# What does this PR do?
When clients called the Open AI API with invalid input that wasn't
caught by our own Pydantic API validation but instead only caught by the
backend inference provider, that backend inference provider was
returning a HTTP 400 error. However, we were wrapping that into a HTTP
500 error, obfuscating the actual issue from calling clients and
triggering OpenAI client retry logic.
This change adjusts our existing `translate_exception` method in
`server.py` to wrap `openai.BadRequestError` as HTTP 400 errors, passing
through the string representation of the error message to the calling
user so they can see the actual input validation error and correct it. I
tried changing this in a few other places, but ultimately
`translate_exception` was the only real place to handle this for both
streaming and non-streaming requests across all inference providers that
use the OpenAI server APIs.
This also tightens up our validation a bit for the OpenAI chat
completions API, to catch empty `messages` parameters, invalid
`tool_choice` parameters, invalid `tools` items, or passing
`tool_choice` when `tools` isn't given.
Lastly, this extends our OpenAI API chat completions verifications to
also check for consistent input validation across providers. Providers
behind Llama Stack should automatically pass all the new tests due to
the input validation added here, but some of the providers fail this
test when not run behind Llama Stack due to differences in how they
handle input validation and errors.
(Closes#1951)
## Test Plan
To test this, start an OpenAI API verification stack:
```
llama stack run --image-type venv tests/verifications/openai-api-verification-run.yaml
```
Then, run the new verification tests with your provider(s) of choice:
```
python -m pytest -s -v \
tests/verifications/openai_api/test_chat_completion.py \
--provider openai-llama-stack
python -m pytest -s -v \
tests/verifications/openai_api/test_chat_completion.py \
--provider together-llama-stack

# What does this PR do?
Previously, when a streaming client would disconnect before we were
finished streaming the entire response, an error like the below would
get raised from the `sse_generator` function in
`llama_stack/distribution/server/server.py`:
```
AttributeError: 'coroutine' object has no attribute 'aclose'. Did you mean: 'close'?
```
This was because we were calling `aclose` on a coroutine instead of the
awaited value from that coroutine. This change fixes that, so that we
save off the awaited value and then can call `aclose` on it if we
encounter an `asyncio.CancelledError`, like we see when a client
disconnects before we're finished streaming.
The other changes in here are to add a simple set of tests for the happy
path of our SSE streaming and this client disconnect path.
That unfortunately requires adding one more dependency into our unit
test section of pyproject.toml since `server.py` requires loading some
of the telemetry code for me to test this functionality.
## Test Plan
I wrote the tests in `tests/unit/server/test_sse.py` first, verified the
client disconnected test failed before my change, and that it passed
afterwards.

python -m pytest -s -v tests/unit/server/test_sse.py

# What does this PR do?
The together inference provider was throwing a stack trace every time it
shut down, as it was trying to call a non-existent `close` method on the
AsyncTogether client. While fixing that, I also adjusted its shutdown
logic to close the OpenAI client if we've created one of those, as that
client does have a `close` method.
In testing that, I also realized we were defaulting to treating all
requests as streaming requests instead of defaulting to non-streaming.
So, this flips that default to non-streaming to match how the other
providers work.
## Test Plan
I tested this by ensuring the together inference provider no longer
spits out a long stack trace when shutting it down and by running the
OpenAI API chat completion verification suite to ensure the change in
default streaming logic didn't mess anything else up.

# What does this PR do?
We were passing a dict into the compat mixin for OpenAI Completions when
using Llama models with Fireworks, and that was breaking some strong
typing code that was added in openai_compat.py. We shouldn't have been
converting these params to a dict in that case anyway, so this adjusts
things to pass the params in as their actual original types when calling
the OpenAIChatCompletionToLlamaStackMixin.
## Test Plan
All of the fireworks provider verification tests were failing due to
some OpenAI compatibility cleanup in #1962. The changes in that PR were
good to make, and this just cleans up the fireworks provider code to
stop passing in untyped dicts to some of those `openai_compat.py`
methods since we have the original strongly-typed parameters we can pass
in.

Allow users to name an agent and use the name in telemetry instead of
relying on randomly generated agent_ids. This improves the developer
experience by making it easier to find specific agents in telemetry
logs.
Closes#1832
## Test Plan
- Added tests to verify the agent name is properly stored and retrieved
- Ran `uv run -- pytest -v
tests/integration/telemetry/test_telemetry.py::test_agent_name_filtering`
from the root of the project and made sure the tests pass
- Ran `uv run -- pytest -v
tests/integration/telemetry/test_telemetry.py::test_agent_query_spans`
to verify existing code without agent names still works correctly
## Use Example
```
agent = Agent(
llama_stack_client,
model=text_model_id,
name="CustomerSupportAgent", # New parameter
instructions="You are a helpful customer support assistant"
)
session_id = agent.create_session(f"test-session-{uuid4()}")
```
## Implementation Notes
- Agent names are optional string parameters with no additional
validation
- Names are not required to be unique - multiple agents can have the
same name
- The agent_id remains the unique identifier for an agent

# What does this PR do?
Some of our multi-turn verification tests were failing because I had
accidentally marked content as a required field in the OpenAI chat
completion request assistant messages, but it's actually optional. It is
required for messages from other roles, but assistant is explicitly
allowed to be optional.
Similarly, the assistant message tool_calls field should default to None
instead of an empty list.
These two changes get the openai-llama-stack verification test back to
100% passing, just like it passes 100% when not behind Llama Stack. They
also increase the pass rate of some of the other providers in the
verification test, but don't get them to 100%.
## Test Plan
I started a Llama Stack server setup to run all the verification tests
(requires OPENAI_API_KEY env variable)
```
llama stack run --image-type venv tests/verifications/openai-api-verification-run.yaml
```
Then, I manually ran the verification tests to see which were failing,
fix them, and ran them again after these changes to ensure they were all
passing.

# What does this PR do?
Fixes a crash that occurred when building a stack as a container image
via the interactive wizard without supplying --template or --config.
- Root cause: template_or_config was None; only the container path
relies on that parameter, which later reaches subprocess.run() and
triggers
`TypeError: expected str, bytes or os.PathLike object, not NoneType.`
- Change: in `_run_stack_build_command_from_build_config` we now fall
back to the freshly‑written build‑spec file whenever both optional
sources are missing. Also adds a spy‑based unit test that asserts a
valid string path is passed to build_image() for container builds.
### Closes#1976
## Test Plan
- New unit test: test_build_path.py. Monkey‑patches build_image,
captures the fourth argument, and verifies it is a real path
- Manual smoke test:
```
llama stack build --image-type container
# answer wizard prompts
```
Build proceeds into Docker without raising the previous TypeError.
## Future Work
Harmonise `build_image` arguments so every image type receives the same
inputs, eliminating this asymmetric special‑case.
# What does this PR do?
Build failures are hard to read, sometimes we get errors like:
```
Error building stack: 'key'
```
Which are difficult to debug without a proper trace.

If `llama stack build` fails you get a traceback now.

Fixes: #1955
Since 0.2.0, the vLLM gets an empty list (vs ``None``in 0.1.9 and
before) when there are no tools configured which causes the issue
described in #1955 p. This patch avoids sending the 'tools' param to the
vLLM altogether instead of an empty list.
It also adds a small unit test to avoid regressions.
The OpenAI
[specification](https://platform.openai.com/docs/api-reference/chat/create)
does not explicitly state that the list cannot be empty but I found this
out through experimentation and it might depend on the actual remote
vllm. In any case, as this parameter is Optional, is best to skip it
altogether if there's no tools configured.

## What does this PR do?
This PR improves the server's request routing logic by ensuring built-in
FastAPI paths such as `/docs`, `/redoc`, `/openapi.json`,
`/favicon.ico`, and `/static` bypass the custom `TracingMiddleware`.
This prevents unnecessary tracing logic for documentation and static
file requests, ensuring better performance and cleaner logs.
Additionally, it adds proper metadata (`title`, `description`, and
`version`) to the FastAPI application initialization and updates the
requirements document accordingly.
[//]: # (Closes#1822 )
---
## Test Plan
- Ran the server locally with `uvicorn` using the provided `run.yaml`
config
- Verified that:
- FastAPI docs (`/docs`, `/redoc`) load correctly without triggering the
custom tracing middleware
- All other routes still go through the middleware and trace logic
- Application metadata appears as expected in the OpenAPI docs
To reproduce:
1. Start the server with `python server.py --template <template-name>`
2. Navigate to `/docs` and `/redoc`
3. Confirm that no extra trace headers are added for those routes
4. Confirm other API endpoints behave as expected and include
`x-trace-id` in the response headers

Froze the requirements file to include many of the other libraries that
have been added in the past few releases to make install easier.

Now a separate thread is started to execute training jobs. Training
requests now return job ID before the job completes. (Which fixes API
timeouts for any jobs that take longer than a minute.)
Note: the scheduler code is meant to be spun out in the future into a
common provider service that can be reused for different APIs and
providers. It is also expected to back the /jobs API proposed here:

Hence its somewhat generalized form which is expected to simplify its
adoption elsewhere in the future.

or job removal). This work will belong to follow-up PRs.

## 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.*]
Added unit tests for the scheduler module. For the API coverage, did
manual testing and was able to run a training cycle on GPU. The initial
call returned job ID before the training completed, as (now) expected.
Artifacts are returned as expected.

```
The integration test is currently disabled for the provider. I will look
into how it can be enabled in a different PR / issue context.

# What does this PR do?
TLDR: Changes needed to get 100% passing tests for OpenAI API
verification tests when run against Llama Stack with the `together`,
`fireworks`, and `openai` providers. And `groq` is better than before,
at 88% passing.
This cleans up the OpenAI API support for image message types
(specifically `image_url` types) and handling of the `response_format`
chat completion parameter. Both of these required a few more Pydantic
model definitions in our Inference API, just to move from the
not-quite-right stubs I had in place to something fleshed out to match
the actual OpenAI API specs.
As part of testing this, I also found and fixed a bug in the litellm
implementation of openai_completion and openai_chat_completion, so the
providers based on those should actually be working now.
The method `prepare_openai_completion_params` in
`llama_stack/providers/utils/inference/openai_compat.py` was improved to
actually recursively clean up input parameters, including handling of
lists, dicts, and dumping of Pydantic models to dicts. These changes
were required to get to 100% passing tests on the OpenAI API
verification against the `openai` provider.
With the above, the together.ai provider was passing as well as it is
without Llama Stack. But, since we have Llama Stack in the middle, I
took the opportunity to clean up the together.ai provider so that it now
also passes the OpenAI API spec tests we have at 100%. That means
together.ai is now passing our verification test better when using an
OpenAI client talking to Llama Stack than it is when hitting together.ai
directly, without Llama Stack in the middle.
And, another round of work for Fireworks to improve translation of
incoming OpenAI chat completion requests to Llama Stack chat completion
requests gets the fireworks provider passing at 100%. The server-side
fireworks.ai tool calling support with OpenAI chat completions and Llama
4 models isn't great yet, but by pointing the OpenAI clients at Llama
Stack's API we can clean things up and get everything working as
expected for Llama 4 models.
## Test Plan
### OpenAI API Verification Tests
I ran the OpenAI API verification tests as below and 100% of the tests
passed.
First, start a Llama Stack server that runs the `openai` provider with
the `gpt-4o` and `gpt-4o-mini` models deployed. There's not a template
setup to do this out of the box, so I added a
`tests/verifications/openai-api-verification-run.yaml` to do this.
First, ensure you have the necessary API key environment variables set:
```
export TOGETHER_API_KEY="..."
export FIREWORKS_API_KEY="..."
export OPENAI_API_KEY="..."
```
Then, run a Llama Stack server that serves up all these providers:
```
llama stack run \
--image-type venv \
tests/verifications/openai-api-verification-run.yaml
```
Finally, generate a new verification report against all these providers,
both with and without the Llama Stack server in the middle.
```
python tests/verifications/generate_report.py \
--run-tests \
--provider \
together \
fireworks \
groq \
openai \
together-llama-stack \
fireworks-llama-stack \
groq-llama-stack \
openai-llama-stack
```
You'll see that most of the configurations with Llama Stack in the
middle now pass at 100%, even though some of them do not pass at 100%
when hitting the backend provider's API directly with an OpenAI client.
### OpenAI Completion Integration Tests with vLLM:
I also ran the smaller `test_openai_completion.py` test suite (that's
not yet merged with the verification tests) on multiple of the
providers, since I had to adjust the method signature of
openai_chat_completion a bit and thus had to touch lots of these
providers to match. Here's the tests I ran there, all passing:
```
VLLM_URL="http://localhost:8000/v1" INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct" llama stack build --template remote-vllm --image-type venv --run
```
in another terminal
```
LLAMA_STACK_CONFIG=http://localhost:8321 INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct" python -m pytest -v tests/integration/inference/test_openai_completion.py --text-model "meta-llama/Llama-3.2-3B-Instruct"
```
### OpenAI Completion Integration Tests with ollama
```
INFERENCE_MODEL="llama3.2:3b-instruct-q8_0" llama stack build --template ollama --image-type venv --run
```
in another terminal
```
LLAMA_STACK_CONFIG=http://localhost:8321 INFERENCE_MODEL="llama3.2:3b-instruct-q8_0" python -m pytest -v tests/integration/inference/test_openai_completion.py --text-model "llama3.2:3b-instruct-q8_0"
```
### OpenAI Completion Integration Tests with together.ai
```
INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct-Turbo" llama stack build --template together --image-type venv --run
```
in another terminal
```
LLAMA_STACK_CONFIG=http://localhost:8321 INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct-Turbo" python -m pytest -v tests/integration/inference/test_openai_completion.py --text-model "meta-llama/Llama-3.2-3B-Instruct-Turbo"
```
### OpenAI Completion Integration Tests with fireworks.ai
```
INFERENCE_MODEL="meta-llama/Llama-3.1-8B-Instruct" llama stack build --template fireworks --image-type venv --run
```
in another terminal
```
LLAMA_STACK_CONFIG=http://localhost:8321 INFERENCE_MODEL="meta-llama/Llama-3.1-8B-Instruct" python -m pytest -v tests/integration/inference/test_openai_completion.py --text-model "meta-llama/Llama-3.1-8B-Instruct"

# What does this PR do?
Currently the instructions for Llama 4 take quite some space before
people can see the overview and other sections about Llama Stack. Moving
this to a collapsed section would make it less verbose.
workflow -
0. Checkout
1. Install uv
2. Install Ollama
3. Pull Ollama image
4. Start Ollama in background
5. Set Up Environment and Install Dependencies
6. Wait for Ollama to start
7. Start Llama Stack server in background
8. Wait for Llama Stack server to be ready
9. Run Integration Tests
changes -
(4) starts the loading of the ollama model, it does not start ollama.
the model will be loaded when used. this step is removed.
(6) is handled in (2). this step is removed.
(2) is renamed to reflect it's dual purpose.
