+ Ensure model interpretability through citation, provenance tracking, and source- grounded

**Agentic s Multi-Model Integration**

+ Integrate LLMs within **multi-agent** **architectures** , enabling autonomous reasoning and tool-assisted execution.
+ Work with Agentic AI architects to design **LLM–tool** **interaction** **schemas** and context handoff mechanisms.
+ Build adaptive memory systems combining **vector,** **relational,** **and** **graph** **storage**
+ to support contextual continuity and learning loops.

**Performance, Safety s Evaluation**

+ Establish evaluation pipelines for **accuracy,** **coherence,** **grounding,** **and** **bias** **mitigation** .
+ Implement **reinforcement** **learning** **from** **human** **feedback** **(RLHF)** or in-context learning feedback loops.
+ Design A/B testing frameworks for comparing model prompts, architectures, and retrieval
+ Partner with governance and security teams to ensure compliance with data privacy and ethical AI standards.
