# Claude

## What It Is
**Claude** is Anthropic's family of large language models.

## Role in This Source
Claude is referenced repeatedly as the **intelligence engine** powering the Open Brain workflow. Specifically:
- **Conversational interface** — talking to data through MCP-enabled chat (subject to the [[concept-infinite-scroll-problem]]).
- **Code generation** — writing the [[concept-human-door]] web app code from a schema description; see [[action-generate-ui-code]].
- **Cross-table reasoning** — performing [[concept-cross-category-reasoning]] over [[entity-supabase-d21]] data via [[entity-mcp-d21]].

## Pairing
Used alongside [[entity-chatgpt-d21]] as interchangeable LLMs in this workflow. Either can fill the role; the architecture is model-agnostic — which is why the [[concept-ai-flywheel]] applies.
