## What does this PR do? This is a long-pending change and particularly important to get done now. Specifically: - we cannot "localize" (aka download) any URLs from media attachments anywhere near our modeling code. it must be done within llama-stack. - `PIL.Image` is infesting all our APIs via `ImageMedia -> InterleavedTextMedia` and that cannot be right at all. Anything in the API surface must be "naturally serializable". We need a standard `{ type: "image", image_url: "<...>" }` which is more extensible - `UserMessage`, `SystemMessage`, etc. are moved completely to llama-stack from the llama-models repository. See https://github.com/meta-llama/llama-models/pull/244 for the corresponding PR in llama-models. ## Test Plan ```bash cd llama_stack/providers/tests pytest -s -v -k "fireworks or ollama or together" inference/test_vision_inference.py pytest -s -v -k "(fireworks or ollama or together) and llama_3b" inference/test_text_inference.py pytest -s -v -k chroma memory/test_memory.py \ --env EMBEDDING_DIMENSION=384 --env CHROMA_DB_PATH=/tmp/foobar pytest -s -v -k fireworks agents/test_agents.py \ --safety-shield=meta-llama/Llama-Guard-3-8B \ --inference-model=meta-llama/Llama-3.1-8B-Instruct ``` Updated the client sdk (see PR ...), installed the SDK in the same environment and then ran the SDK tests: ```bash cd tests/client-sdk LLAMA_STACK_CONFIG=together pytest -s -v agents/test_agents.py LLAMA_STACK_CONFIG=ollama pytest -s -v memory/test_memory.py # this one needed a bit of hacking in the run.yaml to ensure I could register the vision model correctly INFERENCE_MODEL=llama3.2-vision:latest LLAMA_STACK_CONFIG=ollama pytest -s -v inference/test_inference.py ```
