## Choose when

### Choose index-tts if…

- License: index-tts is Other, llm-course is Apache-2.0.
- Tags unique to index-tts: bigvgan, cross-lingual, indextts, python.
- Also covers Vector Databases.

### Choose llm-course if…

- License: llm-course is Apache-2.0, index-tts is Other.
- Requirements: Course materials are available in Colab notebooks; access requires a Google account.
- Tags unique to llm-course: colab-notebooks, course, large-language-models, machine-learning.
- Also covers Evaluation & Observability, Inference & Serving.
- - When you want a comprehensive roadmap for understanding large language models including fundamental knowledge

## When NOT to use index-tts

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.

## When NOT to use llm-course

- - If you only require a quick introduction to LLMs without deep dive into core components
- - When you prefer working directly with commercial platforms that provide complete services rather than following detailed steps on building and deploying models yourself through this course's open,DI
