What this session would cover

Proposed outline — the mentor finalises the agenda once this topic is scheduled.

  1. 1Why model adaptation & inference optimization matters — the common problem: Teams fine-tune when prompting would do, or serve models far slower and costlier than needed.
  2. 2Core concepts in plain language: Fine-tuning, supervised fine-tuning, parameter-efficient fine-tuning, LoRA, preference optimization, reinforcement learning from feedback
  3. 3Going further: distillation, quantization, pruning, batching, KV caching, speculative decoding
  4. 4Framework walkthrough: Transformer Architecture, Prompt → Retrieve → Generate → Verify, Evaluation Sets
  5. 5Practical workflow, built live: A LoRA fine-tune with before/after evals and a quantization speed/quality comparison.
  6. 6How to measure it: Groundedness, Answer accuracy on an eval set, Latency, Cost per request
  7. 7An illustrative case (a fictional example, not a client result), then live Q&A on your own situation

Who it's for

  • • Students and freshers entering tech
  • • Working developers and engineers
  • • Tech leads and architects

You'd leave with

  • A LoRA fine-tune with before/after evals and a quantization speed/quality comparison.
  • A working understanding of Transformer Architecture and Prompt → Retrieve → Generate → Verify
  • A short list of measures to track: Groundedness, Answer accuracy on an eval set, Latency
