# 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.
Closes#2910
## Test Plan

Add support for deleting individual chunks from vector stores
- Add abstract remove_chunk() method to EmbeddingIndex base class
- Implement chunk deletion for Faiss provider, SQLite Vec, Milvus,
PGVector
- Placeholder implementations with NotImplementedError for
Chroma/Qdrant/Weaviate

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.
# What does this PR do?
openai/models.py has backward compat entries for litellm model names.
the starter template includes these in the list of registered models.
the inclusion results in duplicate model registrations.
the backward compat is no longer necessary.

## Test Plan
The tests are already supported in the CI and tests the inline providers
and current integration tests.
Note that the `vector_index` fixture will be test `milvus_vec_adapter`,
`faiss_vec_adapter`, and `sqlite_vec_adapter` in
`tests/unit/providers/vector_io/test_vector_io_openai_vector_stores.py`.
Additionally, the integration tests in `integration-vector-io-tests.yml`
runs `tests/integration/vector_io` tests for the following providers:
```python
vector-io-provider: ["inline::faiss", "inline::sqlite-vec", "inline::milvus", "remote::chromadb", "remote::pgvector"]
```

- LlamaCompatInferenceAdapter
## Test Plan
existing unit and integration tests
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.
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?
let's users register models available at
https://integrate.api.nvidia.com/v1/models that isn't already in
llama_stack/providers/remote/inference/nvidia/models.py
## Test Plan
1. run the nvidia distro
2. register a model from https://integrate.api.nvidia.com/v1/models that
isn't already know, as of this writing
nvidia/llama-3.1-nemotron-ultra-253b-v1 is a good example
3. perform inference w/ the model
The vision models are now available at the standard URL, so the
workaround code has been removed. This also simplifies the codebase by
eliminating the need for per-model client caching.
- Remove special URL handling for meta/llama-3.2-11b/90b-vision-instruct
models
- Convert _get_client method to _client property for cleaner API
- Remove unnecessary lru_cache decorator and functools import
- Simplify client creation logic to use single base URL for all models

# What does this PR do?
Resolves https://github.com/meta-llama/llama-stack/issues/2735
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.
## Test Plan
Unit tests:
```bash
./scripts/unit-tests.sh tests/unit/providers/vector_io/ -v
```
Integration tests:
```bash

- fireworks, together do not support Llama-guard 3 8b model anymore
- Need to default to ollama
- current safety shields logic was not correct since the shield_id was
the provider ( which had duplicates )
- Followed similar logic to models
Note: Seems a bit over-engineered but this can now be extended to other
providers and fits in the overall mechanism of how env_vars are used to
manage starter.

which are non-existent )
So need to update that to run with `starter` and use `ollama`
specifically for safety.
# What does this PR do?
Some of our inference providers support passthrough authentication via
`x-llamastack-provider-data` header values. This fixes the providers
that support passthrough auth to not cache their clients to the backend
providers (mostly OpenAI client instances) so that the client connecting
to Llama Stack has to provide those auth values on each and every
request.
## Test Plan
I added some unit tests to ensure we're not caching clients across
requests for all the fixed providers in this PR.
```
uv run pytest -sv tests/unit/providers/inference/test_inference_client_caching.py
```
I also ran some of our OpenAI compatible API integration tests for each
of the changed providers, just to ensure they still work. Note that
these providers don't actually pass all these tests (for unrelated
reasons due to quirks of the Groq and Together SaaS services), but
enough of the tests passed to confirm the clients are still working as
intended.

# 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.

# What does this PR do?
We are now testing the safety capability with the starter image. This
includes a few changes:
* Enable the safety integration test
* Relax the shield model requirements from llama-guard to make it work
with llama-guard3:8b coming from Ollama
* Expose a shield for each inference provider in the starter distro. The
shield will only be registered if the provider is enabled.

- Fix constructor call missing files_api parameter
- Add kvstore field to MilvusVectorIOConfig
- Resolves#2626
# What does this PR do?
[https://github.com/meta-llama/llama-stack/issues/2626]
## Problem
The `MilvusVectorIOAdapter` fails to initialize due to two missing
configuration issues:
1. Missing `files_api` parameter in the constructor call
2. Missing `kvstore` field in the `MilvusVectorIOConfig` class
## Root Cause
1. The adapter constructor expects 3 parameters `(config, inference_api,
files_api)` but the `get_adapter_impl` function only passes 2 parameters
2. The `MilvusVectorIOConfig` class lacks the `kvstore` field that the
adapter's `initialize()` method expects for metadata persistence
## Solution
- Added `files_api = deps.get(Api.files, None)` to safely retrieve files
API from dependencies
- Pass the files_api parameter to MilvusVectorIOAdapter constructor
- Added `kvstore: KVStoreConfig | None = None` field to
MilvusVectorIOConfig
- Maintains backward compatibility since both files_api and kvstore can
be None
Closes#2626
## Test Plan
- [x] Tested with Milvus configuration - server starts successfully

# What does this PR do?
### Summary
This pull request implements support for the OpenAI Vector Store Files
API for the Milvus vector store provider in `llama_stack`. It enables
storing, loading, updating, and deleting file metadata and file contents
in Milvus collections, allowing OpenAI vector store files to be managed
directly within Milvus.
### Main Changes
- **Milvus Vector Store Files API Implementation**
- Implements all required methods for storing, loading, updating, and
deleting vector store file metadata and contents
(`_save_openai_vector_store_file`, `_load_openai_vector_store_file`,
`_load_openai_vector_store_file_contents`,
`_update_openai_vector_store_file`,
`_delete_openai_vector_store_file_from_storage`).
- Uses two Milvus collections: `openai_vector_store_files` (for
metadata) and `openai_vector_store_files_contents` (for chunked file
contents).
- Collections are created dynamically if they do not exist, with
appropriate schema definitions.
- **Collection Name Sanitization**
- Adds a `sanitize_collection_name` utility to ensure Milvus collection
names only contain valid characters (letters, numbers, underscores).
- **Testing**
- Updates test skip logic to include `"inline::milvus"` for cases where
the OpenAI Vector Store Files API is not supported, improving
integration test accuracy.
- **Other Improvements**
- Passes `kvstore` to `MilvusIndex` for consistency.
- Removes obsolete NotImplementedErrors and legacy code for file
storage.
## Test Plan
CI and tested via a test script
## Notes
- `VectorDB` currently uses the `name` as the `identifier` in
`openai_create_vector_store`. We need to add `name` as a field to
`VectorDB` and generate the `identifier` upon creation. OpenAI is not
idempotent with respect to the `name` field that they pass (i.e., you
can pass the same name multiple times and OpenAI will generate a new
identifier). I'll add a follow up PR for this.
- The `Files` api needs to use `files-` as a prefix in the identifier. I
have updated the Vector Store to use the OpenAI prefix `vs_*`.

# What does this PR do?
We were not using conditionals correctly, conditionals can only be used
when the env variable is set, so `${env.ENVIRONMENT:+}` would return
None is ENVIRONMENT is not set.
If you want to create a conditional value, you need to do
`${env.ENVIRONMENT:=}`, this will pick the value of ENVIRONMENT if set,
otherwise will return None.

Simple approach to get some provider pages in the docs.

## Test Plan
1. Create a new `test_run_openai.yaml` and paste the following config in
it:
```yaml
version: '2'
image_name: test-image
apis:
- inference
providers:
inference:
- provider_id: openai
provider_type: remote::openai
config:
max_tokens: 8192
models:
- metadata: {}
model_id: "non-existent-model"
provider_id: openai
model_type: llm
server:
port: 8321
```
And run the server with:
```bash
uv run llama stack run test_run_openai.yaml
```
You should now get a `llama_stack.exceptions.UnsupportedModelError` with
the supported list of models in the error message.

Tested for the following remote inference providers, and they all raise
the `UnsupportedModelError`:
- Anthropic
- Cerebras
- Fireworks
- Gemini
- Groq
- Ollama
- OpenAI
- SambaNova
- Together
- Watsonx

# What does this PR do?
Some templates were still using the old environment variable substition
syntax instead of the new one and were not getting substituted properly.
Also, some places didn't handle the new None vs old empty string ("")
values that come from the conditional environment variable substitution.
This gets the starter and remote-vllm distributions starting again, and
I tested various permutations of the starter as chroma and pgvector
needed some adjustments to their config classes to handle the new
possible `None` values. And, I had to tweak our `Provider` class to also
handle `None` values, for cases where we disable providers in the
starter config via environment variables.
This may not have caught everything that was missed, but I did grep
around quite a bit to try and find anything lingering.
## Test Plan
The following permutations now all run (or attempt to run to the point
of complaining that they can't connect to chroma, vllm, etc) when before
they failed immediately on startup because of bad environment variable
substitions:
```
uv run llama stack run llama_stack/templates/starter/run.yaml
ENABLE_SQLITE_VEC=true uv run llama stack run llama_stack/templates/starter/run.yaml
ENABLE_PGVECTOR=true uv run llama stack run llama_stack/templates/starter/run.yaml
ENABLE_CHROMADB=true uv run llama stack run llama_stack/templates/starter/run.yaml
uv run llama stack run llama_stack/templates/remote-vllm/run.yaml

# What does this PR do?
This commit significantly improves the environment variable substitution
functionality in Llama Stack configuration files:
* The version field in configuration files has been changed from string
to integer type for better type consistency across build and run
configurations.
* The environment variable substitution system for ${env.FOO:} was fixed
and properly returns an error
* The environment variable substitution system for ${env.FOO+} returns
None instead of an empty strings, it better matches type annotations in
config fields
* The system includes automatic type conversion for boolean, integer,
and float values.
* The error messages have been enhanced to provide clearer guidance when
environment variables are missing, including suggestions for using
default values or conditional syntax.
* Comprehensive documentation has been added to the configuration guide
explaining all supported syntax patterns, best practices, and runtime
override capabilities.
* Multiple provider configurations have been updated to use the new
conditional syntax for optional API keys, making the system more
flexible for different deployment scenarios. The telemetry configuration
has been improved to properly handle optional endpoints with appropriate
validation, ensuring that required endpoints are specified when their
corresponding sinks are enabled.
* There were many instances of ${env.NVIDIA_API_KEY:} that should have
caused the code to fail. However, due to a bug, the distro server was
still being started, and early validation wasn’t triggered. As a result,
failures were likely being handled downstream by the providers. I’ve
maintained similar behavior by using ${env.NVIDIA_API_KEY:+}, though I
believe this is incorrect for many configurations. I’ll leave it to each
provider to correct it as needed.
* Environment variable substitution now uses the same syntax as Bash
parameter expansion.
