Module 4: Introduction to LLM Platforms
What are LLM Platforms?
LLM platforms provide access to powerful AI models that understand and generate human-like text, code, images, and more. These platforms usually offer:
- Pre-trained models (e.g., GPT, Claude, Gemini, Mistral)
- Easy-to-use APIs
- Cloud-based access (no training needed)
Popular LLM Providers
| Platform | Focus | Strengths |
|---|---|---|
| OpenAI | General-purpose LLMs (GPT-3.5, GPT-4) | Chat, code, summarization |
| Anthropic | Safer, explainable models (Claude) | Long context, safety |
| Google AI (Gemini) | Integrated with Google tools | Strong in reasoning, multilingual |
| Mistral | Open-source lightweight models | Efficient, fast |
| Cohere | NLP + RAG friendly APIs | Focused on enterprise use |
| Hugging Face | Open-source model hub | Community, fine-tuning support |
| Azure AI | Enterprise OpenAI hosting | Scalable, secure |
Why Use These Platforms?
| Benefit | Explanation |
|---|---|
| Intelligence-as-a-Service | No need to train from scratch — just use API |
| Plug-and-play APIs | Easy integration with apps, websites, and bots |
| Multitask Capabilities | One model can do Q&A, summarization, translation, etc. |
| Continuous Updates | Models improve automatically in the cloud |
- LLM-related skills are in high demand globally:
- Prompt Engineering
- LangChain / RAG apps
- OpenAI/Gemini APIs
- LLM app integration (chatbots, agents)
Summary
- LLM platforms give access to powerful AI models through easy APIs.
- They are used in almost every modern industry.
- Learning to work with them opens many career and product-building opportunities.
