Protocol9th Protocol puts Fable 5 and seventeen other frontier and open models behind a single coding agent. Reach for the frontier when it counts, drop to fast open models when it doesn't. Metered by the credit, with a memory vault that never leaves your machine.

One subscription, eighteen curated models. Route routine work to fast open models and save the frontier for the hard parts, automatically.
Fable 5, Opus, Sonnet, Kimi, GLM, DeepSeek, Qwen, Gemini, GPT. Switch with /model, or let Auto pick the cheapest model that can do the task.
A fast TUI, a VS Code panel, and a local web session. One agent, the same session, wherever you like to work.
Link an Obsidian-style vault: codebase maps, daily logs, decisions, all plain markdown on your disk, navigable as a knowledge graph.
Fan out explore agents to investigate while the main agent builds. Spawns are permission-gated; burn rolls up to one meter.
Reusable playbooks invoked as /commands and one-click MCP servers. Nothing enters context until you actually use it.
Connect GitHub and Vercel once. Commits, pull requests, and deploys happen right in the session, with your approval on every action.
npm install -g @9thprotocol/cli then run 9p in any project. TUI in the terminal, panel in VS Code.
9p init links a local vault; 9p map builds a wiki of your codebase so sessions navigate a map instead of re-reading files.
Describe the task. The agent plans, edits, tests, and then, with your approval, commits, opens PRs, and deploys.
Credits mirror raw model cost: 1 credit = $0.01 of compute. Budgets pace as 5-hour session windows with weekly caps, and you can buy a reset when you're on a roll.
