This PR focuses on improving the developer experience by adding
comprehensive docstrings to the API data models across the Llama Stack.
These docstrings provide detailed explanations for each model and its
fields, making the API easier to understand and use.
**Key changes:**
- **Added Docstrings:** Added reST formatted docstrings to Pydantic
models in the `llama_stack/apis/` directory. This includes models for:
- Agents (`agents.py`)
- Benchmarks (`benchmarks.py`)
- Datasets (`datasets.py`)
- Inference (`inference.py`)
- And many other API modules.
- **OpenAPI Spec Update:** Regenerated the OpenAPI specification
(`docs/_static/llama-stack-spec.yaml` and
`docs/_static/llama-stack-spec.html`) to include the new docstrings.
This will be reflected in the API documentation, providing richer
information to users.
**Impact:**
- Developers using the Llama Stack API will have a better understanding
of the data structures.
- The auto-generated API documentation is now more informative.

**Description**
This PR removes some of the warnings when uv builds the docs
- Errors appear when generating docs about .md files not appearing in
toctree. ~~Adding content to the `providers-gen.py ` file that adds `---
orphan: true ---` to to each file.~~. Added a toctree generator to the
`providers-gen.py` file, this gets rid of the errors in the builds.
- Deletes the `_openai_compat` files, extension of PR #2849
- Adds the `files` APIs section to the `providers` toctree on the index
page
- Manually adds the `--- orphan: true ---` to the advanced apis. Ill try
to find a way to modify the providers code gen so it automatically adds
it, but this fixes the errors.
- Adds the `testing.md` to the `contributing` toctree
- Adds `starting_llama_stack_server.md` to `distributions` toctree
There are some other warnings im still looking at but this PR gets rid
of most of the toctree errors
Theres also an issue with the actual distribution-codegen that I can
investigate in another PR. Opened a bug for it here #2873
We tried to always keep Ollama enabled. However doing so makes the
provider implementation half-assed -- should it error when it cannot
connect to Ollama or not? What happens during periodic model refresh?
Etc. Instead do the same thing we do for vLLM -- use the `OLLAMA_URL` to
conditionally enable the provider.
## Test Plan
Run `uv run llama stack build --template starter --image-type venv
--run` with and without `OLLAMA_URL` set. Verify using
`llama-stack-client provider list` that ollama is correctly enabled.
# What does this PR do?

**What:**
- Added OpenAIChatCompletionTextOnlyMessageContent type for text-only
content validation
- Modified OpenAISystemMessageParam, OpenAIAssistantMessageParam,
OpenAIDeveloperMessageParam, and OpenAIToolMessageParam to use text-only
content type instead of mixed content
- OpenAIUserMessageParam unchanged - still accepts both text and images
- Updated OpenAPI spec files to reflect text-only content restrictions
in schemas
closes#2894
**Why:**
- Enforces OpenAI API compatibility by restricting image content to user
messages only
- Prevents API misuse where images might be sent in message types that
don't support them
- Aligns with OpenAI's actual API behavior where only user messages can
contain multimodal content
- Improves type safety and validation at the API boundary
**Test plan:**
- Added comprehensive parametrized tests covering all 5 OpenAI message
types
- Tests verify text string acceptance for all message types
- Tests verify text list acceptance for all message types
- Tests verify image rejection for system/assistant/developer/tool
messages (ValidationError expected)
- Tests verify user messages still accept images (backward compatibility
maintained)
# What does this PR do?
- Add base_url field to OpenAIConfig with default
"https://api.openai.com/v1"
- Update sample_run_config to support OPENAI_BASE_URL environment
variable
- Modify get_base_url() to return configured base_url instead of
hardcoded value
- Add comprehensive test suite covering:
- Default base URL behavior
- Custom base URL from config
- Environment variable override
- Config precedence over environment variables
- Client initialization with configured URL
- Model availability checks using configured URL
This enables users to configure custom OpenAI-compatible API endpoints
via environment variables or configuration files.

# What does this PR do?
Today, external providers are installed via the `external_providers_dir`
in the config. This necessitates users to understand the `ProviderSpec`
and set up their directories accordingly. This process splits up the
config for the stack across multiple files, directories, and formats.
Most (if not all) external providers today have a
[get_provider_spec](559cb18fbb/src/ramalama_stack/provider.py (L9))
method that sits unused. Utilizing this method rather than the
providers.d route allows for a much easier installation process for
external providers and limits the amount of extra configuration a
regular user has to do to get their stack off the ground.
To accomplish this and wire it throughout the build process, Introduce
the concept of a `module` for users to specify for an external provider
upon build time. In order to facilitate this, align the build and run
spec to use `Provider` class rather than the stringified provider_type
that build currently uses.
For example, say this is in your build config:
```
- provider_id: ramalama
provider_type: remote::ramalama
module: ramalama_stack
```
during build (in the various `build_...` scripts), additionally to
installing any pip dependencies we will also install this module and use
the `get_provider_spec` method to retrieve the ProviderSpec that is
currently specified using `providers.d`.
In production so far, providing instructions for installing external
providers for users has been difficult: they need to install the module
as a pre-req, create the providers.d directory, copy in the provider
spec, and also copy in the necessary build/run yaml files. Accessing an
external provider should be as easy as possible, and pointing to its
installable module aligns more with the rest of our build and dependency
management process.
For now, `external_providers_dir` still exists as an alternate more
declarative method of using external providers.
## Test Plan
added an integration test installing an external provider from module
and more unit test coverage for `get_provider_registry`
( the warning in yellow is expected, the module is installed inside of
the build env, not where we are running the command)

This flips #2823 and #2805 by making the Stack periodically query the
providers for models rather than the providers going behind the back and
calling "register" on to the registry themselves. This also adds support
for model listing for all other providers via `ModelRegistryHelper`.
Once this is done, we do not need to manually list or register models
via `run.yaml` and it will remove both noise and annoyance (setting
`INFERENCE_MODEL` environment variables, for example) from the new user
experience.
In addition, it adds a configuration variable `allowed_models` which can
be used to optionally restrict the set of models exposed from a
provider.

Just like #2805 but for vLLM.
We also make VLLM_URL env variable optional (not required) -- if not
specified, the provider silently sits idle and yells eventually if
someone tries to call a completion on it. This is done so as to allow
this provider to be present in the `starter` distribution.
## Test Plan
Set up vLLM, copy the starter template and set `{ refresh_models: true,
refresh_models_interval: 10 }` for the vllm provider and then run:
```
ENABLE_VLLM=vllm VLLM_URL=http://localhost:8000/v1 \
uv run llama stack run --image-type venv /tmp/starter.yaml
```
Verify that `llama-stack-client models list` brings up the model
correctly from vLLM.
Inline _inference_ providers haven't proved to be very useful -- they
are rarely used. And for good reason -- it is almost never a good idea
to include a complex (distributed) inference engine bundled into a
distributed stateful front-end server serving many other things.
Responsibility should be split properly.
See Discord discussion:
1395849853
For self-hosted providers like Ollama (or vLLM), the backing server is
running a set of models. That server should be treated as the source of
truth and the Stack registry should just be a cache for those models. Of
course, in production environments, you may not want this (because you
know what model you are running statically) hence there's a config
boolean to control this behavior.
_This is part of a series of PRs aimed at removing the requirement of
needing to set `INFERENCE_MODEL` env variables for running Llama Stack
server._
## Test Plan
Copy and modify the starter.yaml template / config and enable
`refresh_models: true, refresh_models_interval: 10` for the ollama
provider. Then, run:
```
LLAMA_STACK_LOGGING=all=debug \
ENABLE_OLLAMA=ollama uv run llama stack run --image-type venv /tmp/starter.yaml
```
See a gargantuan amount of logs, but verify that the provider is
periodically refreshing models. Stop and prune a model from ollama
server, restart the server. Verify that the model goes away when I call
`uv run llama-stack-client models list`
# What does this PR do?
This PR fixes the `DPOAlignmentConfig` schema to use the correct Direct
Preference Optimization (DPO) parameters.
The current schema incorrectly uses PPO-inspired parameters
(`reward_scale`, `reward_clip`, `epsilon`, `gamma`) that are not part of
the DPO algorithm. This PR updates it to use the standard DPO
parameters:
- `beta`: The KL divergence coefficient that controls deviation from the
reference model
- `loss_type`: The type of DPO loss function (sigmoid, hinge, ipo,
kto_pair)
These parameters align with standard DPO implementations like
HuggingFace's TRL library.

Currently, if you test against OpenAI's Vector Stores API the
`client.vector_stores.search` call fails with an invalid vector_db
during routing (see the script referenced in the clickable item under
the Test Plan section).
This PR ensures that `client.vector_stores.search()` is compatible with
OpenAI's Vector Stores API.
Two biggest changes:
1. The `name`, which was previously used as the `vector_db_id`, has been
changed to be consistent with OpenAI's `vs_{uuid}` format.
2. The vector store ID has to be referenced by the ID, the name is not
reliable as every `client.vector_stores.create` results in a new vector
store.
NOTE: I believe this is a breaking change for end users as they'll need
to update their VectorDB identifiers.

# What does this PR do?
This PR adds the keyword search implementation for Milvus. Along with
the implementation for remote Milvus, the tests require us to start a
Milvus containers locally.
In order to verify the implementation, run:
```
pytest tests/unit/providers/vector_io/remote/test_milvus.py -v -s --tb=short --disable-warnings --asyncio-mode=auto

Artificial Intelligence (AI) and Machine Learning (ML) are transforming the world.
AI refers to the simulation of human intelligence in machines, while ML is a subset
of AI that enables computers to learn and improve from experience without being
explicitly programmed. Deep learning, a subset of ML, uses neural networks with
multiple layers to process complex patterns in data.
Key concepts in AI/ML include:
- Supervised Learning: Training with labeled data
- Unsupervised Learning: Finding patterns in unlabeled data
- Reinforcement Learning: Learning through trial and error
- Neural Networks: Computing systems inspired by biological brains

# What does this PR do?
This PR improves documentation clarity around run.yaml file usage. It
adds comprehensive guidance to help users understand that generated
run.yaml files are templates meant to be customized for production use,
not used as-is.
## Changes
- Add new documentation section on customizing run.yaml files
- Clarify that generated run.yaml files are templates, not production
configs
- Add guidance on customization best practices and common scenarios
- Update existing documentation to reference customization guide
- Improve clarity around run.yaml file usage for better user experience
## Test Plan
- Verified new documentation file exists at correct location
- Confirmed documentation is properly integrated into the toctree
structure
- Checked all internal links use correct paths and reference existing
files
- Validated references are added to relevant existing documentation
files
- Documentation build testing will be handled by CI environment
# What does this PR do?
Adds input validation for mode in RagQueryConfig
This will prevent users from inputting search modes other than `vector`
and `keyword` for the time being with `hybrid` to follow when that
functionality is implemented.
## Test Plan
[Describe the tests you ran to verify your changes with result
summaries. *Provide clear instructions so the plan can be easily
re-executed.*]
```
# Check out this PR and enter the LS directory
uv sync --extra dev
```
Run the quickstart
[example](https://llama-stack.readthedocs.io/en/latest/getting_started/#step-3-run-the-demo)
Alter the Agent to include a query_config
```
agent = Agent(
client,
model=model_id,
instructions="You are a helpful assistant",
tools=[
{
"name": "builtin::rag/knowledge_search",
"args": {
"vector_db_ids": [vector_db_id],
"query_config": {
"mode": "i-am-not-vector", # Test for non valid search mode
"max_chunks": 6
}
},
}
],
)
```
Ensure you get the following error:
```
400: {'errors': [{'loc': ['mode'], 'msg': "Value error, mode must be either 'vector' or 'keyword' if supported by the vector_io provider", 'type': 'value_error'}]}
```
## Running unit tests
```
uv sync --extra dev
uv run pytest tests/unit/rag/test_rag_query.py -v
```
[//]: # (## Documentation)
# What does this PR do?
the "rfc" directory has only a single document in it, and its the
original RFC for creating Llama Stack
simply the project directory structure by moving this into the "docs"
directory and renaming it to "original_rfc" to preserve the context of
the doc
## Why did you do this?
A simplified top-level directory structure helps keep the project
simpler and prevents misleading new contributors into thinking we use it
(we really don't)

# What does this PR do?
This PR refactors and the VectorIO backend logic for `sqlite-vec` and
adds unit tests and fixtures to make it easy to test both `sqlite-vec`
and `milvus`.
Key changes:
- `sqlite-vec` migrated to `kvstore` registry
- added in-memory cache for sqlite-vec to be consistent with `milvus`
- default fixtures moved to `conftest.py`
- removed redundant tests from sqlite`-vec`
- made `test_vector_io_openai_vector_stores.py` more easily extensible
## Test Plan
Unit tests added testing inline providers.
