Newest measured commit vs GHC 9.14.1

How fast is AIHC today?

Each number is AIHC divided by GHC for the same program, backend and optimization level, as a geometric mean over the benchmark suite. Lower is better; 1.00× means parity.

How to read this

Every machine measures every configuration itself, so ratios are comparable across machines even though absolute times are not. Artifact size at -Os and runtime at -O1 stay blank until AIHC grows those profiles. Commits that leave the compiler untouched inherit their neighbour's result and count toward coverage. The timeline shows how each ratio moved over the commit history, the coverage page shows which commits have been measured, and every number links to its commit.
