WhisperX: Automatic Speech Recognition with Word-level Timestamps (& Diarization)

whisperX runs. An Argusic agent installed it in 2 minutes and hit no errors on a clean machine with no GPU, and the whole session was recorded.
WhisperX 3.8.7rc1 installs, all 12 unit tests pass, the CLI responds with version and help text, and the full transcription pipeline (ASR + alignment) runs end-to-end on CPU with no errors.
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).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
- Install time
- 2 minutes
- Cold machine to finish
- 10 minutes
- Errors hit and fixed
- 0 hit, 0 fixed with no human help
- How the result was proved
- uv sync installed all 135 dependencies; pytest tests/ -v passed 12/12; whisperx --version returned 'whisperx 3.8.7rc1'; whisperx --help displayed full CLI options; transcription pipeline ran end-to-end with model='tiny' on CPU using silero VAD and returned transcribed text with timestamps; alignment model (wav2vec2-base) loaded successfully.
- Model tokens used
- 56,842

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

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.
- Installed in 2 minutes.
- Nothing broke on the way: zero errors between clone and running.
- Ran without a GPU, so it does not need one to start.
- Licensed BSD-2-Clause, as reported by its host.
What did not, or is not known
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
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 2 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/whisperx)Questions
- Does whisperX run?
- Yes. whisperX runs. Argusic installed and launched it on a clean machine in 2 minutes, hitting 0 errors on the way, and recorded the session.
- How did Argusic test whisperX?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 2cfd7b7c5c7b. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test whisperX?
- The run that produced this verdict cost $0.04: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does whisperX take to install?
- 2 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 whisperX need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing whisperX?
- Nothing did, in the recorded run: zero errors between clone and running.
- Where is the evidence for whisperX?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
