LLMs

Large language models — APIs, prompting, fine-tuning, and evaluation.

Maturity level: L2Can Build

Six perspectives on LLMs

Roadmap

Core after Python for GenAI, LLMOps, and agent paths.

Architecture

Central inference component in GenAI system design.

Company

Universal expectation in GenAI and LLMOps roles.

Projects

Every GenAI capstone involves LLM integration.

Interview

Deep on evaluation, cost, and production failure modes.

Career

Required for LLMOps, GenAI, and Agentic AI careers.

What & Why

What: Large language models accessed via API or self-hosted for text generation and reasoning.

Why: Foundation of modern GenAI, RAG, agents, and LLMOps systems.

Build this

LLM application with evaluation harness and cost monitoring.

Production reality

  • ! Hallucinations
  • ! Rate limits
  • ! Cost spikes
  • ! Latency
  • ! Provider outages

Interview preparation

  • Prompt vs fine-tune vs RAG
  • Evaluation strategies
  • Cost optimization

Failure scenario: LLM Provider Rate Limit

Symptom
429 errors spike, latency increases
Root cause
Burst traffic exceeds provider quota without backoff
Permanent fix
LLM gateway with rate limiting, caching, and multi-provider routing
