bat runs. An Argusic agent installed it in 3.5 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
bat 0.26.1 builds from source, all 293 tests pass, and the binary runs and syntax-highlights input correctly
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- 4 minutes
- Cold machine to finish
- 5 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- `cargo test` exited 0, 293 passed (261 integration + 1 no_duplicate_extensions + 27 snapshot + 1 pretty_printer + 3 doc-tests); `cargo run -- --version` returned 'bat 0.26.1 (7323a75)'; `echo 'test content' | cargo run -- --language=text --paging=never` printed the expected text
- Model tokens used
- 22,567
- Exact commit tested

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Watch the session
The whole run, from a clean machine, at the speed it actually happened. Nothing is cut and nothing is sped up.
A recording of attempt 2, run . The verdict above comes from a different attempt, so read this as one session and not as the current result. The terminal recording it was made from is the evidence, stored with a sha256 fingerprint; the video is a rendering of it. Nothing loads from the video host until you press play.
The end of the recording

Everything works perfectly. No errors occurred. Let me compile the final report.

Everything is clean — no errors, no fixes needed. Here's the final report:Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Nothing broke on the way: zero errors between clone and running.
- Ran without a GPU, so it does not need one to start.
- Licensed Apache-2.0, as reported by its host.
- Measured 3 times, so the result is not a one-off.
What did not, or is not known
- Took 3.5 minutes to install, slower than the median of the 24 comparable projects Argusic has measured.
Of the 25 cli projects Argusic has installed and timed, bat was the 14th fastest to reach a running state, and 23 of 25 reached one at all.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 3.5 minutes after the clone.
- Following its own README: the documented path worked with nothing to fix.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/bat)Questions
- Does bat run?
- Yes. bat runs. Argusic installed and launched it on a clean machine in 4 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test bat?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 7323a7514f76. 3 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test bat?
- The run that produced this verdict cost $0.02: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does bat take to install?
- 3.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does bat need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing bat?
- Nothing did, in the recorded run: zero errors between clone and running.
- How does bat compare with the alternatives?
- Of the 25 cli projects Argusic has installed and timed, bat was the 14th fastest to reach a running state, and 23 of 25 reached one at all.
- Where is the evidence for bat?
- All 3 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
