Ante Ships Offline Coding in One Binary

Ante is a terminal coding agent with a local-model path. Evaluate the runtime separately from the patch it produces: a portable executable makes setup easier, but it does not establish what files, credentials or network destinations the running agent can reach.

The project README, checked on 21 September 2026, describes a beta preview for macOS and Linux, with WSL suggested for Windows. It documents a single Rust executable and local inference through a managed llama.cpp engine. Its roughly 15 MB figure refers to the compressed download, not the size of a downloaded model or the total working environment.

What does offline operation require?

The documented offline path uses a local GGUF model with --offline-model. Prepare the executable and model before disconnecting the environment. A local executable configured for a hosted model is not an offline run.

The public repository and distributed binary also have different licensing descriptions: repository source uses Apache-2.0, while the prebuilt executable has separate Binary Preview Terms. Read the terms for the version you intend to use. Do not infer that every shipped component is covered by the repository license.

Our earlier variants described a telemetry environment variable as a sufficient setup step. The current README does not document that setting. This article no longer relies on it as a privacy control. Use an environment whose network access you can inspect and restrict independently of the agent.

How can you test the boundary before real work?

Use a disposable VM with a public or synthetic repository, no forwarded credentials and no extra host mounts. Prepare dependencies beforehand. Choose a small parser fix or help-text change with a test you already understand. Save the starting commit and confirm the relevant test command works before starting the agent.

Write down four facts before the run: the executable version, the local model file, the mounted directory and the network policy. If you cannot explain one of them, resolve it before adding private material. A note in AGENTS.md can express the task boundary, but the VM configuration and permissions must enforce access.

Then run two checks separately:

1. Runtime check. Start the local-model session with outbound access blocked. Record whether the task can proceed, any attempted connections and any missing local dependency. A failed request is useful evidence; do not silently reopen all network access.
2. Patch check. Inspect changed files outside the agent session, run the targeted test and check whether the implementation fixed the intended behavior. Reject unexplained dependency, configuration or permission changes even when the narrow test passes.

This is a proposed evaluation, not a report that we ran Ante or audited its binary. It preserves the distinction between a documented capability and a result you have verified locally.

What should the reviewer receive?

Use the same receipt whether you review in Cursor, Claude Code, Codex or a plain terminal. The originating agent does not change the evidence needed to accept a patch.

Ante trial receipt
Starting commit:
Executable version and source:
Local model file:
Mounted paths:
Network restrictions and observed requests:
Requested behavior:
Files changed:
Targeted test command and result:
Unexpected scripts, dependencies or configuration changes:
Reviewer decision and unresolved limits:

Run git diff --stat, git diff --check and the repository's relevant test command. Read the actual diff, including removed assertions. A clean formatting check does not prove behavior, and a successful test does not establish that no private data left the environment.

When is the trial useful?

Try this when local execution or a reproducible terminal setup solves a concrete problem. Keep your current workflow if the task is a small read-only lookup and another runtime adds nothing. If you later add MCP servers or hosted models, repeat the access review: those connections change the environment you just evaluated.

Keep the first result narrow: one understood patch, one reproducible test and one explicit account of the runtime boundary. Expand only after that evidence is reviewable.

Updated 21 September 2026: Consolidated the Cursor and Claude variants; corrected download size and licensing, removed an unverified telemetry setting, and made the runtime trial explicit.
