Why can an AI system like OpenClaw use different models without rewriting its own code?

Answer: It acts as a platform that connects to models

It stores all models inside itself — Wrong. Storing all models inside would be inefficient and limit the system to only pre-installed models. OpenClaw does not contain the models themselves.

It acts as a platform that connects to models ✓ — Correct! OpenClaw is an agent platform that sits above models. It communicates with different models through standard interfaces, so it can switch or combine models without changing its own code. This is like a universal remote that works with many devices.

It converts all models into the same format — Wrong. Converting models to a single format is difficult because models are built differently. Instead of converting, OpenClaw uses each model as-is through compatible APIs, preserving their unique strengths.
