3. Current System or Situation

3.1 Background, Objectives, and Scope

AIMLFW currently supports supervised and unsupervised pipelines with preprocessing, feature extraction, and batch training. However, it does not natively support LLMOps workloads such as LLM fine-tuning, inference serving, and real-time Q&A capabilities. The goal of this enhancement is to add a LLMOps execution path to AIMLFW, enabling improved performance across various domains.

3.2 Operational Policies and Constraints

• Only containerized, version-controlled LLM components are permitted

• Reproducibility across environments is ensured

• Image signing/scanning is enforced for security

• Simplified rollback and upgrade processes for better uptime

• Resource allocation follows cluster scheduling policies

• Efficient GPU resource management and sharing

• Generated responses must not contain personally identifiable information or subscriber-specific patterns

3.3 Description of Current System

AIMLFW's Training Manager currently schedules machine learning jobs with static templates based on container orchestration. However, it lacks the following large language model operations-specific capabilities:

• LLM-specific Training Interface: Simplified training management tools specialized for large language models

• External Model Repository Integration: Automatic loading of pre-trained models and datasets

• Efficient Parameter Tuning: Memory-efficient model parameter optimization support

• Model Services: Real-time inference service provision for trained LLMs

Currently, manual scripts or external tools are used, lacking reusability and pipeline consistency

3.4 Users or Affected Personnel

• Data Scientists: Design LLM pipelines and perform fine-tuning

• Platform Engineers: Ensure stable cluster deployment and compatibility

• Operations Team: Monitor LLM service execution and validate performance
