Big outputs stay in files
A long log or test run is saved to a file. The model gets a short preview and reads only the lines it needs, instead of carrying the whole thing turn after turn.
Free and open source
Same coding tasks. Far fewer tokens.
Graff is a coding agent that keeps what the model reads small. Harness is the free desktop app that runs Graff, Claude Code, Codex and your other agents in one window.

irm https://codegraff.com/install.ps1 | iexHow it saves
The model reads less. You pay for less.
Most of what a coding agent spends goes on what the model reads. Graff keeps that small.
Search, don't scroll
Code search returns the matching symbols and lines, not whole files, so the model reads what answers the question.
Long chats stay short
As a conversation grows, older turns are summarized, so a long session doesn't resend everything on every request.

Measured on 21 tasks × 3 runs, every run passed, same model on both (one gateway model). Our tasks are not yours: treat this as a ratio, not a promise.

Free credit
A new account or a gift comes with free credit. It pays for a set of lower-cost models, sandboxes and storage, not every model. Buy credits to use any model.

The short answers.
How does Graff use fewer tokens?+
It keeps the model's context small. A long log or test run is saved to a file and the model reads only the lines it needs. Code search returns the matching symbols instead of whole files. Long conversations are summarized as they grow. On the same 21 tasks, Graff used 2.2× fewer tokens than Claude Code on coding tasks and 4.1× fewer on tool-heavy ones.
Why can I only pick some models?+
Free credit, the kind a new account or a gift comes with, pays for a set of lower-cost models, sandboxes and storage. Credits you buy pay for every model. When only free credit is left, a request for another model is refused with a message that names the models it can pay for.
Do I need Codegraff credits?+
No. Sign in with a ChatGPT, Grok, Kimi Code or Z.AI plan and Graff runs on that plan, with its limits. You can also connect your own provider key. Credits are for using many models behind one account, paid as you go.
Where do I see my balance and what I spent?+
In Harness, open Settings → Usage and limits. On the web, sign in to your dashboard.
Is Graff free?+
Yes. Graff and Harness are free and open source. You pay your model provider directly, use a plan you already have, or use Codegraff credits.
What is Harness?+
Harness is the desktop app for macOS and Windows with Graff built in. It also runs Claude Code, Codex, Cursor, Grok, Hermes, Pi and other installed agents in one window. It starts without an account, and nothing leaves your machine for sync until you turn it on.
