MyPCBench VM images

Pre-baked VM disk images for MyPCBench — a benchmark for personally intelligent computer-use agents (184 tasks, 17 seeded web apps, one canonical persona). Runner + tasks + docs: https://github.com/ljang0/MyPCBench

File What it is
michael_scott.qcow2 v0.1 — current benchmark VM (default). Rebuilt and re-uploaded daily so seeded data reads as current. Byte-identical to the qcow2 embedded in ljang/mypcbench-qemu:latest on Docker Hub; sha in SHA256SUMS, version in VERSION.json.
michael_scott_round78e.qcow2 v0.0 — archived paper baseline (eval-round0). Use only to reproduce the paper numbers.
all_tasks_with_grading.json The 184-task suite with rubrics (mirrors the GitHub repo).
SHA256SUMS, VERSION.json Integrity + provenance for the current upload.
base.qcow2, mypcbench-desktop.tar.zst, mypcbench-michael_scott.qcow2 Legacy artifacts from earlier releases — do not use. Kept for archival; not referenced by any current tooling.

Fetch with no Docker daemon: bash scripts/get-eval-image.sh from the GitHub repo (extracts qcow2 + OVMF via skopeo, or falls back to this dataset).
