# What does this PR do?
the LiteLLMOpenAIMixin provides support for reading key from provider
data (headers users send).
this adds the same functionality to the OpenAIMixin.
this is infrastructure for migrating providers.
## Test Plan
ci w/ new tests
# What does this PR do?
When a model decides to use an MCP tool call that requires no arguments,
it sets the `arguments` field to `None`. This causes the user to see a
`400 bad requst error` due to validation errors down the stack because
this field gets removed when being parsed by an openai compatible
inference provider like vLLM
This PR ensures that, as soon as the tool call args are accumulated
while streaming, we check to ensure no tool call function arguments are
set to None - if they are we replace them with "{}"
<!-- If resolving an issue, uncomment and update the line below -->
Closes#3456
## Test Plan
Added new unit test to verify that any tool calls with function
arguments set to `None` get handled correctly

This PR adds support for the require_approval on an mcp tool definition
passed to create response in the Responses API. This allows the caller
to indicate whether they want to approve calls to that server, or let
them be called without approval.
Closes#3443

https://github.com/llamastack/llama-stack/pull/3604 broke multipart form
data field parsing for the Files API since it changed its shape -- so as
to match the API exactly to the OpenAI spec even in the generated client
code.
The underlying reason is that multipart/form-data cannot transport
structured nested fields. Each field must be str-serialized. The client
(specifically the OpenAI client whose behavior we must match),
transports sub-fields as `expires_after[anchor]` and
`expires_after[seconds]`, etc. We must be able to handle these fields
somehow on the server without compromising the shape of the YAML spec.
This PR "fixes" this by adding a dependency to convert the data. The
main trade-off here is that we must add this `Depends()` annotation on
every provider implementation for Files. This is a headache, but a much
more reasonable one (in my opinion) given the alternatives.
## Test Plan
Tests as shown in
https://github.com/llamastack/llama-stack/pull/3604#issuecomment-3351090653

## Test Plan
new unit tests
script now runs successfully
The `/v1/openai/v1` prefix is annoying and now unnecessary given our
clearer focus on how to think about the API surface.
Let's kill it for the 0.3.0 update.
To make client-side changes feasible, we will do this in two parts. This
part adds a new route (sans `/openai/v1`) so the existing client
continues to work since the server supports both.
The next PR will be client-side (Stainless) changes which I will be
making shortly.
The final PR will remove the `/openai/v1` routes.
Note that all these changes will happen rapidly within this release
cycle. The entire set _will be backwards incompatible_.
# What does this PR do?
now that /v1/inference/completion has been removed, no docs should refer
to it
this cleans up remaining references

# What does this PR do?
unpublish (make unavailable to users) the following apis -
- `/v1/inference/completion`, replaced by `/v1/openai/v1/completions`
- `/v1/inference/chat-completion`, replaced by

- `/v1/inference/embeddings`, replaced by `/v1/openai/v1/embeddings`

- batch-completion & batch-chat-completion were only implemented for
inference=inline::meta-reference
- batch-inference were not implemented
# What does this PR do?
simplify Ollama inference adapter by -
- moving image_url download code to OpenAIMixin
- being a ModelRegistryHelper instead of having one (mypy blocks
check_model_availability method assignment)
## Test Plan
- add unit tests for new download feature
- add integration tests for openai_chat_completion w/ image_url (close
test gap)
the commit to be reverted is an public api behavior change to something
we should not support.
instead of allowing silent updates (the caller cannot see the log
messages), we should be sending an error to the caller that they must
first unregister the model before reusing the same name w/ a different
backend.
# What does this PR do?
When listing (and lazily indexing) tools, it's possible for an error to
get thrown by individual toolgroups if for example an MCP toolgroup is
unable to connect to its `mcp_endpoint`.
This logs a warning in the server when that happens, logs a full stack
trace of the error if debug logging is enabled, and just returns the
list of tools from all working toolgroups instead of throwing an error
to the client when a single toolgroup is temporarily or permanently
misbehaving.
The exception to the above is authentication errors, which we
specifically send all the way back to the client as that's how we
indicate to the client that it needs to provide authentication data for
the remote MCP servers.
Closes#2540
## Test Plan
A new unit test was added to test this exception handling, which is run
as part of our regular test suite but also manually run to specifically
verify this fix via:
```
uv run pytest -sv --asyncio-mode=auto \
tests/unit/distribution/routers/test_routing_tables.py
```
To verify the additional debug logging is printing properly:
```
LLAMA_STACK_LOGGING=core=debug \
uv run pytest -sv --asyncio-mode=auto \
tests/unit/distribution/routers/test_routing_tables.py
```
The mcp integration tests were run as below (and by CI):
```
ollama run llama3.2:3b
ENABLE_OLLAMA="ollama" \
OLLAMA_INFERENCE_MODEL="meta-llama/Llama-3.2-3B-Instruct" \
LLAMA_STACK_CONFIG=starter \

# What does this PR do?
Rather than have a single `LLAMA_STACK_VERSION`, we need to have a
`_V1`, `_V1ALPHA`, and `_V1BETA` constant.
This also necessitated addition of `level` to the `WebMethod` so that
routing can be handeled properly.
For backwards compat, the `v1` routes are being kept around and marked
as `deprecated`. When used, the server will log a deprecation warning.
Deprecation log:
<img width="1224" height="134" alt="Screenshot 2025-09-25 at 2 43 36 PM"
src="https://github.com/user-attachments/assets/0cc7c245-dafc-48f0-be99-269fb9a686f9"
/>
move:
1. post_training to `v1alpha` as it is under heavy development and not
near its final state
2. eval: job scheduling is not implemented. Relies heavily on the
datasetio API which is under development missing implementations of
specific routes indicating the structure of those routes might change.
Additionally eval depends on the `inference` API which is going to be
deprecated, eval will likely need a major API surface change to conform
to using completions properly
implements leveling in #3317
note: integration tests will fail until the SDK is regenerated with
v1alpha/inference as opposed to v1/inference
## Test Plan
existing tests should pass with newly generated schema. Conformance will
also pass as these routes are not the ones we currently test for
stability
