Models and clients
This page is the status of what connects to what, written down so you do not have to find out after paying. ProofGit is the product this site sells. ProofMEM is a separate product, with its own sign-up at proofmem.com ↗ and its own subscription. Caveau Harness is the workflow that brings the two into one task; it is set up with our team in a guided session.
Each status is written as a word, not shown by colour alone: Available now means you can use it today, Pilot means a private pilot that is not yet open to everyone, Coming soon means planned and not yet usable, and Not offered means not offered or not tested yet.

What the badges mean
- ProofGit runs on your own model key. It writes summaries (and bake-off and cleanup analyses) with the provider you choose under Settings → Connections & BYOK, and serves the evidence to the agents your team already runs. Your provider bills that model use directly; ProofGit does not bill tokens. See BYOK connections and security.
- Gemini models are available through your OpenRouter key. There is no Google connection type; Gemini models are reached through OpenRouter.
- ProofGit works with Claude Code, Codex and Cursor over MCP with a ProofGit token. Set up your agent has the snippets for each.
- ProofGit does not support Google Antigravity yet. It has not been tested with ProofGit.
- Google Antigravity support for ProofMEM is in private pilot. It is not yet open to everyone, and OAuth sign-in for MCP clients is planned to arrive with it.
- ProofMEM does not use Fireworks or Google as model sources. It stores per-phase routing for Caveau Harness; it does not run or pay for model calls itself.
- Caveau Harness routes plan, write and test to Claude, Codex or OpenRouter, on your own Claude or ChatGPT subscription or your OpenRouter key, using the routing ProofMEM saves. It works with Claude Code and Codex, and it is set up with our team in a guided session.

Text description
Claude Code, Codex and Cursor connect to ProofGit over MCP with a ProofGit token. Claude Code and Codex connect to ProofMEM over MCP with an API key. Google Antigravity is a private pilot for ProofMEM, and OAuth sign-in for MCP clients is coming soon. ProofGit calls the model provider you choose with your own key: OpenRouter (Gemini models included), Fireworks, Anthropic, Azure OpenAI, LiteLLM or any OpenAI-compatible endpoint. ProofMEM stores the per-phase routing that Caveau Harness reads, and the harness routes plan, write and test to Claude, Codex or OpenRouter. Cursor has not been tested with ProofMEM, and Antigravity has not been tested with ProofGit.
