Releases

hal0 is pre-1.0. The active development line ships as pre-release builds; the last cut marked stable is below. Pick the channel that matches your appetite for change.

current dev line

v0.7.3-beta.2

released 2026-06-19

The newest pre-release. Tracks the work documented across the site. Not GA — expect breaking changes between alphas.

last stable

v0.2.0

released 2026-05-23

The most recent release cut without a pre-release tag. Older and more settled than the dev line.

Install

One command on a fresh Linux x86_64 host (Python ≥3.12). NVIDIA/CUDA is not supported.

fresh install
sh
curl -fsSL https://hal0.dev/install.sh | bash

Upgrade & rollback

Self-update verifies a cosign-signed tarball and swaps the current symlink atomically. Two channels:

stable channel
sh
hal0 update --channel stable
nightly channel
sh
hal0 update --channel nightly

Reverts in one step: hal0 update --rollback. See the update & rollback guide.
