# Access to a Foundational LLM

## Prerequisite
Active access to a top-tier foundational LLM — [[entity-chatgpt]], [[entity-claude]], or [[entity-gemini]].

## Why It's Required
Every framework, action, and workflow in this vault assumes a usable model. Free tiers are sufficient to learn; paid tiers (ChatGPT Plus, Claude Pro, Gemini Advanced) unlock the longer context windows and memory features that make [[concept-context-sandwich]] practical.

## Decision
Per [[action-stop-tool-chasing]]: pick **one** as your home base; specialists like [[entity-notebooklm]] and [[entity-suno]] are layered on as needed.
