# What does this PR do?
https://platform.openai.com/docs/api-reference/moderations supports
optional model parameter.
This PR adds support for using moderations API with model=None if a
default shield id is provided via safety config.
## Test Plan
added tests
manual test:
```
> SAFETY_MODEL='together/meta-llama/Llama-Guard-4-12B' uv run llama stack run starter
> curl http://localhost:8321/v1/moderations \
-H "Content-Type: application/json" \
-d '{
"input": [
"hello"
]
}'
```
# What does this PR do?
2 main changes:
1. Remove `provider_id` requirement in call to vector stores and
2. Removes "register first embedding model" logic
- Now forces embedding model id as required on Vector Store creation
Simplifies the UX for OpenAI to:
```python
vs = client.vector_stores.create(
name="my_citations_db",
extra_body={
"embedding_model": "ollama/nomic-embed-text:latest",
}
)
```
