The Evolution of Code Intelligence: From Models to Agents
A comprehensive analysis of the transition from code-generating foundation models to autonomous software development agents.

Phase 1: Code Foundation Models (The "Autocomplete" Era)
The initial phase focused on training Large Language Models (LLMs) on vast repositories of code (GitHub, StackOverflow).
Key Models: Codex, StarCoder, CodeLlama.
Capability: Function completion, docstring generation, simple bug fixes.
Limitation: Context-unaware. The model only saw the current file or a small window of text. It didn't understand the project structure or dependencies.
