Quantum is a minimal, multi-provider coding agent in Python — a Claude Code-style console with slash commands, per-project sessions, and an approval gate for every tool call. Providers are handled by llmkit.
Eleven providers. One console.

What it does
Launch in a directory, talk to the agent, approve its edits. Switch models or providers mid-session. Sessions persist per project.
Launch interactive, run one-shot, or pick up exactly where you left off. Sessions are scoped per project directory.
Everything runs inside the interactive console — switch models, inspect cost, manage context, resume work, without leaving the prompt.
One agent, eleven backends — frontier APIs or a local server on loopback. The provider plumbing is handled by llmkit.
