Domain-Specific LLM Cost Optimization Strategy & Implementation
- Apr 2
- 3 min read

Duration: 10–14 days following Assignment 1
Type: Individual Assignment
Difficulty Level: Advanced
Marks: 100
This assignment requires you to create an original, domain-specific cost optimization strategy for a real-world LLM application that you research or design. Unlike Assignment 1 (general framework), Assignment 2 demands independent research, creative problem-solving, and domain expertise.
Learning Objectives
Research real LLM cost challenges in a specific industry.
Design novel optimization strategies tailored to domain constraints.
Justify design decisions with cost-benefit analysis and risk assessment.
Implement a proof-of-concept for your strategy.
Communicate your findings in a professional research report.
Task Overview
Choose one of the following domains and create an optimization strategy:
Customer Support Chatbot — Handle 50K queries/month with <$500/month LLM cost
Document Analysis & Extraction — Process 10K documents/month at <$200 cost
Content Generation Platform — Generate 1000 articles/month at <$300 cost
Real-Time Recommendation Engine — Personalize search results for 100K users at <$400/month
Healthcare AI — Analyze patient records compliance-aware at <$600/month
Custom Domain — Propose your own with instructor approval by day 3
Requirements
Research: interview users, analyze real cost data, or use public case studies
Cost Baseline: establish current (or hypothetical) costs and pain points
Innovation: propose 3–5 novel cost optimizations specific to your domain
Proof-of-Concept: implement a working prototype or detailed simulation
Analysis: compare your strategy to industry benchmarks; project cost savings
Risk Assessment: identify risks, trade-offs, and mitigation strategies
Deliverables
1. Research Report (16–20 pages)
Domain analysis and cost drivers
Literature review (3–5 academic/industry sources)
Your optimization strategy (detailed design)
Proof-of-concept implementation or simulation
Cost/benefit projections (1–3 year TCO)
Risk analysis and mitigations
Ethical considerations (if applicable)
2. Jupyter Notebook
Working code or detailed simulation
Cost projections and visualizations
Benchmark comparisons
Sensitivity analysis (e.g., 'If usage doubles, costs increase by X%')
3. Presentation Slides (8–10 slides) for peer review
