# 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)

# What does this PR do?
- Added ability to specify `required_scope` when declaring an API. This
is part of the `@webmethod` decorator.
- If auth is enabled, a user can access an API only if
`user.attributes['scope']` includes the `required_scope`
- We add `required_scope='telemetry.read'` to the telemetry read APIs.
## Test Plan
CI with added tests
1. Enable server.auth with github token
2. Observe `client.telemetry.query_traces()` returns 403

# What does this PR do?
currently `print` is being used with custom formatting to achieve
telemetry output in the console_span_processor
This causes telemetry not to show up in log files when using
`LLAMA_STACK_LOG_FILE`. During testing it looks like telemetry is not
being captured when it is
switch to using Rich formatting with the logger and then strip the
formatting off when a log file is being used so the formatting looks
normal

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?
Adds type guards in /distribution/inspect.py and ignores a valid-type
mypy error in library_client.py. This PR is part of issue #2647 . I'm
rather unsure whether ignoring the valid-type error is correct in this
case. It appears that args[0] is interpreted as [any] but I didn't find
any way to specify the type.

# What does this PR do?
<!-- Provide a short summary of what this PR does and why. Link to
relevant issues if applicable. -->
I noticed a few issues with my implementation of the search mode
validation for RagQuery.
This PR replaces the check for search mode in RagQuery with a Literal.
There were issues before with
```
TypeError: Object of type RAGSearchMode is not JSON serializable
```
When using
```
query_config = RAGQueryConfig(max_chunks=6, mode="vector").model_dump()
```
It also fixes the fact that despite user input "vector" was always the
used search mode.
<!-- If resolving an issue, uncomment and update the line below -->
<!-- Closes #[issue-number] -->
## Test Plan
<!-- Describe the tests you ran to verify your changes with result
summaries. *Provide clear instructions so the plan can be easily

Verify that a chosen search mode works when using Rag Query or use below
agent config:
```
agent = Agent(
client,
model=model_id,
instructions="You are a helpful assistant",
tools=[
{
"name": "builtin::rag/knowledge_search",
"args": {

"query_config": {
"mode": "keyword",
"max_chunks": 6
}
},
}

## 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"]
```

Both ` python -m llama_stack.distribution.server.server --config
llama_stack/templates/starter/run.yaml` and ` python -m
llama_stack.distribution.server.server
llama_stack/templates/starter/run.yaml` should run the server. Same for
`--template starter`.

- Remove --no-cache flags from uv pip install commands to enable caching
- Mount host uv cache directory to container for persistent caching
- Set UV_LINK_MODE=copy to prevent uv using hardlinks
- When building the starter image
o Build time reduced from ~4:45 to ~3:05 on subsequent builds
(environment specific)
o Eliminates re-downloading of 3G+ of data on each build
o Cache size: ~6.2G (when building starter image)
Fixes excessive data downloads during distro container builds.

This PR updates model registration and lookup behavior to be slightly
more general / flexible. See
https://github.com/meta-llama/llama-stack/issues/2843 for more details.
Note that this change is backwards compatible given the design of the
`lookup_model()` method.

After https://github.com/meta-llama/llama-stack/pull/2818, SIGINT will
print a stack trace. This is because uvicorn re-raises SIGINT and it
gets converted by Python internal signal handler (default handles
SIGINT) to KeyboardInterrupt exception. We know simply catch the
exception to get a clean exit, this is not changing the behavior on
SIGINT.
## Test Plan
Run the server, hit Ctrl+C or `kill -2 <server pid>` and expect a clean
exit with no stack trace.

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.

When we call `construct_stack()`, providers are instantiated and
`initialize()` is called. This call can end up doing _anything_ at all
-- specifically, providers are free to create long running background
tasks as part of this. If we wrapped this within a `asyncio.run()` as in
the current code, these tasks get canceled when the stack construction
finishes. This is not correct. The PR addresses the issue by creating a
persistent event loop which is used for both the stack as well as for
running the uvicorn server. In other words, the lifetime of the
providers (and downstream async code) is now the same as the lifetime of
the uvicorn server.
## Test Plan
This should not affect any current code since we don't have background
tasks created right now. However,
https://github.com/meta-llama/llama-stack/pull/2805 will start using
this functionality.

If I am running `uv run llama stack run --image-type venv` it should not
be saying to me "Conda detected" because I am pretty clearly telling it
I need venv. The root cause is the offending line.
# 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
- POST /v1/models accepts optional provider_model_id
- ModelsRoutingTable.register_model handler ensures it is non-None,
providing a default
usage of Model.provider_model_id will no longer need to detect None
Move sentence-transformers to be the first embedding in the list of
models. This ensures it will always be the default and is more
consistent then having the default change based on what env variables
are available
