A ghost in your shell.Ante is a self-contained coding agent that lives in your terminal and self-organizes. One ~15MB Rust binary fromAntigma Labs, zero runtime dependencies, built to get the most out of any model.
It works like Claude Code or Codex, with none of their dependencies or model constraints. It can also be the optimized core for building your own harness and high-performing assistants.
Every agent claims to be good. Here are numbers you can check:
Ante runsTerminal-Bench 2.1continuously under official leaderboard constraints: 89 tasks, 5 trials each. Each result pins the exact build you can download and links the raw Harbor run for independent audit. Latest full run:82.7%with open-weightDeepSeek V4 Flash 0731(368/445 trials, Ante 0.preview.71, about $68 of inference). DeepSeekreportsthe same 82.7 for this model, measured with its unreleased DeepSeek Harness in minimal mode.
Ante is hand-written Rust with the heavy parts (Grep,git, local inference) embedded in one binary, one process. Across the same 20 parallel tasks in Docker, Ante uses~7× less peak memory,~9× less average CPU, and~5× less disk I/Othan Claude Code.
Ante ships its own inference engine. Point it at a GGUF file and the whole loop runs on your machine: no API key, no account, no internet.
The three are one design decision. An agent you canverify,afford, andrun anywhereis light enough to run by thethousands: the substrate for self-organizing intelligence.
Ante is a single, self-contained binary with no external dependencies: download and run.
Ante works with 12+ providers out of the box:
Configure providers via environment variables (ANTHROPIC_API_KEY,OPENAI_API_KEY, etc.) or OAuth. Add custom providers in~/.ante/catalog.json.
