# What does this PR do? This PR kills the notion of "pure passthrough" remote providers. You cannot specify a single provider you must specify a whole distribution (stack) as remote. This PR also significantly fixes / upgrades testing infrastructure so you can now test against a remotely hosted stack server by just doing ```bash pytest -s -v -m remote test_agents.py \ --inference-model=Llama3.1-8B-Instruct --safety-shield=Llama-Guard-3-1B \ --env REMOTE_STACK_URL=http://localhost:5001 ``` Also fixed `test_agents_persistence.py` (which was broken) and killed some deprecated testing functions. ## Test Plan All the tests.
