* Overview
|
|
The *Context API* (Peripheral Vision) provides the opencortex with the ability to selectively prune and present its memory to the LLM. It implements a **Foveal-Peripheral model**, where the current task is shown in high detail (foveal), while the broader Memex structure is shown as a skeletal outline (peripheral).
