Course Outline
Introduction and Diagnostic Foundations
- Overview of LLM system failure modes and typical Ollama-specific challenges
- Setting up reproducible experiments and controlled environments
- Troubleshooting toolkit: local logs, request/response captures, and sandboxing
Reproducing and Isolating Failures
- Methods for creating minimal failing examples and seeds
- Stateful vs stateless interactions: isolating context-related bugs
- Managing determinism, randomness, and non-deterministic behaviors
Behavioral Evaluation and Metrics
- Quantitative metrics: accuracy, ROUGE/BLEU variations, calibration, and perplexity proxies
- Qualitative assessments: human-in-the-loop scoring and rubric design
- Task-specific fidelity checks and acceptance criteria
Automated Testing and Regression
- Unit tests for prompts and components, along with scenario and end-to-end tests
- Building regression suites and golden example baselines
- CI/CD integration for Ollama model updates and automated validation gates
Observability and Monitoring
- Structured logging, distributed tracing, and correlation IDs
- Key operational metrics: latency, token usage, error rates, and quality indicators
- Alerting systems, dashboards, and SLIs/SLOs for model-backed services
Advanced Root Cause Analysis
- Tracing through prompt graphs, tool calls, and multi-turn flows
- Comparative A/B diagnosis and ablation studies
- Data provenance, dataset troubleshooting, and resolving dataset-induced failures
Safety, Robustness, and Remediation Strategies
- Mitigation tactics: filtering, grounding, retrieval augmentation, and prompt scaffolding
- Rollback, canary, and phased rollout patterns for model updates
- Post-mortem reviews, lessons learned, and continuous improvement loops
