IF YOU WANT TO KNOW AI Explained: A Comprehensive Explanation

FAQ’S

Can you combine LLMs?
Yes, LLMs can be combined to balance strengths and weaknesses. One model might draft or handle simple tasks, while another refines, verifies, or manages complex reasoning. This hybrid approach improves accuracy, efficiency, and specialization.
Are all LLMs stateless?
Most LLMs are stateless, meaning they don’t “remember” past interactions beyond the current prompt. Any memory of context comes from re-supplying conversation history in each request. Some systems add external memory layers, but that’s outside the core model itself.
Are all LLMs pretrained?
Yes, all LLMs are pretrained on large text corpora to learn language patterns before fine-tuning. Pretraining gives them general knowledge and reasoning ability. Some are later fine-tuned or specialized for tasks, but the pretrained stage is always the foundation.
What is multiple LLM?
“Multiple LLM” usually refers to using more than one large language model together in a system. This can mean running different models side by side, routing tasks to the most suitable one, or chaining them so one generates outputs and another verifies or improves them. The goal is to combine their strengths—like cost efficiency, accuracy, or specialization—for better overall performance.
How to chain LLMs?

Chaining LLMs means connecting them so each one handles a step in a workflow. You can do this by:

  1. Sequential chaining – one LLM generates an answer, and another refines, summarizes, or verifies it.

  2. Task-based chaining – different LLMs specialize (e.g., one for reasoning, one for coding, one for style polishing).

  3. Controller chaining – a “manager” LLM decides which model to call next, passing outputs as inputs until the task is done.
