Show HN: Jacq, a DSL that compiles model and kernel descriptions to CUDA
I was working (with agents) on testing out various attention algorithm ideas I had, and I found that the existing infrastructure/libraries made it more difficult than it should be. So I created Jacq, a DSL and compiler. A jacq file describes a model’s configuration, weights, layers, and pipeline. Jacq turns it into a standalone CUDA inference runtime and a Python weight exporter. Kernel descriptions can also generate CUDA harnesses. The easiest way to try it is the TinyLlama example in the READM

Observed adoption & comparisons
Source votes: 3 votes (Nov 7, 2026 UTC; cumulative since publication) Recent records to compare: “Show HN: Record, branch, and compare command runs in stdlib-only Python” (Show HN, Nov 8, 2026); “meta/astryx” (GitHub Trending, Nov 8, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Adoption decision
Evaluate it against the tool or manual workflow it would replace. The stored record supports discovery; it does not yet establish reliability, lower operating cost or commercial adoption.
Unverified requirements
Not verified: license permissions, required hardware, installation steps, maintenance status and a representative task with its failure cases.
Next test
Choose one real task and a current alternative. Record the commit, environment, input, output, elapsed time and failure behavior; retain the result before recommending adoption.
