# What does this PR do?
This PR adds two methods to the Inference API:
- `batch_completion`
- `batch_chat_completion`
The motivation is for evaluations targeting a local inference engine
(like meta-reference or vllm) where batch APIs provide for a substantial
amount of acceleration.
Why did I not add this to `Api.batch_inference` though? That just
resulted in a _lot_ more book-keeping given the structure of Llama
Stack. Had I done that, I would have needed to create a notion of a
"batch model" resource, setup routing based on that, etc. This does not
sound ideal.
So what's the future of the batch inference API? I am not sure. Maybe we
can keep it for true _asynchronous_ execution. So you can submit
requests, and it can return a Job instance, etc.
## Test Plan
Run meta-reference-gpu using:
```bash
export INFERENCE_MODEL=meta-llama/Llama-4-Scout-17B-16E-Instruct
export INFERENCE_CHECKPOINT_DIR=../checkpoints/Llama-4-Scout-17B-16E-Instruct-20250331210000
export MODEL_PARALLEL_SIZE=4
export MAX_BATCH_SIZE=32
export MAX_SEQ_LEN=6144
LLAMA_MODELS_DEBUG=1 llama stack run meta-reference-gpu
```
Then run the batch inference test case.
# What does this PR do?
current text for 'llama stack build' and 'llama stack run' says that if
no argument is passed to '--image-name' that the active Conda
environment will be used
in reality, the active enviroment is used whether it is from conda,

# What does this PR do?
Today, supervised_fine_tune itself and the `TrainingConfig` class have a
bunch of required fields that a provider implementation might not need.
for example, if a provider wants to handle hyperparameters in its
configuration as well as any type of dataset retrieval, optimizer or
LoRA config, a user will still need to pass in a virtually empty
`DataConfig`, `OptimizerConfig` and `AlgorithmConfig` in some cases.
Many of these fields are intended to work specifically with llama models
and knobs intended for customizing inline.
Adding remote post_training providers will require loosening these
arguments, or forcing users to pass in empty objects to satisfy the
pydantic models.

# What does this PR do?
This stubs in some OpenAI server-side compatibility with three new
endpoints:
/v1/openai/v1/models
/v1/openai/v1/completions
/v1/openai/v1/chat/completions
This gives common inference apps using OpenAI clients the ability to
talk to Llama Stack using an endpoint like
http://localhost:8321/v1/openai/v1 .
The two "v1" instances in there isn't awesome, but the thinking is that
Llama Stack's API is v1 and then our OpenAI compatibility layer is
compatible with OpenAI V1. And, some OpenAI clients implicitly assume
the URL ends with "v1", so this gives maximum compatibility.
The openai models endpoint is implemented in the routing layer, and just
returns all the models Llama Stack knows about.
The following providers should be working with the new OpenAI
completions and chat/completions API:
* remote::anthropic (untested)
* remote::cerebras-openai-compat (untested)
* remote::fireworks (tested)
* remote::fireworks-openai-compat (untested)
* remote::gemini (untested)
* remote::groq-openai-compat (untested)
* remote::nvidia (tested)
* remote::ollama (tested)
* remote::openai (untested)
* remote::passthrough (untested)
* remote::sambanova-openai-compat (untested)
* remote::together (tested)
* remote::together-openai-compat (untested)
* remote::vllm (tested)
The goal to support this for every inference provider - proxying
directly to the provider's OpenAI endpoint for OpenAI-compatible
providers. For providers that don't have an OpenAI-compatible API, we'll
add a mixin to translate incoming OpenAI requests to Llama Stack
inference requests and translate the Llama Stack inference responses to
OpenAI responses.
This is related to #1817 but is a bit larger in scope than just chat
completions, as I have real use-cases that need the older completions
API as well.
## Test Plan
### vLLM
```
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

## Documentation
Run a Llama Stack distribution that uses one of the providers mentioned
in the list above. Then, use your favorite OpenAI client to send
completion or chat completion requests with the base_url set to
http://localhost:8321/v1/openai/v1 . Replace "localhost:8321" with the
host and port of your Llama Stack server, if different.

Before this change, bringing up a stack with the `nvidia` template
failed. Afterwards, it passes. I'm testing this like:
```
INFERENCE_MODEL="meta/llama-3.1-8b-instruct" \
llama stack build --template nvidia --image-type venv --run
```
I also ensured the nvidia/test_supervised_fine_tuning.py tests still

# What does this PR do?
This PR makes it possible to switch between agentic and non-agentic RAG
when running the respective Playground page.
When non-agentic RAG is selected, user queries are answered by directly
querying the vector DB, augmenting the prompt, and sending the extended
prompt to the model via Inference API.
## Test Plan
- Launch the Playground and go to the RAG page;
- Select the vector DB ID;
- Adjust other configuration parameters if necessary;
- Set the radio button to Agent-based RAG;
- Send a message to the chat;
- The query will be answered by an agent using the knowledge search tool
as indicated by the output;
- Click the 'Clear Chat' button to make it possible to switch modes;
- Send a message to the chat again;
- This time, the query will be answered by the model directly as can be
deduced from the reply.

this issue arises when loading an mcp_endpoint from run.yaml. the issue
does not manifest for mcp servers added via a running distro server. the
existing tests only cover the case of adding to a running server.
the code for loading run.yaml strips type information from mcp_endpoint,
passing `{"uri": ...}` instead of `URL(uri=...)` along to the resource
provider registration.
## Test Plan
1. run an mcp server
2. add an mcp tool config to the dev.py, e.g.

# What does this PR do?
This PR fixes two issues with the RAG page of the Playground UI:
1. When the user modifies a configurable setting via a widget (e.g.,
system prompt, temperature, etc.), the agent is not recreated. Thus, the
change has no effect and the user gets no indication of that.
2. After the first issue is fixed, it becomes possible to recreate the
agent mid-conversation or even mid-generation. To mitigate this, widgets
related to agent configuration are now disabled when a conversation is
in progress (i.e., when the chat is non-empty). They are automatically
enabled again when the user resets the chat history.
## Test Plan
- Launch the Playground and go to the RAG page;
- Select the vector DB ID;
- Send a message to the agent via the chat;
- The widgets in charge of the agent parameters will become disabled at
this point;
- Send a second message asking the model about the content of the first
message;
- The reply will indicate that the two messages were sent over the same
session, that is, the agent was not recreated;
- Click the 'Clear Chat' button;
- All widgets will be enabled and a new agent will be created (which can
be validated by sending another message).
# What does this PR do?
- provider and their models now live in config.yaml
- better distinguish different cases within a test
- add model key to surface provider's model_id
- include example command to rerun single test case

Add the content to use AMD GPU as the vLLM server. Split the original
part to two sub chapters,
1. AMD vLLM server
2. NVIDIA vLLM server (orignal)

Move the test_context.py under the main tests directory, and fix the
code.
The problem was that the function captures the initial values of the
context variables and then restores those same initial values before
each iteration. This means that any modifications made to the context
variables during iteration are lost when the next iteration starts.
Error was:

Test that context variables are preserved across event loop boundaries with nested generators.
This simulates the real-world scenario where:
1. A new event loop is created for each streaming request
2. The async generator runs inside that loop
3. There are multiple levels of nested generators
4. Context needs to be preserved across these boundaries
