all run automatically as part of the CI process.
### 3. Additional end-to-end testing
### 3. End-to-End Testing
1. Start a Llama Stack server with your new provider
2. Test using client requests
3. Verify compatibility with existing client scripts in the [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main) repository
4. Document which scripts are compatible with your provider
2. Verify compatibility with existing client scripts in the [llama-stack-apps](https://github.com/meta-llama/llama-stack-apps/tree/main) repository

This guide will walk you through the steps to get started with building a Llama Stack distribution from scratch with your choice of API providers.
### Setting your log level
In order to specify the proper logging level users can apply the following environment variable `LLAMA_STACK_LOGGING` with the following format:
`LLAMA_STACK_LOGGING=server=debug;core=info`
Where each category in the following list:
- all
- core
- server
- router
- inference
- agents
- safety
- eval
- tools
- client
Can be set to any of the following log levels:
- debug
- info
- warning
- error
- critical
The default global log level is `info`. `all` sets the log level for all components.
### Llama Stack Build
In order to build your own distribution, we recommend you clone the `llama-stack` repository.

- `llm-as-judge::base`: LLM-As-Judge with custom judge prompt & model.
- `braintrust::factuality`: Factuality scorer from [braintrust](https://github.com/braintrustdata/autoevals).
- `basic::subset_of`: Basic checking if generated answer is a subset of expected answer.

# Testing Llama Stack Providers
The Llama Stack is designed as a collection of Lego blocks -- various APIs -- which are composable and can be used to quickly and reliably build an app. We need a testing setup which is relatively flexible to enable easy combinations of these providers.
We use `pytest` and all of its dynamism to enable the features needed. Specifically:
- We use `pytest_addoption` to add CLI options allowing you to override providers, models, etc.
- We use `pytest_generate_tests` to dynamically parametrize our tests. This allows us to support a default set of (providers, models, etc.) combinations but retain the flexibility to override them via the CLI if needed.
- We use `pytest_configure` to make sure we dynamically add appropriate marks based on the fixtures we make.
- We use `pytest_collection_modifyitems` to filter tests based on the test config (if specified).
## Pre-requisites
Your development environment should have been configured as per the instructions in the
[CONTRIBUTING.md](../../../CONTRIBUTING.md) file. In particular, make sure to install the test extra
dependencies. Below is the full configuration:
```bash
$ cd llama-stack
$ uv sync --extra dev --extra test
$ uv pip install -e .
$ source .venv/bin/activate
```
## Common options
All tests support a `--providers` option which can be a string of the form `api1=provider_fixture1,api2=provider_fixture2`. So, when testing safety (which need inference and safety APIs) you can use `--providers inference=together,safety=meta_reference` to use these fixtures in concert.
Depending on the API, there are custom options enabled. For example, `inference` tests allow for an `--inference-model` override, etc.
By default, we disable warnings and enable short tracebacks. You can override them using pytest's flags as appropriate.
Some providers need special API keys or other configuration options to work. You can check out the individual fixtures (located in `tests/<api>/fixtures.py`) for what these keys are. These can be specified using the `--env` CLI option. You can also have it be present in the environment (exporting in your shell) or put it in the `.env` file in the directory from which you run the test. For example, to use the Together fixture you can use `--env TOGETHER_API_KEY=<...>`
## Inference
We have the following orthogonal parametrizations (pytest "marks") for inference tests:
- providers: (meta_reference, together, fireworks, ollama)
- models: (llama_8b, llama_3b)
If you want to run a test with the llama_8b model with fireworks, you can use:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m "fireworks and llama_8b" \
--env FIREWORKS_API_KEY=<...>
```
You can make it more complex to run both llama_8b and llama_3b on Fireworks, but only llama_3b with Ollama:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m "fireworks or (ollama and llama_3b)" \
--env FIREWORKS_API_KEY=<...>
```
Finally, you can override the model completely by doing:
```bash
pytest -s -v llama_stack/providers/tests/inference/test_text_inference.py \
-m fireworks \
--inference-model "meta-llama/Llama3.1-70B-Instruct" \
--env FIREWORKS_API_KEY=<...>
```
> [!TIP]
> If you’re using `uv`, you can isolate test executions by prefixing all commands with `uv run pytest...`.
## Agents
The Agents API composes three other APIs underneath:
- Inference
- Safety
- Memory
Given that each of these has several fixtures each, the set of combinations is large. We provide a default set of combinations (see `tests/agents/conftest.py`) with easy to use "marks":
- `meta_reference` -- uses all the `meta_reference` fixtures for the dependent APIs
- `together` -- uses Together for inference, and `meta_reference` for the rest
- `ollama` -- uses Ollama for inference, and `meta_reference` for the rest
An example test with Together:
```bash
pytest -s -m together llama_stack/providers/tests/agents/test_agents.py \
--env TOGETHER_API_KEY=<...>
```
If you want to override the inference model or safety model used, you can use the `--inference-model` or `--safety-shield` CLI options as appropriate.
If you wanted to test a remotely hosted stack, you can use `-m remote` as follows:
```bash
pytest -s -m remote llama_stack/providers/tests/agents/test_agents.py \
--env REMOTE_STACK_URL=<...>
```
## Test Config
If you want to run a test suite with a custom set of tests and parametrizations, you can define a YAML test config under llama_stack/providers/tests/ folder and pass the filename through `--config` option as follows:
```
pytest llama_stack/providers/tests/ --config=ci_test_config.yaml
```
### Test config format
Currently, we support test config on inference, agents and memory api tests.
Example format of test config can be found in ci_test_config.yaml.
## Test Data
We encourage providers to use our test data for internal development testing, so to make it easier and consistent with the tests we provide. Each test case may define its own data format, and please refer to our test source code to get details on how these fields are used in the test.

# Llama Stack Integration Tests
You can run llama stack integration tests on either a Llama Stack Library or a Llama Stack endpoint.
To test on a Llama Stack library with certain configuration, run
We use `pytest` for parameterizing and running tests. You can see all options with:
```bash
LLAMA_STACK_CONFIG=./llama_stack/templates/cerebras/run.yaml pytest -s -v tests/api/inference/
```
or just the template name
```bash
LLAMA_STACK_CONFIG=together pytest -s -v tests/api/inference/
cd tests/integration
# this will show a long list of options, look for "Custom options:"
pytest --help
```
To test on a Llama Stack endpoint, run
Here are the most important options:
- `--stack-config`: specify the stack config to use. You have three ways to point to a stack:
- a URL which points to a Llama Stack distribution server
- a template (e.g., `fireworks`, `together`) or a path to a run.yaml file
- a comma-separated list of api=provider pairs, e.g. `inference=fireworks,safety=llama-guard,agents=meta-reference`. This is most useful for testing a single API surface.
- `--env`: set environment variables, e.g. --env KEY=value. this is a utility option to set environment variables required by various providers.
Model parameters can be influenced by the following options:
- `--text-model`: comma-separated list of text models.
- `--vision-model`: comma-separated list of vision models.
- `--embedding-model`: comma-separated list of embedding models.
- `--safety-shield`: comma-separated list of safety shields.
- `--judge-model`: comma-separated list of judge models.
- `--embedding-dimension`: output dimensionality of the embedding model to use for testing. Default: 384
Each of these are comma-separated lists and can be used to generate multiple parameter combinations.
Experimental, under development, options:
- `--record-responses`: record new API responses instead of using cached ones
- `--report`: path where the test report should be written, e.g. --report=/path/to/report.md
## Examples
Run all text inference tests with the `together` distribution:
```bash
LLAMA_STACK_BASE_URL=http://localhost:8089 pytest -s -v tests/api/inference
pytest -s -v tests/api/inference/test_text_inference.py \
--stack-config=together \
--text-model=meta-llama/Llama-3.1-8B-Instruct
```
## Report Generation
Run all text inference tests with the `together` distribution and `meta-llama/Llama-3.1-8B-Instruct`:
To generate a report, run with `--report` option
```bash
LLAMA_STACK_CONFIG=together pytest -s -v report.md tests/api/ --report
pytest -s -v tests/api/inference/test_text_inference.py \
--stack-config=together \
--text-model=meta-llama/Llama-3.1-8B-Instruct
```
## Common options
Depending on the API, there are custom options enabled
- For tests in `inference/` and `agents/, we support `--inference-model` (to be used in text inference tests) and `--vision-inference-model` (only used in image inference tests) overrides
- For tests in `vector_io/`, we support `--embedding-model` override
- For tests in `safety/`, we support `--safety-shield` override
- The param can be `--report` or `--report <path>`
If path is not provided, we do a best effort to infer based on the config / template name. For url endpoints, path is required.
Running all inference tests for a number of models:
```bash
TEXT_MODELS=meta-llama/Llama-3.1-8B-Instruct,meta-llama/Llama-3.1-70B-Instruct
VISION_MODELS=meta-llama/Llama-3.2-11B-Vision-Instruct
EMBEDDING_MODELS=all-MiniLM-L6-v2
TOGETHER_API_KEY=...
pytest -s -v tests/api/inference/ \
--stack-config=together \
--text-model=$TEXT_MODELS \
--vision-model=$VISION_MODELS \
--embedding-model=$EMBEDDING_MODELS
```
Same thing but instead of using the distribution, use an adhoc stack with just one provider (`fireworks` for inference):
```bash
FIREWORKS_API_KEY=...
pytest -s -v tests/api/inference/ \
--stack-config=inference=fireworks \
--text-model=$TEXT_MODELS \
--vision-model=$VISION_MODELS \
--embedding-model=$EMBEDDING_MODELS
```
Running Vector IO tests for a number of embedding models:
```bash
EMBEDDING_MODELS=all-MiniLM-L6-v2
pytest -s -v tests/api/vector_io/ \
--stack-config=inference=sentence-transformers,vector_io=sqlite-vec \
--embedding-model=$EMBEDDING_MODELS
```
