AQUA Model Lifecycle Management

Use this skill when the user wants to register, list, browse, or manage LLM models in OCI Data Science AI Quick Actions (AQUA).

Prerequisites

1. OCI Policies must be in place (see aqua-troubleshooting skill for policy details).
2. Object Storage bucket with versioning enabled.
3. Authentication configured (Resource Principal in notebook, or API Key locally).

import ads
ads.set_auth("resource_principal")  # In OCI notebook sessions
# OR
ads.set_auth("api_key")            # Local development

Python SDK Usage

Import

from ads.aqua.model import AquaModelApp
model_app = AquaModelApp()

List Models

# List all AQUA models in a compartment
models = model_app.list(compartment_id="ocid1.compartment.oc1..xxx")
for m in models:
    print(f"{m.display_name} | {m.id} | {m.lifecycle_state}")

Get Model Details

model = model_app.get(model_id="ocid1.datasciencemodel.oc1.iad.xxx")
print(model.display_name)
print(model.lifecycle_state)

Register a Model from HuggingFace

from ads.aqua.model.entities import ImportModelDetails

details = ImportModelDetails(
    model="meta-llama/Llama-3.1-8B-Instruct",
    os_path="oci://my-bucket@my-namespace/models/llama-3.1-8b/",
    compartment_id="ocid1.compartment.oc1..xxx",
    project_id="ocid1.datascienceproject.oc1.iad.xxx",
    inference_container="odsc-vllm-serving",
    download_from_hf=True,
)
model = model_app.register(import_model_details=details)
print(f"Registered: {model.id}")

Register a Model from Object Storage

If model artifacts are already uploaded to Object Storage:

details = ImportModelDetails(
    model="my-custom-model",
    os_path="oci://my-bucket@my-namespace/models/custom-model/",
    compartment_id="ocid1.compartment.oc1..xxx",
    project_id="ocid1.datascienceproject.oc1.iad.xxx",
    inference_container="odsc-vllm-serving",
)
model = model_app.register(import_model_details=details)

Register with Freeform Tags

details = ImportModelDetails(
    model="meta-llama/Llama-3.1-8B-Instruct",
    os_path="oci://my-bucket@my-namespace/models/llama-3.1-8b/",
    compartment_id="ocid1.compartment.oc1..xxx",
    project_id="ocid1.datascienceproject.oc1.iad.xxx",
    inference_container="odsc-vllm-serving",
    download_from_hf=True,
    freeform_tags={"team": "ml-platform", "env": "dev"},
)

CLI Usage

List Models

ads aqua model list --compartment_id ocid1.compartment.oc1..xxx

Get Model

ads aqua model get --model_id ocid1.datasciencemodel.oc1.iad.xxx

Register from HuggingFace

ads aqua model register \
  --model "meta-llama/Llama-3.1-8B-Instruct" \
  --os_path "oci://my-bucket@my-namespace/models/llama-3.1-8b/" \
  --compartment_id "ocid1.compartment.oc1..xxx" \
  --project_id "ocid1.datascienceproject.oc1.iad.xxx" \
  --inference_container "odsc-vllm-serving" \
  --download_from_hf True

Register from Object Storage

ads aqua model register \
  --model "my-custom-model" \
  --os_path "oci://my-bucket@my-namespace/models/custom-model/" \
  --compartment_id "ocid1.compartment.oc1..xxx" \
  --project_id "ocid1.datascienceproject.oc1.iad.xxx" \
  --inference_container "odsc-vllm-serving"

Register GGUF Model (for CPU deployment)

ads aqua model register \
  --model "TheBloke/Llama-2-7B-Chat-GGUF" \
  --os_path "oci://my-bucket@my-namespace/models/llama2-gguf/" \
  --inference_container "odsc-llama-cpp-serving" \
  --download_from_hf True

Supported Inference Containers

Model Artifact Filtering

Exclude unnecessary files during HuggingFace download using wildcards:

ads aqua model register \
  --model "meta-llama/Llama-3.1-8B-Instruct" \
  --os_path "oci://my-bucket@my-namespace/models/llama-3.1-8b/" \
  --inference_container "odsc-vllm-serving" \
  --download_from_hf True \
  --ignore_patterns "['original/*', '*.gitattributes']"

Gated Models (HuggingFace)

For gated repositories (e.g., Llama, Mistral), authenticate first:

export HF_TOKEN=<your_hf_read_token>
# OR
huggingface-cli login
